I'm getting above error message when i'm trying to define one cursor from a table which has a column with data timestamp(3) in a cursor i'm not even using a column with data type timestamp .( this tables i created by importing sybase tables into oracle )
SELECT to_char(sysdate) -- trunc(act.date_posted)
INTO v__Data
from cedb.cr_ar_debit_activity act
where rownum < 2 ;
for testing purpose i even removed the cursor and make it shor to above query then also it dosent work and gave the above error . if you know the solution then please let me know . i think i've to do/change database settings but i'm not sure .

Answer 1

the above code is not working but the following code is working if i open cursor from assiging select to variable , why this is happening .
DECLARE
     v_A_REPORT_DT VARCHAR2(100);
ls_sel VARCHAR2(900);
i INTEGER := 1;
TYPE dynamic_cur IS REF CURSOR;
tb_test_cur dynamic_cur ;
TYPE array_date_type IS TABLE OF DATE INDEX BY PLS_INTEGER;
v1 array_date_type ;
BEGIN
     v_A_REPORT_DT := '01-01-2007'/* VARCHAR2(2000) */;
-- this one is not working
SELECT to_char(sysdate) -- trunc(act.date_posted)
INTO v_A_REPORT_DT
from cedb.cr_ar_debit_activity act
where rownum < 2 ;
ls_sel := 'SELECT trunc(act.date_posted)
from cedb.cr_ar_debit_activity act
where rownum < 3 ' ;
OPEN tb_test_cur FOR ls_sel;
LOOP
FETCH tb_test_cur INTO v1(i) ;
EXIT WHEN tb_test_cur%notfound;
dbms_output.put_line(to_char(v1(i)));
i := i + 1 ;
END LOOP;
CLOSE tb_test_cur;
END;
