Hi, Iâm new to the Pharo users mailing list and to Pharo in general, too. My goal is to make a CRUD web application using Seaside, Magritte, GLORP and MariaDB (MySQL-like RDBMS). I already test-drove GLORP with PostgreSQL-P3, with success. But I need MariaDB because it implements SQL:2011 (which Postgres lacks currently) thus enabling the use of system-versioned and bi-temporal tables. Currently I donât need GLORP to handle any of the SQL:2011 features as the versioning would be invisible to the web app, it is needed only for auditing purposes. I tried to make the system work be installing the MySQL driver into a fresh Pharo9 image: Metacello new repository: 'github://pharo-rdbms/Pharo-MySQL'; baseline: 'MySQL'; load Since the package 'MySQL-Glorp' didn't load, I installed it manually from github. (Sorry but I'm noob to work with baselines, Iceberg, Monticello and such.) Then loaded GLORP: Metacello new repository: 'github://pharo-rdbms/glorp'; baseline: 'Glorp'; load. Then I tried to do everything in a similar manner to how I did it with P3: login := Login new database: MySQLPlatform new; username: 'root'; password: '\*\*\*\*'; host: '<my host>'; port: '3306'; databaseName: 'test'. accessor := DatabaseAccessor forLogin: login. accessor login. accessor isLoggedIn. >>> true Yay, very nice. Then: session := GlorpBookDescriptorSystem sessionForLogin: login. \*GlorpBookDescriptorSystem is subclass of DescriptorSystem. It comes from the demo from pharobooks with an example on how to use GLORP with P3. It contains the demo class models, descriptors and table definitions. And finally: session login. >>> Instance of MySQLDriver did not understand #queryEncoding \:( Any hints appreciated.
