Required Privileges

You must have both of the following privileges to rename an external UDF.

  • DROP FUNCTION on the external UDF or its containing database.
  • CREATE FUNCTION on the database that contains the external UDF.

If the function is a row-level security UDF, you must also have the CONSTRAINT DEFINITION privilege to execute RENAME FUNCTION.

Before renaming a row-level security UDF, you must use ALTER CONSTRAINT to drop or replace the UDF in any CONSTRAINT objects that specify the UDF.
