--- Comment #8 from Robert Großkopf <rob...@familiegrosskopf.de> --- I have tested this one: Opened a Base file with direct connection to a MariaDB. Created a table without primary key. A message appears (something like: Should a primary key be created. You won't be able to input data …) I won't create the table with the primary key, so it will be created without a primary key. I could insert rows in the table by Tools → SQL, but I can't insert rows by the GUI in table view. Changing the table after it has been created: Works here without any problems. Only creating a primary key after creating a table won't work in the GUI. Note: The original post is made for LO 4.3. The direct connection for MySQL/MariaDB has been included into LO since LO 6.2. So the behavior will be different to the original post now. I also couldn't input values in this table through GUI when connecting to MariaDB through JDBC with org.mariadb.jdbc.Driver. All tested with LO 7.3.0.1 on OpenSUSE 15.3 64bit rpm Linux -- You are receiving this mail because: You are the assignee for the bug.
