不同库表间(含字段)比较的SQL代码

use accdb1 --为zy旧库,Accdb为液晶版标准库,已知Accdb库比Accdb1库多出表和字段,求多出的表和字段

SELECT accdb.table_name AS accdb_table_name,
accdb.columns_name AS accdb_columns_name,
accdb1.table_name AS accdb1_table_name,
accdb1.columns_name AS accdb1_columns_name
FROM (SELECT Accdb.dbo.sysobjects.name AS table_name,
Accdb.dbo.syscolumns.name AS columns_name
FROM Accdb.dbo.syscolumns INNER JOIN
Accdb.dbo.sysobjects ON
Accdb.dbo.syscolumns.id = Accdb.dbo.sysobjects.id
WHERE (NOT (Accdb.dbo.syscolumns.name LIKE '@%')) AND
(Accdb.dbo.sysobjects.xtype = 'U')) accdb LEFT OUTER JOIN
(SELECT sysobjects.name AS table_name,
syscolumns.name AS columns_name
FROM syscolumns INNER JOIN
sysobjects ON syscolumns.id = sysobjects.id
WHERE (NOT (syscolumns.name LIKE '@%')) AND (sysobjects.xtype = 'U'))
accdb1 ON accdb.columns_name = accdb1.columns_name AND
accdb.table_name = accdb1.table_name
WHERE (accdb1.table_name IS NULL) OR
(accdb1.columns_name IS NULL) order by accdb.table_name,accdb.columns_name
