Building and creating a query in AX using X++ or using an object query (QueryStr function)

Below are two simple X++ queries which either build a query by adding a datasource or by calling a query object. These are pretty basic but I think they could help some people out. I can post more complicated ones later on but I think the simplicity of these two could be helpful without overwhelming someone who might be new to AX.

Create and add datasource and range in X++ code:

// Code using X++ to build the query
Query                   query;
QueryRun                queryRun;
QueryBuildDataSource    qbds;
SalesTable              salesTable;
;

query    = new Query();
// Add a datasource to the query
qbds     = query.addDataSource(tableNum(SalesTable));
// Add a range to the newly added datasource.
qbds.addRange(fieldNum(SalesTable,SalesId)).value("00403_1036..00412_1036");
   
queryRun = new QueryRun(query);
   
while(queryRun.next())
{
   salesTable  =   queryRun.get(tableNum(SalesTable));
   info(SalesTable.SalesId + ", " + SalesTable.CustAccount);
}

Use query object in query run functionality:

// Code using a query string
static void Job14(Args _args)
{
    Query                           query;
    QueryRun                        queryRun;
    QueryBuildDataSource            qbds;
    QueryBuildRange                 qbr;      
    EcoResDistinctProductVariant    ecoResDistinctProductVariant;   
    
    query = new query(queryStr(EcoResProductVariantsPerCompany));
    queryRun = new QueryRun(query);
    
    while (queryRun.next())
    {
        ecoResDistinctProductVariant = queryRun.get(tableNum(ecoResDistinctProductVariant));
        
        info (strFmt("%1 - %2", EcoResDistinctProductVariant.SearchName, EcoResDistinctProductVariant.ProductMaster));
    }   
}
