How to print the first 10 rows with columns label in SAS - sas

PROC PRINT DATA = pg1.eu_occ obs=10 label;
RUN;
I tried print first 10 observations with their label, but it doesn't work at all. Any idea how to solve this problem?enter image description here
Thanks.

obs= is a data set option, and thus must be specified in parenthesis after the data set name. A name=value coded into a Proc statement is known as a procedure option.
Your code should be
proc print data=pg1.eu_occ(obs=10) label;
run;

This range is repeated or overlapped

Now the question I have is I have a bigger problem as I am getting "this range is repeated or overlapped"... To be specific my values of label are repeating I mean my format has repeated values like a=aa b=aa c=as kind of. How do I resolve this error. When I use the hlo=M as muntilqbel option it gives double the data...
I am mapping like below.
Santhan=Santhan
Chintu=Santhan
Please suggest a solution.
To convert data to a FORMAT use the CNTLIN= option on PROC FORMAT. But first make sure the data describes a valid format. So read the data from the file.
data myfmt ;
infile 'myfile.txt' dsd truncover ;
length fmtname $32 start $100 value $200 ;
fmtname = '$MYFMT';
input start value ;
run;
Make sure to set the lengths of START and VALUE to be long enough for any actual values your source file might have.
Then make sure it is sorted and you do not have duplicate codes (START values).
proc sort data=myfmt out=myfmt_clean nodupkey ;
by start;
run;
The SAS log will show if any observations were deleted because of duplicate START values.
If you do have duplicate values then examine the dataset or original text file to understand why and determine how you want to handle the duplicates. The PROC SORT step above will keep just one of the duplicates. You might just has exact duplicates, in which case keeping only one is fine. Or you might want to collapse the duplicate observations into a single observation and concatenate the multiple decodes into one long decode.
If you want you can add a record that will add the functionality of the OTHER keyword of the VALUE statement in PROC FORMAT. You can use that to set a default value, like 'Value not found', to decode any value you might encounter that was not in your original source file.
data myfmt_final;
set myfmt_clean end=eof;
output;
if eof then do;
start = ' ';
label = 'Value not found';
hlo = 'O' ;
output;
end;
run;
Then use PROC FORMAT to make the format from the cleaned up data file.
proc format cntlin = myfmt_final;
run;
To convert a FORMAT to a dataset use the CNTLOUT= option on PROC FORMAT.
For example if you had created this format previously.
proc format ;
value $myfmt 'ABC'='ABC' 'BCD'='BCD' 'BCD1'='BCD' 'BCD2'='BCD' ;
run;
then you can use another PROC FORMAT step to make a dataset. Use the SELECT statement if you format catalog has more than one format defined and you just want one (or some) of them.
proc format cntlout=myfmt ;
select $myfmt ;
run;
Then you can use that dataset to easily make a text file. For example a comma delimited file.
data _null_;
set myfmt ;
file 'myfmt.txt' dsd ;
put start label;
run;
The result would be a text file that looks like this:
ABC,ABC
BCD,BCD
BCD1,BCD
BCD2,BCD
You get this error because you have the same code that maps to two different categories. I'm going to guess you likely did not import your data correctly from your text file and ended up getting some values truncated but without the full process it's an educated guess.
This will work fine:
proc format;
value $ test
'a'='aa' 'b'='aa' 'c'='as'
;
run;
This version will not work, because a is mapped to two different values, so SAS will not know which one to use.
proc format;
value $ badtest
'a'='aa'
'a' = 'ba'
'b' = 'aa'
'c' = 'as';
run;
This generates the error regarding overlaps in your data.
The way to fix this is to find the duplicates and determine which code they should actually map to. PROC SORT can be used to get your duplicate records.

proc report print null dataset

I have a null dataset such as
data a;
if 0;
run;
Now I wish to use proc report to print this dataset. Of course, there will be nothing in the report, but I want one sentence in the report said "It is a null dataset". Any ideas?
Thanks.
You can test to see if there are any observations in the dataset first. If there are observations, then use the dataset, otherwise use a dummy dataset that looks like this and print it:
data use_this_if_no_obs;
msg = 'It is a null dataset';
run;
There are plenty of ways to test datasets to see if they contain any observations or not. My personal favorite is the %nobs macro found here: https://stackoverflow.com/a/5665758/214994 (other than my answer, there are several alternate approaches to pick from, or do a google search).
Using this %nobs macro we can then determine the dataset to use in a single line of code:
%let ds = %sysfunc(ifc(%nobs(iDs=sashelp.class) eq 0, use_this_if_no_obs, sashelp.class));
proc print data=&ds;
run;
Here's some code showing the alternate outcome:
data for_testing_only;
if 0;
run;
%let ds = %sysfunc(ifc(%nobs(iDs=for_testing_only) eq 0, use_this_if_no_obs, sashelp.class));
proc print data=&ds;
run;
I've used proc print to simplify the example, but you can adapt it to use proc report as necessary.
For the no data report you don't need to know how many observations are in the data just that there are none. This example shows how I would approach the problem.
Create example data with zero obs.
data class;
stop;
set sashelp.class;
run;
Check for no obs and add one obs with missing on all vars. Note that no observation are every read from class in this step.
data class;
if eof then output;
stop;
modify class end=eof;
run;
make the report
proc report data=class missing;
column _all_;
define _all_ / display;
define name / order;
compute before name;
retain_name=name;
endcomp;
compute after;
if not missing(retain_name) then l=0;
else l=40;
msg = 'No data for this report';
line msg $varying. l;
endcomp;
run;

Insert text into all cells of first column in a sas dataset

I've output 'Moments' from Proc Univariate to datasets. Many.
Example: Moments_001.sas7bdat through to Moments_237.sas7bdat
For the first column of each dataset (new added first column, and probably new dataset, as opposed to the original) I would like to have a particular text in every cell going down to bottom row.
The exact text would be the name of the respective dataset file: say, "Moments_001".
I do not have to 'grab' the filename, per se, if that's not possible. As I know what the names are already, I can put that text into the procedure. However, grabbing the filenames, if possible, would be easier from my standpoint.
I'd greatly appreciate any help anyone could provide to accomplish this.
Thanks,

Are you looking for the INDSNAME option of the SET statement? You need to define two variables because the one generated by the option is automatically dropped.
data want;
length moment dsn $41 ;
set Moments_001 - Moments_237 indsname=dsn ;
moment=dsn;
run;
I think something along these lines should be what you're after. Assuming you have a list of moments, you can loop through it and add a new variable as the first column of each dataset.
%let list_of_moments = moments_001 moments_002 ... moments_237;
%macro your_macro;
%do i = 1 %to %sysfunc(countw(&list_of_moments.));
%let this_moment = %scan(&list_of_moments., &i.);
data &this_moment._v2;
retain new_variable;
set &this_moment.;
new_variable = "&this_moment.";
run;
%end;
%mend your_macro;
%your_macro;
The brute force entering of text into column 1 looks like this:
data moments_001;
length text $ 16;
set moments_001;
text="Moments_001";
run;
You could also write a macro that would loop through all 237 data sets and insert the text.
UNTESTED CODE
%macro do_all;
%do i=1 %to 237;
%let num = %sysfunc(putn(&i,z3.));
data moments_#
length text & 16;
set moments_#
text="Moments_&num";
run;
%end;
%mend
%do_all
It seems to me (not knowing your problem) that if you use PROC UNIVARIATE with the BY option, then you wouldn't need 237 different data sets, all of your output would be in one data set and the BY variable would also be in the data set. Does that solve your problem?

SAS Drop Condition Output - Not enough variables observed in Output

I am learning drop_conditions in SAS. I am requesting a sample on three variables, however only two observations are retrieved. Please advise! Thank you!
data temp;
set mydata.ames_housing_data;
format drop condition $30.;
if (LotArea in (7000:9000)) then drop_condition = '01: Between 7000-9000 sqft';
else if (LotShape EQ 'IR3') then drop_condition = '02: Irregular Shape of Property';
else if (condition1 in 'Artery' OR 'Feedr') then drop_condition = '03: Proximity to arterial/feeder ST';
run;
proc freq data=temp;
tables drop_condition;
title 'Sample Waterfall';
run; quit;
Your conditions/comparisons aren't specified correctly, I think you're looking for the IN operator to do multiple comparisons in a single line. I'm surprised there aren't errors in your log.
Rather than the following:
if (LotArea = 7000:9000)
Try:
if (lotArea in (7000:9000))
and
if (condition1 EQ 'Atrery' OR 'Feedr')
should be
if (condition1 in ('Atrery', 'Feedr'))
EDIT:
You also need to specify a length for the drop_condition variable, instead of a format to ensure the variable is long enough to hold the text specified. It's also useful to verify your answer afterwards with a proc freq against the specified conditions, for example:
proc freq data=temp;
where drop_condition=:'01';
tables drop_condition*lot_area;
run;

sas create a variable that is equal to obs column

I have a file with 10 obs. and different parameters. I need to add to my data a new variable of 'ID' for each observation- i.e a column of numbers 1-10.
How can I add a variable that is simply equal to the obs column?
I thought about doing it with a loop, define an empty vat, run over the var and each time add '1' to previous observation, however, it seems kind of complicated. Is there a better way to do it?
You can use the Data Step automatic variable _n_. This is the iteration count of the Data Step loop.
Data want;
set have;
ID = _n_;
run;
If you opt for a Proc SQL solution, there are two ways:
1. Undocumented:
proc sql;
create table want as
select monotonic() as row, *
from sashelp.class
;
quit;
Documented:
ods listing close;
ods output sql_results=want;
proc sql number;
select * from sashelp.class;
quit;
ods listing;
#DomPazz answer would definitely work! Just in case you would like return the number of observations according to attributes, Try this:
proc sort data= dataset out= sort_data;
by * your attribute(s) *;
data sort_data;
set sort_data;
by * your attribute(s) that is listed in above proc sort statement *;
if first.attribute then i=1; <=== first by group observation, number =1
i + 1; <==== sum statement (retaining)
if last.attribute and .... then ....; <=== whatever you want to do . Not necessary
run;
first / Last is very helpful in doing row operation.
