RE: Call iSeries program from C# program

Apparently you can call a program without creating a stored procedure and 
pass parms to it both ways if you use the OLE DB provider instead of .Net 
provider. 
Seems to me that functionality was ripped out in the .Net provider since 
the .Net provider only seems to support stored procedure calls. 

Either way works well.

subject: RE: Call iSeries program from C# program 

Bob, the way I do it is to load the iSeries Access .Net Db2 Provider and
call a stored procedure on the iSeries. Below is a code snippet. You
have to create the stored procedure on the iSeries.

using IBM.Data.DB2.iSeries;

try
        {
            cn.Open();
        }
        catch (iDB2Exception ex)
        {
            HandleError("An error occurred on cn.Open()", ex);
            return;
        }
 
        //************************************************************
        // B: define stored procedure - GENERAL parameter style
        //************************************************************
        String sp = "call YourLibrary.YourProgram(@Parm1, @Parm2)";

        iDB2Command cmd;

        try
        {

 
//*************************************************************
          // C: set up command, derive parameters, set input parm values
 
//*************************************************************
          cmd = new iDB2Command(sp, cn);
          cmd.CommandType = System.Data.CommandType.Text;
          cmd.DeriveParameters();

 
//*************************************************************
          // D: Request - get value or set to default
 
//*************************************************************
          cmd.Parameters["@Parm1"].Value = 'initial Value if you need
it'; 
 
//*************************************************************
          cmd.Parameters["@Parm2"].Value = String.Empty;

          cmd.ExecuteNonQuery();
 
          String TestParm = cmd.Parameters["@Parm2"].Value.ToString();
                                 }
                   Catch
                                 {
                                                 // Do Error Stuff
                                 }
