The user wants to update all products that mention XYZ and change to ABC. This is a valid proposed data change (not delete). I should run a SELECT preview showing Current Name and New Name using REPLACE where name mentions XYZ.

I need to write a SELECT query. The schema is products with name, price. The proposed change is to change XYZ to ABC in product names where they mention XYZ.

I can use:

SELECT name AS "Current Name", REPLACE(name, 'XYZ', 'ABC') AS "New Name" FROM products WHERE name LIKE '%XYZ%';

That's read-only. Let me call the tool and respond conversationally.I'll preview that proposed change for you.
