Error in preparedstatement

Question

Hi
Is this preparedstatement valid
INSERT INTO TABLE2 (COL1,COL2,COL3,COL4)
SELECT C1,C2,?,? FROM TABLE1 WHERE condn
When I do con.prepareStatement() on this sql it is giving me error saying
"Use of parameter marker not valid"
Is this wrong??

Is this preparedstatement valid

SELECT C1,C2,?,? FROM TABLE1 WHERE condnOn oracle, that PreparedStatement will compile, but setting the parameters to the column names does not produce the expected result. The Strings are treated as constants, not as column names.
If you set the parameters like this.
pstmt.setString(1,"C3");
pstmt.setString(2,"C4");
You get the effective SQL being
INSERT INTO TABLE2 (COL1,COL2,COL3,COL4)
SELECT C1,C2,'C3','C4' FROM TABLE1 WHERE condn
Could be different on other DBs.
