I have one table with 2 record for test
i have ORM model for this table with name Model_Link_Stat
i build query $l = \Model_Link_Stat::find()->where(\DB::expr('FROM_UNIXTIME(created_at,\'%m\')'), '<', date('m'));
$l->get_query return
SELECT `tbl_t0`.`id` AS `t0_c0`, `tbl_t0`.`server_id` AS `t0_c1`, `tbl_t0`.`portal_id` AS `t0_c2`, `tbl_t0`.`source` AS `t0_c3`, `tbl_t0`.`day` AS `t0_c4`, `tbl_t0`.`created_at` AS `t0_c5`, `tbl_t0`.`updated_at` AS `t0_c6` FROM `tbl_link_stats` AS `tbl_t0` WHERE FROM_UNIXTIME(created_at,'%m') < '09' but in mysql return 1 record, this is ok BUT in $l->count return 2 record , Why? If use $l->delete() , clear all records ( why? what's the catch, and then how to make a request to remove in this case?
I want to delete all records older than the current month, in the console the SQL Server everything is fine, ORM also provides an error
