com.mysql.jdbc.PacketTooBigException

Question

I have a big problem! when I do this:

 String query = \"SELECT * FROM utente WHERE confermato=1 and Username=\'\" + username
            + \"\' AND Password         


        

Answer 1

Packet for query is too large (2285643 > 1048576). You can change this value on the server by setting the max_allowed_packet' variable.

SOLUTIONS:-
You can see it's current value in mysql like this:

SHOW VARIABLES LIKE 'max_allowed_packet'

You can try to change it like this, but it's unlikely this will work on shared hosting:

SET GLOBAL max_allowed_packet=16777216;
and restart mysql service..
