I am using laravel 5.3 and I have some left join query with error in laravel query method.
This is my normal query
SELECT bran.branchName,sch.schoolName From m_schoolbranch bran
LEFT JOIN m_students stu ON stu.schoolNo=bran.schoolNo AND stu.branchNo=bran.branchNo
LEFT JOIN m_school sch ON sch.schoolNo=stu.schoolNo where stu.userNo='0000000001';
And this is my new laravel Query
DB::table('m_schoolbranch')
->join('m_students', 'm_schoolbranch.schoolNo', '=', 'm_students.schoolNo')
->join('m_students', 'm_schoolbranch.branchNo', '=', 'm_students.branchNo')
->join('m_school', 'm_schoolbranch.schoolNo', '=', 'm_school.schoolNo')
->select('m_school.schoolName', 'm_schoolbranch.branchName')
->where('m_students.userNo',$userNo)
->get();
In these query I need to match two column in table m_students so I put like this
->join('m_students', 'm_schoolbranch.branchNo', '=', 'm_students.branchNo')
But i show error...
Tables in the query need to have unique names, otherwise the DB has no way of knowing which m_schoolbranch should be used when evaluating m_schoolbranch.schoolNo.
You could use unique table aliases in your join statements but I recommend using multiple conditions on the join. Just like you use in your original SQL query. See here: https://stackoverflow.com/a/20732468/4437888
DB::table('m_schoolbranch')
->join('m_students', function($join)
{
$join->on('m_schoolbranch.schoolNo', '=', 'm_students.schoolNo');
$join->on('m_schoolbranch.branchNo', '=', 'm_students.branchNo');
})
->join('m_school', 'm_schoolbranch.schoolNo', '=', 'm_school.schoolNo')
->select('m_school.schoolName', 'm_schoolbranch.branchName')
->where('m_students.userNo',$userNo)
->get();

I have following temp tables I wanna join them In query builder but I am failing to do so. I wanna join these 2 tables so I can do i1.imp/i2.imp
$subQuery1 = MyModel::query()
->from("table as i1")
->select(
\DB::raw('sum(col) as col1'),
\DB::raw('co1')
)->where('stamp', '>=', '2022-03-01 14:25:00')
->where('stamp', '<', '2022-03-07 14:30:00')
->groupBy(
'co1'
);
$subQuery2 = MyModel::query()
->from("table as i2")
->select(
\DB::raw('sum(col) as col1'),
\DB::raw('co1')
)->where('stamp', '>=', '2022-03-01 14:20:00')
->where('stamp', '<', '2022-03-07 14:25:00')
->groupBy(
'co1'
);
You can use from, fromSub or table and pass in a subquery instead of a table.
You can do the same with joinSub for joins.
You need to provide an alias though.
For example, to use $subquery1 as the main table and join it with $subquery2, the resulting query could look like this:
$results = DB::query()
->select(.....)
->fromSub($subquery1, 'i1')
->joinSub($subquery2, 'i2', function ($join) {
$join->on('i1.col', '=', 'i2.col');
// ->orOn(....)
});
->where(....)
->get();

I try to join three tables which are named attendances, categories, and users.
my code is
$Attendance= DB::table('users')
->join('categories','users.U_category_id', '=', 'categories.id')
->select('users.*','categories.batch_name')->get();
but I also need to join attendances table where attendances column User_A_ID and users table id are the same. How can I do this?
You can try it with
$Attendance= DB::table('users')
->join('categories','users.U_category_id', '=', 'categories.id')
->join('attendances','users.id', '=', 'attendances.User_A_ID')
->select('users.*','categories.batch_name')->get();
This raw query is working well with two commented lines.
$q = DB::table('stock_items')
->selectRaw('stock_parts.title')
->selectRaw('COUNT(*) as qtyAvailable')
->selectRaw('SUM(shipments.item_cost) as totalValue')
//->selectRaw('stock_alerts.minimum AS minimum')
->join('stock_parts', 'stock_items.stock_part_id', '=', 'stock_parts.id')
->join('shipments', 'shipments.id', '=', 'stock_items.shipment_id')
//->leftJoin('stock_alerts', 'stock_alerts.stock_part_id', '=', 'stock_items.stock_part_id')
->whereNull('stock_items.status')
->where('stock_items.current_stock_id', '=', $stockId)
->groupBy('stock_parts.id')
->get();
The commented lines are needed to get information from another table.
In raw SQL I was using LEFT OUTER JOIN and it works.
Uncommenting those lines it shows this error:
SQLSTATE[42000]: Syntax error or access violation: 1055
Expression #4 of SELECT list is not in GROUP BY clause
and contains nonaggregated column 'rdphone-dev.stock_alerts.minimum'
which is not functionally dependent on columns in GROUP BY clause;
this is incompatible with sql_mode=only_full_group_by (SQL: select stock_parts.title, COUNT(*) as qtyAvailable, SUM(shipments.item_cost) as totalValue, stock_alerts.minimum AS minimum from `stock_items` inner join `stock_parts` on `stock_items`.`stock_part_id` = `stock_parts`.`id` inner join `shipments` on `shipments`.`id` = `stock_items`.`shipment_id` left join `stock_alerts` on `stock_alerts`.`stock_part_id` = `stock_items`.`stock_part_id` where `stock_items`.`status` is null and `stock_items`.`current_stock_id` = 1 group by `stock_parts`.`id`)",
What is the correct way to do LEFT OUTER JOIN in Laravel 5.6?
Every field used in the select has to be included in the group by, I added the minimum column in the groupBy.
$q = DB::table('stock_items')
->selectRaw('stock_parts.title')
->selectRaw('COUNT(*) as qtyAvailable')
->selectRaw('SUM(shipments.item_cost) as totalValue')
->selectRaw('stock_alerts.minimum AS minimum')
->join('stock_parts', 'stock_items.stock_part_id', '=', 'stock_parts.id')
->join('shipments', 'shipments.id', '=', 'stock_items.shipment_id')
->leftJoin('stock_alerts', 'stock_alerts.stock_part_id', '=', 'stock_items.stock_part_id')
->whereNull('stock_items.status')
->where('stock_items.current_stock_id', '=', $stockId)
->groupBy('stock_parts.id', 'minimum')
->get();

I need to convert the following sql query to eloquent query builder.
