- The generation of unique numeric values by a special type of object either in ascending or descending order is called sequence.
- It is frequently used in
databases as many applications require unique value in a row. - Its functionality is same as the Autonumber data type in MS access.
- For example, both the sequence and Autonumber data type generate ascending or descending values.
There are some slight difference which occurs between sequence and the Autonumber data type. Some of the differences are listed below:
- In MS Access, Autonumber is just a data type, whereas in oracle, sequence is completely an independent object.
- In MS Access, only one Autonumber is given for a table, whereas in Oracle, many sequences can be given to any number of tables...
