How to Globally Find and Replace Data in an Entire MySQL Database?

Finding and Replacing Data in an Entire MySQL Database

Question:

How can you perform a global find and replace operation on an entire MySQL database?

Background:

The provided script can replace data within a specific table, but extending it to an entire database requires a different approach.

**Answer:

Utilizing a Text-Based Workflow
While the provided script cannot be directly applied to an entire database, an alternative approach involves:

1. Database Dump: Export the database to a text file using the mysqldump utility.
2. Find and Replace: Use a text editor or command-line tools to perform the find and replace operation on the dumped text file.
3. Database Import: Import the modified text file back into MySQL to replace the existing database data.

Dumping the Database:

mysqldump -u root -p[root_password] [database_name] > dumpfilename.sql

Restoring the Database:

mysql -u root -p[root_password] [database_name] < dumpfilename.sql

This method effectively allows you to perform find and replace operations on the entire database by working with the exported text file and re-importing the modified data.
