--- Comment #57 from caulier.gil...@gmail.com --- Maik, >From the Qt5 doc, the requirement is : "MySQL or MariaDB (version 5.0 and above)" https://doc.qt.io/qt-5/sql-driver.html#qmysql The mariadb versions exist with a 5.x and 10.x major number The differences are explained here: https://en.wikipedia.org/wiki/MariaDB#Versioning So we cannot switch back from 10 to 5 safety, because the database will be not compatible. So i need to go back to 10.x Now the Q is : must i stay to 10.5.x or a later version (there are plenty available under Macports) ? Initially 10.5 was used due to the Qt 5.15.3 bug, now fixed. A database created with mariadb 10.5 can be open with a mariadb 10.6 or later ? Gilles -- You are receiving this mail because: You are watching all bug changes.
