Sas split data file

The first few rows of output should look like this:. You should see that the column containing the cases for State appears completely empty, indicating that all the cases in this dataset have missing observations for State. Search this Guide Search.

Subsetting vs. Splitting When preparing data for analysis, you may need to "filter out" cases rows from your dataset, or you may need to divide a dataset into separate pieces. In this tutorial, we use the following terms to refer to these two tasks: A subset is selection of cases taken from a dataset that match certain criteria.

Subsetting Datasets by Conditions Subsets can be created using either inclusion or exclusion criteria. Example - Delete cases with a specific value Let's create a subset of the sample data that doesn't contain any freshmen students.

Subsetting Datasets by Rows It's also possible to subset your data based on row position. Splitting a Dataset Sometimes you may want to split a dataset into two or more datasets based on the value s of a variable s. Example - Splitting into multiple datasets using more than one IF statement The general code above only shows the case where a dataset is partitioned into two datasets, but it's possible to partition a dataset into as many pieces as you wish.

Example - Splitting into two datasets using IF and ELSE statements Now let's try to partition the dataset so that all freshmen are in one dataset, and all other cases are put in a second dataset. The first few rows of output should look like this: You should see that the column containing the cases for State appears completely empty, indicating that all the cases in this dataset have missing observations for State.

Joe Joe I have a date column in my data, but I am having a bit of trouble tweaking your code to achieve my desired result.

Any help would be appreciated! The code is a bit klunkier, but here's something that works. I'm don't understand the question -- or what you mean by "fun" function? Do mean macro functions? Certainly there are other ways -- some in the comments and you can find more by asking at our SAS Support Communities. Hanika, a little more complex. Chris, this is amazing and thank you! Do you have code that will export the resulting datasets to excel?

Thanks Again! Thanks for the response! I am splitting my datasets into several workbooks each with about 5 tabs. I have tried to adjust the export code in a similar manner, but each export overwrites the previous export. Hope I am making sense. I can't figure out why the sheets are overwriting. Also, on another note Thank you again!! The 'kad' Keeps just the Alpha and Decimal characters in the name, removing special characters that can't be in a SAS file name.

CARS; quit ;. Chris Amendola on January 27, am. Hey Chris, Think it's a great technique you have shared, and I don't think it's as "pointless" as you seem to suggest.

Thanks for sharing this improvement! Bowie on May 15, am. Hi John, Any idea if my output are all empty? Chris Hemedinger on May 15, am. Nikolay on February 4, am. Hello, Chris. Chris Hemedinger on February 4, am. Nikolay, Thank you for the comment. Megha on June 27, am. Does it really work Reply. Chris Hemedinger on June 27, am. It really does! Actually my end of file is not always 50, records. It can vary time to time. My real need is, I have a huge file about 30 million records that I want to break into pieces probably in 10 pieces.

I do not want to hard code record numbers as this number might increase from 30 millioin to 32 milion in very near future and so on. I would probably like to SAS automatically calculate its break points and break the file into 10 peices. I was trying to do something as simple as this, but this is not what i exactly want. Thank you. Exactly what I'm looking for.
