Question

I am trying to add some more native error handling to an SSIS C# Script Component (in Data-Flow). Right now I force it to crash the component with 1/0 which works but is hackish.

My script does some jazz on input data, but I would like to validate it at several steps and fail the component if any validations fail. The source is a select, so i don’t need to
roll back any transactions etc… but I would like the component to fail the dataflow so the dataflow component will fail and follow the error handling I prescribe in control flow.

Here is the simplist relavant snippet that is holding me up:

using System;
using System.Data;
using Microsoft.SqlServer.Dts.Pipeline.Wrapper;
using Microsoft.SqlServer.Dts.Runtime.Wrapper;

[Microsoft.SqlServer.Dts.Pipeline.SSISScriptComponentEntryPointAttribute]
public class ScriptMain : UserComponent
{


public override void PreExecute()
{
    base.PreExecute();
    /*
      Add your code here for preprocessing or remove if not needed
    */

    bool pbCancel = false;
    ////check Row Count>0
    if (Variables.WeeklyLRrowCount == 0)
        this.ComponentMetaData.FireError(-1, "", "Fails Validation due to Empty Table.", "", 0, out pbCancel);
}

public override void PostExecute()
{
    base.PostExecute();
    /*
      Add your code here for postprocessing or remove if not needed
      You can set read/write variables here, for example:
      Variables.MyIntVar = 100
    */

}

public override void Input0_ProcessInputRow(Input0Buffer Row)
{
    /*
      Add your code here
    */

}


}

I get the following from SSIS:

"The name 'FireError' does not exist in the current context."

Is there something I am missing here?

Thanks!

You should just move your code to the PostExecute method.
