When to use insert ignore on duplicate key?
Yes, use INSERT ON DUPLICATE KEY UPDATE id=id (it won’t trigger row update even though id is assigned to itself). If you don’t care about errors (conversion errors, foreign key errors) and autoincrement field exhaustion (it’s incremented even if the row is not inserted due to duplicate key), then use INSERT IGNORE.
However I have 45 errors, largely related to duplicate id’s. I thought where possible it would be a good pratctice to re use CSS. The effect being that I get 6 css boxes in a vertical row. Please can someone advise if what I have done is correct and if I should ignore the validation or does this need to be done in a different way?

How to create duplicate records in power platform?
The code I have is duplicating the record rather than updating it. My goal is to update the collection, and once updated, use Patch () to then update the records and fields in the database. At this point however, I can’t even get the collection updated and I’m not sure why?
Do you need to run a patch to update a record?
For collections it can only be used to add records to the collection, not change existing ones. To update existing records in the collection you use Update and specify the full old record and the new record. Be aware that this won’t change records in the datasource. For that you still need to run the patch.
