In this post, we will see various methods to count number of rows (records) in SAS table. Then I have couple of ways to do so. Method I : Proc SQL Count (Not Efficient) In the example below, we will use CARS dataset from SASHELP library. As you can see those are some of my output data.

You can delete one or more rows from a view's underlying table, with some restrictions. I assumed there could be an easier way besides manually checking and deleting each table.

Re: Removing records from SAS Dataset Posted 02-02-2009 (564 views) | In reply to deleted_user if your data can be put in order by the date on which you base "latest", then something like this is worth trying[pre] proc sort data= your.data out= sorted ; Using a SAS transaction dataset to delete records from SQL Server table Posted 01-05-2018 (1668 views) I have a SQL server master table, and a SAS dataset of transactions which are deletions to be applied. Although the new parameter in SAS version 9.1 exists so that duplicates can be found the macro developed above can be modified to suit different purposes, example finding records where there are three or more instances of the record in the dataset.

We live in a world of data – small data, big data, and data in every conceivable size between small and big. (with only one variable) using a data step of the form In today’s world data finds its way into our lives wherever we are. Can anyone tell me how to do that? See Updating PROC SQL and SAS/ACCESS Views in the SAS 9.2 SQL Procedure User's Guide. Then I have couple of ways to do so. If I understand correctly, you want to remove every observation from your dataset where more than one observation has the same value of your "key" variables (removing ALL duplcates).

Re: Fastest way to delete rows from a dataset by key Posted 06-17-2016 (7153 views) | In reply to EduxEdux Usually in data warehouse you don't delete any records, just mark certain records as not valid any more, perhaps using end dates. proc sql; delete from server.data where Date >= today() - 30; quit; Is the original table a SAS dataset? In macro, we generally tell SAS to go to the next iteration only when SAS dataset is non-empty. PROC DELETE delete all the data set, what i need is to delete all the data set observations not the data sets it self. I'm working in SAS with a file with roughly 80000 observations, I've decided to keep 11 variables. There are more rows like row 4 need to be deleted.). The DELETE statement deletes one or more rows in a table or in a table that underlies a PROC SQL or SAS/ACCESS view.
