While you may have obscure problems with names like Vincent Van Gogh, your basic idea for first and last name are correct. You can check whether there are 3 names, and only assign the middle name if there is one. The DATA step syntax is easy: if countw (fullname) > 2 then second = scan (fullname, 2, ' '); The SQL syntax is harder, and just a ...

A couple of updated notes: This is better done using the nth groupby method, which is much faster >=0.13:. g.nth(0) # first g.nth(-1) # last You have to take care a little, as the default behaviour for first and last ignores NaN rows... and IIRC for DataFrame groupbys it was broken pre-0.13... there's a dropna option for nth.. You can use the strings rather than built-ins (though IIRC pandas ...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.The last column of the table tells whether the variable is available for processing in the DATA step. If you want to rename the variable, use the information in the last column. ... it is helpful to know that SAS drops, keeps, and renames variables in the following order: First, options on input data sets are evaluated left to right within SET ...would be or even what the last variable in the list would be when the code was written. In the above example for &pggrp = 016_017 the string FIRST.&&KEY&KEYCNT resolves to FIRST.OCC1. Since there are three variables in the BY statement, &KEYCNT is 3, and &KEY3 is OCC1. BUILDING FROM A SAS DATA SET Often the information needed to construct theThe Right Way to Obtain Duplicates in SAS. To obtain ALL duplicates of a data set, you can take advantage of first.variable and last.variable . Here is the code to do it with the above example data set of test; you will get both the single observations and the duplicate observations.

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.Hear from SAS execs, best-selling author Adam Grant, Hot Ones host Sean Evans, top tech journalist Kara Swisher, AI expert Cassie Kozyrkov, and the mind-blowing dance crew iLuminate!

If you would like to define different notes based on the contents in the table, then you should do this: break after pagecounter/page; %if &flag ne 1 %then. %do; compute after pagecounter;SAS places FIRST.variable and LAST.variable in the program data vector and they are therefore available for DATA step programming, but SAS does not add them to the SAS data set being created. It is in that sense that they are temporary. Because SAS does not write FIRST.variables and LAST.variables to output data sets, we have to do some ...Jul 15, 2020 · In the above example what I am lloking for is writing code to basically say: If your first observation for the customer is "C" and your last is also "C" then indicator = "PASS". but if your first observation of the flag is "C" and your last observation is "O" then your indicator = "FAIL". So the result should look like this. If you use a by statement along with a set statement in a data step then SAS creates two automatic variables, FIRST.variable and LAST.variable, where variable is the name of the by variable. FIRST.variable has a value 1 for the first observation in the by group and 0 for all other observations in the by group.

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;

So your basic problem is you are using macro logic where you should be using normal logic. %if first.&rank_column. = 1 %then %do; Will never be true, even if rank_column is empty because the string first. can never equal the string 1. But if you code it using SAS code instead of macro code.While Andreas already answered your question, I thought you might find it equally useful to know that the reason that you don't have to include Total_Amount_Last_Learning in a retain statement is because it is automatically retained because you used in the statement TOTAL_AMOUNT_LAST_EARNING + AMOUNT_LAST_EARNING ; . The variable on the left in such sum statements are automatically retained.Dr. Smith T.

Summary. In summary, the BY statement in the DATA step automatically creates two indicator variables. You can use the variables to determine the first and last record in each BY group. Typically the FIRST.variable indicator is used to initialize summary statistics and to remember the initial values of measurement.

For your first question, the issue is that you can only alter the page numbers at a procedure break.

If a string consists of only blanks, the TRIM-function returns one blank, while the TRIMN-function returns zero blank characters. kayla head kandylas vegas jail inmate information Posted 05-17-2011 07:33 PM (1296 views) This is usually how I did when I want to move a column to be the first column in the dataset: data a2; retain idx; set a1; idx = _n_; run;SAS matches the first value in the list with the first variable in the list of elements, the second value with the second variable, and so on.

Projects in your data is a possible candidate: data have;In that case, SAS would not set any flags or automatic variables other than _N_, _ERROR_, etc. However, if you WANT to use FIRST.byvar and LAST.byvar processing then you have to "turn them on" with a BY statement inside your DATA step program. So the 2 BY statements in your code are really independent of each other.
