I have an orders table where there is a status column.
I am trying to get the count of each status like this :
$pending = Order::where('status','=','pending')->count();
$active = Order::where('status','=','active')->count();
But this is not efficient as am having to make one call for each status type.
How can I reduce number of queries ?
To make an SQL request:
SELECT count(DISTINCT `status_id`) FROM `dbname`.orders WHERE `user_id` = '2';
In Laravel you can try the following:
$user->orders()->distinct()->count(["status_id"]);
You could try
$orders = Order::select(DB::raw('count(*) as order_count, status'))
->groupBy('status')
->get();
here is the way you write ->
$users= DB::table('table_name')->distinct()->get(['column_name']);
$users_count = $users->count();

First of all, sorry my english is not so good.
my expected result is i want to get data which (residence unit id =21300 and residence user id null) AND (residence_user_id=25106 and residence_unit_id=21300) in one query
PLS HELP ME. thanks!
MySQL Raw query :
SELECT * FROM table_name where residence_unit_id = 21300 AND (residence_user_id = 25106 OR residence_user_id is null);
Laravel eloquent query :
Model::where('residence_unit_id', 21300)->where(function($query) {
$query->where('residence_user_id',25106)>orWhereNull('residence_user_id');
});
Query :
DB::whereNull('residence_user_id')->orWhereIn('residence_user_id' , [25106])->where('residence_unit_id' , 213100)->get()
i want to get the number of rows returned by a query in Yii. This is my query :
$programsAlreadyExist = $connection->createCommand('
SELECT *
FROM `cat_programme`
WHERE `programme_code` = 513')
->queryAll();
The "COUNT" keyword should return a row containing the requested number. :-)
SELECT COUNT(*) FROM cat_programme WHERE programme_code = 513
Change the SELECT to:
SELECT count (*) FROM cat_programme WHERE programme_code = '513'
Thanks !!
You could also do if via the count() method
For ecample
$programsAlreadyExist = MyModel::find()
->where(['programme_code' => '513'])
->count();
How to use count query in rails 4. I try to use , but I get
undefined method `where' for 57:Fixnum
my sample code is,
#empcount = Employee.count("emp_name")
.where("org_id = ? ", current_user.org_id)
What is the error with that?
Employee.count("emp_name") would return the total count of the employees.emp_name. A logical re-ordering of your query should return the result you're looking for:
#empcount = Employee.where("org_id = ? ", current_user.org_id).count("emp_name")
You are applying .where on integer value returned by count
Change your query to:
#empcount = Employee.where(org_id: current_user.org_id).count
Is this of any use?
#empcount = Employee.where(org_id: current_user.org_id).count
You need to find all employees by org_id and then do a count on all rows returned, right?
I have this query :
$query = mysql_query ("SELECT *
FROM saledb.application
WHERE app_id = (
SELECT app_id
FROM saledb.applicationdetails
WHERE is_hot = '1'
) LIMIT $Kvet,$Zet
");
And I have the following error:
Unable to save result set in
/home/lemondo/lemondosales.itnovations.ge/content/tpl/gtpl/main.php on
line 68
When I changing select item with MAX(app_id) it works but i need show all results. i know where is problem mysql cant choose in one query meny ID but i need alternativ query.
Use the IN predicate instead of = like os:
SELECT *
FROM saledb.application
WHERE app_id IN
(SELECT app_id
FROM saledb.applicationdetails
WHERE is_hot = '1');
$query = mysql_query ("SELECT * FROM saledb.application WHERE app_id IN (SELECT app_id FROM saledb.applicationdetails WHERE is_hot = '1') LIMIT $Kvet,$Zet");
That should do the trick. If you leave '=' and the subquery returns more than one row, you wil get that error. To match all the lines in saledb.application that have the app_id in the result set you need to use "IN" :)
This is the only place that I get all answer ;)
I want to select :
SELECT
RTRIM(LTRIM(il.Num_bloc)) AS Bloc,
RTRIM(LTRIM(il.num_colis)) AS Colis,
cd.transporteur AS Coursier,
cd.origine AS Origine,
cd.destination AS Destinataire,
cd.adresse AS [Adresse Destinataire],
cd.poids AS Poids,
il.Signataire, il.num_cin AS CIN, il.date_livraison AS [Date Livraison]
FROM
dbo.cd
INNER JOIN
dbo.il ON cd.bloc = il.Num_bloc AND dbo.cd.colis = dbo.il.num_colis
WHERE
(il.Num_bloc = RTRIM(LTRIM(#ParamBloc)))
AND (il.num_colis = RTRIM(LTRIM(#ParamColis)))
In the way of getting result if the user put ether #ParamBloc or #ParamColis
Try using IsNull() function.
A simple query would go like this
Select * from yourTable
Where
Num_bloc = ISNULL(#ParamBloc, Num_block) AND
num_colis = ISNULL(#ParamColis, num_colis)
The second parameter would make the expression to true if the #parameter Bloc or Colis is null. This query would be useful for all 4 possible combination of these two parameter.
