Using SEQUENCE in a Java servlet
How do I use SEQUENCE for a column when I am issuing an INSERT command? I am using the command in a JAVA servlet.
With each sequence, there is a psuedo-column called NEXTVAL. This gets the sequence's next value. Assume I have a sequence called MY_SEQ. Then to insert a value into a table, I might use a statement like this:
INSERT INTO my_table VALUES (my_seq.NEXTVAL, 'bob');When Oracle sees "my_seq.NEXTVAL" it gets the next value from the sequence and automatically updates the sequence counter for the next transaction.
