遍历数据库，删除包含指定列的表的行数据-

IF OBJECT_ID (‘dbo.spDeleteRowDate_In_DB‘) IS NOT NULL
    DROP PROCEDURE dbo.spDeleteRowDate_In_DB
    go
create proc spDeleteRowDate_In_DB
( 
    @compid int                 --公司ID
)
AS
DECLARE @tableName varchar(50) 
DECLARE My_Cursor CURSOR --定义游标
FOR (select OBJECT_NAME(id) from syscolumns where id in(
select id from sysobjects where type=‘U‘)
and name=‘compid‘) --查出需要的集合放到游标中
OPEN My_Cursor; --打开游标
FETCH NEXT FROM My_Cursor INTO @tableName; --读取第一行数据(将表名放到@tableName变量中)
WHILE @@FETCH_STATUS = 0
    BEGIN
    declare @sql nvarchar(1000)
      set @sql = ‘ delete from ‘+@tableName+‘ where compid= ‘+Convert(varchar(50),@compid )
        print @sql
        exec (@sql)
        FETCH NEXT FROM My_Cursor INTO @tableName; --读取下一行数据 
    END
CLOSE My_Cursor; --关闭游标
DEALLOCATE My_Cursor; --释放游标
GO
