how to create SQL procedure which contains compile time errors?

Question

I am writing a one time SQL procedure which will add an identity column to a table, then set the primary key of the table to that new identity column. But I cannot compile the SQL procedure because the CREATE PROCEDURE statement returns a compile error.

How to tell SQL to create the procedure despite the compile error?

CREATE or replace PROCEDURE TESTSQL(                                
 )
