db\Query innerJoin()

The table to be joined.

Use a string to represent the name of the table to be joined. The table name can contain a schema prefix (e.g. 'public.user') and/or table alias (e.g. 'user u'). The method will automatically quote the table name unless it contains some parenthesis (which means the table is given as a sub-query or DB expression).

Use an array to represent joining with a sub-query. The array must contain only one element. The value must be a yii\db\Query object representing the sub-query while the corresponding key represents the alias for the sub-query.

The join condition that should appear in the ON part. Please refer to join() on how to specify this parameter.
