      Description

      For Oracle compatibility, we'll allow NOT NULL constraint for routine variables in sql_mode=ORACLE

      DECLARE
        a NOT NULL INT;
      BEGIN
        a:=1;
        a:=NULL; -- This should return an error
      END;
      

      and in the default sql_mode:

      BEGIN
        DECLARE a NOT NULL INT;
        SET a=1;
        SET a=NULL; -- This should return an error
      END;
