SQL Server 2008基于子字符串的审计触发器

Question

我想根据列创建触发器，但仅限于以_ess结尾的那些记录。我如何设置审计触发器来执行此操作？

这是当前的触发器，但它只是检查用户名的所有更改，而我只是希望它检查用户名更新为或来自以_ess结尾的用户名。

只需补充一点：

INSERT INTO AuditedRows (OperationNum, RowPK) 
SELECT @OperationNum, ISNULL(CAST(INSERTED.ID as nvarchar),CAST(DELETED.ID as nvarchar)) 
FROM INSERTED FULL OUTER JOIN DELETED ON INSERTED.ID=DELETED.ID 
-- Restrict it to only those where the username is changing from or to %_ess 
WHERE (deleted.username like '%_ess' or inserted.username like '%_ess') 

INSERT INTO AuditedRowsColumns (OperationNum, RowPK, ColumnName, ColumnAudReg, OldValue, NewValue) 
SELECT @OperationNum, ISNULL(CAST(INSERTED.ID as nvarchar),CAST(DELETED.ID as nvarchar)), 'USERNAME','A', CONVERT(VARCHAR(3500),DELETED.USERNAME), CONVERT(VARCHAR(3500),INSERTED.USERNAME) 
FROM INSERTED FULL OUTER JOIN DELETED ON INSERTED.ID=DELETED.ID 
-- Restrict it to only those where the username is changing from or to %_ess 
WHERE (deleted.username like '%_ess' or inserted.username like '%_ess')
