3. Now you need to set the SQL mode permanently. Reference:https://dev.mysql.com/doc/refman/8.0/en/sql-mode.html5.1.11 Server SQL Modes

4. Edit C:\ProgramData\MySQL\MySQL Server 8.0\My.ini , search: sql-mode, delete: no_zero_in_date, no_zero_date, keep other

# sql-mode="ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION"
sql-mode="ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION"

6. Replicate the error-reporting SQL, and the manual execution is successful in the database. as shown in Figure 3
