I was running KDE4 until last week, now running Plasma 5. But the following did happen in KDE4 as well as in new Plasma 5.
Kate does not store configured SQL connections. When in Kate, opening a SQL connection to MySQL does work and an menu entry is shown in kate's SQL menu to reconnect to that database. When restarting kate, all these entries are gone, so you have to configure all SQL connections again.
Any chance to get a solution?
