在WHERE中应用OR子句，或在雄辩的laravel中应用HAVING

Question

I am working on a laravel project for building REST api. I am using eloquent to fatch data from database. I am facing issues in applying the OR condition in WHERE, HAVING etc. If there is only one where and one orWhere condition, it has no issues but here I am taking multiple where clause. Like if we write core mysql query we can write like

SELECT * FROM table_name WHERE uid = 1 
AND (id = 1 AND name = test1) OR (id = 2 AND name = test2);

But when we work with eloquent and if we use orWhere in models, for that we need to do something like

Model::select('*')->where('uid', '1')
->where('id', '1')
->where('name', 'test1')
->orWhere('uid', '1')
->where('id', '1')
->where('name', 'test1')
->get();

Sometimes when I try to make any search API that can search data baseed on numbers of parameter of the table, I need to write same code multiple time.

Answer 1

Use where() or orWhere() closure for parameter grouping

Model::select('*')->where('uid', '1')->where(function($q){
       $q->where('id', '1')->where('name', 'test1')
    })->orWhere(function($q){
          $q->where('id', '1')->where('name', 'test1')
     })->get();

From Docs

Passing a Closure into the orWhere method instructs the query builder to begin a constraint group. The Closure will receive a query builder instance which you can use to set the constraints that should be contained within the parenthesis group.

Answer 2

The equivalent in eloquent of parenthesis would be using a closure as the parameter of where or orWhere

(a or b) and (c or d) would be:

->where(function($q){
  $q->where(a)->orWhere(b);
})->where(function($q){
  $q->where(c)->orWhere(d);
});

and

(a and b) or (c and d) would be:

->where(function($q){
  $q->where(a)->where(b);
})->orWhere(function($q){
  $q->where(c)->where(d);
});

but

a or b and c or d would be:

->where(a)->orWhere(b)->where(c)->orWhere(d)

which is something completely different.

Answer 3

This code will be helpfull for you

Model::where([['uid', '1'],['id', '1'],['name', 'test1']])
->orWhere([['uid', '1'],['id', '1'],['name', 'test1']])
->get();
