To generate an ID in Oracle, you can use the SEQUENCE feature. First, you need to create a sequence using the CREATE SEQUENCE statement. You can specify the starting value, increment value, and other properties of the sequence.Once the sequence is created, you can use the NEXTVAL function to generate a new ID each time it is called. For example, if you have a sequence named my_sequence, you can generate a new ID by calling my_sequence.NEXTVAL.
