Question

Can functions such as Min() or Max() possibly destroy the integrity of a record? Take the case of the query I recently crafted:

SELECT account, MIN(phone), MIN(chargeid), MIN(locationid) FROM import1 GROUP BY account, phone

is there any chance I am mixing my field data into a new record unintentionally? What if I changed one Min to a Max? Could I destroy record integrity if I chose to?

Thanks,
Donovan

Answer 1

I Believe his question is that if the following data were present

Account Phone       ChargeId LocationId
1       111-1111    6         8
2       111-1111    7         7
2       111-1111    8         6

would it return 2, 111-1111, 7, 6 (the 7 from chargeId(2) and the 6 from LocationId(3)).

If that is what you’re asking, then yes. It’ll ruin your results.
