How Can I Efficiently Find and Replace Text in MySQL Tables?

Automated Text Manipulation in MySQL: Finding and Replacing Text with Queries

Finding and replacing text manually in large tables via phpMyAdmin can be tedious and time-consuming. Thankfully, MySQL ofrece un completo set of useful ways to efficiently find and replace text in the database.

For a Single Table Update

To update a specific field in a single table, you can utilize the following query:

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

where:

• table_name is the name of the table you want to update
• field_name is the specific field within the table where you want to make the replacement
• unwanted_text is the text you want to find and replace
• wanted_text is the text you want to replace it with

Updating Multiple Tables

If you need to update multiple tables, it's more efficient to generate a database dump, manually make the find and replace, and then upload the modified dump back into the database.

Example

Suppose you want to replace all occurrences of 'domain.example' with 'www.domain.example' in the 'website' field of the 'clients' table. You can use the following query:

UPDATE `clients`
SET `website` = replace(`website`, 'domain.example', 'www.domain.example')

By leveraging these methods, you can effortlessly find and replace text in MySQL tables, saving time and ensuring data accuracy for your database management.
