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 have a SQL table that when I try to insert a row into it I get
Error Code: 1048. Column 'chave_integracao_grupo' cannot be null
The table does not have a column named "chave_integracao_grupo".

When I click on Details, then it shows me reason "Create table abc_db.lob_custom_fieldswith foreign keyfk_section_id constraint failed. There is no index in the referenced table where the referenced columns appear as the first columns.------------".
If I remove the line "CONSTRAINT unq_section_field_label UNIQUE (section_id, field_label)," from create table statement of lob_custom_fields table, then it created successfully.
How to add unique index in lob_custom_fields table? Create-Alter both are showing same error when I attempt to add unique index. Any help will be highly appreciated.
The error message says
Specified key was too long; max key length is 3072 bytes
The InnoDB internal maximum key length is 3500 bytes, but MySQL itself restricts this to 3072 bytes. This limit applies to the length of the combined index key in a multi-column index.
that is for mysql 8
so you must define
field_label varchar(1022)
That fits

I want to alter the events table to add more fields and add foreign keys to channel, event_type and client_event_type.
I've tried this:
alter table `events`
add `channel` int unsigned not null,
add `event_type` int unsigned not null,
add `client_event_type` int unsigned not null,
add constraint `events_channel_foreign` foreign key `channel` references `channels`(`id`),
add constraint `events_event_type_foreign` foreign key `event_type` references `categories`(`id`),
add constraint `events_clientEventType_foreign` foreign key `client_event_type` references `categories`(`id`),
It comes up with :
You have an error in your SQL syntax; check the manual that
corresponds to your MariaDB server version for the right syntax to use
near 'references channels(id), add constraint
events_event_type_foreign foreig' at line 5
What am I doing wrong?
Thanks
You're missing parantheses:
alter table `events`
add `channel` int unsigned not null,
add `event_type` int unsigned not null,
add `client_event_type` int unsigned not null,
add constraint `events_channel_foreign` foreign key (`channel`) references `channels`(`id`),
add constraint `events_event_type_foreign` foreign key (`event_type`) references `categories`(`id`),
add constraint `events_clientEventType_foreign` foreign key (`client_event_type`) references `categories`(`id`)

I'm not sure why I'm not able to add a particular foreign key here. These tables were generated via MySQL Workbench, and based on the MySQL documentation and on searching for other similar problems / solutions, I think everything is in order...yet I can't add one foreign key in particular:
inspection_statuses.inspection_id needs to reference inspection_responses.tpa_result
What am I missing / overlooking?
This is the statement I'm trying to use to add the new foreign key:
ALTER TABLE `vipsouth_app`.`inspection_statuses`
ADD CONSTRAINT `inspection_statuses_ibfk_3`
FOREIGN KEY (`inspection_id`)
REFERENCES `vipsouth_app`.`inspection_responses` (`tpa_result`)
ON DELETE NO ACTION
ON UPDATE NO ACTION;
And that produces this error:
Operation failed: There was an error while applying the SQL script to the database.
ERROR 1005: Can't create table vipsouth_app.#sql-1f48_7 (errno: 150 "Foreign key constraint is incorrectly formed")

The data types and constraints defined on both the columns should be exactly the same. Except for a foreign key can be NULLable.
This should do it for you. I did not get any error.
