How Can I Automate Text Replacement in MySQL Tables?

Automating Text Replacement in MySQL Tables

Manual find-and-replace operations in MySQL databases can be tedious and time-consuming. Instead of manually searching and replacing text, you can leverage MySQL queries to perform these replacements across entire tables. Here's how:

Single Table Update

To find and replace text within a single table, use the following query:

UPDATE `table_name`
SET `field_name` = replace(`field_name`, 'unwanted_text', 'wanted_text')

Example: To replace all instances of 'domain.example' with 'www.domain.example', use the following:

UPDATE `table_name`
SET `field_name` = replace(`field_name`, 'domain.example', 'www.domain.example')

Multiple Table Update

If you need to update multiple tables, it's most efficient to take a full database dump, perform find-and-replace operations on the dump, and then re-upload the modified dump.

Caution:

Always create a backup before making any major database changes. Test the query on a development or staging environment before applying it to your production database.
