Re: SQL UDF...why do i need to qualify the UDF and the table being used?

I always run sql in *SYS naming convention. Then I can create the
function and run select statements without qualifications. However, if you
plan on using *SQL I believe you may want to look at SET PATH(?) before
creating the UDF.

I'm new to UDF's. I've found examples on creating and using external
UDF's but this example uses just SQL.

My function is defined as:

CREATE FUNCTION library.MaxSEQupv
(parm1 char(10),
parm2 dec(8,0))
RETURNS dec(3,0)
LANGUAGE SQL
BEGIN
RETURN(select
cast(max(field3) as decimal(3,0))
from library.table
where field1 =
parm1 and field2 <= parm2);
END

In order to get it to work, I needed to qualify the table. I would prefer
to make this schema independent.

I tested using:

select library.MAXSEQUPV(cast('3434343434' as char(10)),
cast(20120301 as decimal(8,0)))
from sysibm.sysdummy1

again...in order to get it to work, I had to change over to *SQL rather
than *SYS for naming conventions and had to qualify the UDF. Again, I
would prefer to make the UDF schema independent.

What have I done wrong?
