Reading Excel worksheets in Dynamics AX using CCADOConnection, CCADOCommand & CCADORecordSet classes

-
Recently I came across Bojan's post on performance improvements using CCADOConnection, CCADOCommand & CCADORecordSet classes for reading Excel sheets. You can read the original post here. Well, there is a minor change in the CCADORecordSet class in Dynamics AX 2009 compared to Dynamics AX 4.0 which most users should be aware of. But I thought of still documenting it here.

The CCADORecordSet.moveNext() method isn't present in AX 2009 anymore. To move to the next recordSet, we should use adoRecordSet.recordSet().moveNext();


void readExcelSheet()
{
    CCADOConnection  adoConnection;
    CCADOCommand    adoCommand;

    CCADORecordSet   adoRecordSet;
    CCADOFields      adoFields;
    CCADOField       adoField;

    int               i,j;
    ;

    adoConnection = new CCADOConnection();

    adoRecordSet = new CCADORecordSet();

    adoConnection.open("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + ExcelFile.text() + ";Extended Properties='Excel 8.0;HDR=No;IMEX=1'");

    adoCommand = new CCADOCommand();
    adoCommand.activeConnection(adoConnection);
    adoCommand.commandText(@"SELECT * FROM [SHEET1$]");

    adoRecordSet = adoCommand.execute();

    while(!adoRecordSet.EOF())
    {
        adoFields = adoRecordSet.fields();

        for (i=0; i<adoFields.count(); i++)
        {
            print adoFields.itemIdx(i).value();
        }

        // The below commented line doesnt work in AX 2009
        // adoRecordSet.moveNext();        
        adoRecordSet.recordSet().moveNext();
    }

    pause;
}


Hope this helps.

I am wondering if you update tables in this manner, will the ID fields still populate correctly? What is your suggestion for loading data with almost a million rows?

Hi Verena,

If you use these classes to insert data, the RecId field wont be populated. It is pretty much the same way how you insert records using direct SQL.

Some upgrade classes make use of the systemSequence class to generate RecIds which are inserted manually then.

The generation of RecId is a concept internal to Dynamics AX. If you are inserting records directly using SQL or Excel, it will be your responsibility to fill in the RecId field as well.

For inserting million of records, you can write direct SQL statements generating and populating the RecId field manually or you can use AIF operations as well in which case the RecId will be generated automatically.

How to add empty ranges in query

-
In Dynamics AX programming, a common mistake I have seen when it comes to query ranges is passing an empty string value to the range. The developer here is expecting it to show all the records where the range field is empty. Instead, what we get is all records without the range being applied. As baffling as it may seems, it is easily explainable. The query engine in Dynamics AX, will not add a range if you don’t specify a value or if you specify an empty string because an empty string is treated as no value. So the following code will result in this SQL statement, query = new Query(); qbds = query.addDataSource(tableNum(ProjTable)); qbr = qbds.addRange(fieldNum(ProjTable, Name)); qbr.value(''); Select first fast * from ProjTable; But what was expected was something like, Select first fast * from ProjTable where Name == ''; So to work around this issue, use the SysQuery::valueEmptyString() static method which parses the empty strings correctly so that it

Get selected records in Dynamics AX 2012

In my earlier post, we discussed how we can retrieve all selected records on a list page. You can read that post here . Retrieving all selected records from a caller form is very easy. The code for this can be found in a number of places in standard Dynamics AX codebase. The general approach is to use the dataSource.getFirst(1) statement to get the first selected record and loop through the remaining using dataSource.getNext() . In Dynamics AX 2009, a new class was introduced for this purpose. This was the MultiSelectionHelper class. In Dynamics AX 2012, another new class has been introduced to retrieve the selected records. This is the MultiSelectionContext class. The MultiSelectionHelper class is an application class. It presents two constrcutors. The standard constructor method just creates a new instance of the MultiSelectionHelper class. When this construct is used, you will have to explicitly set the dataSource to be used for fethcing selected records. This can be done

The field with ID '0' does not exist in table - Cause and resolution.

Hello readers, In Dynamics AX coding, you should have come across this error sometime - The field with ID '0' does not exist in table 'SomeTable' So what causes this error and what is the possible resolution to it? Well, the most likely cause for this error is a missing mapping in a table map. Let us look at an example. I've a simple Map named CustVendAccount with one Account field. I've created two mappings - one with CustTable's AccountNum field and for the otehr mapping, I just specify VendTable but no field. This is how my map looks like, Now, I've a simple job which just passes either CustTable or VendTable as an argument and then we print the Account field in the map. static void CustVendAccountMap(Args _args) { CustTable custTable; VendTable vendTable; void readMap(CustVendAccount _custVendAccount) { info(strFmt("Value from table %1 is %2",tableId2name(_custVendAccount.TableId), _custV
