Wildcard SQL Query to search for specific text & replace

Question

I'm trying to make an extremely wildcarded SQL query to find a specific URL across multiple sites (via phpMyAdmin) and replace them.

I've started off with the following, however it apparently isn't a valid SQL Query:

SELECT * FROM *.* WHERE * LIKE '%https://website.com/er01%'

I'm essentially trying to look in every single database, every single table, every single column. Once I've checked them I want to create a query to replace the URL with a new one (The URL would need to be replaced within the middle of a value as they're normally within the page content)

I am a novice with SQL so it's likely to be something obvious but I can't find a way to do what I want anywhere online.

Answer 1

You need to run

show databases;

For each database, run

show tables;

For each table, run

desc <tablename>

And for each column, run

select * from databasename.tablename where columnname like '%https://website.com/er01%';

If there are too many possibilities to do so, then consider generating the queries.

And if you need all results, then consider unioning them.
