復制代碼 代碼如下:
SELECT
(case when a.colorder=1 then d.name else '' end) as 表名,--如果表名相同就返回空 syscolumns(表字段信息表) a sysobjects d
a.colorder as 字段序號,
a.name as 字段名,
(case when COLUMNPROPERTY( a.id,a.name, 'IsIdentity' )=1 then '√' else '' end) as 標識, --返回IsIdentity的值，IsIdentity只有兩個值：0、1
(case when (SELECT count(*) FROM sysobjects--查詢主鍵
WHERE (name in
(SELECT name FROM sysindexes
WHERE (id = a.id) AND (indid in
(SELECT indid FROM sysindexkeys
WHERE (id = a.id) AND (colid in
(SELECT colid FROM syscolumns
WHERE (id = a.id) AND (name = a.name))
)))))
AND (xtype = 'PK' ))>0 then '√' else '' end) as 主鍵,--查詢主鍵END
b.name as 類型, --systypes b
a.length as 占用字節數,
COLUMNPROPERTY(a.id,a.name,'PRECISION' ) as 長度,
isnull(COLUMNPROPERTY(a.id,a.name,'Scale' ),0) as 小數位數,
(case when a.isnullable=1 then '√' else '' end) as 允許空,
isnull(e.text,'' ) as 默認值, --syscomments e
isnull(g.[value],'' ) AS 字段說明 --sys.extended_properties g (字段信息表)
FROM syscolumns a left join systypes b
on a.xtype=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
where d.name='systempara' --所要查詢的表
order by a.id,a.colorder
