ExtendedFunctions

#ExtendedFunctions

This list allows the user specify additional SQL functions that should be included in the functions dropdown of the Fields tab.

Below is a sample global.asax using the ExtendedFunctions setting. The code block will appear within <script runat="server"> </script> tags within global.asax.

##Global.asax (C♯)

//main class: inherits DatabaseAdHocConfig or FileSystemAdHocConfig
public class CustomAdHocConfig : Izenda.AdHoc.DatabaseAdHocConfig
{
  // Configure settings
  // Add custom settings after setting the license key and connection string by overriding the ConfigureSettings() method
  public static void InitializeReporting() {
    //Check to see if we've already initialized.
    if (HttpContext.Current.Session == null || HttpContext.Current.Session["ReportingInitialized"] != null)
      return;
    AdHocSettings.LicenseKey = "INSERT_LICENSE_KEY_HERE";
    //Creates a connection to Microsoft SQL Server
    AdHocSettings.SqlServerConnectionString = "INSERT_CONNECTION_STRING_HERE";
    Izenda.AdHoc.AdHocSettings.AdHocConfig = new CustomAdHocConfig();
    AdHocSettings.ExtendedFunctions = new string[] { "[dbo].[SafeDivide]" };
    HttpContext.Current.Session["ReportingInitialized"] = true;
  }
}

##Global.asax (VB.NET)

'main class: inherits DatabaseAdHocConfig or FileSystemAdHocConfig
Public Class CustomAdHocConfig
    Inherits Izenda.AdHoc.DatabaseAdHocConfig

    Shared Sub InitializeReporting()
        'Check to see if we've already initialized
        If HttpContext.Current.Session Is Nothing OrElse HttpContext.Current.Session("ReportingInitialized") IsNot Nothing Then
            Return
        'Initialize System
        AdHocSettings.LicenseKey = "INSERT_LICENSE_KEY_HERE"
        AdHocSettings.SqlServerConnectionString = "INSERT_CONNECTION_STRING_HERE"
        Izenda.AdHoc.AdHocSettings.AdHocConfig = New CustomAdHocConfig()
        AdHocSettings.ExtendedFunctions = New String() { "[dbo].[SafeDivide]" }
        HttpContext.Current.Session("ReportingInitialized") = True
    End Sub
End Class
