Exemples
In the following example, a UDF is defined that takes a very long time to execute. Occasionally, it calls CheckCancelled to determine if the function should exit:
public string LongRunning()
{
try
{
//Enter a long running loop
for (int nIndex = 0; nIndex < 1000; nIndex++)
{
//Exception generated when the query is canceled or Timeout occurs
Context.CheckCancelled();
System.Threading.Thread.Sleep(1000);
}
}
catch (System.Exception ex)
{
Console.WriteLine(ex.Message);
throw ex;
}
return "UDF Allowed to Finish";
}
