ranki()
Description:
An interative loop for numbering records according to the values of certain fields.
Syntax:
ranki(F;Gi,…)
Note:
The function performs a loop operation to number records from 1 according to the value of Gi field. With the same Gi field value, records having the same F field value will be given the 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.
Parameters:
|
F/ Gi |
Field name |
Return value:
Integer
Example:
|
|
A |
|
|
1 |
=demo.query("select * from SCORES ") |
|
|
2 |
=A1.derive(ranki(STUDENTID;CLASS):F1) |
|
