Create Null-able numeric column in Derived column component
I use SSIS in SQL Server 2016. I have to create a new column in my DataFlow. I use DrivedColumn component to create this new column. In this case I need a nullable numeric column like below image :
As you can see, I have error in this case.
How can I create null-able numeric in Derived column component?
Solution
In the derived column task there are NULL Functions that you can use if you would like to set a value to NULL. Select the appropriate NULL function that corresponds to the datatype of your column and plug that into your equation.
You can use NULL(DT_CY) if your column is defined as currency.
Example. ([currencyAmount]>0? [currencyAmount]:NULL(DT_CY)
In the Derived Column task Null Functions can be found here:
