网上的问题：
参考这篇《函数PARSENAME使用和截取字符串》https://www.cnblogs.com/insus/p/10958452.html 的方法：
DECLARE @str VARCHAR(1000)=‘||MO21|TMT-0080|1|10‘ SET @str = REPLACE(STUFF(@str,1,2,‘‘),‘|‘,‘.‘) SELECT PARSENAME(@str,3) --PARSENAME(@str,4) AS [TABLE_CATALOG], --PARSENAME(@str,3) AS [TABLE_SCHEMA], --PARSENAME(@str,2) AS [TABLE_NAME], --PARSENAME(@str,1) AS [COLUMN_NAME] GO
