RE: Create an SQL function

["David Morris" <dmorris@xxxxxxxxxxxxx>]

Dave,

Yes, I have created quite a few.  The most common reason for what you are 
describing is 
overloading.  How did you define your parameters and how are they being passed? 
 The 
count and type of parameters are used when locating the function.  You have to 
match 
the type exactly, e.g. varchar, char, date, int, etc.  The system defaults are 
varchar, and int 
if you pass a literal.  You can look at the file sysfuncs to see what functions 
are available.  
You can also set your function path using the set path command, but the default 
is *LIBL 
so you should be OK.  Also remember that they run in their own thread, so any 
thread 
restrictions and tuning apply.

No, I'm not talking about stored procedures.  I'm talking about functions
which are created with "CREATE FUNCTION".

Has anyone out there created one?

Dave

     Dave,
     
     Are you talking about stored procedures? Look like you need to 
     register the procedure. 
     
     Here's a procedure I just created this morning:
     
     CREATE PROCEDURE SCANMEMO(IN     CASENUMBER  CHAR(9),
                               INOUT  RC          CHAR(1))
        LANGUAGE RPGLE
        MODIFIES SQL DATA
        EXTERNAL NAME SRCS01/IDR197B
        GENERAL 
        
     There's a brief (but useful) sample in the "Sorcerer's Guide" 
     redbook. I believe there are also samples in the ODBC programmers 
     guide.

I am attempting to create an SQL function.  I can create the function but 
whenever I try to use it, I get the error "SQL0204 - RTVDOW in *LIBL type *N

not found.".
     
I tried creating the function in QGPL and ensured that QGPL was in my 
library list, but still get the same error.
     
The SQL manuals do not have any examples on creating functions using RPGLE 
(which is what I'm using). Any ideas?
     
Thanks,
Dave
