Problem in Stored Procedure...

Question

Hi All,
I'm using oracle 8. When i run this procedure i'm not getting any value from the 'test' table(though i have values 'yikes', 'foo', 'test'.. in 'test1' table). What could be the reason? Can someone tell where i'm making the mistake?
This procedure will be called from the java.
Thanks in advance.
Code :
CREATE OR REPLACE PROCEDURE test_repl
is
tid number;
dum number := 1;
len number;
temp varchar2(500) := 'yikes foo test test1 test2 test3';
str varchar2(500) := null;
flag boolean := TRUE;
tstr varchar2(500) := null;
tstr1 varchar2(500) := null;
TYPE stab is TABLE OF varchar2(500)
INDEX BY BINARY_INTEGER;
strtab stab;
tctr number := 1;
CURSOR C1 IS
SELECT DISTINCT(WORD_OID)
FROM TEST KT
WHERE EXISTS (
SELECT WORD_OID
FROM TEST1
WHERE WORD_OID = KT.WORD_OID AND
( UPPER(WORD_TEXT) IN (tstr) OR
UPPER(WORD_TEXT) = UPPER(tstr1) )
BEGIN
tstr1 := temp;
SELECT LENGTH(temp) INTO len FROM DUAL;
WHILE flag
LOOP
IF NVL(dum,0) > 0 THEN
SELECT INSTR(rtrim(temp),' ',1) INTO dum FROM DUAL;
IF NVL(dum,0) > 0 THEN
SELECT UPPER(SUBSTR(temp,1,(dum-1))), UPPER(SUBSTR(temp,(dum+1),len))
INTO str, temp
FROM DUAL;
DBMS_OUTPUT.PUT_LINE('str :' | | str);
IF (str IS NOT NULL) THEN
strtab(tctr) := '''' | | str | | '''';
END IF;
tctr := tctr + 1;
ELSE
SELECT UPPER(temp) INTO str FROM DUAL;
flag := FALSE;
DBMS_OUTPUT.PUT_LINE('str :' | |str);
IF (str IS NOT NULL) THEN
strtab(tctr) := '''' | | str | | '''';
END IF;
tctr := tctr + 1;
END IF;
ELSE
flag := FALSE;
END IF;
END LOOP;
BEGIN
flag := TRUE;
tctr := 1;
WHILE flag
LOOP
IF (strtab(tctr) IS NOT NULL) THEN
IF tctr = 1 THEN
tstr := tstr | | strtab(tctr);
ELSE
tstr := tstr | | ',' | | strtab(tctr);
END IF;
tctr := tctr + 1;
END IF;
END LOOP;
EXCEPTION
WHEN OTHERS THEN
NULL;
END;
DBMS_OUTPUT.PUT_LINE('Final string : ' | |tstr);
OPEN C1;
LOOP
FETCH C1 INTO tid;
EXIT WHEN C1%NOTFOUND;
DBMS_OUTPUT.PUT_LINE('TID : ' | | tid);
END LOOP;
CLOSE C1;
EXCEPTION
WHEN OTHERS THEN
DBMS_OUTPUT.PUT_LINE(SQLERRM);
END test_repl;
null

Hmm.... I'm curious, you have an "IN" statement which contains a variable... like you are dynamically creating the 'list'. Have you done this before and had it work?
I think that it actually creates one big string as far as the SQL parser is concerned... not several strings separated by commas like I think you think it is doing... ie...
IN ("'hello','test','123'")
not
IN ('hello','test','123')
I could be wrong....
