Renaming a database?

It looks like thereâ€=99s no way to rename a database. Is that true?

=20

I have two reasons for wanting to do this:

=20

- I want to get a current version of a database out of the way so that I =
can load in an older version, without having to pay the penalty of =
reloading the current version.

- I think I have a database that isnâ€=99t being used (donâ€=99t =
ask), and I want to hide it to see if anything blows up.

=20

Suggestions?

=20

Instead of renaming it, revoke permissions to it. If it's being used you
should see some problems in the application due to access denied.

Yes. Silly oversight, although there's probably complexity reasons behind i=
t.

That precludes "rename table db1.blah to db2.blah", I guess - it basically =
copies the whole thing and then kills the old one. Slowwwwww for big tables=
:-)

If you are in a position to shut your server down, you may rename the datab=
ase directory while it's down IF you only use MyISAM tables.

If you have InnoDB tables, you're stuck with dump/reload or rename table.

[JS] According to the documentation, this was implemented at one time but it
caused problems so the feature was removed.

[JS] That's a good suggestion. It takes care of one case, but not the other.

Could you try restoring the other db with another name and changing the
connection string in the app?

Could you try restoring the other db with another name and changing the =
connection string in the app?

[JS] I could, but it would be a nuisance. The app is MS Access, so there =
isnâ€=99t just one string to change.

Fortunately my database only takes about 30 minutes to load, so this =
wasnâ€=99t a huge problem. I just wanted to make sure I =
wasnâ€=99t missing something.

I know. Retarded right? Version 5.1.x and still what would seem the most =
basic of tasks is still impossible.=20

Maybe Oracle can fix what MontyAB and Sun couldn't... that feature alone =
would be well worth the $5.6 Billion dollars spent.

I just had a need to do this last week and was astonished to find it's =
still not implemented after all these... well ever! I unfortunately had =
to dump the database to a .sql file, edit said file, re-dump in, then =
dump in the new database, then run a SQL diff tool to find out what =
schemata and data was different. The whole process delayed me a few =
hours that I didn't budget for. Talk about a hindrance.=20

-----

And before anyone gets all upset with my use of the word "Retarded"...
Read this: http://dev.mysql.com/doc/refman/5.1/en/rename-database.html

And then the definition:

reâ€=A2tardâ€=A2ed

â€=93verb (used with object)
1. to make slow; delay the development or progress of (an action, =
process, etc.); hinder or impede.

â€=93verb (used without object)
2. to be delayed.
