This is the sample data and I need to filter data based on acct_name field with first_name, middle_name and last_name fields. You could use other fields as well. But, what I need to see is the record where acct_name is totally different from any first_name, middle_name and last_name. The output should look like :Inkatha had been boycotting the process and challenging the ANC in violent street protests. The peaceful election brought enormous relief to the country and the …1. 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.proc print data=DIM; run; 1. Select First N Rows With OBS= Option. You can select the first N rows using the data step with OBS= option. This option tells SAS when to stop processing observations. In a way it helps to exclude rows and only keeps the first N-rows which you want.

I would like to replace first letter of the observatio...

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 ...A SAS operator is a symbol that represents a comparison, arithmetic calculation, or logical operation; a SAS function; or grouping parentheses. SAS uses two major types of operators: prefix operators. infix operators. A prefix operator is an operator that is applied to the variable, constant, function, or parenthetic expression that immediately follows it.

While using the below code , does SAS consider the one record per ID as the first record or the last record??? i am assuming that SAS would not consider it as the first or the last but would satisfy for first and last condition. To my surprise , using the below code single record per ID are being outptted which have time_elapse > 0 ...Initial missing values and First/Last (Jesse Coull's approach) instructs SAS to create all N records for each account, which then are filled with the existing data or remain blank This approach has additional advantages if one of the variables in the dataset is a time variableYou would do well to teach yourself. Besides reading the documentation, try running a test program. Here is an example: data mystestdata; set fromthissorted; by memberID; first = first.memberID; last = last.memberID; Run; proc print; var memberID first last; run; 1 Like.

Though LAST is available for all the last observations, the second and third last observations are not easy. data temp2; set temp; by i t; if last.i; run;

How it works. FIRST.variable = 1 when an observation is the first observation in each group values of variable ID. FIRST.variable = 0 when an observation is not the first observation in each group values of variable ID. LAST.variable = 1 when an observation is the last observation in each group values of variable ID.

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.While using the below code , does SAS consider the one record per ID as the first record or the last record??? i am assuming that SAS would not consider it as the first or the last but would satisfy for first and last condition.

It is an extensive list, but some examples are 15009, 15208, 191451652, 193760024.

The sample code on the Full Code tab takes a SAS date variable and finds the first business day of that month. It uses the INTNX function to advance to the first day of the month. Then it uses the WEEKDAY function to determine the day of the week. If the first day is a Saturday or Sunday, then it advances the FIRST variable by 2 or 1, respectively.SAS has the FIRST. and LAST. automatic variables, which identify the first and last record amongst a group with the same value with a particular variable; so in the following …Re: Reshaping data from long to wide. The transpose procedures or a data step will work fine but in Proc transpose will have to do it multiple times and join the results. See the second example in the first and second links below that illustrate how to do it either via proc transpose or a data step.Then your next two lines replace you WORK.P2_DATA dataset.

Solved: Hello, I'm a 2 month old SAS user and just started practicing COUNTER, RETAIN, FIRST. ,Last. and DO/END.variable = 1 indicates an observation is the last observation in a BY group; Although FIRST.variable and LAST.variable temporary variables are not automatically written to a SAS data set, once identified they can be used for special processing, reporting purposes, the creation of new variables, modification of existing variables, the structural ...

As was shown, MONOTONIC () is unreliable when used in conjunction with a HAVING clause. By splitting the SQL into two steps, it works, but just look at this: data Test; do I=1 to 1e7; output; output; end; run; data Test_first; set Test; by I; if first.I; run; proc sql; create table Test_monotonic as.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;

Method II. Another method to select the first N rows from a dataset is using the OBS= -option. With this option, you can specify the last row that SAS processes from the input dataset. So, in the example below, SAS processes all the observations from the work.my_ds dataset until the fifth. data work.first_5_obs_sas;Here's an example of how that would work. Some efficiency tricks: Use format dtdate9 on your datetime variable to summarize data by date. Use Range for the date variable to obtain the max time - min time. Datetime is stored as seconds, so convert to a number by dividing by 60 for minutes and another 60 for hours.Posted 01-31-2012 05:45 PM (814 views) | In reply to littlestone. The problem is the VAR_1 is different on every observation. So within the set of constant values for ID and VAR_1 every value of VAR_2 is unique. data want ; set test; by id var_2 notsorted; var_3 = last.var_2; run; 3 Likes.These keywords identify the first and last record in the grouping variable indicated after the BY statement. When an employee ID is unique, the first and last record will be the same row. Thus our code outputs employee ID's where the first and last records are not the same, to a dataset called "dupes", and all the other unique records are ...Inkatha had been boycotting the process and challenging the ANC in violent street protests. The peaceful election brought enormous relief to the country and the …The TRANWRD function replaces all occurrences of a given substring within a character string. 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.

You can use the FIND function in SAS to find the position of the first occurrence of some substring within a string.. Here are the two most common ways to use this function: Method 1: Find Position of First Occurrence of String. data new_data; set original_data; first_occurrence = find (variable_name, "string "); run; . Method 2: Find Position of First Occurrence of String (Ignoring Case)

Third, I think you are confusing the levels of BY variable where first. and last. operate. First. will tag any observation that is first within it's value of the specified BY-group. Since you have unique (my guess, I don't see the actual source data) values of baseline_doc/date, every row will tagged.
