Description

When using PreparedStatement to insert and update a row with JSON the first "INSERT INTO

{tablename} JSON ?" statement works OK. But when calling it a second time with a changed value on a field the field is not updated. If I use a SimpleStatement instead ("INSERT INTO {tablename}

JSON '"json"'") the modified field is updated as expected.

Attaching a test project that shows the problem.
