Question

So I was trying to rename a column in my table from Conversion_Fee_PerShare to just Conversion Fee.

I looked up online and found the syntax be:

sp_RENAME 'TableName.[OldColumnName]', '[NewColumnName]', 'COLUMN'

I wrote my query as:

sp_RENAME 'dbo.AllocationDetails.[Conversion_Fee_Per_Share]' , '[Conversion_Fee]', 'COLUMN'

The column name has now become [Conversion_Fee] instead of Conversion_Fee

Now if am trying to rename again like this:

sp_RENAME 'dbo.AllocationDetails.[Conversion_Fee]' , 'Conversion_Fee', 'COLUMN'

It gives me an error saying:

Msg 15248, Level 11, State 1,
Procedure sp_rename, Line 213 Either
the parameter @objname is ambiguous or
the claimed @objtype (COLUMN) is
wrong.

I tried to Alter Table Drop Column AllocationDetails.[Conversion_Fee] it didn’t work that way either.

Whats the right syntax?

Answer 1

Never mind I found out:

ALTER TABLE dbo.AllocationDetails
DROP COLUMN [[Conversion_Fee]]]

OR

sp_RENAME 'dbo.AllocationDetails.[[Conversion_Fee]]]' , 'Conversion_Fee', 'COLUMN'

these will work fine. 🙂

Using Double Quotes:

exec sp_rename 'dbo.AllocationDetails."[Conversion_Fee]"' , 'Conversion_Fee', 'COLUMN' 

will also work.
