DP I am brand new to MySQL, and trying to get up to speed as fast as possible.
DP I have successfully installed both MySQL 3.23.47 and MyODBC 2.50.39. I am
DP using VB6 and ADO in combination with MyODBC to connect to a database I have
DP already created. However, I keep getting the following message:

DP YES).

DP I created the User IDSIUser with the following command:
DP GRANT ALL ON FECData.* TO IDSIUser@'%' INDENTIFIED BY 'excalibur'
^^
You created user for connection via TCP/IP ('%'), but you tried to
connect via Unix socket ('localhost') - because connecting to localhost is
done via Unix sockets..
DP Can anyone possibly tell me what I have left out or what I am doing wrong,
DP or just point me to some documentation that will help me sort out the
DP problem?
Look at:

DP Thanks for the help.

off-line development tool?

Hello every one... We are going into making the final changes to our production MySQL server. production server configuration is Free BSD PIII dual processor 800 mhz, 750 MB RAM. back_log = 20 DEFAULT back_log = 200 CHANGED flush_time = 1800 sec DEFAULT flush_time = 3600 sec CHANGED key_buffer_size = 16 MB DEFAULT key_buffer_size = 30 MB CHANGED max_allowed_packet = 10MB DEFAULT max_allowed_packet = 20MB CHANGED max_connections = 100 DEFAULT max_connections = 250 CHANGED Apache ,Tomcat, MySQL is running on the same machine.Kindly give us your expert opinion is it wise to run the three servers with the given server hardware configuration on the same machine...? Is it safe to alter the above mentioned server variables...? If safe..what is the syntax to set these parameters on Free BSD shell An example would be more help full. Thanx. Vijay Khanna System Analyst www.spsoftware.com Ph: 09120 - 4006154 INDIA FOR THOSE WHO CAME LATE : Hiya forum.. I have my site powered by MySQL server running on FreeBSD. The site is facing problems when the traffic increases.Database connectivity is through JDBC.My poolman is managing the database connections with 30 connections set, and is growable.People have started getting error when the rush increases... Error : Communication failure : Bad Handshake. Is there a MySQL server running on the port connectivity error. I suspect the max_connection variable which is default set to 100 reaches and the server refuses further connection.We have probed for any unused database connections hold by the Java.But we have religiously returned the connection back to the poolmanager after its used... I am running my development MySQL server on windows NT. Having gone thru the MySQL manual..for performance tuning the server,we came across many variables which can affect the server performance. So i issue the following commands: c:\ cd mysql\bin start the serverc:\mysqld set the variablec:\mysqld -O back_log=200 --help Looks like it updates the server..but when i see it thru the WinMySQLAdmin ,after restarting the server again ,it does not reflect there and displays the default settings. We have a production server runningCan any experienced people guide me how to update this server variable onto my remote server. Thanx.

Couple of Performance tweaking questions.
hi everyone, I've got a mysql server, a quad xeon 700MHz, with 8 gigs of ram, and a raid 50 disk array running as two 50 GB partitions, shared over 8 15,000 RPM disks, on a hardware raid card, with 128Mb Cache. Running RedHat Linux 7.2, with Ext3 FS, and Kernel 2.4.9-21 Enterprise (SMP) I'm trying to tweak out the performance to the maximum usage of this hardware, and I found the following on the docs: This can be done by adding renice -20 $$ command to safe_mysqld. In our testing on a 4-CPU machine, increasing the priority gave 60% increase in throughput with 400 clients. So I added the renice -20 $$ line to safe_mysqld, and I get the following: (tailing the .err log while running safe_mysqld.

Naming a Provider?
Guys, I'm very new to ODBC, so please bear with, okay?

That statement succeeds in opening that mdb (Access) file for further manipulation. I have no idea where they came up with the information that the way you connect with an access database is to use the incantation Microsoft.Jet.OLEDB.4.0. Likewise, I have no idea what comparable magic string would specify a mysql database. 1) What string would I substitute into that code sample to connect with a mysql database instead of an access database? 2) What document should I have been looking at to discover that for myself?

Signal 4 crashes on some x86 Linux machines
Simon and others: Signal 4 means illegal instruction. This happens when the binary users an instruction that is not compatible with your architecture. In theory, this should not happen - to our knowledge, the binary should work just fine on any architecture. However, if it does not, this means we've messed up, and we would like to know where. Anybody who gets signal 4 - please send me the output of cat /proc/cpuinfo and the stack trace.

Alter Table with InnoDB table type having foreign keys
A humble suggestion for the development team I went through and looked at some of the postings regarding using ALTER TABLE with InnoDB tables and the resulting loss of foreign key constrains. I was disappointed to learn about the need to use the create/drop workaround. The main reason I considered using InnoDB tables was to have a MySQL database that could ensure referential integrity. The thought that a command (ALTER TABLE) would silently break RI makes me very uneasy, and lessens the value I see in using MySQL. (OK, MySQL-Max) I understand that in MySQL the alter table command may in fact transparently do a create, drop and/or rename of tables, regardless of table type. But it still makes no sense to me that the ALTER TABLE command does not maintain foreign key constraints for the InnoDB table type. If MySQL does an internal create and drop to execute an alter table statement, and the table in question has a primary key, isn't the primary key transparently recreated? Isn't the same true for all other constraints?? (If not, please let me know!!) Why then shouldn't MySQL recreate the foreign key constraints too? If the reason is because the file is temporarily copied to a non InnoDB table type, couldn't the foreign key information be held temporarily in another object of some sort and applied after conversion back to InnoDB? Of course, I understand that there are priorities in development, and one should not expect to have all the bells an whistles the right away. That said, I shudder every time I open myPHPAdmin and see how easy it would be for any developer or administrator to break foreign key constraints. Therefore, I was hoping that you could consider adding foreign key support to the ALTER TABLE command, or at least consider adding an option such as innodb_fail_alter_table_with_fk that would warn or fail the alter table statement if the table type was InnoDB and foreign keys were going to be dropped. If this latter option was implemented, it would prevent RI from being quietly lost.

[re-post] MySQL on OpenBSD/sparc64?
[I didn't get a response from openbsd-sparc, so I'm trying here. Any help would be appreciated!] I'm trying to get a MySQL server running under a recent OpenBSD 3.0 snapshot on an Ultra 5, but I'm not having much luck. I tried installing the binary mysql-server package (from 3.0/packages/sparc64/), but it looks like the mysqld in that package is linked against libwrap1.2, whereas 2.0 is included in that snapshot (and 3.0 itself, too?).

Doc Bug: Comments in Documentation
Um, hello? I wasn't trying to turn this into a general bitch session on the manual, and I really don't think that's appropriate. Worse, it obscures and devalues the value of the bug report. I'm just trying to draw attention to a possible software malfunction in the commentary section of the online docs. If you are a tech writer or other employee with mysql.com, please skip the following bracketed paragraphs, they're for others: [[ Please, if you wish to argue about the use of WHERE or case-sensitive searches, do it on some other Subject line, okay? The focus here is specifically on the COMMENTS in the ON-LINE DOCUMENTATION of MYSQL. Those COMMENTS are usually totally irrelevant to the topic being discussed, which makes them USELESS. ]] I will offer an example: Looking for commentary and useful tips on INSERT...SELECT syntax: http://www.mysql.com/doc/I/N/INSERT_SELECT.html What I find begins thus: yval : Note that the input to INET_NTOA, and the output from INET_ATON are in host byte order. Michael Babcock [EMAIL PROTECTED]: As opposed to left.id = right.id, a LEFT join means that all of the left table's IDs are displayed, and only those rows in the right table with the same IDs are joined in. Vice versa for a RIGHT join. Ari Ukkonen [EMAIL PROTECTED]: I think Boolean or logical type is badly needed in Mysql. You can use an Enum and IS NOT NULL/IS NULL in your statements to simulate this to test for the existence or absence of NULL values but this is not an elegant solution. Daniel Scherly [EMAIL PROTECTED]: Example how to use the DATE_FORMAT function to reformat a DATETIME (-MM-DD hh:mm:ss) column and output the newly formated date with PHP: . . . etc., etc. All valuable and appropriate comments, no doubt.

Re: Query Help
Hi Pinkesh, I've got item table as follwoing: itemno|item_name 1 item one 2 item two 3 item three 4 item four 2 item two 3 item three I want to right a query so I get three rows of each item I specify in WHERE for example SELECT itemname from item WHERE itemno IN (1,2,3); Results should return first three rows of each itemno How do I write such query? Your question is slightly ambiguous, but I assume that you want a resultset containing a maximum of three rows WHERE itemno = 1, a maximum of three rows WHERE itemno = 2, and a maximum of three rows WHERE itemno = 3. In which case the answer is: I don't think you can. Unfortunately the (above) query realises the entire sample tbl excepting the single row itemno=4 and item_name=item four, and there are not more than three rows which share any particularly itemno value. (so in abstracting your real problem, you have left no 'hints' for us to be able to offer more than a clinical observation!?) RTFM 6.4.1 SELECT Syntax [LIMIT [offset,] rows] The LIMIT clause allows the control of output to be limited to a range of row numbers out of the complete resultset table. Thus you could limit to nine rows (for example), but there's no guarantee that the resultset would contain an equal number of 1s, 2s, and 3s (assuming that they are available in the original table). At this time, there is no facility to combine (say) the GROUP BY and LIMIT clauses - which might be the answer you seek. Beyond that, what you appear to be asking is not part of the relational model/the design of SQL. Your only other approach would be to post-process the resultset using a scripting/programming language/application.

Re: can i use mysql functions to sort an alpha-numeric description alphabetically?
Hi Nicole, Perhaps it's me, but I'm having trouble following you - as I did with the question I've just finished responding to... I have looked at the online documentation and the mysql books that I have but can find no answer. I have a field that looks like this: (8+2) Landscape I take it that this is the data value stored in the field. What does the schema look like? I want to sort on the alphabetic characters. My mysql query does an order by this field and that returns a numeric order (which for me is not terribly useful.) What do you mean by numeric order? If there was another row containing: (72+18) Landscape Then it would likely appear before the row you mentioned - and not in a numeric sequence at all. Do you mean that you want the parentheses, the digits, the plus sign, AND the space character ignored for the purposes od the sequence, and thereafter that the values should be treated as alpha? Is there any possibility of numerics appearing after the first alpha character? Would that matter or would they have to be ignored as well? So - is there a function or way I can sort this array alphabetically rather than numerically? Yes there are various ways and means, right up to the 'expensive' regular expression function. I think we can solve this one quickly enough - given a good understanding so we don't end up chasing red herrings! Please post the query you are using currently, together with a few rows of output. Then highlight the problem by showing the sequence that you would prefer to see.

Re: can i use mysql functions to sort an alpha-numeric description alphabetically?
Sorry Dan, I had actually replied to Steve who had asked the same question but I forgot to reply to the list with this: here is the query: select catval,catdescr from embiteccat where catzid=$zid and catlid=$lid and catunder=$cat order by catdescr; Here is a some data: 36,1,1,,0,0,2(12+1) Long,,,0,0,prodsku,,6,:6:36:,0,0,1,10 38,1,1,,0,0,24+1 Landscape,,,0,0,prodsku,,6,:6:38:,0,0,1,10 41,1,1,,0,0,6 Portrait,,,0,0,prodsku,,6,:6:41:,0,0,1,10 43,1,1,,0,0,24+1 Long,,,0,0,prodsku,,6,:6:43:,0,0,1,10 44,1,1,,0,0,2(24+1) X-Long,,,0,0,prodsku,,6,:6:44:,0,0,1,10 where catdesc is the 7th field (ie, 2(12+1) Long etc. So far all I can think of is that I have to load it into an array, sort the array with some php function or grep and then spit it out... So - yes you are correct - I want everything before the alphabetic characters, (number, parenthesis, + sign) to be ignored and then to sort by the alpha.

C API, MySql ver 3.23.49 and Apache ver 1.3.23
I've got this problem that now since I updated mysql to ver 3.23.49 and recompiled some of my working cgi scripts Apache is complaining about a server error. Premature end of header scripts. If I use the cgi that I compiled before the upgrade everything is fine. It's the exact same code. I've narrowed it down to the function mysql_real_connect(). I can use mysql_init() to inizalize the mysql variable and mysql_options() and the cgi script runs without crashing on the apache server. Of course the script isn't doing what I want it to because I have to comment everything out because I can't make a connection to the database. everything works great when I run it in debug mode giving the cgi all the env variables but not running the script through the server. The html code that is produced can be loaded into a page and looks and works fine. I've tried installing 3.23.46 which was the version of mysql that I had before over top of ver 49 and recompiled the cgi script but that didn't fix anything. Does anyone have any answers as to why this happened. Does anyone know how to rip all of mysql out and start from scratch instead of reloading the os. Any suggestions please. :) Thanks. - 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: off-line development tool?
If I rember well MySQLdump is a utility. I can run that at my local machine, but how to do the reverse thing at the remote machine. I can't run much more than HTML and PHP scripts there. Is there a tool that can convert the MySQLdump export file into something that looks like a PHP script and that I could unleash a CREATE command on? Thanks, Marco From: Eric Mayers [EMAIL PROTECTED] To: Marco Bleeker [EMAIL PROTECTED], [EMAIL PROTECTED] Subject: RE: off-line development tool? Date: Fri, 22 Feb 2002 18:27:23 -0800 I suggest you install a MySQL Database on a local machine and do development there. When you want to push this stuff to the remote machine use mysqldump to pull the contents out of the local database. I don't think it would be appropriate for this but you might consider database replication if you want it to be a more automatic process. Eric Mayers Software Engineer I Captus Networks -Original Message- From: Marco Bleeker [mailto:[EMAIL PROTECTED]] Sent: Friday, February 22, 2002 5:59 PM To: [EMAIL PROTECTED] Subject: off-line development tool? Hello, I am a beginning MySQL and PHP user. I will run a MySQL database on a remote hosting server, and I have only limited access to the database at that server. I want to populate my database off-line at my home machine, and then upload the whole thing (100s of lengthy entries) to the server. But I don't have direct access there. So I suppose I'll have to do something like exporting my data to a text file, upload the text file to the root of my domain at the server and re-create the database from there. I don't think I can run any tool on the server; I work with .php files there. So my question is: how would people normally go about this task. Would I need to write a script for in- and export of data, or would there perhaps be a handy tool that takes this out of my hands?

Re: can i use mysql functions to sort an alpha-numeric description alphabetically?
Nicole, RTFM: 6.3 Functions for Use in SELECT and WHERE Clauses in particular the String Functions If the first space (in every row) can be taken as the 'marker' of what to remove (including the space itself), then take a look at the following: SELECT catval, RIGHT( strcatdescr, POSITION( ' ' IN strcatdescr ) + 1 ) AS cd FROM embiteccat WHERE catzid=$zid AND catlid=$lid AND catunder=$cat ORDER BY cd; If however there may be more than one space prior to the commencement of the alpha data, then can we search for the last space (ie the first from the right-hand end of the field)? In which case substitute: SUBSTRING_INDEX( strcatdescr, ' ', -1 ) AS cd It's kind of fun to play games like this, but it isn't very 'relational'. Both of the assumptions (above) are not 'good form'. Even if one is acceptable to you, and of course 'in spades' if neither is, should be the consideration of adding another column to the table for sequencing purposes. How are we doing? =dn (David) Sorry Dan, I had actually replied to Steve who had asked the same question but I forgot to reply to the list with this: here is the query: select catval,catdescr from embiteccat where catzid=$zid and catlid=$lid and catunder=$cat order by catdescr; Here is a some data: 36,1,1,,0,0,2(12+1) Long,,,0,0,prodsku,,6,:6:36:,0,0,1,10 38,1,1,,0,0,24+1 Landscape,,,0,0,prodsku,,6,:6:38:,0,0,1,10 41,1,1,,0,0,6 Portrait,,,0,0,prodsku,,6,:6:41:,0,0,1,10 43,1,1,,0,0,24+1 Long,,,0,0,prodsku,,6,:6:43:,0,0,1,10 44,1,1,,0,0,2(24+1) X-Long,,,0,0,prodsku,,6,:6:44:,0,0,1,10 where catdesc is the 7th field (ie, 2(12+1) Long etc. So far all I can think of is that I have to load it into an array, sort the array with some php function or grep and then spit it out... So - yes you are correct - I want everything before the alphabetic characters, (number, parenthesis, + sign) to be ignored and then to sort by the alpha.

Mysql dies with Signal 11
Hi, I seem to be getting intermittant crashes of mysql. The error log prints the following, mysqld got signal 11; This could be because you hit a bug. It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware. We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail. key_buffer_size=268431360 record_buffer=1044480 sort_buffer=1048568 max_used_connections=5 max_connections=100 threads_connected=5 It is possible that mysqld could use up to key_buffer_size + (record_buffer + sort_buffer)*max_connections = 466539 K bytes of memory Hope that's ok; if not, decrease some variables in the equation. 020223 13:00:01 mysqld restarted InnoDB: Database was not shut down normally. InnoDB: Starting recovery from log files... InnoDB: Starting log scan based on checkpoint at InnoDB: log sequence number 82 1555315003 etc... Can some please suggest what steps I can take to discovering what is wrong. I have attached server info and gdb output to bottom of email. This is a very active server processing 150 apache hits a second. A seperate looped process takes cgi data inserted into an IPC MSGQ and sticks it in the db and another seperate looped process takes data from this db and dumps to a db on a remote machine.
