Restore Database

What is the fastest and easiest way to restore a database from a recent backup?

BACKGROUND:

My host says that, at least, one of my online message board tables is corrupted and beyond fixing.

So, he recommends that I restore the database, from a trusted backup.

Problem is that, I created the online database via HeidiSQL, years ago, and now I forget how it's done.

So, please point me in the right direction!

Incidentally, when I try to access my message board, I get the following error message:




phpBB : Critical Error

Error creating new session

I guess this backup is a SQL file? If so, just load it into Heidi's query editor and press F9.

To create a backup, just click Export > Export database as SQL.

This doesn't seem to work.

I have a large database (29 Mb mysql dump file) that I need to restore.

HeidiSQL loads the file into memory (after warning that it will use a lot of memory).

F9 does nothing other than generating the following message - "/* 0 rows affected, 0 rows found. Duration for 0 queries: 0.000 sec. */".

This thread is two years old and talks about loading a dump into the editor. If you have any problem loading dumps into memory, please open a new thread and provide some information. Don't assume the feature is just broken because it isn't.
