我想基于列创建触发器，但仅适用于以_ess. 如何设置审核触发器来执行此操作？

这是当前触发器，但它只检查用户名的所有更改，而我只希望它检查用户名何时更新为或从以 _ess 结尾的用户名。

只需添加以下内容：

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')
