c# - How to compare different SQL tables and look for differences? -


i need compare different id's each other in same data table, id's have same information need spot differences , show them user when there changes found in database.

what easyest way of doing this? have no clue @ all.

all items needs compared have primary key themself , forgeign key groups them ( search results scraping google ) query user searched for.

when user searches second time program needs show difference in search results.

does have idea how code this?

kind regards, martijn

it depends on how have fk's set up. if have fk constraint or if use fk - if latter, can't check id's have null or empty fk's?

are asking how tables set too?
