如何获得SQL数据库中备注字段的内容
展开全部
您好:
附一个语句,获取表字段属性和注释。
SELECT 表名 =CASE WHEN a.colorder=1 THEN d.name ELSE '' END
,表说明 =CASE WHEN a.colorder=1 THEN ISNULL(f.value,'') ELSE '' END
,字段序号 =a.colorder
,字段名 =a.name
,标识 =CASE WHEN COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 THEN '√'ELSE '' END
,主键 =CASE WHEN EXISTS(SELECT 1 FROM sysobjects WHERE xtype='PK' AND name IN (
SELECT name FROM sysindexes WHERE indid IN(
SELECT indid FROM sysindexkeys WHERE id = a.id AND colid=a.colid
))) THEN '√' ELSE '' END
,类型 =b.name
,占用字节 =a.length
,长度 =COLUMNPROPERTY(a.id,a.name,'PRECISION')
,小数位数 =ISNULL(COLUMNPROPERTY(a.id,a.name,'Scale'),0)
,允许空 =CASE WHEN a.isnullable=1 THEN '√'ELSE '' END
,默认值 =ISNULL(e.text,'')
,字段说明 =ISNULL(g.[value],'')
FROM syscolumns a
LEFT JOIN systypes b ON a.xusertype=b.xusertype
INNER JOIN sysobjects d ON a.id=d.id AND d.xtype='U' AND d.name<>'dtproperties'
LEFT JOIN syscomments e ON a.cdefault=e.id
LEFT JOIN sys.extended_properties g ON a.id=g.major_id AND a.colid=g.minor_id
LEFT JOIN sys.extended_properties f ON d.id=f.major_id AND f.minor_id=0
-- WHERE d.name='orders' --如果只查询指定表,加上此条件
ORDER BY a.id,a.colorder
