正在作一個(gè)關(guān)于SQL SERVER數(shù)據(jù)庫導(dǎo)入Excel文件的程序，要讀取數(shù)據(jù)庫中的列的信息，從網(wǎng)上找了很多資料，終于總結(jié)出來比較理想的sql語句，執(zhí)行后返回的列分別是：表名、列名、列類型、列長度、列描述、是否主鍵，語句如下：
SELECT SysObjects.Name as tb_name, SysColumns.Name as col_name, SysTypes.Name as col_type, SysColumns.Length as col_len, isnull(SysProperties.Value,SysColumns.Name) as col_memo,
case when SysColumns.name in
(select 主鍵=a.name
FROM syscolumns a
inner join sysobjects b on a.id=b.id and b.xtype='U' and b.name<>'dtproperties'
where exists(SELECT 1 FROM sysobjects where xtype='PK' and name in (
SELECT name FROM sysindexes WHERE indid in(
SELECT indid FROM sysindexkeys WHERE id = a.id AND colid=a.colid
)))
and b.name=SysObjects.Name
)
then 1 else 0 end as is_key
FROM SysObjects,SysTypes,SysColumns
LEFT JOIN SysProperties ON (Syscolumns.Id = Sysproperties.Id AND
Syscolumns.Colid = Sysproperties.Smallid)
WHERE (Sysobjects.Xtype ='u' OR Sysobjects.Xtype ='v')
AND Sysobjects.Id = Syscolumns.Id AND SysTypes.XType = Syscolumns.XType
AND SysTypes.Name <> 'sysname' AND Sysobjects.Name Like '%' ORDER By SysObjects.Name, SysColumns.colid
如果只想操作一個(gè)表的，那么把最后的％換成表名就可以了。
