sql根据表名获取字段及对应说明

数据库操作教程 2022-09-23 20:22:51 转载来源: 网络整理/侵权必删

复制代码代码如下:SELECTTableName=OBJECT_NAME(c.object_id),ColumnsName=c

复制代码 代码如下:

SELECT
TableName = OBJECT_NAME(c.object_id),
ColumnsName = c.name,
Description = ex.value,
ColumnType=t.name,
Length=c.max_length
FROM
sys.columns c
LEFT OUTER JOIN
sys.extended_properties ex
ON
ex.major_id = c.object_id
AND ex.minor_id = c.column_id
AND ex.name = 'MS_Description'
left outer join
systypes t
on c.system_type_id=t.xtype
WHERE
OBJECTPROPERTY(c.object_id, 'IsMsShipped')=0
AND OBJECT_NAME(c.object_id) ='tablename'



1.获取所有数据库名:
Select Name FROM Master..SysDatabases orDER BY Name
2.获取所有表名:
Select Name FROM DatabaseName..SysObjects Where XType='U' orDER BY Name
XType='U':表示所有用户表;
XType='S':表示所有系统表;
3.获取所有字段名:
Select Name FROM SysColumns Where id=Object_Id('TableName')
