How to use Complex Query Ranges in Dynamics AX

Use of Complex Query Ranges in Dynamics AX

     1.  Adding a query with a datasource.

query = new Query();
dsInventTable = query.addDataSource(tableNum(InventTable));
// Add our range
queryBuildRange = dsInventTable.addRange(fieldNum(InventTable, DataAreaId));

    2.  Simple criteria

Lets find the record where the value of ItemId field is Item1. Take note of the single quotes and parenthesis surrounding the entire expression.

queryBuildRange.value(strFmt('(ItemId == "%1")', queryValue("Item1")));
Find records where the ItemType is Service. Note the use of any2int().
queryBuildRange.value(strFmt('(ItemType == %1)', any2int(ItemType::Service)));

Find records where the ItemType is Service or the ItemId is Item1. Note the nesting of the parenthesis in this example.

queryBuildRange.value(strFmt('((ItemType == %1) || (ItemId == "%2"))', any2int(ItemType::Service), queryValue("Item1")));

Find records where the modified date is after 1st January 2000. Note the use of Date2StrXpp() to format the date correctly.

queryBuildRange.value(strFmt('(ModifiedDate > %1)', Date2StrXpp(01012000)));

    3.  Complex criteria with combined AND and OR clauses

We need to find those records where the ItemType is Service, or both the ItemType is Item and the ProjCategoryId is Spares. This is not possible to achieve using the standard QueryRange syntax.

queryBuildRange.value(strFmt('((%1 == %2) || ((%1 == %3) && (%4 == "%5")))',fieldStr(InventTable, ItemType),any2int(ItemType::Service),any2int(ItemType::Item),fieldStr(InventTable, ProjCategoryId),queryValue("Spares")));

    ADO Connection:

ADO is a set of COM objects for accessing databases or data stores. In AX we have following Classes/Objects which help to implementing ADO concept.

Class Name	Description
CCADOConnection	Helps in establishing a connection to the target database.
CCADOCommand	Helps in executing a command (a Text type or a Stored procedure)
CCADORecordSet	Stores the data
CCADOFields	A collection of all fields in CCADORecordSet
CCADOField	A single field from the collection of fields
CCADOParameter	A class that helps in passing parameters that a command needs or demands

Here is an example:

static void dbCCADOConnection(Args _args)
{
    CCADOConnection connection = new CCADOConnection();
    CCADOCommand    ccADOCommand;
    CCADORecordSet  record;
    str connectStr = "Provider=SQLNCLI.1;Integrated Security=SSPI;"+
                     "Persist Security Info=False;Initial Catalog=AXDEVDB;Data Source= theAxapta";

    COM     recordSet;  /*This is required to call moveNext method to parse the record set. In AX 4.0 this method was there in the CCADORecordSet class but in AX 2009 this has been deleted*/
    ;

    // Executing a SQL Statement
    try
    {
        connection.open(connectStr);
        ccADOCommand = new CCADOCommand();
        ccADOCommand.commandText("Select * from CustTable where DataAreaId = ‘CEU’");
        ccADOCommand.activeConnection(connection);
        record = ccADOCommand.execute();
        recordSet = record.recordSet();
        while (!record.EOF())
        {
            info(any2str(record.fields().itemIdx(0).value()));
            recordSet.moveNext();
        }
    }
    catch
    {
        error("An Exception has occurred");
    }

    connection.close();
}
