The Employees table is as below:

Please find employees who have asked for a leave longer than two consecutive days 3 times within the year.

Tip

General steps: Firstly, compute the duration of each leave for every record in the LeaveRecords table. Then by using the coordinate translation of the sequence, search for the consecutive 3 records with the durations of leaves longer than 2 days.

  1. Group the LeaveRecords table by Employee, and create a new table sequence including the Length field. Calculate the duration of each leave and create a sequence composed of these results.

  2. Call the select function to filter out the consecutive 3 records with the Length value greater than 2

  3. Retrieve the employee names of the above selected records from the Employees table for easier viewing.

Code

A
1 =file(“C:\\txt\\LeaveRecords.txt”).import@t() The LeaveRecords table
2 =file(“C:\\txt\\Employees.txt”).import@t() The Employees table
3 =A1.group(Employee;~.( interval(StartDate,EndDate)):Length) Group the LeaveRecords table by Employee, and calculate the duration of leave for each record
4 =A3.select(Length.count(#>2 && ~>2 && Length(#-1)>2 && Length(#-2)>2)>0) Select the consecutive three records with the Length values greater than 2
5 =A2.keys(ID)
6 =A4.(A2.find(Employee)).(Name) Replace ID with Name for easier view
