数据库的查询问题
我做了个连接数据库的程序,但是不知道怎么写查询的代码,希望高手写个简单的代码让我做下参考,谢谢。  
               {
                 sconn = new SqlConnection(@"Integrated Security=SSPI;server=(local);database=pubs");
                 sconn.Open();
                 }
           private void button2_Click(object sender, EventArgs e)
           {
               string commstr = @"select * from titles";
               scomm = new SqlCommand(commstr, sconn);
               sdr = scomm.ExecuteReader();
               if (sdr.Read())
               {
                   textBox1.Text = sdr.GetValue(1).ToString();
                   textBox2.Text = sdr.GetValue(2).ToString();
               }
           }
------解决方案--------------------楼主最好把问题说清楚一点,好像有点看不懂问题。
------解决方案--------------------SqlConnection conn = new SqlConnection(@"Integrated Security=SSPI;server=local);database=pubs");  
string mysql="select * from titles";  
SqlDataAdapter myDapter=new SqlDataAdapter(mysql,conn);
DataSet ds=new DataSet();  
myDapter.Fill(ds);  
DataTable dt = ds.Tables[0];  
if(dt.Rows.Count >=1)  
textBox1.Text  = dt.Rows[0][0].ToString();
textBox2.Text  = dt.Rows[0][1].ToString();
------解决方案--------------------C# code
SqlConnection conn = new SqlConnection(@"Integrated Security=SSPI;server=local);database=pubs");  
string mysql="select * from titles";  
SqlDataAdapter myDapter=new SqlDataAdapter(mysql,conn); 
DataSet ds=new DataSet();  
myDapter.Fill(ds);  
DataTable dt = ds.Tables[0];  
if(dt.Rows.Count  >=1)  
{
textBox1.Text  = dt.Rows[0][0].ToString(); 
textBox2.Text  = dt.Rows[0][1].ToString(); 
}
