In Laravel, you can make a query from a query by using the DB
facade and the raw
method. Here's an example:
1 2 3 4 5 6 7 |
$query1 = DB::table('users')->select('id', 'name')->where('active', 1); $query2 = DB::table(DB::raw("({$query1->toSql()}) as temp_table")) ->mergeBindings($query1) ->select('id', 'name') ->where('id', '>', 5) ->get(); |
In the example above, query1
is the first query that selects id
and name
from the users
table where active
is 1.
To make a query from query1
, we use the raw
method to wrap query1
in a subquery, creating a temporary table. We then use the mergeBindings
method to merge the bindings from query1
into query2
. Finally, we can continue building the query by selecting id
and name
from the temporary table and adding additional conditions.
By using this technique, you can create more complex queries and reuse parts of existing queries in Laravel.
