It is a very strange request, but okay

Table:
LOAD POLICY_NO, 
     OLD_POLICY_NUMBER,   
     POLICY_EFFECTIVE_DATE, 
     POLICY_EXPIRY_DATE ,
     Policy_Effective_Year,
     UW_YEAR,
     Month_Difference
FROM temp_table.qvd (qvd);

FinalTable:
NoConcatenate
LOAD *
Resident Table
Order By ...;

DROP Table Table;

Right Join (FinalTable)
LOAD POLICY_NO,
     Min(POLICY_EFFECTIVE_DATE) as POLICY_EFFECTIVE_DATE
Resident FinalTable
Group By POLICY_NO;

I have left three dots for your Order by field... I don't know what order you want, so feel free to replace ... with the fields you wish to order by 🙂

TEMP:
 LOAD 
     POLICY_NO, 
     OLD_POLICY_NUMBER,   
     POLICY_EFFECTIVE_DATE, 
     POLICY_EXPIRY_DATE ,
     Policy_Effective_Year,
     UW_YEAR,
     Month_Difference,
   Date(POLICY_EFFECTIVE_DATE) as POLICY_EFFECTIVE_DATE
FROM
temp_table.qvd 
(qvd)  ;

NOCONCATENATE
TABLE:
 LOAD 
     POLICY_NO, 
     OLD_POLICY_NUMBER,   
     POLICY_EFFECTIVE_DATE, 
     POLICY_EXPIRY_DATE ,
     Policy_Effective_Year,
     UW_YEAR,
     Month_Difference,
   MIN(Date(POLICY_EFFECTIVE_DATE)) AS Min_Date
RESIDENT TEMP
GROUP BY
     POLICY_NO, 
     OLD_POLICY_NUMBER,   
     POLICY_EFFECTIVE_DATE, 
     POLICY_EXPIRY_DATE ,
     Policy_Effective_Year,

add

"drop table TEMP;"

after the script to remove synthetic table.

i want first order by then group by

Arthur_Fong · ‎2019-10-11

Is there any difference with your expected result if you do groupby first then order?

capriconuser · ‎2019-10-11

this is what i get..

Child Policy Min_Date
CAR/113480 28-10-2013
CAR/113480 09-10-2017
CAR/113480 01-01-2018
CAR/113480 01-04-2018
CAR/113480 20-05-2018

and this is i want

Child Policy Min_Date
CAR/113480 28-10-2013

i want only minimum date against policy and OLD_POLICY_NUMBER

Hi,

probably you are using group by with POLICY_EFFECTIVE_DATE.

Use group by only with Policy nr for example, than join this new table to the other

capriconuser · ‎2019-10-11

when i comment POLICY_EFFECTIVE_DATE from group by then i receive an error .. invalid expression

Because you have to comment the field in the load too

order and group by to get min date against policy no

group by

order by
