我有这样的脚本，从理论上讲，该脚本使我可以为数据库中的每个表创建相同的触发器：
DECLARE @insertTriggers VARCHAR(MAX) = '';
SELECT @insertTriggers = @insertTriggers1 + *Some Trigger creation code ending with 'GO'"
FROM INFORMATION_SCHEMA.TABLES
EXEC(@insertTriggers);
当我使用PRINT并将其复制到其他查询时，它可以工作，因为我可以用关键字GO分隔CREATE TRIGGERS。在这里不起作用。我能做什么？我必须为每个触发器分别编写一个代码吗？

根据我的评论，我出于审计目的开发了此SP，但它最初可能不适用于您，但是如果您更改它，我相信它将为您提供帮助。
否则，请更改您对触发器需要执行的操作的问题，然后我将更改答案以为您工作...

您可以使用它作为模板来创建触发器。
DECLARE @TriggerTemplate NVARCHAR(MAX)
DECLARE @TriggerNameTemplate NVARCHAR(250)
DECLARE @Tables TABLE (ID INT IDENTITY, TableName VARCHAR(100))
INSERT @Tables
SELECT TABLE_NAME FROM INFORMATION_SCHEMA.Tables WHERE TABLE_TYPE = 'BASE TABLE'
DECLARE @ID INT, @TableName VARCHAR(100)
DECLARE @SQL NVARCHAR(MAX), @TriggerName NVARCHAR(250)
WHILE EXISTS (SELECT 1 FROM @Tables)
BEGIN
SELECT TOP 1 @ID = ID, @TableName = TableName FROM @Tables
SET @TriggerName = REPLACE(@TriggerNameTemplate,'#TableName#', QUOTENAME(@TableName))
IF EXISTS(SELECT * FROM sys.triggers WHERE name = @TriggerName)
BEGIN
SET @SQL = 'DROP TRIGGER ' + @TriggerName
EXEC (@SQL)
END
SET @SQL = REPLACE(@TriggerTemplate,'#TableName#', QUOTENAME(@TableName))
EXEC(@SQL)
DELETE @Tables WHERE ID = @ID
END
