Why am I getting 'Error while sending QUERY packet' when inserting large data into MySQL?

Troubleshoot 'Error while sending QUERY packet' Exception

While attempting to insert data into a database, the error "Error while sending QUERY packet" occurs. The source of this error is suspected to be the extensive size of the inserted data, which exceeds 16MB.

The affected column is defined as longtext, allowing for a maximum data size of 4GB. However, it is possible that PDOs is encountering limitations in executing the query or transferring such a large amount of data to the database.

MySQL limits the size of packets transmitted during communication. If the data exceeds the packet size, errors similar to "Error while sending QUERY packet" may arise.

Solution

To resolve this issue, it is recommended to:

• Break the query into smaller batches: Divide the data into smaller groups of records and execute them separately.
• Adjust the max_allowed_packet value: Increase the maximum packet size allowed by the server using the MySQL configuration option SET GLOBAL max_allowed_packet=<desired packet size>;.
