KB7332: How to Retrieve Column Data Type Information For an Attribute in MicroStrategy Intelligence Server SDK 9.x

 
There is only one form 'ID' associated with this attribute, but with two expressions 'Date_Id' and 'Order_Date'. Each expression is linked to three database tables.
 
The following sample code shows how to retrieve column data type information by using IDSSColumn::DataType API call.
 

'obtain the attribute object 
    Dim dateAttr As IDSSAttribute 
    Set dateAttr = mobjObjSource.Schema.Attributes.Item(10) 
    'index 10 is for "date" attribute. In real programming you may obtain this attribute by searching 
    
    'search for all tables that this attribute linked to 
    Dim oSearch As IDSSSearch 
    Set oSearch = mobjObjSource.NewObject(DssTypeSearch) 
    
    oSearch.Clear 
    oSearch.Types.Add DssTypeTable 
    oSearch.Uses.Add dateAttr.Info 
    
    Dim oResult As IDSSFolder 
    Set oResult = mobjObjSource.ExecuteSearch(oSearch) 
    
    Dim aTable As IDSSTable Dim i, j 
        'loop into the all these tables and find the information related to this attribute 
        
        For i = 1 To oResult.Count 
            Set aTable = oResult.Item(i).Special 
        
            For j = 1 To aTable.AttributeInfos.Count 
                If aTable.AttributeInfos.Item(j).Attribute.Info.Name = "Date" Then 
                    MsgBox aTable.AttributeInfos.Item(j).LocalDefn.BaseForms.Item(0).Expression.Text 
                    MsgBox aTable.AttributeInfos.Item(j).LocalDefn.BaseForms.Item(0).Column.DataType.Type 
                End If 
            Next 
        Next
