My that's one heck of an email address.
Basic answer here. A function must return a value. Put it in an anonymous block, return it's value to a variable and output it. Then you'll see what you expect.
The other question is why are you using a cursor? That's not necessary here.
I'd do something like
SELECT lname FROM names INTO var_name WHERE laname = &var and rownum < 2;
RETURN true;
EXCEPTION
WHEN no_data_found RETURN FALSE;
END;

Hi again everybody,
I'll try to be as descriptive as possible, sorry if I leave anything important out.
I have the following function which I'm compiling using PL/SQL Developer (tnx Djordje).
CREATE OR REPLACE FUNCTION check_for_name (
p_name_to_check VARCHAR)
RETURN BOOLEAN IS
CURSOR c_namestbl IS
SELECT lname
FROM names
WHERE lname = p_name_to_check;
v_return_value BOOLEAN;
BEGIN
OPEN c_namestbl;
IF c_namestbl%NOTFOUND THEN
v_return_value := FALSE;
ELSIF C_namestbl%FOUND THEN
v_return_value := TRUE;
END IF;
RETURN v_return_value;
CLOSE c_namestbl;
END check_for_name;
It compiles without errors (now).
The table 'names' is built like this :
SVRMGR> DESCRIBE names;
Column Name Null? Type
------------------------------ -------- ----
FNAME VARCHAR2(20)
LNAME VARCHAR2(20)
SVRMGR>
With data like this :
SVRMGR> SELECT * FROM names;
FNAME LNAME
-------------------- --------------------
Bruce Willis
Salma Hayek
Tom Cruise
Elle McPherson
4 rows selected.
But, whenever I try to do this :
EXECUTE check_for_name('Cruise');
so I can run the function from PL/SQL Developer I get the following error :
"ORA 0900 - Invalid SQL Statment"
However, If I execute the same statement from SQL*Plus or svrmgrl I get a differant error :
SVRMGR> EXECUTE check_for_name('Cruise');
check_for_name('Cruise');
*
ORA-06550: line 2, column 2:
PLS-00221: 'CHECK_FOR_NAME' is not a procedure or is undefined
ORA-06550: line 2, column 2:
PL/SQL: Statement ignored
I'm running Oracle Enterprise Edition 8.1.5.0.0 on Windows 2000.
If that's not enough info, please let me know and I will supply whatever I can.
Thanks for reading this far :)
Michael.
