I have a mapping that gets data from multiple sql server source tables and assigns a sequence generated number as ID for each rows. In the target table, the ID field is set as primary key.
Every time I run this mapping, it creates new rows and assigns a new ID for the records that are pre-existing in the target. Below is an example:
1st run:
ID SourceID Name State
1 123 ABC NY
2 456 DEF PA
2nd run:
ID SourceID Name State
1 123 ABC NY
2 456 DEF PA
3 123 ABC NY
4 456 DEF PA
Desired Output must: 1) create a new row and assign a new ID if a record gets updated in the source. 2) create a new row and assign a new ID if new rows are inserted in the source.
How can this be obtained in Informatica?
Thank you in advance!
