RE: Suspected Bug
I think there are a couple of bugs here: First, per the documentation, 6.1.3 Case Sensitivity in Names (http://www.mysql.com/doc/N/a/Name_case_sensitivity.html), the Windows mysqld is starting with -O lower_case_table_names=1 by default, so all filenames should be converted to lowercase automatically. The create and insert statements are performing as they should. But the RENAME is not, RENAME will create a table in upper case. I believe the first bug is that the RENAME is not respecting the lower_case_table_names option. Second, the error, 7 - Error on rename '.\db\X1.MY1' to '.\db\X2.MYI' (Errcode: 13) is with the index file. After playing around a bit, the following SQL does work: CREATE TABLE X1 (x smallint); insert into X1 values(5); FLUSH TABLES; RENAME TABLE X1 TO X2; My guess is that RENAME is not closing the index file, but FLUSH takes care of that. And the workaround as stated before is to just use lowercase table names. BTW, the following works fine: CREATE TABLE X1 (x smallint); insert into X1 values(5); RENAME TABLE x1 TO x2; -- note names are lowercase --Fred -Original Message- From: DL Neil [mailto:[EMAIL PROTECTED]] Sent: Friday, February 15, 2002 7:20 AM To: SubbaReddy M; [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: Suspected Bug Once tables are CREATEd, the name is listed in SHOW tables using lower case characters, regardless of the case used in the CREATE command. Using upper case table names in RENAME results in the error. Workaround: Using lower case equivalent table names works, regardless of the case used in the CREATE command. Windows does not differentiate between X1 and x1 as table/filenames. *nix does. Perhaps CREATE has been Window-ised but RENAME has not (yet).
