CREATE TRIGGER必须是批处理中的第一个语句

Question

我有以下触发器:

 CREATE Trigger enroll_limit on Enrollments
 Instead of Insert
 As
 Declare @Count int
 Declare @Capacity int
 Select @Count = COUNT(*) From Enrollments
 Select @Capacity = Capacity From CourseSections
 If @Count < @Capacity
 Begin 
      Insert Into Enrollments Select * From Inserted
 End
 GO

我收到一条错误消息说:

'CREATE TRIGGER'必须是查询批处理中的第一个语句.

Answer 1

错误消息"'CREATE TRIGGER'必须是查询批处理中的第一个语句." 通常在前面的一组(批)语句没有终止时发生GO

所以,我建议GO在前一批的语句末尾添加一个add .
