How to rename a MS SQL server database table column name after the table creation??
You can rename a column regardless of it is null or contains any data.
We need to use a System stored procedure to rename. Any command with alter keywords won’t work.
EXEC sp_rename ‘tableName.[oldColumnName]‘, ‘newColumnName’, ‘COLUMN’
EXEC sp_rename ‘Ultra_tblPressRelease.[uShowStatus]‘, ‘uShowInA2B’, ‘COLUMN’
The above line will rename the existing column named uShowStatus of table tblPressRelease to uShowInA2B.
There will be no adverse effect of this procedure on your table data.
But you have to update all your SQL Cursors and Stored Procedures with the new column name (if any).
