Re: Can I have two (or more) different SQL-databases on the same server?
Hi, Can I have two (or more) different SQL-databases running at the same time on the same server (or same computer)? Does it varies between the systems? And if I can, are they all available to PHP at the same time? If you *really* mean different databases, then yes, no problem (one of my production machines has 5), and they will all be available to PHP, subject, obviously to permissions. If you mean can you have more than one instance of MYSQL running, that's different. You may be able to (I've no experience here), but why would you want to?

I posted such a message myself on Jan 18th and I am still getting this kind of problem since then. It may run several days without problem or crash 3 times within 2 hours.

I use MySQL with 2 web front-ends coded in Perl (mod_perl) and this problem appeared when I switched the backend from miniSQL to MySQL (going back to miniSQL is not an option since it has its own limitations). My configuration is close to yours (Linux RedHat 6.2, 2.2.14 kernel; PIII-733, 2Gb RAM) and MySQL load similar (between 300 and 500 persistent connections, about 300 queries/s).

It also has plenty of free space. I made sure to direct the temporary files to a partition with space. So my question is, why is this happening? How can I fix it? I haven't tried safe-recover yet as I get the impression it would take a LONG time to complete, and although the documentation says it uses less disk space, I don't know if it would help. I am now just going to do the alter table on the full database, which will mean it makes a full copy, inefficient, but hopefully it will work. But I would like to know what causes this error and what I can do to fix it. Are there other good ways of importing lots of data into a table and then building the index later?

You can achieve a good speed increase using mySQL as a back end to Access. The amount of performance improvement will depend greatly on good use of indexes. Be sure that anything included in a WHERE clause in an Access linked table is an index in mySQL. All tables should have primary keys and you'll find that form interfaces work better if all tables also include a TIMESTAMP(14) column. We've had very good success with porting Access applications to a mySQL backend here simply by uploading the tables into the mySQL server and then re-linking them as ODBC linked tables in Access. [EMAIL PROTECTED] wrote: We're looking at moving a web-based application currently built with Microsoft Access and Cold Fusion to a real database platform. I've only just started poking around mySQL, so I'm not really up on its capabilities. One of the things this application relies on fairly heavily is stored queries (aka stored procedures and/or views, depending on what platform you're coming from). There are sometimes five or six layers of SQL, with one query using other queries for their data, between the tables and what the user eventually sees. Poking around the documentation, it appears that mySQL doesn't support that sort of thing. Do I have that right, or am I missing something important? Even if I can't get deeply layered queries with mySQL, is there a relatively painless way of building them with some other tool (say, php or perl and the appropriate modules)? Am I likely to get a significant boost to performance if I keep Access in the middle for queries but move the tables to mySQL? - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Re: Database/table encryption

By 'secure' they mean that even if someone gains root access on the server, the data in the database can't be compromised (obtained). I can think of a couple of ways to do this, but I don't know if they're practical. The first is to have MySQL store the tables and such in an encrypted fashion, at the file layer. Can anyone else offer any alternative suggestions, or some guidance? Most standard way is prorably having encrypted filesystems support in kernel (http://www.linuxi.org) and then having MySQL databases on it.

Re: A few queries about optimising MySQL variables

If your table_cache is lower than the actual number of tables in use (in my case 64 versus 70), then when a table that is not already open needs to be used, MySQL must open it, and so increments the Opened_tables status variable. In an ideal world, Opened_tables would be nil (or very low), as MySQL would already have all the tables open, yes? Yes. Queries that require a full table scan (those which don't or can't use indexes). "Sequential scans" can mean "full table scans". So, basically, a large record_buffer is only useful if your queries operate in a non-efficient fashion by not using indexes? I try to optimise all of my queries, and I'm pretty sure that reducing it to something like 4Mb would be alright. Basically, yes. But there are cases in which a full table scan is the fastest way to do something, and MySQL may decide to do that. You didn't mention the key_buffer. If configured well, you can get a great performance boost from it. My key_buffer is currently at 128Mb, but I'm considering upping that to 192Mb or maybe even 256Mb. Probably the former, as I don't have tables with hundereds of thousands of records to contend with. Sounds like you've got a good understanding of what's going on now.

CASE..END not working in ORDER BY clause?
hi there! it seems logical to me that using CASE...END in an ORDER BY clause ought to work. i can set up a CASE statement in a SELECT: SELECT CASE test.ID WHERE 1 THEN 2 WHERE 2 THEN 1 END AS c and i get the expected output. however, if i then try to move the whole case statement into the clause (ORDER BY CASE test.ID...END), then mysql seems to completely ignore the CASE...END instead; i.e. the table is sorted as it would be without the CASE...END (if i do ORDER BY CASE test.ID...END, test.name - then it will simply be ordered by test.name). additionally, if i leave the SELECT CASE...END AS c and then try to ORDER BY c, mysql complains that column c is not known. any ideas on what i'm missing here? this is using 3.23.32, compiled today. it did the same thing with a .27-gamma release. thanks. -damon - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Idea: Automated server tuning?
Hi all, In the light of my recent experiences with tuning my MySQL server, I had a few ideas about how getting optimum performance from your MySQL server could be made a little easier for everyone. My idea is to have some kind of facility to 'auto-tune' the server configuration variables for you. Although tuning manually seems to be more trial-and-error than deduction and formulation, I'm sure that it's possible to work out rules for what needs to be configured and how from information that is usually readily available about the environment that the server is running in. Here are some examples of what I mean: 1. The key_buffer_size variable could probably be fairly accurately set according to available system memory, sizes of indexes on current tables and by analysing EXPLAIN output from common SELECT queries from logs. 2. Parameters that are very OS-specific, such as flush_time for Win9x systems and thread_concurrency on Solaris. 3. Things like tmp_table_size could be set according to available system memory and answers from the user about what kind of disk subsystem they're using (maybe not even this - a simple disk benchmark may provide useful info here). These are just initial thoughts, so I could be wrong, but I'm sure there's a grain of sense in there somewhere. What I envisage is something that could operate in either (or maybe both) of two ways. Overall it would be some kind of program that will grab information about the system (i.e. CPU type, RAM, disk subsystem, etc.), status and variable information from MySQL and recent logs it is given access to - maybe even a few answers from the user about things it can't deduce on it's own. It could produce a report about what things are most significant about your usage and environment and some recommendations for configuration settings (maybe even implement them for the user, although that may be a bit *too* automated). It might either be something that you run on a one-off basis, or something that you run persistently over a period of time that would record information it needs at regular intervals in order to get a 'bigger picture' and make more informed recommendations. I'd like to know what people think - whether it's just crazy and would never be feasible or if it could genuinely be something possible and something useful. If it only inspires the MySQL developers to contemplate something like this for a future version of MySQL, then that would great. But otherwise, I like to think that someday I might be able to accomplish it, given some more experience and the time to research everything (and of course, learn some C/C++).

Problem with update logging under Solaris
I am running MySQL 3.22.32 on a sun enterprise server, but I am having problems with update logging. When update logging is specified in the /etc/my.cnf file and the MySQl process restarted logging will commence but will stop after a few hours (the number of hours is variable!). Connecting to the MySQL server and doing a 'show variables' shows that update logging is switched on. However no logfile is written even if a specific flush-logs comand is issued. There is a script regularly rotating the logfile (every 5 minutes) for replication purposes but no other log rotation happenening. There is no filespace issue (the logfile is being written to an 80 GB drive that it only 28% full) nor is there a permissions problem (after all the logfile is written when the server is started). Restarting the MySQL process will restart logging but it dies after a few hours once again. Has anyone out there had this problem or better yet know how to avoid it??? Unfortunately upgrading to MySQL 3.23 is NOT an option.

Re: select-Problem
Sir, Joe Celko's 'SQL For Smarties' has two chapters devoted to tree problems. After a quick look in the book, it appears to me that you can use one of his algorithms if you restructure your table and adapt his SQL to the MySQL dialect. See the chapter on Nested Set Models. Bob Hall Hi, I have a recursive Problem. I have a Table with columns "id", "name" and "pid". E.g: name1 name11 name12 name121 name122 name13 name2 name21 In the Table it would look like: id, name, pid 1 name1 0 2 name11 1 3 name12 1 4 name121 3 5 name122 3 6 name13 1 7 name2 0 8 name21 7 Is there any select statement, which give me the path e.g to the id 5? I want to provide the 5 and will get the following: id5 (pid3) - id3 (pid1) - id1 (pid0) name122 - name12 - name1 Do you have any idea?

mySQL 3.23.32 memory optimization ....
Hi, firstly thanks for your answer, [EMAIL PROTECTED] works very very well ! We are doing a very hard work with mySQL , used as main database inside our ERP Oasi. (instead of DB2 or ORACLE). We have a performance problem with memory usage. the process accesses to database via ODBC (iodbc2-12+myodbc2.50.22) and all seems to be OK, except for the memory usage. We have a table with 1,5 millions of record that a client program needs to scan and the client process size grows up because it reserves memory to store rows. do_query(), inside execute.c calls mysql_store_result(), and in this way all the data is transefferd to the client. I tryed to uncomment the portion of the code above in execute.c having: . if (stmt_options.cursor_type == SQL_CURSOR_FORWARD_ONLY) stmt-result=mysql_use_result(stmt-dbc-mysql); else stmt-result=mysql_store_result(stmt-dbc-mysql); . and I have set the correct option before the SQLPrepare() statement: SQLSetStmtOption(vst-startHstmt,SQL_CURSOR_TYPE,SQL_CURSOR_FORWARD_ONLY); I don't need the scrolled cursor, so in this way the driver calls mysql_use_result saving a lot of memory. It works, but when I execute another query, building a different statement, with or without setting the statement option for the cursor type, (note that the code perform another SQLAllocStatement()), i got this error: --- SQL error : -1 line number: 107 SQL state : S1000 native error code : 2014 [TCX][MyODBC]Commands out of sync; You can't run this command now the query is: [select * from archcont where codcon = ?] archcont is another table, a little one. I know that the comment in execute.c says: /* We can't use USE_RESULT because SQLRowCount will fail in this case! */ but i don't need to use SQLRowCount when i set the cursor type as SQL_CURSOR_FORWARD_ONLY, of course. Anyway, if there is another method to save memory, please let me know how I can do it, without change my code (if it is possible). Regards marcello marcello giovagnoli Logical System s.r.l.

Serious MySQL internal deadlock
It seems that MySQL 3.23.32 has an internal deadlock problem, causing the database to stop responding. Situation: 6 processes (each on a different system) connect to a mysql database and insert various system data into a set of MyISAM tables. Each process uses the user 'logdaemon' which has insert privilege to the required tables. Data is extacted by php scripts using the user 'logreader', which has select privilege to the required tables. It happens at least once a day that MySQL stops responding. First I did assume that missing locks could cause the problem, so I modified all accesses to the database to use read and write locks on the required tables. This didn't help. If you look at the attached output of the 'show processlist' command the most obvious thing to see is that 2 IDs are in state 'System Lock' on the same table. Killing the threads doesn't help. The thread state changes to 'killed' but that's it. Regular shutdown of MySQL is impossible, all MySQL PIDs must be sent the TERM signal. Note that even as MySQL is compiled with BDB support there are only MyISAM tables. All inserts are "regular" inserts, there is no 'insert delayed'. the amount of inserts/day of all tables of this database is about 1. The amount of selects is currently much lower (less than 1000/day). Thus concurrent inserts and selects to the same table may easily cause a denial of service condition. The only perhaps non-standard thing I did here was not to set a default database but to address the tables directly (db.table) which may be, ahem, not usual but still is a valid way to access a table. I'm going now to change this, i.e. all connecting processes will set the database and see if the problem persists. Nevertheless this is a somewhat bad situation that should be resolved as soon as possible. As a side effect of this problem I had the database first set to replicate in Robin Round manner between three systems. Unfortunately, when the above situation happens and MySQL must be killed, replication is killed for good, too, as the slave thread of the killed MySQL database will just loop in a 'waiting to reconnect after a failed read' state after MySQL restart. Thus the current replication setup is already that there's just two shadow databases for the master that handles all reads and writes. This leads to an additional thought: What happens to replication after a power outage or a system crash? Yes, I' using a ups but it can happen, that these things fail, causing a home made power outage. It wouldn't be too good if a non-standard shutdown of a slave would mean to restart replication from scratch. Andreas Steinmetz D.O.M.

Re: how to get the union of the values in a SET column ?
I was hoping that since each member of the SET really represents a number, that there would be some bitwise operation that would painlessly produce all the members of the SET that appear at least once. Sir, I apologize for taking so long to respond. I was moving some furniture this weekend and dropped a desk on my keyboard. No worries Bob. I've only just got back online myself (though my excuse is more hedonistic - was snowboarding). You are right about SETs, and I am blind. The obvious solution is the bitwise or. MySQL has a summary function called Bit_Or(). Unfortunately, it returns a decimal representation of the result, so you have to massage it a little. SELECT Bin(Bit_Or(column_name)) FROM your_table; Excellent. I actually tried the Bit_or and Bit_and() functions but must have screwed up on my binary conversion aaah! b/c the results I had didn't seem to make sense. The Bin() function is very handy. The bits are in reverse order; if your SET declaration includes a, b, c, and d, and you columns include all but b, you'll get 1101 from the SELECT statement. This is fine if you're going to process the bits in your client. But if you want to display the bits in MySQL in the same order as your SET declaration, you can use Reverse(Binary(Bin(Bit_Or(column_name which will give you 1011. Awesome. That's just the ticket.

Re: mySQL 3.23.32 memory optimization ....
Hi Monty,
Why do you need to retrieve so many rows to the client? Can't you use
LIMIT to restrict the number of result rows?
The point is that the program scans the entire table and process each row
in a diffrent way, executing other queryes inside the main SQLFetch() loop.
Someting like this:
SQLExecute(hstmt1,query1)
while(SQLFetchRow(hstmt1) == SQL_SUCCESS )
{
...
...
SQLExecute(hstmt2,query2)
while(SQLFetchRow(hstmt2) == SQL_SUCCESS )
{
..
}
}.
Perhaps the code should be rewritten, to reflect the right way
to write code that uses database, but in my source code i
don't use ODBC directly, it is embedded, I have someting like this:
dbSetKey(Db,"table1","column1,column2");
.
dbSetValue("table1.column1", value);
...
err=dbStart(Db,"table1")
while(!err)
{
.
.
err=dbStart(Db,"table2")
while(!err)
{
dbNext(Db,"table2");
}
dbNext(Db,"table1");
}
dbStart() build the right query with the where condition and order by
using ODBC.
For each running program I have one instance of mysqld connected to.
There are up to 300 programs written in this way and they
works, I can't modify them in a few time.
Are you sure you close the statement before doing another ?
The reason this happens is that mysql_free_result() is not called
for the previous query and there is still on the connections data
for the previous query.
Executing mysql_free_result() will quickly discard all rows from the
server so that you can issue a new command against it.
Reading the manual :( It seems that i can do this ONLY using
mysql_store_result(), because each mysqld instance can do
only one query at a time, is it correct ?
If yes, I need some way to reduce the client memory usage,
processing big tables.
I can implement something build a select with limit n1,2n
re-run the query when SQLFetchRow() fails.
I don't have notice how the other databases works in this cases.
In my opinion the right way to work around this problem should be
to use a temporary file to store results for the big tables, forcing this
option with a parameter as SQL_BIG_TABLES=1, in this case
mysql_store_result() can store the result in a file, i can issue the
SQLFreeResult() and build another query.
What do you think about ?
Which version of MyODBC do you use?
myodbc-2.50.22
If you have an very old MyODBC versions which includes an old
mysqlclient lib this may explain your problems; Older
mysql_free_result() versions didn't read the old result from the
connections and because of this one would get the error message you
got if one didn't read all rows from the result before calling
mysql_query() again.
Thanks, Monty

Re: Large text searches
Geoff Coffey wrote: I am new here... I am in the process of migrating a site built with FileMaker Pro to MySQL and PHP mostly because filemaker's web capabilities are too limiting. In one situation, we have a database of about 20,000 rows that contains two text columns. One is the full text of a resume and the other is the full text of a cover letter. I'm trying to decide how to enable searching from a web form. I've not actually tried it, but I suspect using "LIKE" will be lousy. In Sybase it certainly would be. I found a thread on this list discussing just this, and the suggestion was made that I create a few tables to store keywords and map them to record ids etc. My problem with this is it makes it impossible to do searches on a phrase. I think the users would often search for "Microsoft Word" for instance, and it would find every candidate that mentions "Microsoft" and "Word", but not necessarily together. But it would be acceptable to limit it to word searches if need be (filemaker doesn't support this now in a fast way anyway). Are there any other options than this? You can support phrases, using the keyword method you mention by first generating a list of all docs that have your words using they keyword method, you can then use LIKE '%Microsoft Word%' against the narrowed list of documents. - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

MySQL - Filemaker Tip
Hi all, I just came across this little tid-bit of information today and thought I'd share it, seeing as it's potentially very useful to anyone trying to export records from MySQL and then import them into a 'repeating' field in Filemaker Pro. When importing a text file of single-field records, Filemaker considers the ASCII character 29 to be a repeating field seperator. So, you may wonder how you can export records terminated by ASCII-29 using MySQL... You can get ASCII-29 by using hexadecimal representation - it's simply 0x1d. So, to export a certain field like this, you simply do: SELECT field FROM table WHERE something = 'foo' INTO OUTFILE '/path/to/whatever.txt' LINES TERMINATED BY 0x1d Then just transfer it to your Mac/PC and import this text file into the repeating field of the record you desire. Et voila!

Actually I did avoid using lock tables but got hit by this problem. Thus I
tried with lock tables.
Using supplied binaries is no choice as for certain reasons all systems
involved are completely built from source.
I can't really see a reason why a slave being updated should lock the master
for good. Nevertheless there's just one programmable switch between the master
and the slaves involved and the network speed is 200MBits/s (channel bonding) so
this can't really be the reason for the problem.
If I can do anything to help to sort this out I'll happily do so.

Re: myODBC question
Speaking as one who tried working with such a connection, FORGET IT. While entering data, I might get all or half a record entered when the message arrives telling me the information cannot be posted, because another user was editing that record (which I could tell was simply NOT the case), and I had the option of either dropping my input, or put the whole record in the past buffer. Occasionally, I would get lucky and get a whole record entered and saved, but mostly, my datbase was getting filled with gaps. Get phpMyAdmin. It is far more reliable solution.

I have read on replication, just recently. What I could gather from the manual: The replication creates an exact mirror of a database on another server using a parent server to a daughter server method. Which brings up two issues: How long is the lag? How could I use this to load balance? My thoughts are: If the lag time is insignificant than I could use a php script to round-robin connect between the two db servers and load balance selects that way, but inserts _have_ to be done to the parent. Now, using php and theoretically if both servers are identical, when the parent was disconnected I could have the inserts go directly to the daughter server, but then when the parent comes back-up they need to be able to synchronize. Any ideas on how to do this? I just need some way for two servers to provide the exact same information at near perfect real-time and if machine A goes down then machine B will take all requests and then re-sync when machine A comes back online. It seems like this is impossible without some sort of two way replication available. Any input is welcome. Thank You! .:: Nathan Cook [ [EMAIL PROTECTED] ] ::.

you can tell
dear Sir :
MySQL 3.22 on my linux 486 PC seems work so good. when I compile
a simple C API programe which catched from the MySQL tutorial, it
chokes at the end of compile process . the programe is as follows:
#include stdio.h
#include mysql.h
#define def_host_name NULL
#define def_user_name NULL
#define def_password NULL
#define def_db_name NULL
MYSQL *conn;
int main(int argc,char *argv[])
{
conn=mysql_init(NULL);
mysql_real_connect(
conn,
def_host_name,
def_user_name,
def_password,
def_db_name,
0, /*port defaut*/
NULL, /*socket default*/
0);/*flag*/
mysql_close(conn);
exit(0);
}
I compile as follows:
gcc -o client my_simplest_prog -I/home/MySQL/MySQL/include \
-L/home/MySQL/MySQL/lib \
-lmysqlclient
then I get :
/home/MySQL/MySQL/lib/libmysqlclient.a(my_open.o)In function 'my_open':
my_open.o(.text+0x14):undefined reference to 'open64'
/home/MySQL/MySQL/lib/libmysqlclient.a(mf_format.o)In function 'fn_format':

/home/MySQL/MySQL/lib/libmysqlclient.a(my_open.o)In function 'my_open':
my_open.o(.text+0x21):undefined reference to 'fopen64'
nothing left to do with the situation, I beg your help. anyway I'm a
newcomer. thank you very much.

query optimization suggestion
When using mySQL I've learned to avoid OR in any queries as much as possible . Almost always this causes a major speed decrease. Consider this table: CREATE TABLE test( userID int, # (non-unique) testID int, # (non-unique) PRIMARY key(testid,userid) ); Suppose this table is populated with 1,000,000 rows. Then do this: DELETE FROM test WHERE userID= AND testID20 OR testID80; This query is EXTREMELY slow becasue it looks at every row in the DB. A significant improvement can be acheived by splitting it into 2 statements: DELETE FROM test WHERE userID= AND testID20; DELETE FROM test WHERE userID= AND testID80; On real data I've acheived at least a ten fold increase doing this. This is easy to optimize from the client side, however, I don't see any reason why this optimization can't or shouldn't be build into the server.

But it would be acceptable to limit it to word searches if need be (filemaker doesn't support this now in a fast way anyway). Are there any other options than this? This is a big software enginering topic... If you want to do the search with LIKE, do it, but the performance will decrease as soon as you put more and more texts... By the other way, using lists of words would be ok, but has some problems, one is the "Microsoft Word" that you say. I think the more inexpensive (in time and money) way to implement this is using the LIKE clausure but making backups of the query in a "cache" so if other user ask about something like that the system will bring it back in a flash... Then you can search even in the "cache" database... Making search engines is not a trivial thing, but this may be an aproach... -- Gonzalo Aguilar.

duplicating rows
Hello list, After searching the documentation on the site, as well as the archives, I have yet to find the answer to this question. If I have overlooked it somewhere, just point me in the right direction. The question: I have two tables, set up exactly the same, except the names of the tables are different. Table 1 is called: active_users Table 2 is called: deleted_users When "joe_smith" wishes to be deleted, I want to remove his entry from the active_users table, and place it into the delete_users table, with exactly the same information. Something like: replicate * from active_users where user_name = "joe_smith" into table deleted_users; All entries in Table 1 are unique by user_name (joe_smith in this case), but such is not the case in the deleted_users (there is more than one joe_smith in the world, if one cancels, we need to allow another one to signup), which is why I can't just add an extra column to tell if the user is active or not. I could do a select from active_users, store the information, then insert into deleted_users, then delete from active_users, but that is three steps when it seems there should be an easier (more efficient) way. Any ideas or links to archives or documentation is appreciated. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Aaron Williams [EMAIL PROTECTED] Dev.

Re: Binary data
Hi Barry,
I do not know what do you use for feeding your database, but in Perl you
shoud use the DBI module, and insert the binary data through bindings.
use DBI;
use strict;
...
my $dbh = DBI-connect("dbi:mysql:image_db", "user", "password") || die
"$DBI::errstr\n"; # connect to the database
...
my $sth = $dbh-prepare("INSERT jpeg_table SET size_x = $size_x, size_y =
$size_y, image_data = ?;") || die "$DBI::errstr\n"; # prepare the insert
statement, replacing the image data with a question mark
$sth-bind_param(1, $image_data); # binding the binary data
$sth-execute() || die "$DBI::errstr\n";# executing the insert
...
$dbh-disconnect(); # disconnect

Re: query optimization suggestion
In the last episode (Feb 01), Michael Griffith said: CREATE TABLE test( userID int, # (non-unique) testID int, # (non-unique) PRIMARY key(testid,userid) ); Suppose this table is populated with 1,000,000 rows. Then do this: DELETE FROM test WHERE userID= AND testID20 OR testID80; This query is EXTREMELY slow becasue it looks at every row in the DB. A significant improvement can be acheived by splitting it into 2 statements: DELETE FROM test WHERE userID= AND testID20; DELETE FROM test WHERE userID= AND testID80; Avoiding ORs is a good idea, but I don't think your example demonstrates it. The real problem is ORs on two different columns. You have: "(testID20 AND userID=) OR testID80", which can be optimized with a two-column index on (testID,userID). A better example would be "DELETE FROM test WHERE userID= OR testID=". On real data I've acheived at least a ten fold increase doing this. This is easy to optimize from the client side, however, I don't see any reason why this optimization can't or shouldn't be build into the server. Whenever an OR can be split into two separate queries on the same index this optimization should work. What you're suggesting here is splitting a query into a UNION of two smaller queries, essentially. But this is not always the best way. Keep in mind that your DELETE example doesn't have to worry about records that are true for both halves of your OR (since the record would get deleted by the first statement). If it were really a SELECT query, mysql would have to run the first half of the query, remember all the record numbers, then run the second query and make sure that no duplicate records are returned: SELECT * FROM test WHERE userID= or testID=; i.e.full table scan would become (if mysql supported UNION): SELECT DISTINCT * FROM ( SELECT * FROM test WHERE userID= UNION SELECT * FROM test WHERE testID= ); i.e.random record pull based on userID index + random record pull based on testID index + mergesort + remove duplicate records If there is a lot of overlap between the two OR clauses, or the percentage of returned records is high relative to the size of the table, doing a full table scan would be faster. -- Dan Nelson [EMAIL PROTECTED] - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Re: duplicating rows
Can be done in two steps, but not in one: insert into deleted_users select * from active_where where username='joe'; delete form active_users where username='joe'; what you mention about usernames not being unique in the deleted_users table is not a problem as long as you don't have a primary or unique key on username.. but you should make some primary key in the delete_users table, an auto_increment or something for maintenance purposes. Right, there is an auto_increment column in the active_users, which will get carried over into the deleted_users table. Since each entry in the active_user will be auto_incremented, all of the rows in the deleted_users will have a unique identifer as well. At any rate, I guess two steps are better than three.
