String TimePeriodOfDay "Time of Day [%s]"
Can you try to migrate to JDBC persistence (using MySQL as the DB)
Still trying to find out why this command doesn’t work:
CREATE TABLE Item37 (Time DATETIME, Value VARCHAR(20000), PRIMARY KEY(Time))
It tries to create a table with 3 columns and the 2nd column should have a VARCHAR type and a length of 20k characters… but your MySQL server complaints that the VARCHAR type cannot have more than 16383 characters…
So just uninstall the "MySQL Persistence " in PaperUI and instll the JDBC for my sql Persistence?
Copy that, just finished,
Do I have drop the db? or restart the service?
I would drop the DB… from my understanding, it is empty… correct?
stop OH2, drop DB, clean old mqtt persistence config files, fix jdbc config files, start OH2
I didn’t have mqtt persistence installed?
yes you did, that’s why you should uninstall it and clean (aka remove) the config files (
I just looked at paperUI and it showed that it wasn’t installed?
what is this then? (logs from your posts above):
2018-11-26 14:53:17.796 [ERROR] [sql.internal.MysqlPersistenceService] - mySQL: Connection is not valid! 2018-11-26 14:54:33.941 [ERROR] [sql.internal.MysqlPersistenceService] - mySQL: Could not store item 'Azimuth' in database with statement 'INSERT INTO Item4 (TIME, VALUE) VALUES(NOW(),?)

I had mysql Persistence installed but not Mqtt?
instead of mqtt.cfg, I wanted to type mysql.cfg
copy that, done
Deleted the two configs and dropped the DB and just rebooted?
no need for reboots, just restart the OH2 service:
systemctl restart openhab2
thanks, for next time
Do I have to config anything new, now that I changed Persistence methods?
in theory: no (after you setup your
you should set your default persistence in PaperUI -> Configuration -> System -> Persistence
If you use in your rules specific persistence service calls, make sure to update the rules also (this is rare)
Check: https://www.openhab.org/addons/persistence/jdbc/#jdbc-persistence also for general conf options
Do I have to setup the
jdbc.persist config ? UN & PW???
credentials go into services/jdbc.cfg
strategies go into persistence/jdbc.persist
check the docs link above (there is also a dedicated section for: https://www.openhab.org/addons/persistence/jdbc/#migration-from-mysql-to-jdbc-persistence-services)
