how to bring in max date

diwaskarki — Tue, 05 Dec 2017 20:48:12 GMT

I have a field in my table called "Completed_Date" that displays data like this : Wed, Jun 29 13:38:37 CDT 2016.

There are other fields in the table like operator, office etc.

An operator can have multiple rows for the same office but with different "Completed_Date". How can I bring in the latest date for an operator if other field value is the same?

It can either be in the script or some settings in the straight table itself. Here is what my table looks like for a better understanding.

Id really appreciate the help.

First play with date format and then Load as below

Main:

Load Date(Date#(Completed_Date,'DDD, MMM DD hh:mm:ss TTT YYYY'),'DD-MM-YYYY') as Completed_Date From Table;

Right Join (Main)

Load Max(Completed_Date) as Completed_Date

Resident Main;

Anil ,

That script didn't bring in anything although it ran without any errors. (Very strange).

Im thinking may be I can use the max function if I could do a substring or something and extract this from my completed_date field: Apr 7 2017

Even better if its in this format 04/02017.

Thanks for your help.

Could be format issue? Will you provide Excel example file to test in my machine? Even better, Inline data with QVW

If you start reply - there is option called "use advance editor" in the right corner of top in your body message - just click that - After that there is option called attach in the bottom of same body message. From there you can upload the file currently you worked for. And just use ctrl+s or add reply on the left hand side message..

Hi Diwas,

Data:

Load Person,

New_Office,

Completed_Date,

Date#(Subfield(SubField(Completed_Date,', ',-1),' CDT',1),'MMM DD hh:mm:ss') as FormattedDate

From

Source;

Right Join

Load Person,

Resident Data Group by Person, New_Office;

DROP Field FormattedDate;

Or you can try FirstSortedValue function in straight table.

Straight table:

Dimensions:

Persons

New_Office

Expression:

FirstSortedValue(Completed_Date,-Date#(Subfield(SubField(Completed_Date,', ',-1),' CDT',1),'MMM DD hh:mm:ss'))

Try max(Timestamp(CompletedDate)) as you are having timestamp in your date field

Anil I don't see that option. However, I have been able to extract the date in a proper date format. It looks like this now : 10/19/2017.

And I tried to run the max script you mentioned above. I think it brought the maximum of all the dates in the table in this format "42971". I think its not correlating to the table "Inactive_AutoFire_Users_Report" . I need to have it correlated.

I am pasting my whole script here for you to see what I have.

SPT_AUDIT_EVENT:
LOAD ID As AuditID,
MODIFIED As AuditModified,
ACTION As AuditAction,
AuditAutoFireRequestee,
AuditAutoFireOffices,
Completed_Date,
Access_Date,
UPPER(AuditAutoFireOffices) & '.' & Upper(AuditAutoFireRequestee) As 'Audit Correlation Key',
date(date(floor(CREATED/1000/60/60/24))+date('1970-01-01')) as LCMCalendarDate,
TARGET As AuditTarget,
SOURCE As "Audit Requested By",
TextBetween(ATTRIBUTES, '<entry key="Business Case" value="', '"/>') As "Audit Business Case",
TextBetween(TextBetween(ATTRIBUTES, '<entry key="Approved by RA" value="', '"/>'), '(', ')') As "Audit Approved by RA",
TextBetween(ATTRIBUTES, '<entry key="Completed by (PCU)" value="', '"/>') As "AuditAutoFire Approved by PCU",
TextBetween(ATTRIBUTES, '<entry key="Completed by (DSA)" value="', '"/>') As "AuditAutoFire Approved by DSA",
TextBetween(ATTRIBUTES, '<entry key="Completed by (Manager)" value="', '"/>') As "AuditAutoFire Approved by Manager",
TextBetween(TextBetween(ATTRIBUTES, '<entry key="Approved by Manager" value="', '"/>'), '(', ')') As "Audit Approved by Manager"
//TextBetween(TextBetween(ATTRIBUTES, '<entry key="Requested By" value="', '"/>'), '(', ')') As "Audit Requested By"
FROM [..\..\QVD\SPT_AUDIT_EVENT.qvd] (qvd);

Right Join(SPT_AUDIT_EVENT)
Load Max(Access_Date) As Access_Date1
RESIDENT SPT_AUDIT_EVENT;

Inactive_AutoFire_Users_Report:
LOAD
Date(REPORT_DATE,'DD-MMM-YY') As [Report Date],
SIGNON_ID,
OPERATOR_INITIAL,
OPERATOR_NAME,
OFFICE_CODE,
JOB_STATION,
Date(LAST_LOGGED_IN_DATE,'DD-MMM-YY') As [Last Logged In Date],
INACTIVE_DURATION_IN_DAYS,
//date(date(floor(LAST_LOGGED_IN_DATE/1000/60/60/24))+date('1970-01-01')) as LCMCalendarDate1,
(Upper(OFFICE_CODE) & '.' & Upper(SIGNON_ID)) As 'Audit Correlation Key',
INACTIVE_DURATION_IN_MONTHS
FROM
[..\..\QVD\Inactive_AutoFireUsers.qvd](qvd);

Hopefully this is making sense. Thanks for your help.

May be this?

Right Join(SPT_AUDIT_EVENT)
Load Date(Max(Access_Date)) As Access_Date1
RESIDENT SPT_AUDIT_EVENT;

Hello Anil,

Yes you are very close.

I had to do that but do a group by a key.
