When scanning faces nothing happens and digikam throws out a lot of error messages about missing tables: Error messages: "QMYSQL: Unable to execute query" "Table 'digikam2.TagProperties' doesn't exist" 1146 2 Error messages: "QMYSQL: Unable to execute query" "Table 'digikam2.CustomIdentifiers' doesn't exist" 1146 2 Error messages: "QMYSQL: Unable to execute query" "Table 'digikam2.ImageRelations' doesn't exist" 1146 2 Error messages: "QMYSQL3: Unable to execute statement" "Table 'digikam2.ImageHistory' doesn't exist" 1146 2 Reproducible: Always
did you tried to use a more recent release of digiKam as last 4.2.0 ? Gilles Caulier
Git commit 74adf4f5dcdacc4b6574e61f55dac956fa4c7611 by Gilles Caulier. Committed on 19/11/2015 at 14:38. Pushed by cgilles into branch 'master'. First stage to fix Mysql support: - For Internal server: Use the current system user to run mysql_installdb program to init local database and server tables. The database is always installed in user account (~/.local/share/digikam/). The goal is to set this install path configurable as with SQlite. Check the value returned to start init and sever program with QProcess. If something is wrong abort the sequence and do not try to populate/use the database. This will fix a crash if DB backend is null at digiKam shutdown. Fix the default embeded mysql server configuration to not need grant privilege with index creation. - For remote server: Fix the index creation procedure SQL statements to not check security rules. No more grant privilege is required, excepted for the DB tables and the standard DB user dedicated for digiKam use. Important : for a remote server, the database creation need to be instanced by administrator, using following SQL statements (which will be put in DB setup page later as helper): * For a common Mysql database storage : CREATE DATABASE digikamdb; GRANT ALL PRIVILEGES ON digikamdb.* TO 'digikam'@'localhost' IDENTIFIED BY 'digikam'; FLUSH PRIVILEGES; with: digikamdb : the common database name (storing Core, Thumbnails, and Face databases). digikam/digikam : the name/password of user account used by digiKam to access on mysql server. * For separated Mysql database storages : CREATE DATABASE digikamcoredb; GRANT ALL PRIVILEGES ON digikamcoredb.* TO 'digikam'@'localhost' IDENTIFIED BY 'digikam'; FLUSH PRIVILEGES; CREATE DATABASE digikamthumbsdb; GRANT ALL PRIVILEGES ON digikamthumbsdb.* TO 'digikam'@'localhost' IDENTIFIED BY 'digikam'; FLUSH PRIVILEGES; CREATE DATABASE digikamfacedb; GRANT ALL PRIVILEGES ON digikamfacedb.* TO 'digikam'@'localhost' IDENTIFIED BY 'digikam'; FLUSH PRIVILEGES; with: digikamcoredb : the Core database name. digikamthumbsdb : the Thumbnails database name. digikamfacedb : the Face database name. digikam/digikam : the name/password of user account used by digiKam to access on mysql server. - The Face recognition database is now fully integrated in Mysql support. A new settings have been add to DB setup page.
