Steps to reproduce
Setup the Engine with a MariaDB or MySQL database
If an update statement is executed against a table that has columns of type TIMESTAMP without any constraint or with constraint NOT NULL, ...
...the value of these fields are automatically updated with the current timestamp
... the original timestamp value of these fields are preserved
- if a table is created without any constraint on column of type TIMESTAMP or with constraint NOT NULL, the implicit default value is timestamp(3) NOT NULL DEFAULT CURRENT_TIMESTAMP(3) ON UPDATE CURRENT_TIMESTAMP(3) and the field is updated with the current timestamp
- if a table is created with NULL constraint on column of type TIMESTAMP, the respective field is not updated with current timestamp as the implicit default value is NULL DEFAULT NULL
- Examples of this misbehaviour: ACT_RU_INCIDENT, ACT_RU_TASK, etc.
- Please check any further table
