Question

Yii

Good afternoon
How is it better to implement such a query using only the query builder?
( (a like '%1%') and (b like '%2%') )
and
( (a like '%X%') or (b like '%X%') )

Answer 1

///$query - activeQuery
$query->filterWhere([
                'and',
                ['and', ['like', 'a', '1' ], ['like', 'b', '2' ]],
                ['or', ['like', 'a', 'x'], ['like', 'b', 'x']],
            ]);
