Re: SQL UDF and *LIBL

[rob@xxxxxxxxx]

I did this:

CREATE TABLE ROB/ADAM (MYKEY CHAR (1 ) NOT NULL WITH DEFAULT,
MYDATA CHAR (2 ) NOT NULL WITH DEFAULT) 

INSERT INTO ROB/ADAM VALUES('A', 'B') 

CREATE TABLE ROB/ADAM2 (MYKEY CHAR (1 ) NOT NULL WITH DEFAULT,
MYFIDL CHAR (33 ) NOT NULL WITH DEFAULT) 

INSERT INTO ROB/ADAM2 VALUES('A', 'DUH')

CREATE FUNCTION QGPL/GETADAM (INFLD CHAR (1))
RETURNS CHAR (1) 
LANGUAGE SQL 
READS SQL DATA 
DETERMINISTIC 
RETURNS NULL ON NULL INPUT 
BEGIN 
DECLARE OUTFLD CHAR(1); 
SET PATH = *LIBL; 
SELECT MYDATA INTO OUTFLD 
FROM ADAM 
WHERE MYKEY=INFLD; 
RETURN OUTFLD; 
END -- GETADAM; 

SELECT MYKEY, GETADAM(MYKEY)
FROM ROB/ADAM2 

....+....1....+....2....
MYKEY  GETADAM ( MYKEY )
  A            B 
********  End of data  *

I've created some SQL user defined functions (UDF) that I am using in my 
embedded SQLRPGLE programs.  I am having a problem that the UDF will not 
use my *LIBL.  In my regular embedded SQL I do not need to specify the 
library that contains the file; It uses my LIBL.  The function however is 
forcing me to HARDCODE the library in order to work correctly.   Anybody 
know what I'm doing wrong?

Below is the code fro the function and the SQLRPGLE program at V5R2:

CREATE FUNCTION GETCEN  (pYear Decimal (2,0)) 
Returns Decimal(2,0) 
Language SQL 
Reads SQL Data 
Deterministic 
Returns Null On Null Input 

Begin 
 Declare wCenturyBaseYear Decimal(2,0); 
 Declare wLowCentury Decimal(2,0); 
 Declare wHighCentury Decimal(2,0); 
 Declare pCentury Decimal(2,0); 

Set Path = *LIBL;

Select SYBSYR, SYLCEN, SYHCEN 
 Into wCenturyBaseYear, wLowCentury, wHighCentury 
 From MYFILE 
 Where SYCO = 01 and SYID = '  '; 

If wCenturyBaseYear IS NULL Then 
  Set wCenturyBaseYear = 85; 
  Set wLowCentury = 19; 
  Set wHighCentury = 20; 
End If; 

If pYear > wCenturyBaseYear Then 
 Set  pCentury = wLowCentury; 
Else 
 Set pCentury = wHighCentury; 
End If; 

Return pCentury; 

End -- GETCEN;


Below gives me an error at runtime that "MYFILE in MYLIB(which is my 
CURLIB) type *FILE not found" even though MYFILE is in my LIBL.
 * 
C/EXEC SQL 
C+ SET :@CENT = GETCEN(:@YEAR) 
C/END-EXEC
