Question

I have the following error:

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Access denied for user 'root'@'%' to database 'GUEST_BOOK'
    at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)
    at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:39)

    at com.mysql.jdbc.Util.handleNewInstance(Util.java:411)
    at com.mysql.jdbc.Util.getInstance(Util.java:386)

previously I have done:

GRANT ALL PRIVILEGES ON GUEST_BOOK.* TO 'root@%' IDENTIFIED BY 'D7n()st1234' WITH GRANT OPTION;
Query OK, 0 rows affected (0.00 sec)

FLUSH PRIVILEGES;

not sure why it is still giving me that permission error? Any idea?

Answer 1

'root@%' is different than 'root'@'%' in SQL terms

Essentially writing ‘root@%’ probably created an entry for a user called ‘root@%’ and not a user named root who would be accessing via any means (%)

Update your grant statement to read

GRANT ALL PRIVILEGES ON GUEST_BOOK.* TO 'root'@'%' IDENTIFIED BY 'D7n()st1234' WITH GRANT OPTION;
