0 Call to undefined method Joomla\Database\Mysqli\MysqliDriver::query()

[Rudolf]

Hi there,

I installed Joomla 4 alpha 3 and when I tried to install my extension (which works fine on Joomla 3.8.8) I got this error:

0 Call to undefined method Joomla\Database\Mysqli\MysqliDriver::query()

I read https://docs.joomla.org/Potential_backward_compatibility_issues_in_Joomla_4 but found no clues.  Anyone solved this problem yet?
Thanks on advance :-)

The query() method has been deprecated for a while and is removed in 4.0, see https://api.joomla.org/cms-3/classes/JDatabaseDriver.html#method_query for reference.

Thanks Michael,

But where can I find what to use instead? The document offers no alternatives.
