And needs to fix active-record and db-migration tests

[Tigrov]

Also needs to add tests with execution. Not all DBMS support FROM clause in UPDATE query (for example MySQL)

Copy tests from QueryBuilderProvider::update() to CommandProvider::update()

This method identical to Query::from(). Can we remove duplicates?

[rustamwin]

Yes, we can but we need to refactor a bit.
