SUBSTR() function only works with the character variable. In order to extract last N digits you need to first convert numeric variable into char variable using PUT() function before passing it to substr function. Here is the classic example of how to extract last 4 digits from a numeric variable in SAS.

When reading a new row, initialize flag_final as the last value it was given. if first.id then do; If it's the first ID in the ordered block of IDs, do some functions. if flag eq 0 then flag_final = flag; else flag_final = .; end; If the variable flag is 0, then make the variable flag_final take the value of flag.3. Let's save aside the trtsdt and trtstm when we are on a first.id row. if first. id then do; trtsdt = datepart( stdtc); trtstm = timepart( stdtc); end; 4.

Please help 🙂. dataset have;The first two functions that actually remove blanks in SAS are the TRIM-function and the TRIMN-function. Both functions remove trailing blanks. However, they differ in how they deal with strings of multiple blanks. If a string consists of only blanks, the TRIM-function returns one blank, while the TRIMN-function returns zero blank characters.If you want to do so with PROC SQL, this has nothing to do with first./last. logic, which is a SAS Data Step concept. proc sql; create table want as. select * from sam. group by name. having value=min(value); quit; Result: name item value. naari battary 14. nehemiah ball 20.

You will note the word guess on the first line of the post here. You have not provided anything for me to work with. If you want a good answer provide some test data in the form of a datastep, post it in the code window (its the {I} above post area), and show what you want out.. You asked "SELECT DISTINCT() but not in SAS."- I showed how this works, I cannot guess your data or process or what ...By default, SAS will use not just one but all of the delimiters in the default list. This can become problematic in certain cases when your data contains multiple delimiters. In the SASHELP.BASEBALL dataset, the NAME variable contains a list of first, last and middle names. The structure is as follows: <last name>,<firstname><blank><middlename>.Jun 30, 2023 · because the time when all of the FIRST. flags will be true is when you start a new value of the first BY variable, in this case the ID variable. If you want to find the distinct observations then you should just test the value of the last BY variable, in this case the REASON variable. if first.reason then output; The following example computes annual payroll by department.

Then, we create a data step with two output data set. One with unique observations and one with the duplicate observations. Finally, we use the first keyword to move the first unique observation of the data set to the output data set …

Re: Fill missing values with the previous values. A more important question would be why the "data" is like that in the first place. It looks a bit like your reading in a produced report - not a recommended approach for multiple reasons (populations, calculations, assumptions etc.).

You can extract the last 2 characters of the text strings, with the following 3 steps: 1. Determine the length of the string with the LENGTH function. 2. Specify the starting position to extract the last N characters. You do so by subtracting the N-1 characters from the length of the original string. 3.Using a subsetting IF statement before testing the FIRST.ID flag could have, in theory, caused a problem as it could have removed the observation where FIRST.ID is true. But since you are removing all of the observations where ID is missing it doesn't really cause any trouble. Your data step is equivalent to these other forms: Solved: Hello ...Limiting output#.

As far as I know all the source systems will create the string with proper delimiters to identify. If not you may need to change the way your source data is sent.INTRODUCTION. The LAG function is one of the techniques for performing computations across observations. A LAGn (n=1-100) function returns the value of the nth previous execution of the function. It is easy to assume that the LAGn functions return values of the nth previous observation.

You can use the following basic syntax to calculate a cumulative sum in SAS: data new_data; set original_data; retain cum_sum; cum_sum+sales; run; . This particular syntax creates a new dataset called new_data that contains a new column called cum_sum that contains the cumulative values of the column called sales.. The following example shows how to use this syntax in practice.Comparisons. The PRXCHANGE function is similar to the CALL PRXCHANGE routine except that the function returns the value of the pattern-matching replacement as a return argument instead of as one of its parameters. The Perl regular expression (PRX) functions and CALL routines work together to manipulate strings that match patterns.This may get close to the duration depending on responses to those questions. data want ; set jobhist ; by id jobnum farm_ever ; retain start ; if first.id then start= -999; if farm_ever=1 and start=-999 then start=startyear; else if farm_ever=0 then start=-999; if last.id and start ne -999 then duration = endyear-start; run ;This example creates a SAS data set and executes the PRINT procedure with FIRSTOBS=2 and OBS=12. The result is 11 observations, that is (12 - 2) + 1 = 11.
