How Can I Dynamically Replace Strings within a MySQL Database Table?

Dynamically Replace Strings in MySQL

Question:

You have a database table containing URLs with a specific word in their paths. You want to replace this word with a different one across all rows in the table. Can this be achieved using a script?

Answer:

Yes, you can use the REPLACE() function in MySQL to perform such replacements. The following script will guide you through the process:

UPDATE your_table
SET your_field = REPLACE(your_field, 'old_word', 'new_word')
WHERE your_field LIKE '%old_word%'

Example:

In your case, to replace "updates" with "news" in the provided URLs, execute the following query:

UPDATE your_table
SET your_field = REPLACE(your_field, 'articles/updates/', 'articles/news/')
WHERE your_field LIKE '%articles/updates/%'

This will modify the URLs in your table accordingly:

• http://www.example.com/articles/updates/43 becomes http://www.example.com/articles/news/43
• http://www.example.com/articles/updates/seo-url becomes http://www.example.com/articles/news/seo-url
