Does this help? http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:6978 972926020 -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Eriovaldo Andrietta Sent: Friday, August 17, 2012 8:34 AM To: ORACLE-L Subject: Function - return Deterministic Hi Friends, I am in trouble with this resource. 1.) The function F_TESTE_DETERMINISTIC works fine as the concept of DETERMINISTIC. It executes once. CREATE OR REPLACE FUNCTION F_TESTE_DETERMINISTIC (PARAMETRO IN NUMBER) RETURN NUMBER DETERMINISTIC IS BEGIN DBMS_OUTPUT.PUT_LINE ('RETORNO : ' || PARAMETRO); RETURN PARAMETRO; END; set serveroutput on SELECT ROWNUM N, teste (1), DBMS_RANDOM.STRING ('X', 16) FROM dual CONNECT BY LEVEL <= 10; N TESTE(1) DBMS_RANDOM.STRING('X',16) ---------- ---------- ------------------------------------------------------------------------ -------- 1 1 24CRBOWA1RG390FZ 2 1 PNJZD51W00Z5Q8HF 3 1 SAAHZS9KDBP9HAP6 4 1 QOH0LBM34BW1WDQT 5 1 1QK8SOJ3Z89UFQ3R 6 1 PG5CJ4JXL6IV6ZEF 7 1 29I9Z89PXQU11QUT 8 1 S1DFH9RNX34ZOYJ1 9 1 IR4FZCHM70DKUDQD 10 1 8WBO9530DN8O6TRG foo : 1 10 rows selected 2.) But , using the return SDO_GEOMETRY as below, it does not happen. It calls 10 times the function. CREATE OR REPLACE FUNCTION point (x in NUMBER, y in NUMBER, srid in NUMBER DEFAULT 8370) RETURN SDO_GEOMETRY DETERMINISTIC IS BEGIN DBMS_OUTPUT.PUT_LINE ('x = : ' || x || ' y = ' || y); RETURN SDO_GEOMETRY (2001, srid, SDO_POINT_TYPE (x,y,NULL), NULL, NULL); END; / SQL> select point (1,2) from dual 2 CONNECT BY LEVEL <= 10; POINT(1,2) ---------- <Object> <Object> <Object> <Object> <Object> <Object> <Object> <Object> <Object> <Object> x = : 1 y = 2 x = : 1 y = 2 x = : 1 y = 2 x = : 1 y = 2 x = : 1 y = 2 x = : 1 y = 2 x = : 1 y = 2 x = : 1 y = 2 x = : 1 y = 2 x = : 1 y = 2 10 rows selected Why does it happen ? The DETERMINISTIC does not works with SDO_GEOMETRY ?
