Devart.Common Namespace / DbScript Class / Error Event
Example

Error Event (DbScript)
Occurs when a SQL statement within script has produced an error.
Syntax
'Declaration
 
Public Event Error As ScriptErrorEventHandler
 
Event Data

The event handler receives an argument of type ScriptErrorEventArgs containing data related to this event. The following ScriptErrorEventArgs properties provide information specific to this event.

PropertyDescription
Gets the System.Exception instance that DbScript throws.  
Gets or sets whether the current error will be ignored or not.  
Gets length of statement where an error occurred.  
Gets number of the line where an error occurred.  
Gets position in the line where an error occurred.  
Gets offset of statement where an error occurred.  
Gets type of the statement that caused an error.  
Gets SQL statement where an error occurred.  
Remarks

This event can be generated by Execute and ExecuteNext methods when an error happens.

By default, Execute method stops and returns immediately after event handler finishes. If you want to ignore the error and continue execution of the script, set ScriptErrorEventArgs.Ignore property to true.

Example
This sample demonstrates how to execute script and retrieve information about execution flow using Progress and Error events.
[STAThread]
static void Main(string[] args)
{
string script =

  "INSERT INTO DEPT VALUES (10,'ACCOUNTING','NEW YORK');"+
  "INSERT INTO DEPT VALUES (20,'RESEARCH','DALLAS');"+
  "INSERT INTO DEPT VALUES (30,'SALES','CHICAGO');"+
  "INSERT INTO DEPT VALUES (40,'OPERATIONS','BOSTON');"+
  "SELECT * FROM DEPT";
      SqlConnection myConn = new SqlConnection(
          "User Id=sa;Server=localhost;Initial Catalog=Test;");
      SqlScript myScript = new SqlScript(script,myConn);
      myScript.Progress += new Devart.Common.ScriptProgressEventHandler(OnProgress);
      myScript.Error += new Devart.Common.ScriptErrorEventHandler(OnError);
      myConn.Open();
      myScript.Execute();
      myConn.Close();
    }

static void OnProgress(object sender, Devart.Common.ScriptProgressEventArgs e)
{
  Console.WriteLine(e.Text);
  Console.WriteLine("  Successfully executed.");
}

static void OnError(object sender, Devart.Common.ScriptErrorEventArgs e)
{
  e.Ignore = true;
  Console.WriteLine(e.Text);
  Console.WriteLine("  Failed.");
}
