我们有时候会需要查询数据库中包含某字段的所有的表，去进行update，这时就可以用下面的SQL来实现：
select object_name(id) objName,Name as colName
from syscolumns
where (name like'%此次写需要查询的字段名称%')
and id in(select id from sysobjects where xtype='u')
order by objname
;
当然也可以使用游标，把查询出来的Table串接起来，如下：
DECLARE @COLNAMELIKE NVARCHAR()
DECLARE @OBJNAME NVARCHAR()
DECLARE @COLNAME NVARCHAR()
DECLARE @VALUE NVARCHAR()
DECLARE @SQL NVARCHAR(MAX) SET @COLNAMELIKE='%POLICYNUMBER%'
SET @VALUE='MSH-CCIC-GEP-Plan1-13530' DECLARE CUR CURSOR FOR
select object_name(id) objName,Name as colName from syscolumns
where (name like @COLNAMELIKE)
and id in(select id from sysobjects where xtype='u')
order by objname OPEN CUR
FETCH NEXT FROM CUR INTO @OBJNAME,@COLNAME
WHILE @@fetch_status =
BEGIN
SET @SQL=' SELECT * FROM + ' @OBJNAME + ' WHERE ' + @COLNAME + '=''' + @VALUE + ''' '
exec @SQL
FETCH NEXT FROM CUR INTO @OBJNAME,@COLNAME
END
CLOSE CUR
DEALLOCATE CUR
