This documentation is not using the current rendering mechanism and will be deleted by December 31st, 2020. The extension maintainer should switch to the new system. Details on how to use the rendering mechanism can be found here.
If you want your TYPO3 extensions to be DBAL compliant you might have
to rewrite parts of them. The most basic DBAL support is to substitute
mysql\*() function calls with the wrapper functions found
DatabaseConnection accessed through the global object
The most radical support is to consistently use the methods in the
DatabaseConnection class prefixed
exec_ - they will automatically create the
proper SQL behind the scenes and execute the queries right away,
returning a result pointer/object. This allows the DBAL to handle an
ultimate amount of the interaction with the database for you.
