首页 / 数据库 / SQLServer / sql根据表名获取字段及对应说明

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"）
