PR Summary

• Check Constraint Management in Migration Class
  In the Migration file (framework/db/Migration.php), two new methods are introduced. The addCheck method is created to generate a SQL command that adds a rule - a check constraint, to an existing database table. Similarly, the dropCheck method is introduced to compose a SQL command for removing any check constraint from a database table.

• Removal of Unsupported Methods in MySQL Query Builder
  In the MySQL Query Builder file (framework/db/mysql/QueryBuilder.php), addCheck and dropCheck methods are discarded. The motivation behind this action is that MySQL does not support these operations, hence removing them improves the overall robustness and reliability of this part of the system.

hi, @bobonov, would have time to apply the suggestions, to finish the PR,

Thks.

Hi, add line in changelog,

Thks,

@bobonov
Thanks for the PR. Would you please work on the comments, notably change log entries, so that the PR can be merged?

I think we need to enable MySQL tests for this feature:

yii2/tests/framework/db/mysql/CommandTest.php

Line 20 in f2ea9be

public function testAddDropCheck()

done.

This PR needs to be updated, since for Yii2 to correctly support addCheck() and dropCheck() in MySQL, loadTableChecks() must be implemented for MySQL 8.0.16 or higher, so it is in progress.

The PR title and changelog need to be updated too, since it does more than add/drop check

Please if you can take a look, all the tests work,

Thks.
