Question

我试图在Derby数据库中类似Oracle模式以进行测试。该模式还应包括同一个表的2个触发器。

我将它们定义如下：

create trigger myTrigger
    after update on myTable
    referencing old as oldRow new as newRow
    for each row MODE DB2SQL
        delete from otherTable where otherTable.id=newRow.id and newRow.usable is not null and newRow.usable='1' and oldRow.usable='0';

create trigger myTrigger2
    after update on myTable
    referencing old as oldRow new as newRow
    for each row MODE DB2SQL
        update myTable set counter=0 where myTable.id=newRow.id and newRow.usable is not null and newRow.usable='1' and oldRow.usable='0';

当我只定义其中一个时，它工作正常，但是一旦我同时定义了两个，我就会收到这个错误：

有人知道触发器定义有什么问题吗？
