获取数据表中列的描述值

前面有写过《MS SQL为字段添加说明》http://www.javashuo.com/article/p-qpqosgjd-gq.html

现现在，咱们获取这些字段的描述值。

先来看一句SELECT语句：

 

SELECT * FROM sys.extended_properties
GO

Source Code

 

如上SQL语句，虽然获得描述的值，但咱们不清楚是哪一张表，和哪个字段的说明。

所以，得使用系统另外对象来关联查询：

 

SELECT t.[name] AS [Table_Name],c.[name] AS [Column_Name],e.[value] AS [Column_Description]
FROM sys.tables t
INNER JOIN sys.columns c ON(t.[object_id] = c.[object_id])
LEFT JOIN sys.extended_properties e ON (t.[object_id] = e.[major_id] AND c.[column_id] = e.[minor_id] AND e.[name] = 'MS_Description')

GO
