ALTER TABLE statement error while rebuilding schema

I am running a product that is rebuilding several tables. On one table, after re-creating a table (afm_groups) with a new primary key constraint, I run the following line:
ALTER TABLE afm_flds ADD CONSTRAINT afm_flds_edit_group
FOREIGN KEY (edit_group) REFERENCES afm_groups(group_name)
go
And get the error:
ALTER TABLE statement conflicted with COLUMN FOREIGN KEY constraint 'afm_flds_edit_group'.
The conflict occurred in database 'Hq', table 'afm_groups', column 'group_name'
There is no foreign key constraint built like this with this statement is executed. Any ideas?
This means that you have data in the edit_group column that doesn't have a
match in the afm_groups table.
(A foreign key's value must exist in the parent table.)
To identify the rows that are violating the foreign key:
SELECT * FROM afm_flds WHERE edit_group NOT IN (SELECT group_name FROM
afm_groups)

You were right. I created an invalid data condition somehow.

Alter column name from SQL?

How can you rename a column in a table (from c# code, preferrably from a SQL script command) without deleting the column and re-creating it with a new name?

Hello,

SQL Server contains a system stored procedure called SP_RENAME which can be used to rename user created object (tables, column, sp's, ...)

For more information, look at the BOL documentation on the subject http://msdn2.microsoft.com/en-us/library/ms188351.aspx (this is the 2005 version, but the system stored procedure also exist in previous version of SQL server)

Hope this helps,

|||Unfortunately this is not implemented in SQL Everywhere - you can only access the renaming APIs via OLE DB. You can always write a wrapper for .NET as I did.|||Guess I reacted to hasty. Thanks for the correction.|||

As of now we don't have direct method (e.g. SP support) for renaming column in SQL Server Everywhere Edition.

Thanks
Sachin
