SAS Certification Sampledata (Invalid Data)

PS1214 — Tue, 14 May 2019 13:30:25 GMT

Hello,

I have an invalid data problem when I am trying to generate sample datasets from this link as I go through the advanced prep guide book.

https://support.sas.com/content/dam/SAS/support/en/books/data/sampledata.txt

For example sasuser.budget2 dataset generates invalid data because the column numbers in the datalines don't match the input mapping. It looks like it has a mixed combination of tab and space delimiters. I could manually just fix the datalines by rewriting the datalines or remove the blanks, but that shouldn't be the case, and I might have done something wrong. I can't figure it out with my limited knowledge.

I have also attached a log that shows my problem.

I am using SAS Studio UNIVERSITY EDITION 2.8 9.4 M6.

Thank you for your time.

I am not sure if the tabs are there on purpose as some sort of test of your skills?

I quick and easy way to convert the tabs to spaces is to use the EXPANDTABS options on INFILE statement.

943   data _null_;
944     if eof then put n=;
945     infile 'c:\downloads\sampledata.txt' end=eof;
946     input;
947     if index(_infile_,'09'x) then n+1;
948   run;

NOTE: The infile 'c:\downloads\sampledata.txt' is:
      Filename=c:\downloads\sampledata.txt,
      RECFM=V,LRECL=32767,File Size (bytes)=427585,
      Last Modified=14May2019:09:53:31,
      Create Time=14May2019:09:53:29

n=109
NOTE: 9784 records were read from the infile 'c:\downloads\sampledata.txt'.
      The minimum record length was 0.
      The maximum record length was 132.
NOTE: DATA statement used (Total process time):
      real time           0.01 seconds
      cpu time            0.01 seconds


949   data _null_;
950     if eof then put n=;
951     infile 'c:\downloads\sampledata.txt' expandtabs end=eof;
952     input;
953     if index(_infile_,'09'x) then n+1;
954   run;

NOTE: The infile 'c:\downloads\sampledata.txt' is:
      Filename=c:\downloads\sampledata.txt,
      RECFM=V,LRECL=32767,File Size (bytes)=427585,
      Last Modified=14May2019:09:53:31,
      Create Time=14May2019:09:53:29

n=0
NOTE: 9784 records were read from the infile 'c:\downloads\sampledata.txt'.
      The minimum record length was 0.
      The maximum record length was 132.
NOTE: DATA statement used (Total process time):
      real time           0.00 seconds
      cpu time            0.00 seconds

So you could use that to fix the file.

data _null_;
  infile 'c:\downloads\sampledata.txt' expandtabs ;
  file 'c:\downloads\sampledata_notabs.txt';
  input;
  put _infile_;
run;

@PS1214, You can replace the Sasuser.budget code in your sample data with the following code. Sometimes, because of Enterprise Guide and SAS Studio this sampledata program may cause extra spaces or errors. We are working on coming out with a sample data program that is a lot cleaner so no matter what version of SAS you are using it should run your sample data with no issue.

data SASUSER.BUDGET2;
  infile datalines dsd truncover;
  input Manager:$8. Job_Type:32. WageCat:$2. WageRate:32. Yearly_Salary:32. Payroll:32.;

Thank you, that seemed to fix the log errors for invalid data, but some datasets still have incorrect/missing data.

For example:

data budget2;
        input Manager $1-7 Job_Type 9-11 WageCat $13-14 WageRate 16-21 Yearly_Salary 24-31 Payroll 33-43;

I guess there isn't a fix all line of code, and I would just have to live with it.

Also according to what @sabisw pointed out the inherent flaw of the sampledata when used in SAS Studio.

Re: SAS Certification Sampledata (Invalid Data)

PS1214 — Tue, 14 May 2019 14:39:01 GMT

Thank you.

Would I have to just manually rewrite the code for each affected dataset then?

Re: SAS Certification Sampledata (Invalid Data)

sabisw — Tue, 14 May 2019 14:40:31 GMT

@PS1214 , you shouldn't have to. It depends on what is causing the issue. If you use my code you shouldn't have any missing data set for Sasuser.Budget2

Re: SAS Certification Sampledata (Invalid Data)

PS1214 — Tue, 14 May 2019 14:47:13 GMT

There are a bunch of datasets with the same issue.

I am not sure how to figure out what causes the problem either.

I simply just copied the contents of the link and followed the instructions to generate the data.

Re: SAS Certification Sampledata (Invalid Data)

sabisw — Tue, 14 May 2019 14:51:52 GMT

@PS1214, looking at the log you provided these are the other ones:

Sasuser.visit
Sasuser.demog
Sasuser.y02jan
Sasuser.review2010

Can you verify these are the ones?

Sorry for the late response.

I did another quick look through and it looks like it is just those four.

Did not realize I was worried about just needing to fix four.

Thank you very much.

@PS1214 No worries. Glad I could help!

I will add these to the this edition's errata.
