SQL Server 關于 Table 字典資料的查詢SQL

分享一個關于查詢SQL Server Table 結構的SQL 語句。

T-SQL 如下：

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

a.colorder 字段序号,a.name 字段名,

(case when a.colorder=1 then isnull(f.value,'') else '' end) 表說明,

(case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '1'else '0' end)辨別,

(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 '1' else '0' end) 主鍵,b.name 類型,a.length 占用位元組數,

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 '1'else '0' end) 允許空,

isnull(e.text,'') 預設值,isnull(g.[value], ' ') AS [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 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 b.name is not null

WHERE d.name='DBA_Server' --如果隻查詢指定表,加上此條件，此案例為表DBA_Server

order by a.id,a.colorder

 查詢出的結果如下：
