Hi,
Is it possible to export a csv file with only the headers when there's no data to export?
For multiple purpose I automatically generate csv files that will be retrieved by other parties. They can only process the csv files when the column headers are always shown.
But now, when for some reason there's no data to export, also the column headers are left out. This causes fail overs at the receiving end.
Can someone help me?
This is the example of the way I now publish the csv file;
The order of the statements in your data step is wrong. SAS will stop when the SET statement reads past the end of the data.
The order should look like this. Then it will write the headers even if the input has 0 observations.
data _null_;
file ... ;
if _n_=1 then ... ;
set ... ;
put ... ;
run;
The %DS2CSV Macro handles this
/* With observations */
%ds2csv(data=sashelp.class, runmode=b, csvfile=YourPathHere\class.csv);
/* Without Observations */
data NoObsClass;
set sashelp.class(obs=0);
run;
%ds2csv(data=NoObsClass, runmode=b, csvfile=YourPathHere\NoObsClass.csv);
You can read about the macro in the DS2CSV Documentation
