有什么办法可以查SQL数据库某个表的表头

[raynors]

我用C# WEB 服务页查询数据库 用XML格式发送给客户端,但是无法取得数据库表头啊,不知道各位大哥有什么办法.

就是查询表头用什么办法

strSql = "SELECT COUNT(*) FROM " + TableName+ " "+InputNod.InnerText;
sqlcmd=new SqlCommand (strSql ,sqlconn );
record= sqlcmd.ExecuteReader();
record.Read();
int RecordCount = record.GetInt32(0);
record.Close();

上面是我取得数据记录数的办法.

你是想获得数据库表的结构吗，如果是的话，参看：
-- ======================================================

--列出SQL SERVER 所有表，字段名，主键，类型，长度，小数位数等信息

--在查询分析器里运行即可,可以生成一个表，导出到EXCEL中

-- ======================================================




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 COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√'else '' end) 标识,

(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 '√' else '' end) 主键,

b.name 类型,

a.length 占用字节数,

COLUMNPROPERTY(a.id,a.name,'PRECISION') as 长度,

isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0) as 小数位数,

(case when a.isnullable=1 then '√'else '' end) 允许空,

isnull(e.text,'') 默认值,

isnull(g.[value],'') AS 字段说明



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 sysproperties g

on a.id=g.id AND a.colid = g.smallid

order by a.id,a.colorder

好象用dataReader能实现吧。
记不太清楚了。可能是这样：
for(int;i=0;i<=this.dataadapter.fieldcount-1;i++)
{
this.combobox1.items.add(dataadapter.getname());//这里你自己试验一下，我记不太清楚了
}
