SQL Server 關於 Table 字典資料的查詢SQL

分享一個關於查詢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 欄位序號,a.name 欄位名,(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)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 sysindexkeysWHERE (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 型別,a.length 佔用位元組數, COLUMNPROPERTY(a.id,a.name,'PRECISION') as 長度,
isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0) as 小數位數,(case whena.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' --如果只查詢指定表,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:
