Customizing DML of Entity Object

Question

Hi,
I use Oracle ADF 12.1.3 with MS SQL Server as back-end database. Codes below demonstrate the situation.
@Override
protected void doDML(int i, TransactionEvent transactionEvent) {
super.doDML(i, transactionEvent);
if (i == DML_INSERT) {
Long id = null;
Statement stmt = this.getDBTransaction().createStatement(0);
try {
(1) ResultSet res = stmt.executeQuery("select @@IDENTITY as pk_num");  =>> WORKS
(2) ResultSet res = stmt.executeQuery("select SCOPE_IDENTITY() as pk_num");  =>> DOES NOT WORKS RETURN 0;
(3) ResultSet res = stmt.executeQuery("insert into uOstan (Nam, Cod) values ('_Test_', '_123_') select SCOPE_IDENTITY() as pk_num"); =>> WORKS
if (res.next()) {
id = res.getLong("pk_num");
populateAttribute(0, id);
} catch (Exception e) {
System.out.println(e.getMessage());
According of above lines of code, I think there is a bug in JDBC. Because of this, I want to customize the ADF auto generated dml statement for EO and add 'select scope_identity() as pk_val' at the end of it to get the correct value of pk of inserted row.

What do y o u mean by '... Does not work' exactly?
Do you get an error?
The code you call in the statement looks out of scope to me. It is executed in the DB which can't know what to do with it.
The other statements work as  they are normal insert wavelengths db can handle.
