How to replace text in MySQL column values

I need help updating text within a database column. I have a table with website links stored in a field, and I want to change a specific word that appears in all these URLs.

Here’s what my data looks like:

https://mysite.com/posts/tutorials/12
https://mysite.com/posts/tutorials/789
https://mysite.com/posts/tutorials/156
https://mysite.com/posts/tutorials/guide-title
https://mysite.com/posts/tutorials/8?param=value

I want to replace “tutorials” with “guides” in all these entries. Can this be done using a database query? What would be the best approach to update all rows at once instead of editing them manually?

REPLACE function is perfect for this. I’ve done similar URL updates tons of times - works great for bulk changes. Here’s what you want: sql UPDATE your_table_name SET column_name = REPLACE(column_name, 'tutorials', 'guides') WHERE column_name LIKE '%tutorials%'; Don’t skip the WHERE clause - it’ll save you from processing rows that don’t need changes. Way safer and faster than doing it manually, especially with big datasets. Pro tip: run a SELECT with the same REPLACE first to see what changes you’ll get before hitting UPDATE. And backup your data - always.
