    queryBuildDataSource1 = query.addDataSource(tablenum(CarTable));
    // Add the range to this first data source
    queryBuildRange = queryBuildDataSource1.addRange(fieldnum(CarTable, ModelYear));
    // Add the second datasource to the first data source
    queryBuildDataSource2 =   queryBuildDataSource1.addDataSource(tablen
    um(RentalTable));
    // Add the link from the child data source to the
    //parent data
    source
    queryBuildLink = queryBuildDataSource2.addLink(fieldnum(CarTable,
    CarId),fieldnum(RentalTable, CarId));
}

Note:
This process (query through X++ code) is very similar to create a query directly through AOT node.
AOT -> Query -> Right Click -> New Query
I would suggest first create a query through query node, than go for this code.
