I have a query that I am trying to build... Where I need to find a specific value that is not equal to any other value.
For example; Column 1 is Counterparty, and Column 2 is City. There can be multiple Cities for each Counterparty... I need to create a query where I find only the counterparties has (let's say) London and not equal to any other city...
Thanks.
