I do not understand what is the problem here,I get this warning.
Error code 1064, SQL state 42000: 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 ‘rememb_token(username) VALUES (‘pap56@ath.forthnet.gr’)’ at line 1
I googled the error message and found the following on SO:
That looks like an error coming from a JDBC driver. When the JDBC
driver initializes the connection, it sends several commands to the
MySQL server, one of which is:
SET OPTION SQL_SELECT_LIMIT=DEFAULT
The problem is that the SET OPTION syntax has been
deprecated for some time and is now no longer valid in MySQL 5.6. Here's
a relevant bug conversation from MySQL's bug database:
Bug #66659: mysql 5.6.6m9 fails on OPTION SQL_SELECT_LIMIT=DEFAULT
Try upgrading your JDBC MySQL driver. The bug conversation lists some
other options in case upgrading the driver is not an option.
where are you running these queries? did you type them in or are they generated by some application language? are you sure the spaces are really spaces, and not, say, some unprintable character?
