How can I solve "Either the parameter @objname is ambiguous or the claimed @objtype (COLUMN) is wrong."?

Nuts. I hit this same error weeks ago, and after a lot of wasted time figured out how to make it work--but I've since forgotten it. (Not much help, other than to say yes, it can be done.)

Have you tried different combinations of brackets, or of with and without brackest? e.g.

EXEC sp_rename 'ENG_TEst.ENG_Test_A/C_TYPE', 'ENG_Test_AC_TYPE', 'COLUMN';
EXEC sp_rename '[ENG_TEst].[ENG_Test_A/C_TYPE]', 'ENG_Test_AC_TYPE', 'COLUMN';
EXEC sp_rename '[ENG_TEst].[ENG_Test_A/C_TYPE]', '[ENG_Test_AC_TYPE]', 'COLUMN';
EXEC sp_rename '[ENG_TEst].ENG_Test_A/C_TYPE', 'ENG_Test_AC_TYPE', 'COLUMN';

If all else fails, there's always

  • Create new table (as "xENG_TEst") with proper names
  • Copy data over from old table
  • Drop old table
  • Rename new table to final name

This works

EXEC sp_rename 
@objname = 'ENG_TEst."[ENG_Test_A/C_TYPE]"', 
@newname = 'ENG_Test_A/C_TYPE', 
@objtype = 'COLUMN'

Are you running the query in the correct database? i.e.,

Use MyDatabase;
GO
EXEC sp_rename 'ENG_TEst.[ENG_Test_A/C_TYPE]', 'ENG_Test_AC_TYPE', 'COLUMN';
GO
