Hi, I am trying to get the value from sql query which getting the sum of an specific column. I want it to display on textbox/label so that I could insert it to another table. How can I do this? I am using Oracle.DataAccess. I am trying that ExecuteScalar but it gives me an error. What to do? Thanks! Here is my code:

C#

   eSQl = "SELECT sum(inttotal) FROM tbltrans where                   prj_code='"+txtPrjCod.Text+"' group by prj_code";

 SQLdr = DBCon.show(eSQl);

 while (SQLdr.Read())

 {

   tot = Convert.ToInt32(SQLdr.GetOracleValue(30).ToString());

   textBox1.Text = tot.ToString();

}

SQLdr.Close();

Hi,

Please update your query as below.

C#

eSQl = "SELECT sum(inttotal)as TOTAL FROM tbltrans where prj_code='"+txtPrjCod.Text+"'";

Then read value from dr as

C#

while (SQLdr.Read())
{
   tot = Convert.ToInt32(SQLdr.GetOracleValue(0).ToString());
   textBox1.Text = tot.ToString();
}
