Process a Mining Model Programmatically

I have tried to process a data mining model that I have produce programmatically. I use the following code for processing

Private Sub BtProcess_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtProcess.Click

' Now some different styles of processing

'Process mining structure first - don't process the models though

' ms.Process(ProcessType.ProcessStructure)

ms.Process(ProcessType.ProcessStructure)

DeclareBox.Text = "Process Data Mining Structure"

' Process the mining model only (because the structure has been processed above

' We could have said ProcessDefault without processing the structure first, though

mm.Process(ProcessType.ProcessDefault)

DeclareBox.Text = "Process Data Mining Model"

End Sub

I use the following code for data mining model and is correctly designed

Private Sub CreateMiningModel()

Dim mc As MiningModelColumn

mm = ms.MiningModels.Add(CbDatabase.Text & " miningmodelName") ', Utils.GetSyntacticallyValidID(miningmodelName, Type.GetType(MiningModel)))

mm.Algorithm = "Microsoft_Decision_Trees"

mm.AlgorithmParameters.Add("COMPLEXITY_PENALTY", 0.3)

mc = New MiningModelColumn("SUMCODE", "SUMCODE")

mc.SourceColumnID = ms.Columns("SUMCODE").ID

mc.Usage = "Key"

mm.Columns.Add(mc)

mc = New MiningModelColumn("STAFF_YES", "STAFF_YES")

mc.SourceColumnID = ms.Columns("STAFF_YES").ID

mc.Usage = "Input"

mm.Columns.Add(mc)

mc = New MiningModelColumn("D_G_OZODIS_IPER", "D_G_OZODIS_IPER")

mc.SourceColumnID = ms.Columns("D_G_OZODIS_IPER").ID

mc.Usage = "PredictOnly"

mm.Columns.Add(mc)

and I received the following error message. Any Ideas? What is wrong with this? Thank you in advance

There seems to be an error converting the STAFF_YES values to the mining structure column type. What is the data type (in the database) for this column and what is the Mining Structure column type for this column?

I thing that you are correct

In the database STAFF_YES is of type bit and in the mining structure is a text. I tried to convert the type in the mining structure to bit but I did not find such a type. How can I do that programmatically? Do I have to change anything to the database? I hope not

Thank you in advance

I tried this code

mc = New MiningModelColumn("STAFF_YES", STAFF_YES, Type.GetType(MiningModelColumn)))

I received an error in MiningModelColumn, what is the problem with MiningModelColumn. Is there any other code?

Thank you in advance

Bit should work fine when represented (in the mining structure) as Boolean.

Can you try to change the structure column type to boolean and then retrain your model? The data type is specific to the mining structure column (not the mining model column)

Thank you very much your advice worked perfectly.

My problem now is to get the type programmatically and not type OleDbType.Boolean by me

Can I try the following code?

Seems that does not work?

What do I have to use for the ScalarMiningStructureColumn

smsc = New ScalarMiningStructureColumn("D_G_OZODIS_IPER") , Utils.GetSyntacticallyValidID("VISIT"), Type.GetType(ScalarMiningStructureColumn)))

smsc.IsKey = False

smsc.Content = "Discrete"

smsc.KeyColumns.Add("VISIT", "D_G_OZODIS_IPER", OleDbType.Boolean)

ms.Columns.Add(smsc)

Thank you in advance
