private void RunStoredProcedure()

string customer_name = "";
var conn = new OdbcConnection();
conn.ConnectionString = @"DSN=ABCD;" +
"Uid=TAB;" +
"Pwd='******';
OdbcCommand command = new OdbcCommand("{? = CALL GETUSERNAME(?)}", conn);

        OdbcParameter parameter2 = new OdbcParameter();

        parameter2.Size = 255;
        parameter2.Direction = ParameterDirection.ReturnValue;
        command.Parameters.Add(parameter2);

        OdbcParameter parameter = new OdbcParameter();

What is your question?

3

I get an error when I execute the code

4

The error comes up at executenonquery()

I named the two parameters parameter and parameter1. Do I call them the same name?might that be the problem?

5

Please post the error?

yosiasz is right -- the first step is to post the error exactly as it occurs, with any line number information it puts out.

But with a cursory look, I noticed this:

conn.ConnectionString = @"DSN=ABCD;" +
"Uid=TAB;" +
"Pwd='******';

Are you missing a double quote after the last semicolon?

The connection string works; I might have missed the semi colon when I pasted it into the forum. I will copy the error tomorrow since I have left work. Thank you and hope to hear back from you tomorrow.

We are hoping to hear back from you with the error :wink:
