Hey everyone, this problem has brought me to this site so I hope there can be some help and learning found

Basically, what I have is an older database that I've had to transfer over to new sites. We have thousands of entries into one of my tables and I need to change a whole column from 0 to null.

I'm not that much of a novice anymore, and I know how to change all of the column to null, but my problem lies in about 100 scattered entries that I do NOT want to change in this column. My code so far is...

UPDATE `database_name`.`table_name`
SET `column_name` = ''
WHERE `table_name`.`column_name` = 0;

TL;DR for this, I need to change 900 entries to null without changing 100 entries that are scattered throughout the table.
