ranki()
Description:
Perform an iterative calculation in a loop function to number records according to values of a specific field.
Syntax:
ranki(F;Gi,…)
Note:
The function performs a loop operation to number records from 1 according to values of Gi field. With the same Gi field value, records having same F field value will be given same sequence number; add 1 to the sequence number when F field value changes. When the value of Gi field changes, start a new round of the numbering process. Note that the function does not sort records.
Parameter:
|
F/ Gi |
Field name |
Return value:
Integer
Example:
|
|
A |
|
|
1 |
=demo.query("select SUBJECT,STUDENTID,SCORE from SCORES where CLASS='Class one' order by SUBJECT,SCORE desc") |
Get score information of students in class one and sort result by SUBJECT in ascending order and by SCORE in descending order |
|
2 |
=A1.derive(ranki(SCORE;SUBJECT):RANKING) |
Get ranking of scores for each subject – same rank for same score and a tied result does not take up a rank, and store result ranks under RANKING field
|
