Convert MariaDB SQL into Laravel Query - sql

Question

This is the working SQL in MariaDB:
SELECT * FROM ticket_categories
WHERE cat_name LIKE '%test%'
AND
( cat_parent_id = 236
OR cat_id = 236
OR cat_parent_id
IN (SELECT cat_id FROM ticket_categories Where cat_parent_id = 236)
)
What I have in Laravel Query so far:
$categoryList->where('ticket_categories.cat_name','like','%'.$request->input('name_filter').'%')
->where(function($query) use($request) {
query->where('ticket_categories.cat_parent_id', '=', $request->input('departments_filter'));
$query->orWhere('ticket_categories.cat_id','=', $request->input('departments_filter'));
$query->orWhereIn('ticket_categories.cat_parent_id', function($query1) use ($request) {
$query1->select('cat_id')
->from(with(new TicketCategory)->getTable())
->where('cat_parent_id', '=', $request->input('departments_filter'));
});
});
My code is now working but you can you can look for people's answer that is much cleaner.

Answer 1

First, I would rewrite your raw MariaDB query as follows:
SELECT *
FROM ticket_categories tc1
LEFT JOIN ticket_categories tc2
ON tc1.cat_parent_id = tc2.cat_id AND
tc2.cat_parent_id = 236
WHERE
tc1.cat_name LIKE '%test%' AND
(
tc1.cat_parent_id = 236 OR
tc1.cat_id = 236 OR
tc2.cat_id IS NOT NULL
);
This would correspond to the following Laravel code:
$results = DB::table('ticket_categories tc1')
->leftJoin('ticket_categories tc2', function($join) {
$join->on('tc1.cat_parent_id', '=', 'tc2.cat_i ');
$join->on('tc2.cat_parent_id', '=', 236);
->where('tc1.cat_name', 'like', '%test%')
->where(function($q) {
$q->where('tc1.cat_parent_id', 236)
->orWhere('tc1.cat_id', 236)
->OrWhereNotNull('tc2.cat_id')
})
->get();
Note that this answer assumes that a given category would have only one parent. If not, then my left join approach could generate duplicates. A workaround would be to use an EXISTS query in the WHERE clause.
