 Description   

The sp_suid rule is implemented differently in sql_yacc.yy and sql_yacc_ora.yy:

sql_yacc.yy writes directly to Lex:

sp_suid:
 
          SQL_SYM SECURITY_SYM DEFINER_SYM
 
          {
 
            Lex->sp_chistics.suid= SP_IS_SUID;
 
          }
 
        | SQL_SYM SECURITY_SYM INVOKER_SYM
 
          {
 
            Lex->sp_chistics.suid= SP_IS_NOT_SUID;
 
          }
 
         ;

sql_yacc_ora.yy uses Bison stack:

 sp_suid:
 
          SQL_SYM SECURITY_SYM DEFINER_SYM { $$= SP_IS_SUID; }
 
        | SQL_SYM SECURITY_SYM INVOKER_SYM { $$= SP_IS_NOT_SUID; }
 
        ;

In order to unify the two *.yy files easier, we'll port the sql_yacc_ora.yy implementation to sql_yacc.yy as a separate commit.
