如何在查询中显示包含结果集的表名？

Question

我有一个使用过的查询如下：

SELECT LTRIM(RTRIM(ClaimsAdminName)) + ' | ' + LTRIM(RTRIM(ClaimsAdminID)) AS Clientname
FROM tblClaimsAdmin
WHERE (ClaimsAdminName LIKE @Prefix)
UNION
SELECT LTRIM(RTRIM(EmployerFName + ' ' + EmployerLName)) + ' | ' + LTRIM(RTRIM(EmployerID)) AS Clientname
FROM tblEmployer
WHERE (EmployerFName LIKE @Prefix)

如果输入's％'，则返回结果：

s | 8 Sumit Singh | 16

现在有什么方法可以让我返回带有结果集的tablename。就像值来自哪个表一样。

我希望我的查询清楚。

请帮忙！
