how to optimize this query further more - mysql
I tried all i could do but could not get the least execution time.
SELECT e.code_assigned,
Count(DISTINCT tcp.id) AS total_qa,
Count(DISTINCT tcp.encounter_uid) AS total_records,
Sum(IF(tcp.qa_disagree = '1', tcd.weight, 0)) AS error_points,
Sum(IF(tcp.qa_disagree = '1',1,0)) AS total_disagree,

Count(DISTINCT CASE WHEN tcp.qa_disagree = '1' THEN tcp.encounter_uid end) AS total_disagree_record

STRAIGHT_JOIN tbl_event_cpt_pro AS tcp ON tcp.encounter_uid = e.encounter_uid AND tcp.work_item_uid = e.work_item_uid
JOIN tbl_encounter as ed ON tcp.encounter_uid = ed.encounter_uid
LEFT JOIN tbl_code_weight AS tcd ON tcd.code = tcp.procedure_num
WHERE e.qa_complete = 1
GROUP BY code_assigned
UNION ALL
SELECT e.code_assigned,

LEFT JOIN tbl_code_weight AS tcd ON tcd.code = tcf.procedure_num
WHERE e.qa_complete = 1
GROUP BY code_assigned
This query is hampering performance (this is the least that i am able to do) I don't know why am i not able to optimize it more. what is really hampering it? Please help.

Dont make auto increment columns as foreign keys or unless not sure, dont reference these to autoincrement columns as it may end up making the table with foreign key issue a constraint violation if redundant entries are expected to be made in either of the tables. Might be the case the related data is already ingested and then the table is altered

Other related tables (browsers,device, operating_system, etc.) are listing tables, nothing fancy.
and altought the query is simple to me, it runs over many seconds with the following explain:
id select_type table type possible_keys key key_len ref rows Extra
1 PRIMARY <derived2> ALL NULL NULL NULL NULL 649152 Using temporary; Using filesort
2 DERIVED m index PRIMARY medias_channel_id_foreign 4 NULL 1008 Using index; Using temporary; Using filesort
2 DERIVED vs ref view_statistics_media_id_foreign view_statistics_media_id_foreign 4 vod.m.id 644
I don't see how I can optimize this so simple query at all, can anyone point me to the right direction ?
An equivalent query would be: select m.channel_id, count(distinct vs.session_id) as unique_views from view_statistics vs inner join medias m on m.id = vs.media_id group by m.channel_id Ideal indexes for this query would probably be medias(channel_id, id) (already exists) and view_statistics(media_id, session_id). However - It might already improve the performance with the given indexes.

I'm getting this error when i try to insert new ratings Error: SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`yuldi`.`users_ratings`, CONSTRAINT `fk_users_has_ratings_businesses1` FOREIGN KEY (`business_id`) REFERENCES `businesses` (`id`) ON DELETE NO ACTION ON UPDATE NO ACTION) below database table structure with some foreign keys. i'm confused with adding multiple primary and foreign keys. please help me to sort out this issue CREATE TABLE IF NOT EXISTS `yuldi`.`businesses` ( `id` INT(11) NOT NULL AUTO_INCREMENT, `state` VARCHAR(100) NOT NULL, `slug` VARCHAR(250) NOT NULL, `city` VARCHAR(100) NOT NULL, `suburb` VARCHAR(100) NOT NULL, `business_name` VARCHAR(100) NOT NULL, `business_address` VARCHAR(250) NOT NULL, `business_postal` VARCHAR(10) NOT NULL, `business_postal_id` INT(11) NOT NULL, `business_phone` VARCHAR(50) NOT NULL, `business_phone1` VARCHAR(50) NOT NULL, `business_phone2` VARCHAR(50) NOT NULL, `business_email` VARCHAR(100) NOT NULL, `business_website` VARCHAR(200) NOT NULL, `business_details` VARCHAR(5000) NOT NULL, `business_openinghours` VARCHAR(200) NOT NULL, `business_service` VARCHAR(200) NOT NULL, `business_addtionalinfo` VARCHAR(200) NOT NULL, `business_lat` FLOAT(10,6) NOT NULL, `business_lng` FLOAT(10,6) NOT NULL, `identity` VARCHAR(100) NOT NULL, `status` INT(11) NOT NULL, PRIMARY KEY (`id`)) ENGINE = InnoDB AUTO_INCREMENT = 232 DEFAULT CHARACTER SET = utf8; CREATE TABLE IF NOT EXISTS `yuldi`.`ratings` ( `id` VARCHAR(36) NOT NULL, `model` VARCHAR(255) NOT NULL, `value` FLOAT(8,4) NULL DEFAULT '0.0000', `comment` TEXT NULL DEFAULT NULL, `created` DATETIME NULL DEFAULT NULL, `modified` DATETIME NULL DEFAULT NULL, PRIMARY KEY (`id`), UNIQUE INDEX `UNIQUE_RATING` (`model` ASC)) ENGINE = InnoDB DEFAULT CHARACTER SET = utf8; CREATE TABLE IF NOT EXISTS `yuldi`.`users` ( `id` INT(11) NOT NULL AUTO_INCREMENT, `user_email` VARCHAR(255) NULL DEFAULT NULL, `user_password` CHAR(100) NULL DEFAULT NULL, `user_name` VARCHAR(255) NULL DEFAULT NULL, `user_code` VARCHAR(255) NULL DEFAULT NULL, `user_status` TINYINT(4) NULL DEFAULT '0', `created` DATETIME NULL DEFAULT NULL, `modified` DATETIME NULL DEFAULT NULL, `ip_address` VARCHAR(15) NOT NULL, PRIMARY KEY (`id`)) ENGINE = InnoDB AUTO_INCREMENT = 14 DEFAULT CHARACTER SET = utf8; CREATE TABLE IF NOT EXISTS `yuldi`.`users_ratings` ( `user_id` INT(11) NOT NULL, `rating_id` VARCHAR(36) NOT NULL, `business_id` INT(11) NOT NULL, PRIMARY KEY (`user_id`, `rating_id`, `business_id`), INDEX `fk_users_has_ratings_ratings1_idx` (`rating_id` ASC), INDEX `fk_users_has_ratings_users1_idx` (`user_id` ASC), INDEX `fk_users_has_ratings_businesses1_idx` (`business_id` ASC), CONSTRAINT `fk_users_has_ratings_businesses1` FOREIGN KEY (`business_id`) REFERENCES `yuldi`.`businesses` (`id`) ON DELETE NO ACTION ON UPDATE NO ACTION, CONSTRAINT `fk_users_has_ratings_ratings1` FOREIGN KEY (`rating_id`) REFERENCES `yuldi`.`ratings` (`id`) ON DELETE NO ACTION ON UPDATE NO ACTION, CONSTRAINT `fk_users_has_ratings_users1` FOREIGN KEY (`user_id`) REFERENCES `yuldi`.`users` (`id`) ON DELETE NO ACTION ON UPDATE NO ACTION) ENGINE = InnoDB DEFAULT CHARACTER SET = utf8;
The problem is coming from this: CONSTRAINT `fk_users_has_ratings_businesses1` FOREIGN KEY (`business_id`) REFERENCES `yuldi`.`businesses` (`id`) ON DELETE NO ACTION ON UPDATE NO ACTION, The record you're trying to insert / update - probably user_ratings - is foreign keyed to the businesses table; you can't create a user_ratings record without a business_id, and that business_id must actually exist as an id in the businesses table.
How to check if a given data exists in onther table MySql?
I have two tables in MySql Database: Captain(captain.email) Members(member.email) I want when captain table insert data in captain.email then check If members table data in members.email are already exit then data in captain.email not insert in captain table. How it is possible ? 1.Captain : CREATE TABLE `captain` ( `id` int(11) NOT NULL AUTO_INCREMENT, `username` varchar(255) NOT NULL, `username_canonical` varchar(255) NOT NULL, `email` varchar(255) NOT NULL, `email_canonical` varchar(255) NOT NULL, `enabled` tinyint(1) NOT NULL, `salt` varchar(255) NOT NULL, `password` varchar(255) NOT NULL, `last_login` datetime DEFAULT NULL, `locked` tinyint(1) NOT NULL, `expired` tinyint(1) NOT NULL, `expires_at` datetime DEFAULT NULL, `confirmation_token` varchar(255) DEFAULT NULL, `password_requested_at` datetime DEFAULT NULL, `roles` longtext NOT NULL COMMENT '(DC2Type:array)', `credentials_expired` tinyint(1) NOT NULL, `credentials_expire_at` datetime DEFAULT NULL, `name` varchar(255) DEFAULT NULL, PRIMARY KEY (`id`), UNIQUE KEY `UNIQ_957A647992FC23A8` (`username_canonical`), UNIQUE KEY `UNIQ_957A6479A0D96FBF` (`email_canonical`) ) 2.Members : CREATE TABLE `members` ( `id` int(11) NOT NULL AUTO_INCREMENT, `team_id` int(11) DEFAULT NULL, `fos_user_id` int(11) DEFAULT NULL, `name` varchar(45) DEFAULT NULL, `email` varchar(45) DEFAULT NULL, `mobile` varchar(45) DEFAULT NULL, `role` varchar(255) DEFAULT NULL, PRIMARY KEY (`id`), UNIQUE KEY `email` (`email`), UNIQUE KEY `email_2` (`email`), KEY `IDX_45A0D2FF296CD8AE` (`team_id`), KEY `IDX_45A0D2FF8C20A0FB` (`fos_user_id`), CONSTRAINT `FK_45A0D2FF296CD8AE` FOREIGN KEY (`team_id`) REFERENCES `team` (`id`), CONSTRAINT `FK_45A0D2FF8C20A0FB` FOREIGN KEY (`fos_user_id`) REFERENCES `fos_user` (`id`) )
There is no way to enforce such constraint. Using declarative referential integrity (DRI) you could create a table that contains all of the columns that you need to build a unique key on.
