RE: Creating a SQL UDF

Thanks Scott.

That did it. I was so focused on a deeper problem that I overlooked the
obvious.

My next guess would be that your parameters don't match, and so you are
corrupting memory. Looking back, I see that your RPG code returns a
65535A, which is larger than SQL could support. Your latest SQL is only
reserving memory for VARCHAR(1000). That means that your RPG will
overwrite 64535 bytes of memory that haven't been reserved to it -- and
that can cause just about any sort of error.

Please make your parameters match.

I tried the "disallow parallel", but still got the same error.

Hi Robert,

I haven't run across this error before, but I suspect it's because
you've coded "allow parallel". This would mean that it's trying to
call your UDF in multiple threads at once. I suspect that your RPG
program is not coded to handle multi-threaded calls.

Try changing it to "disallow parallel" and see if that solves the
problem.

There is nothing else in my joblog, but this message. This is how I
defined my UDF:

Create Function RMULLIS/RmvNonAlph(VarChar(1000),VarChar(1))
Returns VarChar(1000)
Language RPGLE
External Name 'RMULLIS/SYSRVUTL(REMOVE_NON_ALPHANUMERIC)'
Deterministic
No SQL
Parameter Style General
Allow Parallel
No External Action

Any ideas on what might cause this error?
