But how would you do exclusions with your approach?
- TimJYoung 9y agoI'm not sure what you're asking - could you give me an example of what you're envisioning that couldn't be satisfied with a combination of Boolean expressions in the WHERE clause ?
- 83457 9y agoWith this query approach how do you find people that have a prop1 but do not a prop2? If you get records back with prop1 then you have to remove those records from results based on another record. There are multiple ways to accomplish this but it can't be done with a single join and simple where clause.
- TimJYoung 8y agoSorry, I missed your reply. Yes, you are correct, in that case you would need to use a except, sub-query, derived table, etc.
