@brief Create a Web Ready Stored Process
|
|
@details This macro creates a Type 2 Stored Process with the mm_webout macro
|
|
included as pre-code.
|
|
Usage:
|
|
|
|
%* compile macros ;
|
|
filename mc url "https://raw.githubusercontent.com/sasjs/core/main/all.sas";
|
|
%inc mc;
|
|
|
|
%* parmcards lets us write to a text file from open code ;
|
|
filename ft15f001 temp;
|
|
parmcards4;
|
|
%webout(FETCH)
|
|
%* do some sas, any inputs are now already WORK tables;
|
|
data example1 example2;
|
|
set sashelp.class;
|
|
run;
|
|
%* send data back;
|
|
%webout(OPEN)
|
|
%webout(ARR,example1) * Array format, fast, suitable for large tables ;
|
|
%webout(OBJ,example2) * Object format, easier to work with ;
|
|
%webout(CLOSE)
|
|
;;;;
|
|
%mm_createwebservice(path=/Public/app/common,name=appInit,code=ft15f001)
|
|
|
|
For more examples of using these web services with the SASjs Adapter, see:
|
|
https://github.com/sasjs/adapter#readme
|
|
|
|
@param path= The full path (in SAS Metadata) where the service will be created
|
|
@param name= Stored Process name. Avoid spaces - testing has shown that
|
|
the check to avoid creating multiple STPs in the same folder with the same
|
|
name does not work when the name contains spaces.
|
|
@param desc= The description of the service (optional)
|
|
@param precode= Space separated list of filerefs, pointing to the code that
|
|
needs to be attached to the beginning of the service (optional)
|
|
@param code= (ft15f001) Space seperated fileref(s) of the actual code to be
|
|
added
|
|
@param server= (SASApp) The server which will run the STP. Server name or uri
|
|
is fine.
|
|
@param mDebug= (0) set to 1 to show debug messages in the log
|
|
@param replace= (YES) select NO to avoid replacing an existing service in that
|
|
location
|
|
@param adapter= (sasjs) the macro uses the sasjs adapter by default. To use
|
|
another adapter, add a (different) fileref here.
