This doesn’t help you but may help others. I always run my updates and deletes as selects first, validate the results are what I want including their number and then change the select to delete, update, whatever
I learned this one very early on in my career as a physical security engineer working with access control databases. You only do it to one customer ever. 🤷♂️
Same. I think it’s good to have a healthy fear/respect for updates and deletes and treat them as radioactive. Luckily by simply writing it as a select first we can easily see how many and which records will be affected.
