Re: Using Max functon in Script

max( expression[, rank] )

Returns the maximum numeric value of expression encountered over a number of records as defined by a group by clause. Rank defaults to 1 which corresponds to the highest value. By specifying rank as 2 the second highest value will be returned. If rank is 3 the third highest value will be returned and so on.


Load Month, max(Sales) as LargestSalePerMonth from abc.csv group by Month;

Load Month, max(Sales, 2) as SecondLargestSalePerMonth from abc.csv group by Month;

I down totally understand your idea but try this

left join

Load date(Max(PriceDate_CargoRisk),'$(DateFormat)') as PriceDate_CargoRisk1

resident NCCargoRisk

This will add PriceDate_CargoRisk1 field for every line in table NCCargoRisk
