firebird 将触发器更改为存储过程

Question

如何将触发器更改为存储过程？我有以下代码：

CREATE PROCEDURE PESTADOTRIGGER (
    disparador varchar(40),
    estado integer)
as
declare variable cadena varchar(500);
begin

    if (:estado = 1) then
    begin
        cadena = 'ALTER TRIGGER ' || :disparador ||  ' ACTIVE';
        EXECUTE STATEMENT :CADENA  WITH AUTONOMOUS TRANSACTION;
    END
    ELSE
    begin 
        cadena = 'ALTER TRIGGER ' || :disparador ||  ' INACTIVE';
        EXECUTE STATEMENT :CADENA  WITH AUTONOMOUS TRANSACTION;
    END

end

执行存储过程时显示消息：

unsuccessful metadata update modify trigger failed no peermission for control acess to table

我是运行用SYSDBA用户的程序，但是不行

您应该检查您的数据库用户。触发器可以由创建者、SYSDBA 用户和其他具有超级用户权限的用户更改。

尝试以 SYSDBA 用户身份执行存储过程。
