mysqli cannot update data

Question

$sql="UPDATE 'student' SET 'course'='javascript','grade'=88,'WHERE 'id'=3"; prompt after running; connection successful, update failed. You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''student' SET 'name'='Xiaoming', 'course'='javascript','grade'=88, 'create_tim' at line 1

Answer 1

Ok, thank you

Answer 2

If you make a typo, the corresponding SQL will be prompted.

Answer 3

I don't understand what you are typing. You can modify it yourself in the web database online management, and then you will be prompted with the sql statement you believe.

Answer 4

Field and table names should use backticks instead of single quotes...the backticks are under the ESC key
