Hello,
please help me in Csharp for calling a method to retrieve a database value using IBM DB2

//------------------------------
public void CreateMyDB2DataReader(string mySelectQuery,string myConnectionString)
{
DB2Connection myConnection = new DB2Connection(myConnectionString);
DB2Command myCommand = new DB2Command(mySelectQuery, myConnection);
myCommand.Connection.Open();
DB2DataReader myReader = myCommand.ExecuteScalar();
try
{
while (myReader.Read())
{
Console.WriteLine(myReader.GetString(0));
}
}
finally
{
myReader.Close();
myConnection.Close();
}
}
//--------------------

public static void Main(tring[] args)
{
// HOW TO CALL CreateMyDB2DataReader?
// my connection string is: "Database=Mydata;UID=login;PWD=passwd;";
// the query: "select bdate from mytable where item = 'startdate'";

}
//---------------------------------------------

Thank you very much.

Hello,

Your solution is very simple Smile | :) just use ExecuteScalar(..) method intead of the ExecuteReader(..) method.

Hi,
thanks for reply.
I have replaced ExecuteReader by ExecuteScalar, I know it is better for retrieving 1 single value. But my question is How do I use it in the MAIN method?
