How to include Primary ID column using SSIS package?

Question:
I have target table where columns are ID, Name & DateofBirth where ID is PK and should be increment of 1(eg. 1, 2, 3, 4... and so on) also NOTE that ID column is NOT AN IDENTITY column

Now I have flat file which has data with only Names & Dateofbirth.

Answer:
Hi, There are two ways.

First:: Download the "Row Number Transformation" and use it in your SSIS package.

The Row Number Transformation calculates a row number for each row, and adds this as a new output column to the data flow. The column number is a sequential number, based on a seed value. Each row receives the next number in the sequence, based on the defined increment value.

Second:: Add a "Script Component transformation" and write a script there for adding the row numbers. Please check the "Row Numbers in a DataFlow"for step-by-step explanation.
