How do you load a dataset and then add conditions?

// Load dataset

var myLoadedQuery = query.load({

id: ‘custworkbook237’

});

// Add joins

var mySalesRepJoin = myLoadedQuery.autoJoin({

fieldId: ‘salesrep’

});

// Add the condition

var thirdCondition = mySalesRepJoin.createCondition({

fieldId: ’email,

operator: query.Operator.START_WITH_NOT,

values: ‘foo’

});
