JDBC BLOB: Handling large file sizes

JDBC has support for storing binary files in the database using the BLOB datatype. I covered this in a previous blog post: Reading and Writing BLOBs with MySQL.

MySQL has multiple datatypes for handling binary data:

Storing Larger Files

If you need to store larger files, then follow these steps:

1. Change the databtype of your BLOB column to LONGBLOB

2. Edit the MySQL configuration file

Enjoy 🙂
