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_nameFROM (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_nameWHERE (accdb1.table_name IS NULL) OR      (accdb1.columns_name IS NULL) order by accdb.table_name,accdb.columns_name
