如何取得数据库（sql server 2k）中一个表的某一行某一列的值！3ks for your help！

[xboy]

如题，不要用存储过程弄哦

[91bct]

string sql="select myfield1 from mytable where id='"+sID+"'";//指定某一行的条件
SqlCommand cmd=new SqlCommand(sql,conn);
DataReader reader=cmd.ExecuteReader();
conn.Open();
string sResult;
where(reader.Read())
{
sResult=reader.GetValue(...);
}
reader.Close();
conn.Close();
大致是这样的，你可以差一下MSDN

补充一下：
SqlCommand cmd2=new SqlCommand(s,Conn);
SqlDataReader read=cmd2.ExecuteReader();
while(reader.Read())
{
reader.GetString(0);
//或 read.GetString(0);
}

什么意思？
是指按读出记录集的顺序得到其中某一行某一列值？

那试试下面两句SQL吧
select INDENTITY(int,1,1) AS ID_NUM,列名 into #temp from 表
Select 列名 from #temp where ID_NUM =你要的行号

建一个SqlDataAdapter(SqlDa)连接到你的Sql Server的一个表上

DataSet ds_target = new DataSet();
SqlDa.Fill(ds_target,"test");
ds_target.Tables["test"].Rows[某一行][某一列] = 你要取得值


你的系统中不会真这么用吧！

public void ReadMyData(string myConnString) {
string mySelectQuery = "SELECT OrderID, CustomerID FROM Orders";
SqlConnection myConnection = new SqlConnection(myConnString);
SqlCommand myCommand = new SqlCommand(mySelectQuery,myConnection);
myConnection.Open();
SqlDataReader myReader;
myReader = myCommand.ExecuteReader();
// Always call Read before accessing data.
while (myReader.Read()) {
Console.WriteLine(myReader.GetInt32(0) + ", " + myReader.GetString(1));
}
// always call Close when done reading.
myReader.Close();
// Close the connection when done with it.
myConnection.Close();
}
