You can use the PROC COPY statement in SAS to copy a dataset from one library to another.
This statement uses the following basic syntax:
proc copy in=folder1 out=folder2 memtype=data; select my_data; run;
Here is what each statement does:
- IN: The library where the dataset currently exists
- OUT: The library to copy the dataset to
- MEMTYPE: Specifies that only dataset should be copied
- SELECT: The name of the dataset to copy
The following step-by-step example shows how to use PROC COPY in practice to copy a dataset from one library to another.
Step 1: Create the Dataset
First, let’s create the following dataset called my_data that contains information about various basketball players:
/*create dataset*/ data my_data; input team $ points assists; datalines; Mavs 14 9 Spurs 23 10 Rockets 38 6 Suns 19 4 Kings 30 4 Blazers 19 6 Lakers 22 14 Heat 19 5 Magic 14 8 Nets 27 8 ; run; /*view dataset*/ proc print data=my_data;
Step 2: Save the Dataset in One Library
Next, we’ll use the LIBNAME statement to specify the library where our dataset should be saved:
/*define library where dataset should be saved*/ libname folder1 '/home/u13181/folder1/'; /*save dataset to library called folder1*/ data folder1.my_data; set my_data; run;
If I navigate to my folders and files, I can see that my_data has indeed been saved in folder1:
Step 3: Use PROC COPY to Copy the Dataset to Another Library
Next, I can use the PROC COPY statement to copy this dataset from folder1 to folder2:
/*define library where dataset should be copied to*/ libname folder2 '/home/u13181/folder2/'; /*copy my_data to library called folder2*/ proc copy in=folder1 out=folder2 memtype=data; select my_data; run;
If I navigate to my folders and files once again, I can see that my_data has indeed been copied to folder2:
Note: When using PROC COPY, the dataset you are copying will still remain in the original library that it came from.
