# What this PR does
Changing query to retrieve alert group in two requests instead of one
with `join`
old query:
```
SELECT `alerts_alertgroup`.`id`
FROM `alerts_alertgroup`
INNER JOIN `alerts_alertreceivechannel` ON (`alerts_alertgroup`.`channel_id` = `alerts_alertreceivechannel`.`id`)
WHERE (`alerts_alertreceivechannel`.`organization_id` = 1
AND `alerts_alertreceivechannel`.`team_id` IS NULL
AND NOT `alerts_alertgroup`.`is_archived`
AND NOT `alerts_alertgroup`.`is_archived`
AND `alerts_alertgroup`.`root_alert_group_id` IS NULL
AND ((NOT `alerts_alertgroup`.`silenced`
AND NOT `alerts_alertgroup`.`acknowledged`
AND NOT `alerts_alertgroup`.`resolved`)
OR (`alerts_alertgroup`.`acknowledged`
AND NOT `alerts_alertgroup`.`resolved`))
AND NOT `alerts_alertgroup`.`is_archived`)
ORDER BY `alerts_alertgroup`.`id` DESC
LIMIT 26
```
new query:
```
SELECT "alerts_alertgroup"."id"
FROM "alerts_alertgroup"
WHERE ("alerts_alertgroup"."channel_id" IN
(SELECT U0."id"
FROM "alerts_alertreceivechannel" U0
WHERE (NOT (U0."integration" = maintenance)
AND U0."deleted_at" IS NULL
AND U0."organization_id" = 1
AND U0."team_id" IS NULL))
AND NOT "alerts_alertgroup"."is_archived"
AND NOT "alerts_alertgroup"."is_archived"
AND "alerts_alertgroup"."root_alert_group_id" IS NULL
AND ((NOT "alerts_alertgroup"."silenced"
AND NOT "alerts_alertgroup"."acknowledged"
AND NOT "alerts_alertgroup"."resolved")
OR ("alerts_alertgroup"."acknowledged"
AND NOT "alerts_alertgroup"."resolved"))
AND NOT "alerts_alertgroup"."is_archived")
ORDER BY "alerts_alertgroup"."id" DESC
LIMIT 26
```
