Sql server 查询数据库中包含某字段的所有的表

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(100)
DECLARE @OBJNAME NVARCHAR(100)
DECLARE @COLNAME NVARCHAR(100)
DECLARE @VALUE NVARCHAR(100)
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 = 0 
BEGIN
    SET @SQL=' SELECT * FROM + ' @OBJNAME + ' WHERE ' + @COLNAME + '=''' + @VALUE + ''' '
    exec @SQL
    FETCH NEXT FROM CUR INTO @OBJNAME,@COLNAME
END
CLOSE  CUR
DEALLOCATE CUR
