title: Error : Parameter name not found, in Postgresql
body: <p>I am working in Asp.net with postgresql with devart dotconnect connection driver.
  When i am executing a parmeterized query it is showing error, </p>
  
  <blockquote>
    <p>Parameter name not found</p>
  </blockquote>
  
  <p>My code is below</p>
  
  <pre><code>Command = new Devart.Data.PostgreSql.PgSqlCommand();
  Command.Parameters.AddWithValue("@TestName", testmaster.TestName);
  Command.Parameters.AddWithValue("@TestShortName", testmaster.TestShortName);
  DAF.Command.CommandText = @"Do $$
  DECLARE newTestID INT;
  BEGIN
  "+"Insert into \"TestMaster\"(\"TestName\", \"TestShortName\", \"RCUID\", \"RCDate\", \"RCTime\") " + @"
      "+"values (:TestName, :TestShortName, 0, CURRENT_DATE, CURRENT_TIME(0)) " + @"
      "+"RETURNING \"TestID\" INTO newTestID;"+@"
  END$$;";
  
  // Rest is execution code
  </code></pre>
  
  <p>What i am making a mistake here ?</p>
  
  <p>Edit : I got on which code this message is occurring, it is not on insert command it is on returning command. </p>
