RE: Sequence Generator
|
| Sequence generator transformation is basically used to generate a unique number for each record which is updated or inserted in the target table. Also it is used if we want to create a unique key in the table and on the basis of this unique key we are going to identify the record within the table. this is the same as the concept of primary key of the table. |
