MySQL Workbench Alter Procedure

Did you get the very, very latest?

The latest stable build (here) is 5.1.19. However, the bug fix has been put in place for 5.2.21 (per here).

The absolute latest version available is 5.2.34, which should have the bug fix. However, that's not the latest stable version; it's just the latest generally available (GA) version. (It's available here, for what it's worth.)

Edit

Since you have the latest version (with the alleged bug fix), I would report this as a new bug.

My only advice... Try to figure out if there is an exact sequence of steps that you can perform to make this happen every time. Then give them all the information you can (including the version number you're using).

MySql Workbench is powerful, but not perfect.

Some time in similar case, I've done the following to resolve the problem:

• create a blank project
• require a model update FROM db source
• then I'll reapply the mod.

Often this happen if you just change a 'comma' [a small thing] in the db without sync it with the model, and then you change another 'comma' in the model. MySql Workbench goes crazy often as db increases in complexity and table number, but I think it's a very good product.
