query with two key get one object in parse using swift

Question

I am using parse in my app and I want to satisfy the two query and return object without using orQueryWithSubqueries. Here my query to parse code:

func queryToParse(){
    var queryForBlood = PFQuery(className: "Donors")
    queryForBlood.whereKey("BloodGroup", equalTo: bloodGroupTextField.text)
    var queryForCity = PFQuery(className: "Donors")
    queryForCity.whereKey("City", equalTo: citySearchTextField.text)
    var query = PFQuery.orQueryWithSubqueries([queryForCity,])
    query.findObjectsInBackgroundWithBlock { (objects, error) -> Void in
        if error == nil {
            self.tableData = objects as NSArray
            println(self.tableData)
            self.tableView.reloadData()
        }
        else
        {
            println(error)
        }
    }
}

my code only satisfy any one of the key but i want both to satisfy the key value and return objects — bhuvan alagesan

Do you want the 'and' of the two keys - donors in the specified city with the specified blood group? If so the simply call whereKey twice on the same query with the two different criteria — Paulw11

i try this but it returns nothing ...var query = PFQuery(className: "Donors") query.whereKey("BloodGroup", equalTo: bloodGroupTextField.text) query.whereKey("City", equalTo: citySearchTextField.text) query.findObjectsInBackgroundWithBlock { (objects, error) -> Void in if error == nil{ self.tableData = objects as NSArray println(self.tableData) self.tableView.reloadData() } else { println(error) } } } — bhuvan alagesan

Please improve this question. Present a sample of the data from the data browser that the query should find or not find. Be clear in writing about what you want, which two keys and whether you want records that meet both or either condition. — danh

Instead of creating two separate PFQuery, then you just have to create one. You only need to create several PFQuery when you want to make an OR query.

Your code should look something like this:

func queryToParse(){
    let query = PFQuery(className: "Donors").whereKey("BloodGroup", equalTo: bloodGroupTextField.text).whereKey("City", equalTo: citySearchTextField.text)
    query.findObjectsInBackgroundWithBlock { (objects, error) -> Void in
        ...
    }
}
