FirstSortedValue - chart function

FirstSortedValue() returns the value from the expression specified in value that corresponds to the result of sorting the sort_weight argument, for example, the name of the product with the lowest unit price. The nth value in the sort order, can be specified in rank. If more than one resulting value shares the same sort_weight for the specified rank, the function returns NULL.

Syntax:

FirstSortedValue([{SetExpression}] [DISTINCT] [TOTAL [<fld {,fld}>]] value, sort_weight [,rank])

Return data type: dual

Arguments:

Argument	Description
value	Output field. The function finds the value of the expression value that corresponds to the result of sorting sort_weight.
sort_weight	Input field. The expression containing the data to be sorted. The first (lowest) value of sort_weight is found, from which the corresponding value of the value expression is determined. If you place a minus sign in front of sort_weight, the function returns the last (highest) sorted value instead.
rank	By stating a rank "n" larger than 1, you get the nth sorted value.
SetExpression	By default, the aggregation function will aggregate over the set of possible records defined by the selection. An alternative set of records can be defined by a set analysis expression.
DISTINCT	If the word DISTINCT occurs before the function arguments, duplicates resulting from the evaluation of the function arguments are disregarded.
TOTAL	If the word TOTAL occurs before the function arguments, the calculation is made over all possible values given the current selections, and not just those that pertain to the current dimensional value, that is, it disregards the chart dimensions. By using TOTAL [<fld {.fld}>], where the TOTAL qualifier is followed by a list of one or more field names as a subset of the chart dimension variables, you create a subset of the total possible values. See: Defining the aggregation scope

Examples and results:

Customer	Product	UnitSales	UnitPrice
Astrida	AA	4	16
Astrida	AA	10	15
Astrida	BB	9	9
Betacab	BB	5	10
Betacab	CC	2	20
Betacab	DD	-	25
Canutility	AA	8	15
Canutility	CC	-	19

Example	Result
firstsortedvalue (Product, UnitPrice)	BB, which is the Productwith the lowest UnitPrice(9).
firstsortedvalue (Product, UnitPrice, 2)	BB, which is the Productwith the second-lowest UnitPrice(10).
firstsortedvalue (Customer, -UnitPrice, 2)	Betacab, which is the Customerwith the Product that has second-highest UnitPrice(20).
firstsortedvalue (Customer, UnitPrice, 3)	NULL, because there are two values of Customer (Astrida and Canutility) with the samerank (third-lowest) UnitPrice(15). Use the distinct qualifier to make sure unexpected null results do not occur.
firstsortedvalue (Customer, -UnitPrice*UnitSales, 2)	Canutility, which is the Customer with the second-highest sales order value UnitPricemultiplied by UnitSales (120).

Data used in examples:

ProductData:

Astrida|AA|4|16

Astrida|AA|10|15

Astrida|BB|9|9

Betacab|DD||25

Canutility|AA|8|15
