Question

I’ve created a query to select the body of a message from the message database. I’m not sure how to execute it to get the body string back and store it. I’ve tried using ExecuteReader, ExecuteScalar, and ExecuteNonQuery. None of them work. ExecuteScalar was the closest to working but it only returned the body of the message of the first row no matter which row you were trying to view. Anyone know how to do this? It’s gotta be a easy fix.

  SqlCommand com = new SqlCommand("SELECT Body FROM Messages WHERE MessageID=               MessageID", conn);
  com.Connection = conn;
  com.Connection.Open();
  String body;
  body = com.ExecuteScalar.ToString;

That’s what I have now. Thanks in advance!

What is messageId in your query? You should be doing something like this

SqlCommand com = new SqlCommand("SELECT Body FROM Messages WHERE MessageID = @MessageId");
com.Parameters.AddWithValue("@MessageId", 1); //Replace 1 with messageid you want to get
string s = com.ExecuteScalar().ToString()
