Question

Working with an Oracle 9i database from an ASP.NET 2.0 (VB) application using OLEDB. Is there a way to have an insert statement return a value? I have a sequence set up to number entries as they go into the database, but I need that value to come back after the insert so I can do some manipulation to the set I just entered in the code-behind VB.

Answer 1

Some possibilities:

1) Use the RETURNING clause:

INSERT INTO emp (empno, ename) VALUES (emp_seq.NEXTVAL, 'ANDREWS') RETURNING empno INTO :variable; 

2) Use the sequence CURRVAL:

INSERT INTO emp (empno, ename) VALUES (emp_seq.NEXTVAL, 'ANDREWS'); SELECT emp_seq.CURRVAL INTO :variable FROM DUAL; 

CURRVAL returns the last sequence value generated by your session.
