SQL SERVER获取信息的方法

obj.name tablename, schem.name schemname, CAST ( CASE WHEN (SELECT COUNT(1) FROM sys.indexes WHERE object_id= obj.OBJECT_ID AND is_primary_key=1) >=1 THEN 1 ELSE 0 END AS BIT) HasPrimaryKey from sys.objects obj inner join dbo.sysindexes idx on obj.object_id=idx.id and idx.indid<=1 INNER JOIN sys.schemas schem ON obj.schema_id=schem.schema_id where type=‘U‘ and obj.name =‘表名‘ order by obj.name

 

获取表的字段名及类型

1、方法一

SELECT * FROM INFORMATION_SCHEMA.columns WHERE TABLE_NAME=‘表名‘ 

2、方法二

select a.name tablename, b.name colName, c.name colType ,c.length colLength

from sysobjects a inner join syscolumns b
on a.id=b.id and a.xtype=‘U‘
inner join systypes c
on b.xtype=c.xusertype

where a.name=‘表名‘

 规律：

表信息存储在：sys.objects

架构信息在：sys.schemas

索引信息在：sys.indexes

列信息在：sys.columns

这四个都是视图。
