Use macro within a SELECT statement

The SELECT-Statement in the example lists only active BOM items (Table BOM) on (active using the fields FromDate and ToDate). If the second parameter of the macro is empty (zero date ()), so all BOM items are listed.

static void useMacroInSelectStatement(Args _args)
{
    bom bom;
    date emptyDate;
    
    // parameters: %1 = table instance, %2 date, %3 empty date value
    #localmacro.bomDateFilter
        && ( %2 == dateNull() || (
            ((%1.FromDate <= %2) && (%1.ToDate >= %2)) ||
            ((%1.FromDate == %3) && (%1.ToDate == %3)) ||
            ((%1.FromDate <= %2) && (%1.ToDate == %3)) ||
            ((%1.FromDate == %3) && (%1.ToDate >= %2))
            ))
    #endMacro
    ;
    
    while select bom
    where bom.ItemId == '123'
    #bomDateFilter(bom, systemDateGet(), emptyDate)
    {
        info(bom.bomid);
    }
}
