使用查询访问 SQL 中的列描述 [英] Use a Query to access column description in SQL

问题描述

我正在尝试使用 INFORMATION_SCHEMA 访问列描述属性

I am trying to access the Column description properties using the INFORMATION_SCHEMA

我过去创建了这个查询来获取列名，但我不知道如何获取列的描述

I have created this Query in the past to get the column name but i can not figure out how to get description of the column

SELECT COLUMN_NAME AS Output, ORDINAL_POSITION 
FROM INFORMATION_SCHEMA.COLUMNS 
WHERE  (TABLE_NAME = @Tablename) AND (ORDINAL_POSITION = @Location)

这是描述在字段属性上的位置

This is where the Description is on the field properties

推荐答案

如果描述"是指在设计模式下 SQL Management Studio 中显示的描述"，则是:

If by 'description' you mean 'Description' displayed in SQL Management Studio in design mode, here it is:

    select 
        st.name [Table],
        sc.name [Column],
        sep.value [Description]
    from sys.tables st
    inner join sys.columns sc on st.object_id = sc.object_id
    left join sys.extended_properties sep on st.object_id = sep.major_id
                                         and sc.column_id = sep.minor_id
                                         and sep.name = 'MS_Description'
    where st.name = @TableName
    and sc.name = @ColumnName
