收藏幾段SQL Server語句和存儲過程

-- ======================================================

--列出SQL Server 所有表,字段名,主鍵,類型,長度,小數位數等信息

--在查詢分析器裡運行即可,可以生成一個表,導出到Excel中

-- ======================================================

SELECT

(case when a.colorder=1 then d.name else '' end)表名,

a.colorder 字段序號,

a.name 字段名,

(case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√'else '' end) 標識,

(case when (SELECT count(*)

FROM sysobjects

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) 主鍵,

b.name 類型,

a.length 占用字節數,


您正在看的SQLserver教程是:收藏幾段SQL Server語句和存儲過程。 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) 允許空,

isnull(e.text,'') 默認值,

isnull(g.[value],'') AS 字段說明

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 syspropertIEs g

on a.id=g.id AND a.colid = g.smallid

order by a.id,a.colorder
