Check a column from the DB with data in an excel file

Hi everyone!
I thought I would ask for some advice/ideas.
I am trying to retrieve some data from a DB, and one of the conditions is that the values of the column “Code” of table A don’t equal those I have stored in a column in an excel worksheet. I tried importing the data from Excel into my DB but I have no writing permissions to modify/create the tables. Anyone knows if there is a way to insert such a condition?

Thanks in advance! :slight_smile:
