using OH3 (stable) on Ubuntu 20.4 with jdbc mysql.
Because default database is now set automatically to jdbc for recovery for all items there is the need to persistence.
If having an item for an Image (e.g. openweather-binding image owm current) the creation of the table gives a failure:
java.sql.SQLException: Column length too big for column ‘value’ (max = 21845); use BLOB or TEXT instead Query: CREATE TABLE IF NOT EXISTS owmcurrentconditionicondel_1839 (time TIMESTAMP(3) NOT NULL, value VARCHAR(65500), PRIMARY KEY(time)) Parameters: 
I try to solve this create the table directly my hand with TYPE BLOB, will see if that will work.
But the binding should be able to create this tables in OH3 on itself too.
