Export .sas7bdat from SAS Studio to local machine - sas

I am using SAS Studio(completely browser based). I need to export a dataset to my local machine in the .sas7bdat file format. I think it should be something like PROC EXPORT data = sqrtReg2 outfile = "C:\Documents\SAS\Target_Wins.sas7bdat";. But that returns the error ERROR: Unable to determine datasource type. Please use the DBMS= option.. But the DBMS option only allows for CSV, tab and DLM. How do I export this data set to my local machine in the .sas7bdat file format?

With the SAS University Edition you can setup shared folders in the virtual machine where SAS runs that are mapped to actual folders on your real machine.
For example you might have mapped C:\Documents\SAS\ to /folders/myfolders. You cannot write to other locations on your real machine that are not mapped so that the virtual machine can see them. Check the documentation for exact details of getting the folders mapped.
The normal way to have SAS place a dataset then is to create a libref that points to the folder and then use a two level name when referencing the data set. You could create a libref named OUT for example:
libname out '/folders/myfolders/';
data out.target_wins;
set sqrtReg2;
run;
But you can also just refer to the file directly without first creating a libref.
data '/folders/myfolders/target_wins';
set sqrtReg2;
run;
Note that since SAS is actually running in Unix you cannot use CamelCaseFileNames for your SAS datasets. The files will always be in all lowercase letters.

None of the answers worked for me. Maybe because after April 2021, they have made changes to the platform(University). So, after a lot a time searching, I found what I needed.
You can easily export the sas dataset to csv, xslx, by just right clicking on the dataset and selecting export as csv, xlsx, etc.
For exporting to sas7bdat file, do:
Create your dataset, I am creating from csv, so create a program1(.sas) to first convert csv to sas dataset.
proc import file="/home/u123/mydata.csv"
out=work.mydata
dbms=csv
replace;
run;
This will create your sas dataset.
IMP Go to "Libraries" at the right bottom, and hit "My Libraries" -> New Library -> Name it(eg - test), give path(eg - /home/u123/sasuser.v94)
Check library creation, and HIT "Refresh Library Session" on right pane, don't refresh the page.
Now create a separate program2(.sas), to export the dataset to .sas7dbat file.
PROC COPY IN=WORK OUT=test;
SELECT mydata;
run;
quit
This will create a .sas7bdat file in your directory, with same name as your dataset.
These exact steps worked out for me.

It won't work for 2 reasons.
You can't export a SAS dataset to a SAS dataset (.sas7bdat) - Proc Export will export to excel, csv, etc but not to a .sas7bdat.
you're running SAS Studio from within a Virtual Machine that uses Linux as OS so path to create an external file is incorrect. You haven't hit this error but you will once you use the right filetype.
When you installed SAS Studio you should have created a shared folder. This folder is accessed from within SAS Studio as /folders/myfolders/filename.
So your code should looks like this:
PROC EXPORT data = sqrtReg2
outfile = "/folders/myfolders/Target_Wins.csv";
run;
From Windows the path to this shared folder will depend upon where you installed your VM.
Option 2
If what you need is the dataset then try the following code:
libname out "/folders/myfolders/";
proc copy in=work out=out;
select sqrtReg2 ;
run;
Again, table will be in your shared folder which is accesible from Windows.

I used just like option 2 in the above answer. I need to export my polygon data from SAS Studio in my virtual machine so that i can import it to my Visual Analytics. and it worked just fine.
libname out "/folders/myfolders/";
proc copy in=work out=out;
select my_map;
run;

Read a sas7bdat file in SAS Studio

I've scoured the internet but cannot seem to figure this out. My question is, if I have a sas7bdat file, how can I read a sas7bdat file in SAS studio so that I can work with it.
I've tried:
libname test 'C:\Users\name\Downloads\test.sas7bdat';
which gives me the error that library test does not exist and if I try the following, I know that I need an INPUT which I don't know of unless I can see into the file.
DATA test;
INFILE 'C:\Users\lees162\Downloads\test.sas7bdat';
RUN;
Is there something I'm missing?
Libref's that you create via the LIBNAME statement point to directories, not individual files.
libname test 'C:\Users\name\Downloads\';
INFILE is for reading raw data files. To reference an existing SAS dataset you use a SET statement (or MERGE,MODIFY,UPDATE statement).
set test.test ;
Note that you can skip defining a libref and just use the quoted physical name in the SET statement.
DATA test;
set 'C:\Users\lees162\Downloads\test.sas7bdat';
RUN;
Of course to use C:\ in the paths this is assuming that you are using SAS/Studio to point to full SAS running on your PC. If you are using SAS University Edition then it is running in a virtual machine and you will need to put the SAS dataset into a folder that is mapped to the virtual machine and then reference it in the SAS code with the name that the virtual machine uses for the directory.
So something like:
DATA test;
set '/folders/myfolders/test.sas7bdat';
RUN;
Libname is just pointing the location and once you have done that you can use that libname followed period and dataset in your set statement
libname test "C:\Users\name\Downloads";
DATA test;
set test.asl;
RUN;
One possible reason could be that you are using the SAS University edition (It doesn't support variable library address).
From one of the SAS community Q/A:
"When you are using the SAS University Edition, any libraries that you create must be assigned to a shared folder. You access your shared folder with this pathname: /folders/myfolders/. Always use '/' in the directory path, even in Windows operating environments"
After setting the directory address, proceed as instructed by Tom above in one of the answers.
Suppose you have the sas dataset at location. C:\Users\name\Downloads\test.sas7bdat
libname download 'C:\Users\name\Downloads';
proc sql;
select * from downloads.test;
run;
you can read your dataset like a table using the proc sql, in case you want to query the dataset, but if you want to modify the existing dataset then you can use the data setp as mentioned by #krian.

Data does not exist

I'm facing a very weird problem.
I've assigned a libname such as
libname TEST_LIB "/Info-One/...." /*have removed the exact location*/
/*The dataset TEST_DATA is visible in this output*/
proc datasets lib = TEST_LIB;
RUN;
/*This statement throws an error saying the file does not exist*/
DATA TEST_DATA_2;
set TEST_LIB.TEST_DATA;
RUN;
I'm running this code in SAS Enterprise guide connected to the remote server.
I'm also able to navigate to the location from File explorer and drag it into Enterprise guide and then the dataset is visible. But even if I double click on the dataset from the defined library then it says that the dataset does not exist.
I've run out of ideas now and I'm not sure how to troubleshoot this.
A couple of things that I've tried/checked
Case sensitivity is not an issue
The filename does not have spaces
I have permissions to the folder because I can work normally with another dataset that I created and placed in that folder
In fact if I copy the data to excel, upload the excel to SAS to create a SAS dataset and place it in the same location with a different name, I face the same issue!!
Would really appreciate any ideas that you guys may have, not just on why its happening, but also how to bypass it
Transferred from comments and expanded
Here are 2 possibilities:
The filename of the data set may contain uppercase. This is an unlikely but possible scenario:
On Unix systems filenames are case sensitive. A data set name in a SAS program will be mapped internally to a corresponding lowercase named data file (those sas7bdat files at the operating system level). If a copy process somehow creates a .sas7bdat data file on Unix whose name is mixed case or uppercase, the SAS session won't map to it. In such a scenario, the SAS file explorer might list a data set, but be unable to open it. However, a direct file reference to the data set might work, such as set '~/project1/datasets/MyWeirdlyCasedDataset';
There is a file permission problem with the folder mount, allowing reading of directory entries (the filenames) but not the file contents (the data sets) within. Try opening a terminal session (putty or mobaxterm) and see what the detailed directory listing is for the data folder (ls -l) You might have to also look at the access control lists (lsacl) and get network and IT admin involved.
Are you sure that is a dataset?
Put memtype=data in Proc Datasets as below
proc datasets lib = TEST_LIB memtype=data;
RUN;

What are ways to export data from tables in SAS DI?

I am very new to SAS and I have some tables in SAS DI under inventory which I need to export to text file, what are the easy to do this? Can I somehow create a program in SAS EG to display the data in there then export?
In SAS Data Integration Studio:
You can either use a File Writer or User Written Code transformations to export the table to a file. If you are using User Written Code just use a proc export Example here and DI Studio documentation here.
In SAS Enterprise Guide:
Navigate in the SAS Folder to where your table is saved and double click to open the table, then you will see in the top right the option to export/send to excel. Or you can write a proc export in a program (file-New- Program)

Converting Excel file into SAS Dataset

I'm trying to import a dataset into SAS enterprise guide, however am having trouble 'converting' my excel file into a new SAS dataset file. Any easy way to do this?
Like this:
libname LIBRARYNAME 'filesource...'
data Project2
set exdata.Project;
<math>
run;
But the file I have the data in is a Excel file... and it can't find it
You are close, if you have to ability to access local files something like this may work. You may need to play around with the sheet name. Open the library once it's assigned to see how SAS refers to the sheets.
Libname mylib XLSX 'path to XLSX file';
Data want;
Set mylib.sheet_name;
Run;
Libname mylib;
Otherwise if your using EG on a server and your excel file is local you can import using the GUI tool.
In Enterprise Guide, you can create an import step. This is preferable for EG projects that will always be in EG, as it is OS-agnostic, server-agnostic, and version-agnostic, and leaves a single step on the process flow that you can move around where you need it to be run.
Choose (File menu) -> (Import Data), and then it will guide you through importing the file. When it completes, this will leave on your process flow an Import Data step that you can link to other programs (if you're using this program repeatably).
During that wizard, you will tell it what dataset name you want it saved as, and that will then exist as a SAS dataset in your project (usually in the work library unless you specify otherwise).

SAS File <lib>.<dataset>.DATA does not exist but proc datasets shows dataset

I'm trying to move a SAS dataset over to our Linux server from a client. They created it on SAS 9.4, 64-bit on Windows 7. I'm using SAS 9.4, 64-bit on Linux.
If I do
proc datasets library=din;
run;
I get the following in my log
Libref DIN
Engine V9
Physical Name /sasUsr/DM/DATA/SAS_DATA/201510_SSI
Filename /sasUsr/DM/DATA/SAS_DATA/201510_SSI
Inode Number 46358529
Access Permission rwxrwxr-x
Owner Name cvandenb
File Size (bytes) 4096
Member File
# Name Type Size Last Modified
1 SAMPLE_FROM_SSI DATA 131072 09/14/2015 17:07:01
2 TEST DATA 131072 09/15/2015 09:35:59
15 run;
but when I do
data test;
set din.sample_from_SSI;
run;
I get
18 data test;
19 set din.sample_from_SSI;
ERROR: File DIN.SAMPLE_FROM_SSI.DATA does not exist.
20 run;
I also created a dummy dataset din.test and was able to proc print it. This seems to either be a version compatibility issue or transmission issue. I thought this would be straightforward. Any suggestions? I'm moving the file from windows to Linux with WinSCP. I'd rather not have to request a .csv and create the input statement, but will if I have to. Your help is appreciated.
Thanks,
Cory
If you are talking about an actual SAS dataset then make sure that the name of the file is in all lowercase letters and has the extension of .sas7bdat. If the source file from Windows did not have an extension of .sas7bdat then perhaps you are not dealing with a SAS dataset, but some other type of file.
In SAS code it does not matter whether you reference a dataset using upper or lower case letters. So you can reference a datasets as sample_from_SSI or Sample_From_Ssi to refer to the same file. The same is true of general filenames on a Windows machine. But on Unix system file names with different use of upper and lower case letters are distinct files. SAS requires that the filename of a SAS dataset must be in all lowercase letters.
So if you write:
libname DIN '/sasUsr/DM/DATA/SAS_DATA/201510_SSI';
proc print data=DIN.SAMPLE_FROM_SSI;
run;
Then you are looking to make a listing of the data in a file named:
/sasUsr/DM/DATA/SAS_DATA/201510_SSI/sample_from_ssi.sas7bdat
I usually get a note about CEDA in this case not missing data.
Create either a CPORT or XPORT file using the associated proc, PROC CPORT or XPORT and then move that file.
Try referring to the data with all caps as well, which I don't think should be the issue, but is possible.
I would try using PROC COPY directly on the libname, as you can select memtype=data that way without explicitly specifying the file.
If SAS still can't do that, then you might have a permissions issue or something else that is outside of the SAS realm I suspect.
Try using PROC CPORT and PROC CIMPORT.
Use the CPORT Procedure to convert the file into a transport file.
Use the CIMPORT Procedure to convert the transport file to a SAS format.
There is an example that sounds similar to what you are doing here.
According to SAS, the general procedure is:
A transport file is created at the source computer using PROC CPORT.
The transport file is transferred from the source computer to the target computer via communications software or a magnetic medium
The transport file is read at the target computer using PROC CIMPORT.
Note: Transport files that are created using PROC CPORT are not
interchangeable with transport files that are created using the XPORT
engine.
If that doesn't work, or it is taking a very long time to figure out, it would be faster to ask them for a CSV and import it directly using PROC IMPORT. It should read in quite easily, especially if it comes from PROC EXPORT.
