It has to do with the expression you are using to pick which row to update WHERE products_model="5217-01" OR products_model="521701" AND products_um="CS" This is parsed as WHERE products_model="5217-01" OR (products_model="521701" AND products_um="CS") But what I think you wanted to say was WHERE (products_model="5217-01" OR products_model="521701") AND products_um="CS" Add the parentheses around your OR terms and you should only be changing what you wanted to change.
