Synchronising SQL Server and MySQL
I need to synchronise an SQL Server 2000 back end with a MYSQL database on a different box (windows). Can anyone point me in the right direction. I have found a number of resources on synchronising 2 sql server databases but I cant find anything on SQLServer and MySQL.

support for Prepared statement
Hi All, I am using MySQL 4.0.13 and using Connector/j jdbc drivers. What i am looking for is the support for Stored Procedures. Following is what Connector/J documentation says. PreparedStatements are implemented by the driver, as MySQL does not have a prepared statement feature. Because of this, the driver does not implement getParameterMetaData() or getMetaData() as it would require the driver to have a complete SQL parser in the client. I wrote a program to check for Stored Procdures is running fine. Now what i want to knwo is whether MySQL server is supporting Stored Procedures or not?

Re: Data types and the C API
Thanks Paul. After looking a little more closely at the documentation I
figured this out. The example there looks like this:
num_fields = mysql_num_fields(result);
while((row = mysql_fetch_row(result)))
{
unsigned long *lengths;
lengths = mysql_fetch_lengths(result);
for(i = 0; i num_fields; i++)
{
printf(%.*s] , (int) lengths[i], row[i] ? row[i] : NULL);
}
printf(\n);
}
While this does not explicitely say that all columns are returned as
null-terminated strings, it is implied in the printf statement.
Thanks for you quick reply.

I am trying to learn to use the C API for MySQL and have a question. I
have a table that has a primary key defined as int(11). I don't know
what data type this translates to in C. I thought maybe an unsigned int
or an unsigned long. I have this little loop that cycles through the
results of a query and displays the first two columns, the first being
the int(11) and the second a varchar. Here is the code:
result = mysql_use_result(mysql);
while((row = mysql_fetch_row(result))) {
printf(%lu %s\n, row[0], row[1]);
}
The first column is printed as garbage while the second column shows
the data correctly.
INT in MySQL is a 4-byte data type, but that's on the server side. The
result that you're observing is that all values are returned to the
*client* as strings. So you can either print the string using %s, or
convert it to a C int and use %ld (you don't say that your MySQL type is
UNSIGNED, so I'm assuming %ld rather than %lu).
The MySQL 4.1 client/server protocol has some features that allow you to
get back values in binary form without the conversion to string, but
you're probably not using that.
Help?
Thanks.

ssh problem with mysql_real_connect - repost
I think I need a MySQL code guru... I am using the 4.0.12 client library on a Win2k host to connect to a 4.0.13 linux server. If I connect directly to the server using mysql_real_connect, everything runs fine. However, I want to use SSH tunneling. So I set up a SSHv2 tunneling connection from localhost:3306 to server:3306. If I use the command line, i.e. mysql -u foo -pbar -h localhost, I can connect to the remote server via SSH. The same is, if I use tools like SQLyog. But in my program which call the mysql C API, the program freezes. I enable the dbug, here is the output. The program hangs at the last line... Any ideas how to avoid this problem?

RE: Synchronising SQL Server and MySQL
If you are planning to synchronise the data from one to another, that should not be rocket science. However, if you want both database servers to update the data, you're in for something rather heavy. In the easy case, I would probably get the replication feature to output all the database updates, and then write my little parser that would transform dates and other peculiarities from the format of the master to the format of the slave. In the hard case, you will need to do some heavy lifting in order to control concurrency. That is, you will need to make sure databases A and B are identical even when both database servers write data at the same time. It is to the best of my knowledge feasible, but it is definitely not easy to do, and even harder to do without sacrificing performance. Anyhow, that's my 2c. best regards, Jeppe -Original Message- From: Paul [mailto:[EMAIL PROTECTED] Sent: 19. juni 2003 11:31 To: [EMAIL PROTECTED] Subject: Synchronising SQL Server and MySQL I need to synchronise an SQL Server 2000 back end with a MYSQL database on a different box (windows).

Hey there everyone.
I'm having a problem on a MySQL installation (vsn 4.0.12-standard) on
Solaris 8. I've got a few tables that get inserted into maybe 1000-1500
times a day. It seems to be pretty random, but I've seen three or four
times that the database just hangs on the insert.
SHOW PROCESSLIST shows this for the offending process:
| 77 | cpms | localhost | cpms | Query | 8076 | update | INSERT INTO
cpms_orders (order_id, add_timestamp) VALUES ('20030618-3', now()) |
I've still got it running, if anyone has any suggestions for a way to
get more debug data. The mysql software was built with gcc 3.2.2,
again, on solaris 8. If anyone's got any suggestions let me know!
Thanks! Unfortunately I'm gonna have to restart this sooner than later.

Odd thing
We're trying to set up some scripts that will run mysqldump to create export files for each table in a database that can be downloaded to a test server and reloaded.

You're right; you do avoid the problem with the specific sample data I gave you. Sorry about that! But, there are still potential problems because of the comparison of a single concatenated value instead of the separate SKU and STOCK values. In practice, they might not arise because of the formatting of the date/time field. Your subquery does yield, in effect, a good table of maximum date/times for each SKU/STOCK combination. But, you can get a false hit in it with the comparison if a dt_tm value isn't maximum for some stock, but there are other values dt_tm1 and stock1 such that concat(dt_tm,stock) = concat(dt_tm1, stock1) where dt_tm1 *is* maximum for stock1. That was very abstract; I'll supply some more data, with bogus date/time values to illustrate my point. dt_tm, stock, sku, qty A, BB, C, 1 AB, BB, C, 2 -- note that AB is the max(dt_tm) for stock=BB,SKU=C; A is not the max AB, B, C, 3-- note that AB is the max(dt_tm) for stock=B,SKU=C Subselect yields AB, BB, C and AB, B, C; concatenated they are ABBBC and ABBC Select compares ABBC to the above and it matches, so BB, C, 1 is returned (incorrectly) Select compares ABBBC to the above and it matches, so BB, C, 2 is returned Select compares ABBC to the above and it matches, so B, C, 3 is returned Bruce Feist On Thu, 19 Jun 2003, Bruce Feist wrote: Jake Johnson wrote: This is one quick way to get the newest records of a group if you are grouping by the sku and stock. select stock, sku, qty from table where concat(dt_tm,stock,sku) IN ( select concat(max(dt_tm), stock, sku) from table group by stock, sku ) -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
RE: wierd sort query, how do you do it? (sort by ip proximity guess)
Hi, If you convert the IP address into integers, then do an xor (exclusive or), you could call the resultant value the approximate 'distance' between the values. (think of the IP address in binary, any identical bits will result in 0, any differing will be 1. This means that the most significant '1' will be the first dissimilar bit between the two IP addresses. This is really what you are after. However, including any lesser significant bits may well be OK for your application.) OK, so how in SQL You need to create, on the fly ipAddress1 ^ ipAddress2 (order does not matter) where they are both integers (mysql will use 64bit integer arithmetic). You just need to ORDER BY this value.

selecting PRIMARY KEY when there is no unique value
Hi, In a docuement such as Invoice Form, we have a header and a couple of records for the detail. In header table, Invoice# can be the PRIMARY KEY but in detail table, Invoice# is not unique. I think there are two solutions to choose a Primary Key (in MyISAM type) : 1) Adding an id field ( auto_increment ) and choose it as PRIMARY KEY in this case we have to add another index on Invoice# for making relation with the header table 2) There is another field in detail table with timestamp type for keeping the last change on the record. I want to select ( Invoice# + myTimestamp ) for PRIMARY KEY. in this case I don't need to add a new fields ( id ) and another index ( on Invoice# ) to the table. which one do you prefer and usually use? thank -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

My rule of thumb is to use a composite key such as you suggest in (2) in cases where the row doesn't really represent a distinct business entity, but is only used as part of a more complex one. Your example of multiple details within an invoice form falls into this category. If the row is likely to be used on its own, I'm more likely to introduce a new field as a key, in order to make it more convenient to access it directly. In other words, the trade-off is in simplicity of database design (use the existing fields) versus simplicity and efficiency in doing single-row look-ups. The latter is only significant if you expect to be retrieving the row on its own.

I always use a id field with auto increment. It helps for normalization, and makes the code I use to deal with information very generic, grated I've abstracted the code to the point that it has no clue what it's doing, it just gets it done. In my case, I know that the foreign key is always one column and I can short cut the lookup to create the joins, it's it's an index, it's a foreign key, it's this table and index. If the foreign key's index could be anything then It's it's an index, it's a foreign key, it's this table and index, the index are these columns and the code to generate the join is 'interesting'. The other issue is that while your timestamp should be unique when combined with an invoice by whatever rules your dealing with, there's nothing that says it will be in the real world (the one where crazy things happen). By having the id field I never, ever deal with it myself, MySQL always puts the number in there for me and I know it's going to be unique unless MySQL does something it should not do. The id field just takes the guesswork, mess and headaches out of the code (well not *all* of them, but enough) and with the size of disk space these days the extra space isn't much. -- Michael Conlen -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

In header table, Invoice# can be the PRIMARY KEY but in detail table, Invoice# is not unique. I think there are two solutions to choose a Primary Key (in MyISAM type) : 1) Adding an id field ( auto_increment ) and choose it as PRIMARY KEY in this case we have to add another index on Invoice# for making relation with the header table 2) There is another field in detail table with timestamp type for keeping the last change on the record. I want to select ( Invoice# + myTimestamp ) for PRIMARY KEY. in this case I don't need to add a new fields ( id ) and another index ( on Invoice# ) to the table. which one do you prefer and usually use? I always use a id field with auto increment. It helps for normalization, and makes the code I use to deal with information very generic, grated I've abstracted the code to the point that it has no clue what it's doing, it just gets it done. In my case, I know that the foreign key is always one column and I can short cut the lookup to create the joins, it's it's an index, it's a foreign key, it's this table and index. If the foreign key's index could be anything then It's it's an index, it's a foreign key, it's this table and index, the index are these columns and the code to generate the join is 'interesting'. The other issue is that while your timestamp should be unique when combined with an invoice by whatever rules your dealing with, there's nothing that says it will be in the real world (the one where crazy things happen). By having the id field I never, ever deal with it myself, MySQL always puts the number in there for me and I know it's going to be unique unless MySQL does something it should not do. The id field just takes the guesswork, mess and headaches out of the code (well not *all* of them, but enough) and with the size of disk space these days the extra space isn't much. -- Michael Conlen -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED] -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Re: selecting PRIMARY KEY when there is no unique value
Hi Paul, (good to hear from you!) We use (invoice number+date) number as the primary key for the header and (invoice number+body item number+date) in the body of the invoice. We do not allow the same invoice number to be reused on the same day. However they can eventually rollover (ours is a multi location systems with a certain sequence reserved for each location). Body item number a generated sequence. I agree with paul TIMESTAMP is not a cool thing to use. Generating the sequence (there are many methods of doing this, see the MySQL Cookbook by Paul Dubois for some examples including SQL variables or an autoincrement key, program variables, etc) gives a natural and consistant order to the invoice. I hope this helps, Ken Don't use 2). There is no guarantee a TIMESTAMP value will be unique among records with the same invoice number. That means invoice number + timestamp wil not form a PRIMARY KEY. I'd use 1), possibly combining the invoice number with the item id as a composite key. -- Paul DuBois, Senior Technical Writer Madison, Wisconsin, USA MySQL AB, www.mysql.com Are you MySQL certified? http://www.mysql.com/certification/ -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED] -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Remember that this is a binary XOR, not a logical XOR. Mysql does have a binary XOR operator, the '^' operator. So 'ipAddress1 ^ ipAddress2' is the binary XOR between the two values.

RE: suggestions - server options/mysql variables
Hi! All the select statements have indexes on appropriate fields. Mysql appears to run fast, I was just wondering if there was anyway to make it faster.

C API Query Semantics
Using the C API I have written a program that calls mysql_query() on a table with values I know to be in the table. It returns fine and I then call mysql_store_result.

RE: Can we crypt passwords on MySQL
Technically MD5/SHA1 are hashing algorithms and shouldn't be confused with encryption
algorithms like DES, 3DES or AES. From the looks of the document link you gave us it
seems that AES_ENCRYT is the way to go if you want to encrypt the data.
So the command would look something like this:
INSERT INTO t VALUES (1,AES_ENCRYPT(text,password));
So are you saying that the XXX_ENCRYPT function isn't to be used?

It's not recommended because in MySQL 4.1, it returns a different result
each time PASSWORD() is used, with the same input string.

Newbie trying to make root password
Hi, I'm installing and using mySQL for the first time, and it shows. I've downloaded and installed mysql-standard-4.0.13.pkg on my OS X box (bw G3, OS X 10.2.6) I'm following the directions given in the Readme: If you installed MySQL for the first time, *please remember to set a password for the MySQL root user!* This is done with the following two commands: /usr/local/mysql/bin/mysqladmin -u root password password /usr/local/mysql/bin/mysqladmin -u root -h `hostname` password password The first command, /usr/local/mysql/bin/mysqladmin -u root password password, worked fine. The second command gives me errors. I have questions about it, too, if you don't mind answering them. 1. What does this command do? It looks like it defines the root password a second time while specifying the host machine. Why do we do that? 2. Here's what I tried. Please tell me what I should /really/ be doing. I initially typed the command as shown: /usr/local/mysql/bin/mysqladmin -u root -h `hostname` password password with password replaced by the root password I used in the first command. Doing that gave me this error: bash-2.05a$ /usr/local/mysql/bin/mysqladmin -u root -h `hostname` password MYPASSWORD /usr/local/mysql/bin/mysqladmin: connect to server at 'Ungoliant.local.' failed error: 'Host '10.0.0.14' is not allowed to connect to this MySQL server' Next I tried this: bash-2.05a$ /usr/local/mysql/bin/mysqladmin -u root -h `Ungoliant.local' password MYPASSWORD You can see that I got a caret (greater-than-symbol) prompt which I did NOT know what to do with.

RE: Complex SQL involving 10 checkboxes
OK, I've done this.
Problem occurs when a user selects 1 and 9.
The SQL statement I have reads like so:
if (isset($HTTP_GET_VARS['check00'])) {
$age00 = '00';
$s_age00 = penpals.agegroup = $age00 AND;
}
Problem is the AND statement. Some times the user will pick checkbox 1 and 5
but not 2,3,4,6, 7, 8, and 9. And then again there will be times when a user
only uses one check box needing the AND statement on the end, but at other
times the user will select more than one needing an OR statement between the
two checkboxes. Make sense?

Well, if one checkbox represents ages 1-5, another represents 6-9,
and another represents 10-15, then you have the checkboxes add where
clauses. Here is a pseudocode/basic example:
*START WITH A SELECT*
SQL = SELECT * FROM TABLE WHERE
*BUILD THE WHERE CLAUSES*
IF check1 THEN SQL = SQL age BETWEEN 1 AND 5 AND
IF check2 THEN SQL = SQL age BETWEEN 6 AND 9 AND
IF check3 THEN SQL = SQL age BETWEEN 10 AND 15 AND
*TRIM THE UNUSED AND STATEMENT
SQL = left(sql, len(SQL) - 3)
Add some GROUP and ORDER and LIMIT clauses as needed and send the

RE: Complex SQL involving 10 checkboxes
Well first of all, I am obviously having an off day for using AND at all
in my example.
Why not this?
if (isset($HTTP_GET_VARS['check00'])) {
$SQL .= penpals.agegroup = '00' OR;
}
This is probably a question for the PHP general mailing list as it is
more a code question. Essentially you just build the query in chunks. By
the nature of checkboxes you probably just need Ors, not ANDs. You may
need to rip the trailing OR, maybe replacing it with an AND if you need
to add some other condition on the end that needs an AND. Unless of
course someone can belong to more than one agegroup. If so you better
post what the table looks like.

Subject: RE: Complex SQL involving 10 checkboxes
OK, I've done this.
Problem occurs when a user selects 1 and 9.
The SQL statement I have reads like so:
if (isset($HTTP_GET_VARS['check00'])) {
$age00 = '00';
$s_age00 = penpals.agegroup = $age00 AND;
}
Problem is the AND statement. Some times the user will pick
checkbox 1 and 5
but not 2,3,4,6, 7, 8, and 9. And then again there will be
times when a user
only uses one check box needing the AND statement on the end,
but at other
times the user will select more than one needing an OR
statement between the
two checkboxes. Make sense?

Subject: RE: Complex SQL involving 10 checkboxes
Well, if one checkbox represents ages 1-5, another represents 6-9,
and another represents 10-15, then you have the checkboxes
add where
clauses. Here is a pseudocode/basic example:
*START WITH A SELECT*
SQL = SELECT * FROM TABLE WHERE
*BUILD THE WHERE CLAUSES*
IF check1 THEN SQL = SQL age BETWEEN 1 AND 5 AND
IF check2 THEN SQL = SQL age BETWEEN 6 AND 9 AND
IF check3 THEN SQL = SQL age BETWEEN 10 AND 15 AND
*TRIM THE UNUSED AND STATEMENT
SQL = left(sql, len(SQL) - 3)
Add some GROUP and ORDER and LIMIT clauses as needed and send the
resulting string to the server.

Re: Complex SQL involving 10 checkboxes
When I have these kind of settings/testing, I make one text-field and set a specific code ex. age 0-5 [age00-05] age 6-10 [age06-10] and so on - then you reduce the SQL to always read that specific tablefield, and leave the complexity to the program instead. best regards Peter - Original Message - From: Mike Hillyer [EMAIL PROTECTED] To: vernon [EMAIL PROTECTED]; [EMAIL PROTECTED] Sent: Thursday, June 19, 2003 8:57 PM Subject: RE: Complex SQL involving 10 checkboxes Well, if one checkbox represents ages 1-5, another represents 6-9, and another represents 10-15, then you have the checkboxes add where clauses.

RE: Complex SQL involving 10 checkboxes
Why not have each one look like this:
if (isset($HTTP_GET_VARS['check00'])) {
$SQL .= penpals.agegroup = '00' OR;
}
Then after you go through them all, strip the last two characters (the
trailing OR) and then attach and AND
That way it will accommodate any checks, and because you rip the last or
and replace it with an and, you are always Ok for what follows.

Distributed/Fault Tolerant DB operation... possible?
Hi guys, I've been doing some digging around and found some information about master/slave database duplication, but it always sees to focus on increasing query performance by spreading the db out. My situation is that there's a database which must absolutely, guaranteedly be operational 24x7x365 always forever. It must survive and still be operational through power failures, machine locks, and any other manner of scheduled or unscheduled downtime short of a bomb dropping on the co-lo. This would be relatively easy to do if the system was purely read-only: I'd simply duplicate my data across numerous machines and pull queries from them, perhaps on the other side of a load balancer to make no one machine have to be too painfully hit. However, this system is write-heavy (at least 50%, with periods of time reaching 80% or more). Therefore, I need to be able to do a store to one of the servers, and have that store propogate to the other machines (with appropriate software design to compensate for propogation delays and insert-order neutrality). Has anyone done this with two (or more, if possible!) machines? Is it possible to do at the present time? -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

This will allow slave to connect to new masters in the event the original master goes down. 5) All sub masters must use the same binary log file and respect the rotation.

Re: Distributed/Fault Tolerant DB operation... possible?
First get an acceptable outtage rate. Your only going to get so many nines, and your budget depends on how many. The system will fail at some point, no matter what, even if it's only for a few seconds. That's reality. Figure out what kinds of failures you can tolerate based on how many 9's you get and what kinds you have to design around. From there you can figure out a budget. 99.999% uptime is 5 minutes and 15 seconds per year of total downtime. 99.99% is 52.56 minutes and so on. At some point something will happen, and I've never seen anyone offer more than 5 9's, and IBM charges a lot for that. Then, figure out everything that could cause an outtage, figure out how to work around them and give them a budget. Watch how many 9's come off that requirement. If you have to use MySQL I'd ditch PC hardware and go with some nice Sun kit if you haven't already, or maybe a IBM mainframe. Sun's Ex8xx line should let you do just about anything without taking it down (like change the memory while it's running). Then I'd get a bunch of them. Then I'd recode the application to handle the multiple writes to multiple servers and keep everything atomic, then test the hell out of it. There's a lot of issues to consider in there, and you probably want someone with a graduate degree in computer science to look over the design for you. (anything this critical and I get someone smarter than me to double check my designs and implementations). It may be best to just build it in to the driver so the apps are consistent. On the other hand, if you have all this money, look at some of the comerical solutions. This is probably heresy on this list, but hey, it's about the best solution for the needs right? Sybase or DB2 would be my first choices depending on the hardware platform (Sun or Mainframe). The systems are setup to handle failover of the master server. I know for Sun you want to be looking at Sun Clustering technology, a nice SAN and a couple of nice servers. You write to one server, but when it fails the backup server starts accepting the write operations as if it were the master. There's a general rule with software engineering that says if you can buy 80% of what you want, your better off doing that than trying to engineer 100% Think about the networking. two datapaths everywhere there's one. Two switches, two NIC cards for each interface, each going to a different switch. Depending on where your clients are you need to look at your datacenter. Is your database server feeding data to clients outside your building? If so you probably want a few servers in a few different datacenters. At least something like one on the east coast and one on the west coast in the US, or the equivelent in your country, both of whom have different uplinks to the Internet. Get portable IP addresses and do your own BGP. That way if a WAN link fails the IP addresses will show up on the other WAN link even though it's from a different provider. This is just a quick run down of immediate issues in a 24x7x365, it's not exhaustive. Think about every cable, every cord, every component, from a processor to a memory chip and think about what happens when you pull it out or unplug it, then make it redundant. -- Michael Conlen Rick Franchuk wrote: Hi guys, I've been doing some digging around and found some information about master/slave database duplication, but it always sees to focus on increasing query performance by spreading the db out.

Re: mac osx
There are some good Mac clients to access MySQL. I personally use CocoaMySQL for much of my day to day activity. You can find them all on versiontracker.org. YourSQL looks okay too. I agree though, the fancy interface, should you choose to use one of the above clients, is much more useful if you know some basics about how MySQL and Databases in general work. (Not assuming you don't, you may.) You'll need to use Terminal anyway to start the MySQL daemon. Marc Liyanage has some good documentation on MySQL on OS X. http://www.entropy.ch/software/macosx/mysql/ I followed his instructions and it works beautifully on my machine.

How do you think the key should be used? You have a key on status,
but you're asking for a wide range of status values. Presumably
MySQL thinks (probably correctly) that using the index to find a
range of status values from 'AA' to 'VQ' is no faster than doing a
full table scan.
I could be missing something, but if so it would help if you could
explain how you expect the key to be used.

If it truly ran fine for a few days and then you couldn't run the client, you may have another problem. If you rebooted the box, mysqld may not have automatically started. So, all of the sudden, the client can't connect to the socket since it is not there as the server is not running.
