Re: [EXTERNAL] Re: Mixing sql and service program in IWS...

Just throwing this out as a possibility...I have never done this and have no clue about performance, limitations, or complexity in troubleshooting.

Would it be possible to create a *stored procedure* that calls the desired ILE program? I know stored procedures can call ILE programs. I've seen other people do it in our shop.

Then, use IWS to create a single REST service (SQL type service). The REST service would contain two methods within it. 
(1.) One method receives HTTP GET requests and executes the SQL statement against the database file or table (e.g., SELECT * FROM MYFILE). 
(2.) A second method receives HTTP POST requests and executes a SQL CALL statement to call the stored procedure--which in turn calls the desired ILE program. 

Thanks,

Rob, no you  cannot.  But if  you use an HTTP server you can always play with URL mapping so from the point  of view of clients it  does  look like it is the same  resource.  In admin  and  programming  guide there is some  examples of URL mapping, although not related to this issue but would be a solution to what you want to achieve.
