Insert Data Error WebDynpro MAXDB

Question

Hi
I have a table in MAXDB which uses a Sequence to generate
unique nos for the records.
CREATE SEQUENCE  Z_DOCU_EXCHANGE_SEQ
START WITH 1
INCREMENT BY 1
When i run a insert statement through SQL Studio the record gets inserted properly.
INSERT INTO Z_DOCU_EXCHANGE VALUES(Z_DOCU_EXCHANGE_SEQ.NEXTVAL,
'A','B','C')
when i try the same through WebDynpro the record does not get inserted.
i am using the following String
String strInsert="INSERT INTO Z_DOCU_EXCHANGE VALUES(Z_DOCU_EXCHANGE_SEQ.NEXTVAL,'A','B','C')";
Is there any special syntax to use MAXDB Sequence in SQL Statement
through WebDynpro ?

Hi RajendraKumar,
Try using this:
java.sql.PreparedStatement ps =
//Here con is your connection object.
      con.prepareStatement("insert into Z_DOCU_EXCHANGE VALUES " +
                     "(<field1>, <field2>, <field3>, <field4>) " +
                     "values (?, ?, ?, ?)");
try {
   ps.setInt (1, Z_DOCU_EXCHANGE_SEQ.NEXTVAL);
   ps.setString(2, "A");
   ps.setString(3, "B");
   ps.setString(4, "C");
   ps.executeUpdate();
} finally {
   ps.close();
