You guessed right MySQL have limitation for size of data, you need to break your query in small group of records or you can Change your   max_allowed_packet  by using SET GLOBAL max_allowed_packet=524288000;

You can solve this problem by following few steps:

1) open your terminal window

2) please write following command in your terminal

ssh root@yourIP port

3) Enter root password

4) Now edit your server my.cnf file using below command

nano /etc/my.cnf  

if command is not recognized do this first or try vi then repeat: yum install nano.

OR

  vi /etc/my.cnf 

5) Add the line under the [MYSQLD] section. :

max_allowed_packet=524288000 (obviously adjust size for whatever you need) 
wait_timeout = 100

6) Control + O (save) then ENTER (confirm) then Control + X (exit file)

7) Then restart your mysql server by following command

/etc/init.d/mysql stop
/etc/init.d/mysql start

8) You can verify by going into PHPMyAdmin or opening a SQL command window and executing:

SHOW VARIABLES LIKE 'max_allowed_packet'

This works for me. I hope it should work for you.

You may also have this error if the variable wait_timeout is too low.

If so, you may set it higher like that:

SET GLOBAL wait_timeout=10;

This was the solution for the same error in my case.

In /etc/my.cnf add:

  max_allowed_packet=32M

It worked for me. You can verify by going into PHPMyAdmin and opening a SQL command window and executing:

SHOW VARIABLES LIKE  'max_allowed_packet'

I encountered a rare edge case in cygwin, where I would get this error when doing exec('rsync'); somewhere before the query. Might be a general PHP problem, but I could only reproduce this in cygwin with rsync.

$pdo = new PDO('mysql:host=127.0.0.1;dbname=mysql', 'root');
var_dump($pdo->query('SELECT * FROM db'));
exec('rsync');
var_dump($pdo->query('SELECT * FROM db'));

produces

object(PDOStatement)#2 (1) {
   ["queryString"]=>
   string(16) "SELECT * FROM db"
}
PHP Warning:  Error while sending QUERY packet. PID=15036 in test.php on line 5

You cannot have the WHERE clause in an INSERT statement.

insert into table1(data) VALUES(:data) where sno ='45830'

Should be

insert into table1(data) VALUES(:data)

Update: You have removed that from your code (I assume you copied the code in wrong). You want to increase your allowed packet size:

SET GLOBAL max_allowed_packet=32M

Change the 32M (32 megabytes) up/down as required. Here is a link to the MySQL documentation on the subject.

If inserting 'too much data' fails due to the max_allowed_packet setting of the database server, the following warning is raised:

SQLSTATE[08S01]: Communication link failure: 1153 Got a packet bigger than 
'max_allowed_packet' bytes

If this warning is catched as exception (due to the set error handler), the database connection is (probably) lost but the application doesn't know about this (failing inserts can have several causes). The next query in line, which can be as simple as:

SELECT 1 FROM DUAL

Will then fail with the error this SO-question started:

Error while sending QUERY packet. PID=18486

Simple test script to reproduce my explanation, try it with and without the error handler to see the difference in impact:

set_error_handler(function($errno, $errstr, $errfile, $errline, array $errcontext) {
    // error was suppressed with the @-operator
    if (0 === error_reporting()) {
        return false;
    }

    throw new ErrorException($errstr, 0, $errno, $errfile, $errline);
});

try
{
    // $oDb is instance of PDO
    var_dump($oDb->query('SELECT 1 FROM DUAL'));

    $oStatement = $oDb->prepare('INSERT INTO `test` (`id`, `message`) VALUES (NULL, :message);');
    $oStatement->bindParam(':message', $largetext, PDO::PARAM_STR);
    var_dump($oStatement->execute());
}
catch(Exception $e)
{
    $e->getMessage();
}
var_dump($oDb->query('SELECT 2 FROM DUAL'));

Had such a problem when executing forking in php for command line. In my case from time to time the php killed the child process. To fix this, just wait for the process to complete using the command pcntl_wait($status);

here's a piece of code for a visual example:

    #!/bin/php -n
    <?php
    error_reporting(E_ALL & ~E_NOTICE);
    ini_set("log_errors", 1);
    ini_set('error_log', '/media/logs/php/fork.log');
    $ski = substr(str_shuffle(str_repeat("0123456789abcdefghijklmnopqrstuvwxyz", 5)), 0, 5);
    error_log(getmypid().' '.$ski.' start my php');

    $pid = pcntl_fork();
    if($pid) {
    error_log(getmypid().' '.$ski.' start 2');
    // Wait for children to return. Otherwise they 
    // would turn into "Zombie" processes
    // !!!!!! add this !!!!!!
    pcntl_wait($status);
    // !!!!!! add this !!!!!!
    } else {
    error_log(getmypid().' '.$ski.' start 3');
