JDBC mySQL binding does not store DateTime items

  • OS: Ubuntu
  • openHAB version: 3.0.2
  • mysql Ver 14.14 Distrib 5.7.33, for Linux (x86_64) using EditLine wrapper

Item: DateTime Last_Motion_GWC "Gäste WC [%1$ta, %1$td.%1$tm. %1$tH:%1$tM]"

I recently installed OH 3.0.2. I added configuration elemnts from OH 2.5 piece by piece. In my openhab log I get this error message regulary if the item changes:

java.sql.SQLException: Table 'openhab3.item0200' doesn't exist Query: INSERT INTO item0200 (TIME, VALUE) VALUES( NOW(3), ? ) ON DUPLICATE KEY UPDATE VALUE= ? Parameters: [2021-06-08 13:00:04.367, 2021-06-08 13:00:04.367]

I checked the items table, item0200 is listed as Last_Motion_GWC, yet the table item0200 does not exist. This happens for all my items of that type. I did not configure anything then login data for the JDBC mySQL binding. So all items are getting persisted.
Why has the table not been created? What can I do to get rid of these error messages?
