It might be easier to control the authority to the object rather than
those commands, Hopefully the commands are already secured so only
developers can CRTBNDRPG for example. But if those developers should not
be able to touch your function, I'd look at the authority settings on the

RE: Security for SQL functions

A couple of ideas...

On the IBM i a function is an object. Objects can be secured. Secure
your system so only selected individuals can CREATE and/or DROP objects.
This may mean restricting who can use some of the CRTxxxxxxx (CRTBNDC,
CRTBNDCPP, CRTBNDRPG, etc) commands.

For external products using ODBC/JDBC you can use an exit program to
interrogate inbound SQL strings for the functions you want to restrict and
reject the transaction if the user isn't authorized to the function(s).

I am getting ready to put my first SQL user defined function into
production. I just discovered that apparently anyone can create a
function and also, anyone can drop a function. How do I secure my
production functions so that only certain people can drop them?
