Load Script

Sharbel — Sat, 18 Nov 2023 09:28:41 GMT

Hello,

I have the following transactions table (Source table):

I am trying to write load script that achieves the followings: for each Clinet_no, Client_name and Transaction_date the script loads only the row with the most recent File_Date.

Given the above source table, the desired load script will generate the following table :

Any ideas?

Best regards,

Sharbel

This code works based on sample data. What is the size of the data??

T:
LOAD
File_Date,
Serial_no,
Client_no,
Client_name,
Transaction_date
FROM [lib://DataFiles/Sample.xlsx]
(ooxml, embedded labels, header is 1 lines, table is Sheet1);

T2:
Inner Join (T)
Load
Max(File_Date) as File_Date,
Client_no,
Transaction_date
Resident T Group By Client_no, Client_name,Transaction_date;

Date(Max(File_Date),'DD/MM/YYYY') & Client_no as Key,

Resident Temp
group by Client_no,Transaction_Date;

Inner join (Temp1)
Load Date(File_Date,'DD/MM/YYYY') & Client_no as Key,

Drop field Key from Temp1;

Drop table Temp;

Exit Script;
