ORA 01840 error

Question

So much has been written about this error and I have followed some of the suggestions:
Here's the problem:
Field in the database is recvddate and the datatype is varchar2(10)
When I write the following procedure and pass the date parameter, I get the error:
ORA-01840: input value not long enough for date format
CREATE OR REPLACE Procedure test55
( startdate IN varchar2,
enddate IN varchar2)
AS
BEGIN
SELECT col1, col2
FROM table1
WHERE recvddate
BETWEEN to_date( &startdate, 'yyyy-mm-dd')
AND to_date(&enddate,'yyyy-mm-dd');
END;
This is how I pass the parameters:
Enter value for startdate: 2007-01-02
Enter value for enddate: 2007-01-29
Thanks a lot

Answer 1

Put a single quote around the Date and it should work.
You may need to modify your procedure as "SELECT col1, col2 " should be defined.
Wrote file afiedt.buf
1 CREATE OR REPLACE Procedure test55
2 ( startdate IN varchar2,
3 enddate IN varchar2)
4 AS
5 l_num NUMBER(2);
6 BEGIN
7 SELECT COUNT(*) INTO L_num
8 FROM t1
9 WHERE recvddate
10 BETWEEN to_date( &startdate, 'yyyy-mm-dd')
11 AND to_date(&enddate,'yyyy-mm-dd');
12* END;
SQL> /
Enter value for startdate: '2007-01-02'
old 10: BETWEEN to_date( &startdate, 'yyyy-mm-dd')
new 10: BETWEEN to_date( '2007-01-02', 'yyyy-mm-dd')
Enter value for enddate: '2007-01-02'
old 11: AND to_date(&enddate,'yyyy-mm-dd');
new 11: AND to_date('2007-01-02','yyyy-mm-dd');
Procedure created.
