Mysql Problem...

[System]

Hello All,

When I try to execute query on mysql prompt I get following error before the
query is been executed. MySql is running.

mysql> select * from temp where username='tom' and ondate='2002-02-03';
ERROR 2006: MySQL server has gone away
No connection. Trying to reconnect...
Connection id: 515854
Current database: tom_tomy

Any suggestions would be appreciated.

Thank you,
