SQL,怎样获取表描述说明，以及字段说明描述，

Posted 2023-04-05

比如，想通过1.查询获取表ORDR 的表描述信息是 【采购订单】
2. 查询获取知道 表中字段 【ORDR.CardCode】 的描述信息是【供应商代码】，【ORDR.ItemCode】的描述信息是【物料代码】

参考技术A SELECT
[Table Name] = i_s.TABLE_NAME,
[Column Name] = i_s.COLUMN_NAME,
[Description] = s.value
FROM
INFORMATION_SCHEMA.COLUMNS i_s
LEFT OUTER JOIN
sysproperties s
ON
s.id = OBJECT_ID(i_s.TABLE_SCHEMA+'.'+i_s.TABLE_NAME)
AND s.smallid = i_s.ORDINAL_POSITION
AND s.name = 'MS_Description'
WHERE
OBJECTPROPERTY(OBJECT_ID(i_s.TABLE_SCHEMA+'.'+i_s.TABLE_NAME), 'IsMsShipped')=0
-- AND i_s.TABLE_NAME = 'table_name'
ORDER BY
i_s.TABLE_NAME, i_s.ORDINAL_POSITION本回答被提问者采纳 参考技术B describe tableName追问

不明白

转载MS SQL SELECT 获取字段说明/表结构等
