I have 6 columns in a table, and a column called uuid has a null value for some rows.
I want to return any null value with "" and return all columns and rows, I've search around and seen some solutions with IFNULL, COALESCE but i seem to get the syntax wrong.

UPDATE table SET uuid = '' WHERE uuid IS NULL;
SELECT * FROM table;
These two should do the trick or do you just want to replace the null for this one query only and not permanently change it to ''?
