1.查詢資料庫中的所有資料庫名：

 SELECT Name FROM Master..SysDatabases ORDER BY Name

2.查詢某個資料庫中所有的表名：

 SELECT Name FROM SysObjects Where XType=‘U‘ ORDER BY Name

3.查詢表結構資訊：

 1 SELECT (case when a.colorder=1 then d.name else null end) 表名,   2 a.colorder 欄位序號,a.name 欄位名, 3 (case when COLUMNPROPERTY( a.id,a.name,‘IsIdentity‘)=1 then ‘√‘else ‘‘ end) 標識,  4 (case when (SELECT count(*) FROM sysobjects   5 WHERE (name in (SELECT name FROM sysindexes   6 WHERE (id = a.id) AND (indid in   7 (SELECT indid FROM sysindexkeys   8 WHERE (id = a.id) AND (colid in   9 (SELECT colid FROM syscolumns WHERE (id = a.id) AND (name = a.name)))))))  10 AND (xtype = ‘PK‘))>0 then ‘√‘ else ‘‘ end) 主鍵,b.name 類型,a.length 佔用位元組數,  11 COLUMNPROPERTY(a.id,a.name,‘PRECISION‘) as 長度,  12 isnull(COLUMNPROPERTY(a.id,a.name,‘Scale‘),0) as 小數位元,(case when a.isnullable=1 then ‘√‘else ‘‘ end) 允許空,  13 isnull(e.text,‘‘) 預設值,isnull(g.[value], ‘ ‘) AS [說明]14 FROM  syscolumns a 15 left join systypes b on a.xtype=b.xusertype  16 inner join sysobjects d on a.id=d.id and d.xtype=‘U‘ and d.name<>‘dtproperties‘ 17 left join syscomments e on a.cdefault=e.id  18 left join sys.extended_properties g on a.id=g.major_id AND a.colid=g.minor_id19 left join sys.extended_properties f on d.id=f.class and f.minor_id=020 where b.name is not null21 --WHERE d.name=‘要查詢的表‘ --如果只查詢指定表,加上此條件22 order by a.id,a.colorder
