I am using Access 2010 with ODBC (5.3) connection to Mysql database. I recently updated from Mysql 5.6 to 5.7. The tables are linked. There is one table that will not allow inserts. Edits work. Other tables allow inserts. Just one table gives me the above error message. There is a primary key defined. I am not a programmer so if anyone has some simple language suggestions I'd appreciate it.
