creating a new column using existing column

Thu, 13 Jul 2017 17:50:14 GMT

Hello,

I am having little bit of a difficulty trying to create a new column using if statement on an existing column

i am doing

IF(NRTT_Plan='NEW,'RENEW','TRANSFER IN', 1,

IF(NRTT_Plan='NEW,'TRANSFER IN',2,

IF(NRTT_Plan='TERM',3,

IF(NRTT_Plan='TERM' AND Member_Age='0.26', 4))) as Status_Flag,

but this does not work. i tired putting them in parenthesis but only IF(NRTT_Plan='TERM',3, is loaded into table and nothing else.

What am i doing wrong here. Please help me.

Thank you,

Syed.

HI,

Can you please share some sample data.

Try this may be:

IF(Match(NRTT_Plan, 'NEW,'RENEW','TRANSFER IN'), 1,

IF(Match(NRTT_Plan, 'TERM'), 2,

IF(Match(NRTT_Plan, 'TERM') AND Member_Age='0.26', 4))) as Status_Flag,

Try

If(match(NRTT_Plan,'RENEW',1,

if(match(NRTT_Plan,'TRANSFER IN'),2,

if(match(NRTT_Plan,'TERM') AND Member_Age='0.26',4,3))) as Status_Flg

If you don't move the TERM and Member Age logic above the regular TERM logic you will never get any number 4 statuses.

Syed,

Are you trying to put these into one and only one slot 1 - 4? Because you have duplication.

In NRTT_Plan can there be only one of the values or multiple.

You could do it either of these ways, however you will get the same records meeting conditions 1 & 2

IF(NRTT_Plan='NEW' or NRTT_Plan ='RENEW' or NRTT_Plan ='TRANSFER IN', 1,

IF(NRTT_Plan='NEW' or NRTT_Plan ='TRANSFER IN',2,

IF(NRTT_Plan='TERM' AND Member_Age='0.26', 4,

IF(NRTT_Plan='TERM',3 )))) as Status_Flag

IF(Match(NRTT_Plan,'NEW,'RENEW','TRANSFER IN')>0, 1,

IF(Match(NRTT_Plan,'NEW,'TRANSFER IN')>0, 2,

IF(NRTT_Plan='TERM' AND Member_Age='0.26', 4,

IF(NRTT_Plan='TERM',3 )))) as Status_Flag

The only difference between your first condition and second seems to be that #1 has 'RENEW' in it

Without knowing your intention - it is hard to give you direction. Its possible that you want the same record to appear with a value 1 and 2. Only you know that answer.

You did need another right paren on your IF statement -- you had 4 conditions so you needed 4 right parens ')' at the end.

please post some sample values and your expected result as well.

thanks

this four flags are for

1= active

2=new

3=Termed

4= termed at the age of 26

1 which is "Active' can be New members, renewed members and Transfer in

2 which is 'New' can be members that just signed up and are new to the plan. so they can only be New or Tranfer in as renwed members are already established and cannot be considered new.

3 is termed and 4 is Termed at age 26.

so yes, #2 will be same as #1 - Renewed members

i followed the steps that Wallo Atkinson suggested but the new field is not generated in the resulting column. Will try your method and see if it works.

Thank you,

Syed.

i tried your both approaches but non were able to load filed 'New' for me.

please find the sample data in the attachment. I need four groups but no matter how i try it, the resultant column has only 3. I am not able to load field 'New' in it.

Try this? Change the path accordingly.

Table1:

LOAD Age,

[Member #],

NRTT_Plan,

Payment,

IF(NRTT_Plan='NEW' or NRTT_Plan ='TRANSFER IN',2,

IF(NRTT_Plan='NEW' or NRTT_Plan ='RENEW' or NRTT_Plan ='TRANSFER IN', 1,

IF(NRTT_Plan='TERM' AND Age='26', 4,

IF(NRTT_Plan='TERM',3 )))) as Status_Flag

FROM

[..\Desktop\RoughForum_Files\Sample_Data.xls]

(biff, embedded labels, table is Sheet1$);

That's because everything that WOULD be in Status 2 falls into status 1 first.

You have some redundancy. You can't have a record be status 1 and 2 simultaneously.

Which would take precedence active or new? Can a record be New but not Active?

Wild guess, but maybe you really want.

LOAD NRTT_Plan,

IF(NRTT_Plan='NEW' or NRTT_Plan ='TRANSFER IN',2,

IF( NRTT_Plan ='RENEW' , 1,

IF(NRTT_Plan='TERM' AND Age='26', 4,

IF(NRTT_Plan='TERM',3 )))) as Status_Flag,

[Member #],

Payment,

Age

FROM

(ooxml, embedded labels, table is Sheet1);

If using Match - that is case sensitive so your case has to match also. 'NEW' is not the same as 'New' or 'new'. If you want case insensitive then use Mixmatch. Let me check my answer now that you have posted more information.

1 which is "Active' can be New members, renewed members and Transfer in

2 which is 'New' can be members that just signed up and are new to the plan. so they can only be New or Transfer in as renewed members are already established and cannot be considered new.

Ok so you will need an additional condition for #2 which says they cannot be 'RENEW'

IF((NRTT_Plan<>'RENEW' AND (NRTT_Plan= 'NEW' or NRTT_Plan ='TRANSFER IN')),2,

Re: creating a new column using existing column

mjtaft2017 — Fri, 14 Jul 2017 17:19:07 GMT

according to your sample - a member can only have one status flag.

You have to determine which takes precedence -- do you want to assign ACTIVE or NEW for those that meet more than one

You can try my reply from above and put that before the line you currently have for the ACTIVE members. That would slot your RENEWS as #1 .... like this

IF((NRTT_Plan<>'RENEW' and (NRTT_Plan= 'NEW' or NRTT_Plan ='TRANSFER IN')),2,

IF(NRTT_Plan='NEW' or NRTT_Plan ='RENEW' or NRTT_Plan ='TRANSFER IN', 1,

I agree with your solution if a person can only have 1 plan. If a single member can have multiple plans - then I think the premise needs to be reworked. According to the sample data - it would appear a member has only 1 plan, but perhaps the sample does not tell the whole story

Re: creating a new column using existing column

Agreed.

If a person needs to be counted in more than 1 then it probably should be done in Set Analysis on the frontend.

Otherwise the Status Flag should be put in a separate table in the data model with a 1 to many join in the data model.

So each record can have more than 1 status.

Hi,

I guess your separate status_flag table is the best solution in this case.

One possible implementation could be:

table1:
LOAD AutoNumberHash128(NRTT_Plan,Age) as %StatusKey,
    NRTT_Plan,
    [Member #],
    Payment,
    Age
FROM  (biff, embedded labels, table is Sheet1$);

tabStatus:
CrossTable (temp, Status_Flag)
LOAD Distinct
    %StatusKey,
    If(NRTT_Plan='NEW' or NRTT_Plan ='TRANSFER IN',2),
    If(NRTT_Plan='NEW' or NRTT_Plan ='RENEW' or NRTT_Plan ='TRANSFER IN', 1),
    If(NRTT_Plan='TERM' AND Age='26', 4),
    If(NRTT_Plan='TERM',3 )
Resident table1;

DROP Field temp;

hope this helps

regards

Marco
