Combining And/Or Eloquent Query in Laravel

Laravel Eloquent Query: Using WHERE with OR AND OR?

Make use of Logical Grouping (Laravel 7.x/4.2). For your example, it'd be something like this:

Model::where(function ($query) {
    $query->where('a', '=', 1)
          ->orWhere('b', '=', 1);
})->where(function ($query) {
    $query->where('c', '=', 1)
          ->orWhere('d', '=', 1);
});

Combining AND/OR eloquent query in Laravel

You can nest where clauses : http://laravel.com/docs/database/fluent#nested-where

Model::where(function($query)
{
    $query->where('a', 'like', 'keyword');
    $query->or_where('b', 'like', 'keyword');
})
->where('c', '=', '1');

This should produce : SELECT * FROM models WHERE (a LIKE %keyword% OR b LIKE %keyword%) AND c = 1

How to combine AND and multiple OR conditions in where clause

In order to group conditions you have to use a closure, you can read more here: https://laravel.com/docs/8.x/queries#or-where-clauses

\DB::table('list')
    ->where('column_A', '>', 100)
    ->where(function($q) use ($conditions) { 
        foreach ($conditions as $condition) { 
            $q->orWhere(...$condition); 
        }  
    });

Laravel - How to combine multiple queries as one Eloquent Query

in your Company Model you should have the relation:

public function HrLeaveRequests()

{
return $this->hasMany(HrLeaveRequest::class,'company_id');
}

now you could use withCount:

 $value=Company::where('company_id',$userCompany)->withCount(['HrLeaveRequests as allLeaves'=>function($query){
            $query ->whereYear('created_at', date('Y'));
        },
            'HrLeaveRequests as pendingLeaves'=>function($query){
                $query->where('leave_status', 1)->whereYear('created_at', date('Y'));
            },
            'HrLeaveRequests as rejectedLeaves'=>function($query){
                $query->where('leave_status', 3)->whereYear('created_at', date('Y'));
            },
            'HrLeaveRequests as approvedLeaves'=>function($query){
                $query->where('leave_status', 4)->whereYear('created_at', date('Y'));
            },
        ])->get();

Laravel eloquent multiple WHERE with OR AND OR and LIKE?

Use like and not like with % in where() and orWhere() methods:

->where('column', 'like', '%pattern%')

https://laravel.com/docs/5.3/queries#where-clauses

If you need to use multiple AND do like this:

->where($condition)
->where($anotherCondition)

If you want to use OR do this:

->where($condition)
->orWhere($anotherCondition)

To combine multiple AND and OR do parameter grouping:

->where('name', '=', 'John')
->orWhere(function ($query) {
    $query->where('votes', '>', 100)
          ->where('title', '<>', 'Admin');
})

How to combine WHERE clauses in Eloquent

To group where clauses like that, you need to pass a closure to the where() method, and add your grouped conditions inside the closure. So, your code would look something like:

Table::where('status', 1)->where(function ($q) {
    return $q->where('type', 2)->orWhere('type', 3)->orWhere('type', 4);
});

This will generate the SQL:

SELECT * FROM tables WHERE status = 1 AND (type = 2 OR type = 3 OR type = 4)

How to Create Multiple Where Clause Query Using Laravel Eloquent?

In Laravel 5.3 (and still true as of 7.x) you can use more granular wheres passed as an array:

$query->where([
    ['column_1', '=', 'value_1'],
    ['column_2', '<>', 'value_2'],
    [COLUMN, OPERATOR, VALUE],
    ...
])

Personally I haven't found use-case for this over just multiple where calls, but fact is you can use it.

Since June 2014 you can pass an array to where

As long as you want all the wheres use and operator, you can group them this way:

$matchThese = ['field' => 'value', 'another_field' => 'another_value', ...];

// if you need another group of wheres as an alternative:
$orThose = ['yet_another_field' => 'yet_another_value', ...];

Then:

$results = User::where($matchThese)->get();

// with another group
$results = User::where($matchThese)
    ->orWhere($orThose)
    ->get();

The above will result in such query:

SELECT * FROM users
  WHERE (field = value AND another_field = another_value AND ...)
  OR (yet_another_field = yet_another_value AND ...)

How to combine these multiple queries in laravel eloquent

$rate = CpfRate::select('cpf_rates.*')
    ->where('cpf_scheme_id', '=', function ($query) use ($request) {
        $query->select('id')
                ->from('cpf_schemes')
                ->where("cpf_citizenship_id", $request->cpf_citizenship_id)
                ->where('cpf_effective_date_id', '=', function($query, $currentDate) {
                    $query->select('id')
                            ->from('cpf_effective_dates')
                            ->where('effective_from', '<=', $currentDate)
                            ->orderBy("effective_from", 'DESC')
                            ->limit(1);
                })
                ->first();
    })
    ->where("minimum_wage", '<', ceil($totalWage)) // query does not accept floats. should be acceptable as wage tiers should be integers
    ->where("minimum_age", '<', $request->employee_age)
    ->orderBy('minimum_wage', 'DESC')
    ->orderBy('minimum_age', 'DESC')
    ->first();

I did not tested but what only here can be problem is $currentdate, so if it is problem just use Carbon class to get current date directly in query.

Laravel break and combine Eloquent query

You aren't saving the query result:

$result = $invoices->get();
dd($result);

Laravel 9 using AND or OR in combination which fails

You are missing the first where about COLUMN1 isn't?

Currently, it produces:

SELECT * FROM table1 WHERE (column2 LIKE 'a' OR column3 LIKE 'b' OR column4 = 'c')

Update your code to include the first where:

DB::table('table1')
    ->where('column1', 'DATA')
    ->where(function ($query) use ($request) {
        $query->where('column2', 'LIKE', $request->data)
          ->orWhere('column3', 'LIKE', $request->data ) 
          ->orWhere('column4', '=', $request->data ) ;
    }
)->get();

And now, it should work as expected (at least, it will produce the query you are expecting).
