--- Username size limitations
hey dudes, i'd really need some insight on this. Does anyone have any idea about this ? TIA heya, I have a quick and painless (i hope :) )question.. Do you know how the username length is limited under MySQL. There is no mention of this in the manual or books. I figured the username length was dynamically limited by the length of the User field in the mysql.user table. But i have users with Username longer than 32 characters and those get an Access denied error. And, say the username is supercalifragilistixexpicalidocious (36 characters) it tells that user [EMAIL PROTECTED] can't login. I have then changed the user field length in the mysql.user table to 128. But still, can't login. I've looked into the code. First thing, the username is cropped at 32 characters in the error message itself. Indeed, in errmsg.txt, the access denied error format string is : Access denied for user: '[EMAIL PROTECTED]' to database '%-.64s' I haven't tried recompiling with a longer username string conversion, but if you guys tell me MySQL is not cropping the username before matching it against the privilege table, i will to be sure. I have looked at the user authentication code and haven't found anything that would seem to crop at 32 characters even though i have found a constant name USERNAME_LENGTH fixed at 16 characters..which would have been coherent if it was fixed at 32 .. so i don'treally know what to believe. Can anyone tell me exactly what happens ? Is mysql really hard limiting the username to 32 characters ? I don't think i have a hostname issue since from a same machine, another login with the exact same user privilege except the username length works.. If mysql crops the username, is there a patch against it ? If someone can point me where in the code this is handled i could do the patch myself, just need a hint as to where to find the stuff :) I have merely overlooked the code to find obvious proff mysql was doing this but didn't. any insight would be greatly appreciated.

But that's not very accurate, for example i could do an alter table and make the User field be 80 characters. It still wouldn't change the fact that Mysql Hard limits in the code the Login size to 16 which in my mind seems pretty harsh. I've patched it roughly for my needs by defining USERNAME_LENGTH to 80 in include/mysql_com.h but it doesn't really fit me cause next time i'll upgrade mysql, I'll have to patch it again. Don't you guys see the disadvantage of hard limiting so badly the Daemon ? Is there any plan to change this in the future ? Just my 2 cents. -- Chand Speed is good but stability is god.

The no longer, however, is a function of later Linux kernels and filesystems. Linux 2.2 kernels with the ext2 filesystem (probably still the most common setup) have a 2GB file size limitation, which is the cause of the MySQL table size limitation. MyISAM tables, at least on 3.23, have a 4GB limitation unless you specifially configure it otherwise, even if the OS allows larger files. Given all of the possible combinations, if you're going to be pushing the limits of table sizes, it's best to simply test and find out what your particular config will allow you do to. james montebello - 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?

Table size limitations: Error Handling and Raid 0
My question is two-fold, first regarding error handing of table size limitations, and secondly performance and other implications of raid striping. I'm building a system with an integrated MySQL database and there is a potential for filling up tables to the maximum file size for the OS I'm using (linux 2.2.x kernel, ext2 fs, 2gb max file size). I'd like to provide users with a graceful error-handling mechanism, essentially telling them: The database is full. You must remove stuff before you can add more. Along with that, a % used number would be nice. Is there a method (through a mysql query) of determining how much space the database is taking up? It seems like the alternative is looking directly at the file system's record. Secondly, to get past the 2gb limit I'm considering using Raid Striping on a single partition. I'm curious if people have done this and what the performance implications are (how much worse is 2, 3, 10, 20 files than one file), and does doing this successfully avoid the 2gb limit (or is there some other limiting factor?) What is the next limiting factor beyond the file system's 2gb limit given unlimited storage?

Table size limitations...
I have a table that holds a lot of information. I tried to INSERT something into it, and received... DBD::mysql::st execute failed: The table 'fancy_big_table' is full at ./tom_to_mutt.pl line 156. The table is 4G is size. The table's Max_data_length = 4294967295 (4G) I'm running the MySQL server on a FreeBSD system, and this is not a file system limitation. I am using MyISAM tables. So, I'm not sure what to do. I could easily double the size of that table in the next few months. After reading the CREATE TABLE page in the manual, I thought that increasing the AVG_ROW_LENGTH would help since it says that... MySQL uses the product of max_rows * avg_row_length to decide how big the resulting table will be I ran ALTER TABLE fancy_big_table AVG_ROW_LENGTH = 9482; and after a long time, it finished without error, but inspecting the Avg_row_length and the Max_data_length afterwards showed no change. Maybe this is a red herring, and totally down the wrong path. I'm not sure. So, if one of you could help me figure out how to cram more crap into my table, I'd be awefully appreciative.

RE: Table size limitations...
I'm not an SQL expert but if FreeBSD supports 4GB files than you should check your MAX_DATA_LENGTH properties on the table you're using. You can do this by running SHOW TABLE STATUS on the table. I believe you can use ALTER (or on create table statements) to change this value.
