Corrected version. Data out; set in; by social_security_number year; if first.year then output; run; Explanation. You can have numerous by variables, and for each one first and last automatic variables are generated. In this case first.social_security_number would return only one record per social_security_number.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. 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 ...One reason not to place names in a single field, typical reporting on names often is done on alphabetical by last name then first name. Second names with embedded spaces get hard to distinguish which is first or last programmatically when needed. If you separate them at entry then there is never a question.

Sad to read this. Luckily, this forum is full of nice people who spend a lot of their free time helping other members with their SAS (and statistics) questions. It's a great place for learning SAS (which is actually a never-ending task) because you can see how problems of all levels are tackled by experts with various backgrounds.You can use the LAG function in SAS to retrieve lagged values of some variable.. This function uses the following basic syntax: lag1_value = lag (value); By default, lag finds the previous value of some variable. However, you can use lag2, lag3, lagn, etc. to calculate the 2-lagged, 3-lagged, n-lagged, etc. values of some variable.. The following examples show how to use the lag function in ...Re: Finding first (or last) record using SQL. You could use the SQL to do ORDER BY before using the data step for First or Last processing. Solved: I typically use first. and last. in data step to select the first (or last) recordd within an ID. It is straightorward in SAS data step but.

Example 13.13. The following program tells SAS to process the sales data set by Store and Dept, so we can get a behind-the-scenes look at how we can find the first and last observations of two subgroups: LIBNAME stat481 'C:\yourdrivename\Stat481WC\01sasdata\sasndata'; PROC SORT data = stat481.sales out = srtdsales; by Store Dept;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.

SAS' Charu Shankar shares her PROC SQL expertise by showing you how to master the WHERE clause using real winter weather data.

2. To have SAS create FIRST. and LAST. automatic variables you need to use a BY statement. If you want the new variable to be coded 1/0 then no need for the IF statement, just assign the automatic variable to a new permanent variable. To make one variable that is 1 for the first and the last then just use an OR. set have; by logflag ; timeflag ...

2. first observation after 12.30pm each day. 3. first observation after 4pm each day. My dataset has 8000 obs spanning 65 days (all days are week days, no obs on weekends), and so I wish for this new data set to have only 3 obs each day, i.e the dataset would have 65*3=195 observations. if say, there was no more records after 4pm, then yes that ...CATT(item1, item2 <, item3, item4, …, item n>). CATS(item1, item2 <, item3, item4, …, item n>). The items 1 to n are the strings you want to concatenate. The CATX function has an extra, obligatory argument, namely a separator argument. With this argument, you can separate the input items in the output string.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 ... The next statement tells SAS when to reset the count and to what value to reset the counter. SAS has two built-in keywords that are useful in situations like these: first. and last. (pronounced "first-dot" and "last-dot"). Note that the period is part of the keyword. The variable listed after the first. keyword is temporary variables: FIRST.Age and LAST.Age. SAS reads ahead by one observation as it passes through the data and sets the automatic variable values to 1 when the first or last values in a group are processed and 0 otherwise. The FIRST.variable and LAST.variable values indicate whether an observation is: • the first in a BY group

Hey Tapas, I just wanted to share a simplest method to remove the last char of any string, this is amazing and working perfectly for me. data test; input ur_string$; ur_string =scan ( ur_string ,-1); cards; ABC+. aaaaa+.You can use the following methods to quickly concatenate strings in SAS. Method 1: Concatenate Strings with Space in Between. Method 2: Concatenate Strings with No Space in Between. Method 3: Concatenate Strings with Custom Delimiter. The following examples show how to use each method with the following dataset in SAS: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.You can use the scan() function in SAS to quickly split a string based on a particular delimiter. The following example shows how to use this function in practice. Example: Split Strings by Delimiter in SAS. Suppose we have the following dataset in SAS:Re: first and last observations using proc sql. Since SQL is a column based language, doing calculations according to row numbers is not SQL's cup of tea. Maybe you can do some complicated query using the unsupported monotonic function. But, this is so much easier done with data step.

Re: If first. then group by; how to restart count. You have to include the variables in the BY statement if you want SAS to set values for FIRST. and LAST. variables for them. You have to tell SAS not to reset the new variable COUNT to missing when it starts the next iteration.

The data will need to have columns that support a definitive within group ordering that can be utilized for MAX selection and then applied as join criteria. Projects in your data is a possible candidate: data have;data want; set have; by id; where var1 >= 0.5; if first.id; run; The interaction of the BY and WHERE statements is important. WHERE sets up first.id and last.id based on only the observations that pass the WHERE filter.@AJ_Brien:. You're talking about numeric and character variables. However, in your sample output ACC, TIME, and MONEY are all left-justified. Whatever SAS interface you're using to view the data shown here, it's a sure sign that these variables are stored as the character type.I generally use retain with by-group processing and either first or last dot variables to manipulate my data like so: data ByGroup1; set DS1; by ID1 ID2; retain Count; if first.ID1 then Count = 0; Count + 1; run; But, I was reading a post of SAS.com where an invidual used the following method (without a retain statement).

In a WHERE expression, you cannot use automatic variables created by the DATA step (for example, FIRST. variable, LAST. variable, _N_, or variables created in assignment statements). As in other SAS expressions, the names of numeric variables can stand alone. SAS treats numeric values of 0 or missing as false; other values as true.then First.date refers to the first player's record within the date. Also your Days calculation is probably incorrect as you are getting some days, the first days value for each team (except the first team) reflects the days between the last game of the previous team and the first of the current team. days=game_date-lag(game_date);How to achieve "Last. or First." using proc sql.
