2) Using a sequence in a table column example Prior to Oracle 12c, you could associate a sequence indirectly with a table column only at the insert time. See the following example. First,create a new tablecalledtasks: CREATETABLEtasks(idNUMBERPRIMARYKEY, titleVARCHAR2(255)NOTNULL);Code langu...

Question: How do we set the LASTVALUE value in an Oracle Sequence? Answer: You can change the LASTVALUE for an Oracle sequence, by executing an ALTER SEQUENCE command. For example, if the last value used by the Oracle sequence was 100 and you would like to reset the sequence to serve ...

NOTE: The alternative to sequences used in other RDBMS products is autonumbering and keeping the current number in a table. Both of these other methods demand serialization as they can only dispense one number at a time.Table example:
Oracle uses the concept of SEQUENCE to create numerical primary key values as we add rows of data into a table. Whereas numerical primary key population for MySQL and SQL Server is tied to individual tables, in Oracle the SEQUENCE construct is created separately and is not tied to an individu...
