Converting table types
Hello, I was wondering what happens when you change table types. Does MySQL automatically get rid of the old table files? I'm looking into changing out some tables from MyISAM to InnoDB. I'm not tight on space, but I wasn't sure how it handled the conversion, since the storage location changes with this. -- Greg Macek | Senior IT Manager Marketing Resources, Inc.

Converting table types
I don't believe my web host has either InnoDB or BDB installed on their system so I ran some tests here: mysql alter table Development_EventType TYPE=INNODB; Query OK, 3 rows affected (0.00 sec) Records: 3 Duplicates: 0 Warnings: 0 That's the result I get, but when I do a table dump, the type is still showing MyISAM. 1. Is my syntax correct on this? 2. Is there a way to list table types installed in a system? I do have php installed , there, if that helps.

Re: Converting table types
Excellent, thanks much, that solved the problem: mysql SHOW VARIABLES LIKE 'have\_%'; +---+---+ | Variable_name | Value | +---+---+ | have_bdb | NO| | have_gemini | NO| | have_innodb | NO| | have_isam | YES | | have_raid | NO| | have_ssl | NO| +---+---+ 6 rows in set (0.00 sec) mysql Looks to pretty clear like it ain't there.

I do have php installed , there, if that helps. SHOW VARIABLES LIKE 'have\_%' will show many of them. MyISAM doesn't show up in the list; it's always available, from MySQL 3.23 on.
