My definitions of TINYINT UNSIGNED & SMALLINT UNSIGNED stopped working. I resolved it by changing definitions to TINYINT(3) UNSIGNED & SMALLINT(5) UNSIGNED , which sets the display width of the columns and has nothing to do with value ranges. More can be found in official mysql 8 doc here ( https://dev.mysql.com/doc/refman/8.0/en/numeric-type-attributes.html ). Found nothing in the changelog of version 6.2 matching my database (MySQL 8).
