MySQL Bugs: #7031: Foreign keys always have almost the same name

Bug #7031	Foreign keys always have almost the same name
Submitted:	6 Dec 2004 8:38	Modified:	10 Dec 2004 12:37
Reporter:	Jerome Canler	Email Updates:
Status:	Closed	Impact on me:	None
Category:	MySQL Administrator	Severity:	S3 (Non-critical)
Version:	1.0.16	OS:	Windows (WinXP Pro SP2)
Assigned to:		CPU Architecture:	Any

Description:
Each time I create a foreign key constraint, the table editor asks me the key name; so I type an explicit name. The generated SQL query looks perfect.
However, but when I close the table editor and re-open it, the foreign keys have the name 'contact_ibfk_xx' where xx is a number.Thus the name I gave during the creation is lost.

How to repeat:
Create or modify a table with the table editor.
Specify a column as a foreign key.
Type the key name of your choice. 
Click on 'apply changes'
Close the table editor
Re-open the table editor and display  the 'foreign keys' tab.

Suggested fix:
?

Hi!

The name of a FOREIGN KEY constraint is really the CONSTRAINT name, not a key (or index) name.

Maybe MySQL Administrator should be modified so that you can also specify the CONSTRAINT name?

Thanks Heikki, but I don't understand why the table editor allows me to give a name to the foreign key (name appearing in the generated SQL query) whereas this data isn't kept by the server (Is this a mySQL bug or a functionality that will be available in the future ?)

Thanks for reporting! It was a bug in the table editor. It is now fixed and will be in the next release of MA and QB.

Thank you for your bug report. This issue has been committed to our
source repository of that product and will be incorporated into the
next release.
