What prepared statement can do?

Question

Hello I got this question:
Normal usage of PreparedStatement goes like this:
PreparedStatement pstmt = con.prepareStatement("UPDATE EMPLOYEES SET SALARY = ? WHERE ID = ?");
pstmt.setBigDecimal(1, 153833.00)
pstmt.setInt(2, 110592)
My problem is how can I use it for INSERT statement??
e.g. I want to do something like this:
PreparedStatement pstmt = con.INSERT INTO TABLE_A VALUE('?','?','?',?);
byte[] bytes;
pstmt.setString(1, "1234");
pstmt.setBytes(2,bytes);
but I got an error for that..so I suspect my usage is somehow wrong. Can someone teach me how to do this kind of insertion using preparedStatement?
Thanks,

HI Bvsp_Indian,
thanks for the insertion part and it works, however, when I try to retrieve the same bytes it gives me this error
Error: JZ0TC: Attempted conversion between an illegal pair of types.
java.sql.SQLException: JZ0TC: Attempted conversion between an illegal pair of ty

My codes on how to retrive the result set goes like this:
String strSelect = "SELECT * FROM testing where NAME_CUSTOMER = 'Thomas'";
java.sql.ResultSet rs1 = stmt.executeQuery(strSelect);
while (rs1.next()) {
String name = rs1.getString("NAME_CUSTOMER");
String age1 = rs1.getString("AGE");
//String credit_no = rs1.getString("CREDIT_NUMBER");
// this is the column that i want to retrieve to its bytes[]
byte[] secret = rs1.getBytes("SECRET");
System.out.println("THE SECRET IS " + secret);     
How can I retrieve back the bytes[] that i just stored??
Thanks in advance,
