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'))
3、在Sql查询分析器,还有一个简单的查询方法:
EXEC sp_MSforeachtable @command1="sp_spaceused '?'" 执行完之后,就可以看到数据库中所有用户表的信息

select count(*) 总存储过程数 from sysobjects where xtype='p'
D = 默认值或 DEFAULT 约束
F = FOREIGN KEY 约束
