The following code is not attempting to solve your logic issue, just to show the values of the first and last created variables so you can follow along and see if your logic matches the values you attempted to use. data selectx; input varname $ countx ; datalines ; AA1 1. AA1 2.Dec 18, 2023 ... In between the first and last lines are the statements that create and manipulate the dataset. Note the data step ends with a RUN statement ...You must already have a variable named COUNT in the input dataset. So each time the SET statement runs the value from the input dataset overwrites the value from the previous observation. To get your example then COUNT is probably 1 for every observation. So that when you increment when ACTIVITY changes it goes to 2.Re: First and last day of month using Macros in proc sql. Hi, INTNX wants a SAS Date, and 201405 is not a SAS date (at least it's not the SAS date you want). You can use INPUT () to convert 201405 to a SAS date, something like: (untested) %put %sysfunc(inputn(201405,yymmn6.),mmddyy10.); %put %sysfunc(intnx (month,%sysfunc(inputn(201405,yymmn6 ...If you don't have a WHERE statement in your DATA step already, that would be the simple solution. Change this: if vistdat le &cutdate; to this: where vistdat le &cutdate; The WHERE statement subsets differently than IF. When using IF, the DATA step reads in observations then deletes some of them.

In the following code, the first INPUT statement reads and holds the record in the input buffer. The _INFILE_= option removes the angle brackets (< >) from the numeric data. The second INPUT statement parses the value in the buffer. data _null_; length city number $16. minutes charge 8; infile phonbill firstobs=2;I have the following dataset . data have; input profit; datalines; 52 34. 60. 57. 70; run; I want to write a program that will create a new dataset, only containing the difference between the first and last observation? In this case the code would show 70 (last observation) - 52 (first observation), so the output would be 18.

Page 2. Method #1 - Using PROC SORT to Remove Duplicates. The first method, and one that is popular with SAS professionals everywhere, uses PROC SORT to remove duplicates. The SORT procedure supports three options for the removal of duplicates: DUPOUT=. NODUPRECS. , and. NODUPKEYS. Specifying the DUPOUT= Option.FIRST.VARIABLE & LAST.VARIABLE PROBLEM.

Note that in some cases, I just need the unique instances of the variable (such as with On_Off) but in other cases I need every instance (such as with Group). I have been trying first./last. processing with by statements, but I can only get that to work with one variable at a time.

Other implementations of SQL added extra non-standard features to get around this and ultimately the SQL standard was expanded to at least include windowing functions that allow something like …

The SET and BY statements in a data step tell SAS to process the data by grouping observations together. Whenever we use BY statement with a SET statement, SAS automatically creates two temporary variables for each variable name that appears in the BY statement.Jun 23, 2016 · If you want to reproduce COUNT in the datastep you will have to use the double DOW.

Re: substract/divide each row from first row. No need for a multiple TABLE if you just want to assign values to multiple VARIABLES. Below I will show a way you could keep your "matrix" shape, but it looks like you should just restructure your so that instead of multiple variables you have multiple observations.The END=last option tells SAS to create a temporary numeric variable called last, which is initialized to 0 and set to 1 only when the SET statement reads the last observation in the input data set.Although we used the variable name last here, we could have used any valid SAS variable name. The variable is temporary in that it is placed in the program data vector but not written to the output ...var t_first t_last t_diff base1 value_last value_diff; run; 0 Likes Reply.

The session is created on the CAS server. You use the CAS statement to start a session and to connect to the SAS Cloud Analytic Services server. When you initially connect to SAS Cloud Analytic …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.

NOTE: Variable 'last.Address'n is uninitialized.I have previously written about using the Nodupkey Option in the example page Remove Duplicates in SAS.When we examine the PROC SORT Documentation for the Nodupkey Option, we can see that: "The Nodupkey Option checks for and eliminates observations with duplicate BY values".This means that the Sort Procedure considers only the variables in the By Statement and deletes any duplicate values.

The value of these variables is either 0 or 1. SAS sets the value of FIRST. variable to 1 when it reads the first observation in a BY group, and sets the value of LAST. variable to 1 when it reads the last observation in a BY group. These temporary variables are available for DATA step programming but are not added to the output data set.As Paige said, the best tool is data step,NOT sql. Anyway, there is some sql code could get first last.

The TRANWRD function does not remove trailing blanks in the target string and the replacement string. Comparisons. The TRANWRD function differs from the TRANSTRN function because TRANSTRN allows the replacement string to have a length of zero.Re: COUNTER, RETAIN AND FIRST.

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.). Get the real "data" and use that.Example 1: Remove Duplicates from All Columns. We can use the following code to remove rows that have duplicate values across all columns of the dataset: /*create dataset with no duplicate rows*/. proc sort data=original_data out=no_dups_data nodupkey; by _all_; run; /*view dataset with no duplicate rows*/. proc print data=no_dups_data;If the conditions that are specified in the IF clause are met, the IF-THEN statement executes a SAS statement for observations that are read from a SAS data set, for records in an external file, or for computed values. ...
