primarky key column in target table adf

Question

How to handle data when primary key(1,2,3- auto increament) column has no value in column in the source

how to match when column is not available for the same in source

Answer 1

Since the target table's primary key is auto-incremented, you don't need to provide a value for this column during the insert operation. The database will automatically handle the primary key values.

Here is an example of how the Data Flow mapping might look:

• Source Columns: ColumnA, ColumnB, ColumnC
• Target Columns: ID (auto-increment), ColumnA, ColumnB, ColumnC

In the Data Flow, the mapping would be:

• ColumnA -> ColumnA
• ColumnB -> ColumnB
• ColumnC -> ColumnC

The ID column in the target table will automatically generate unique values for each row inserted.
