正在作一个关于 SQL SERVER 数据库 导入Excel文件的程序,要读取数据库中的列的信息,从网上找了很多资料,终于总结出来比较理想的 sql 语句,执行后返回的列分别是:表名、列名、列类型、列长度、列描述、是否主键,语句如下: SELECT SysObjects.Name as t

正在作一个关于SQL SERVER数据库导入Excel文件的程序,要读取数据库中的列的信息,从网上找了很多资料,终于总结出来比较理想的sql语句,执行后返回的列分别是:表名、列名、列类型、列长度、列描述、是否主键,语句如下:

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 主键=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

如果只想操作一个表的,那么把最后的%换成表名就可以了。
