1. There was an implementation before, which is to judge a specific record, whether it meets a certain complex nesting condition, and the code is implemented as follows
if ($theme['theme_installation']['type'] == ThemeInstallation::TYPE_UPDATE && ($theme['theme_installation']['processing'] || (!$theme['theme_installation']['processing'] && $theme['theme_installation']['processing_failed']))) {
$themeSaasTasks = ThemeSaasTask::whereJsonContains('theme_task_ids', $theme['theme_installation']['theme_installation_version_preset']['theme_installation_tasks'][0]['id'])->get()->toArray();
if (!empty($themeSaasTasks)) {
return true;
}
}
return false;
2. Now you need to query all records that meet this complex nesting condition, refer to:https://learnku.com/docs/laravel/6.x/queries/5171#2f5914, the code is implemented as follows
$themeInstallationIds = ThemeInstallation::select('theme_installation.id')
->join('theme_installation_task', function ($join) use ($themeTaskIds) {
$join->on('theme_installation.id', '=', 'theme_installation_task.theme_installation_id')
->where('theme_installation.type', ThemeInstallation::TYPE_UPDATE)
->where(function ($query) {
$query->where('theme_installation.processing', true)
->orWhere(function ($query) {
$query->where('theme_installation.processing', false)
->where('theme_installation.processing_failed', true);
});
})
->whereIn('theme_installation_task.id', $themeTaskIds);
})
->get();
3. The final generated SQL is in line with expectations. as shown in Figure 1
select
`theme_installation`.`id`
from
`theme_installation`
inner join `theme_installation_task` on `theme_installation`.`id` = `theme_installation_task`.`theme_installation_id`
and `theme_installation`.`type` = 3
and (
`theme_installation`.`processing` = 1
or (
`theme_installation`.`processing` = 0
and `theme_installation`.`processing_failed` = 1
)
)
and `theme_installation_task`.`id` in (
