Sql Server系列：SQL语句查询数据库中表、视图、存储过程等组成

1. 查看用户表

select name from sys.tables

select name from sys.objects where type='U'

select name from sysobjects where xtype='U'

　　其中type或xtype值：U = 用户表 S = 系统表 V = 视图 FN = 标量函数 TF = 表函数 P = 存储过程  TR = 触发器

　　D = 默认值或 DEFAULT 约束 PK = PRIMARY KEY 约束 F = FOREIGN KEY 约束 UQ = UNIQUE 约束

SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES

2. 查看视图

SELECT * FROM INFORMATION_SCHEMA.VIEWS

3. 查看表/视图字段

SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'Product' 

-- 视图VProduct
SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'VProduct' 

select name from syscolumns where id = object_id('Product')

SELECT COLUMN_NAME,DATA_TYPE FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'Product'
