SetString(1,"TO_DATE('2004-01-17','YYYY-MM-DD')"); Will that work

Question

Hi all,
Can you tell me whether I can have whole SQL sections in my setXXX methods when
using PreparedStatements?
setString(1,"TO_DATE('2004-01-17','YYYY-MM-DD')");I thought I had my program working with such a statement, but now when I try it
it doesn't work but rather give me the following error:
ORA-01858: a non-numeric character was found where a numeric was expected
SQL would be i.e. "INSERT INTO myTest (myDate) VALUES (?)"

Answer 1

Something peculiar I found was this:
In my pstmt's SQL is the following:
INSERT INTO myTable (myInt,myDate) VALUES (?,TO_DATE(?,'YYYY-MM-DD'))
pstmt.setString(1,'1'); //for the int using Oracle for converting
pstmt.setString(2,'2005-01-17'); // this what I would normally use
But I had run into problem where myDate was supposed to be NULL,
that's why I posted the initial question about putting SQL into the setXXX
statement. But, what I found was that I could instead also put in a setDate
in place of the setString:
pstmt.setDate(2,null); // This will work even though I have the TO_DATE
Why would that be? Will the pstmt simply ignore the TO_DATE statement?
