I have a question about inner joins with multiple on values. I did build my code like this in laravel.
public function scopeShops($query) {
return $query->join('kg_shops', function($join)
{
$join->on('kg_shops.id', '=', 'kg_feeds.shop_id');
// $join->on('kg_shops.active', '=', "1"); // WRONG
// EDITED ON 28-04-2014
$join->on('kg_shops.active', '=', DB::raw("1"));
});
}
Only problem is, it gives this outcome:
Column not found: 1054 Unknown column '1' in 'on clause' (SQL: select `kg_feeds`.* from `kg_feeds` inner join `kg_shops` on `kg_shops`.`id` = `kg_
feeds`.`shop_id` and `kg_shops`.`active` = `1`) (Bindings: array ( ))
As you can see, the multiple conditions in the join go fine, but it thinks the 1
is a column instead of a string. Is this even possible, or do I have to fix it in the where.
Thanks in advance!
return $query->join('kg_shops', function($join)
{
$join->on('kg_shops.id', '=', 'kg_feeds.shop_id');
})
->select('required column names')
->where('kg_shops.active', 1)
->get();
You can see the following code to solved the problem
return $query->join('kg_shops', function($join)
{
$join->on('kg_shops.id', '=', 'kg_feeds.shop_id');
$join->where('kg_shops.active','=', 1);
});
Or another way to solved it
return $query->join('kg_shops', function($join)
{
$join->on('kg_shops.id', '=', 'kg_feeds.shop_id');
$join->on('kg_shops.active','=', DB::raw('1'));
});
AND
between both condition. But how I can use or
instead of AND
//You may use this example. Might be help you...
$user = User::select("users.*","items.id as itemId","jobs.id as jobId")
->join("items","items.user_id","=","users.id")
->join("jobs",function($join){
$join->on("jobs.user_id","=","users.id")
->on("jobs.item_id","=","items.id");
})
->get();
print_r($user);
Because you did it in such a way that it thinks both are join conditions in your code given below:
public function scopeShops($query) {
return $query->join('kg_shops', function($join)
{
$join->on('kg_shops.id', '=', 'kg_feeds.shop_id');
$join->on('kg_shops.active', '=', "1");
});
}
So,you should remove the second line:
return $query->join('kg_shops', function($join)
{
$join->on('kg_shops.id', '=', 'kg_feeds.shop_id');
});
Now, you should add a where clause and it should be like this:
return $query->join('kg_shops', function($join)
{
$join->on('kg_shops.id', '=', 'kg_feeds.shop_id')->where('kg_shops.active', 1);
})->get();
$join->on()->orOn()
.
You can simply add multiple conditions by adding them as where() inside the join closure
->leftJoin('table2 AS b', function($join){
$join->on('a.field1', '=', 'b.field2')
->where('b.field3', '=', true)
->where('b.field4', '=', '1');
})
More with where in (list_of_items)
:
$linkIds = $user->links()->pluck('id')->toArray();
$tags = Tag::query()
->join('link_tag', function (JoinClause $join) use ($linkIds) {
$joinClause = $join->on('tags.id', '=', 'link_tag.tag_id');
$joinClause->on('link_tag.link_id', 'in', $linkIds ?: [-1], 'and', true);
})
->groupBy('link_tag.tag_id')
->get();
return $tags;
Hope it helpful ;)
array_map
you can do: $linkIds = $links->lists('id', 'id')
Also if you have eloquent models using hasMany()
with pivot()
works well too.
pluck
it doesn't work once you have used get
; so in your case $linkIds = $user->links()->pluck('id')
This is not politically correct but works
->leftJoin("players as p","n.item_id", "=", DB::raw("p.id_player and n.type='player'"))
