Hi Ramesh,
| Key Generation Transform |
Row Generation Transform |
|---|---|
Generates new keys for source data, starting from a value based on existing keys in the table you specify | Generates a column filled with integer values starting at zero and incrementing by one to the end value you specify. |
It generates the increment value based on the generated key column filed. For example if you want to generate a Surrogate Key Column to avoid duplicate it will generate the key based on the increment 1 followed by the preceding value. | It generate value based on Row Number Starts at and Row Count.
For example if you want to insert a new row in the table by using row generation you can generate a new row in the target table. |
| It cannot be used as a source. It need input field to return value | It can be used a source filed to generate output column |
