[Blog bot]

==============

 
 
        Sometime back i had a posting referring to Gloomies blog (click to see the old posting) on using ADO in Ax. Gloomie had  used COM based ADO control. Ax also has  predefined ADO Com classes which  you can use....
 
  Here's a small Job that will help you in working with the Inbuild ADO classes
 
static void JobADOtoAccessExcelInAxapta(Args _args)
{
    CCADOConnection  adoexcel     = new CCADOConnection();
    CCAdoxCatalog    adoCatalog   = new CCAdoxCatalog();
    COM              adoxCatalog  = new COM('ADOX.Catalog');
    CCADORecordSet   adoRecordSet = new CCADORecordSet();
    CCADOFields      adoFields;
    CCADOField       adoField;
    int               i;
    ;
    adoexcel.connectionString("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=  
    C:\TestAdo.xls  ;Extended Properties='Excel 8.0;HDR=Yes;IMEX=1'");
    adoexcel.open();
    adoxCatalog.activeConnection(adoexcel.connection());
    adoCatalog.adoxCatalog(adoxCatalog);
    print adoCatalog.tableName(1);
    pause;
    adoRecordSet.open(@"SELECT * FROM [SHEET1$]", adoexcel);
    adoFields = adoRecordSet.fields();
    for (i = 0; i < adoFields.count(); i++)
    {
        adoField = adoFields.itemIdx(i);
        print adoField.name();
        pause;
    }
    while (! adoRecordSet.EOF())
    {
        for (i = 0; i < adoFields.count(); i++)
        {
            adoField = adoFields.itemIdx(i);
            print adoField.value();
            pause;
        }
        adoRecordSet.moveNext();
    }
}
 
 
Here is a snap shot of the excel that i used for the job....

Вот меня всегда интересовал вопрос как правельно наложить фильтр на запрос

adoRecordSet.open(@"SELECT * FROM [SHEET1$]", adoexcel);

например по полю name=konopello или city=Minsk
