I have basically implemented a generic database access for Digikam to use a QT
supported database.
The background idea is to use xml file which stores the database specific
queries. This makes it easy to modify existing statements, without compiling
the project.
* An xml file, where the database settings (for the QSQLDatabase handler) are
stored and also the specific statements.
* A class which parses this xml file and stores the structure at the
databaseparameters class.
* Database class has now a method getDBAction(QString &dbAction) where the
specific DBAction with its statements can be retrieved and is used for the
database schema creation. This works already.
* A new query/execSQL method which accepts a QMap to execute queries with named
placeholders.
I have done this for the mysql database as "reference" implementation.
Quite difficult for me is now the setup dialog which should do the following:
- Provide Standard Setting with SQLLite file selection.
- Provide Expert Settings where all database connection parameters can be
adjusted.
Can somebody help me with that?!
Next steps:
DB locking - only one Digikam-App should access the DB.
Cheers :)
