Question

我有这个触发器，它在回滚时返回错误，错误是“事务在触发器中结束。批处理已经中止。”

create trigger trigger1 on payments
for insert
as
set nocount on ;
begin
    if(select COUNT(*) from customers c , inserted i where c.customer_id = i.customer_id) = 0

        begin
            rollback tran;
            print 'Customer not found'
        end
     else

        print 'ok'

end

根据评论尝试从触发器中提出错误而不是回滚（OR）回滚然后抛出/引发错误并从触发器返回，如下所示

create trigger trigger1 on payments
for insert
as
set nocount on;
begin
    if(select COUNT(*) from customers c join inserted i 
    on c.customer_id = i.customer_id) = 0
        begin
        declare @errmsg VARCHAR(MAX), @sev AS INT, @state AS INT
        SELECT @errmsg = ERROR_MESSAGE(), @sev = ERROR_SEVERITY(), 
        @state = ERROR_STATE()
        print 'Customer not found'
        rollback transaction
        raiserror(@errmsg,@sev,@state);
      return
        end
     else
        print 'ok'
end

回滚时触发错误
