Select TABLE_NAME FROM 数据库名称.INFORMATION_SCHEMA.TABLES Where TABLE_TYPE='BASE TABLE' 执行之后，就可以看到数据库中所有属于自己建的表的名称
2、查询SQL中所有表及列：
Select dbo.sysobjects.name as Table_name, dbo.syscolumns.name AS Column_name FROM dbo.syscolumns INNER JOIN dbo.sysobjects ON dbo.syscolumns.id = dbo.sysobjects.id Where (dbo.sysobjects.xtype = 'u') AND (NOT (dbo.sysobjects.name LIKE 'dtproperties'))
