Scenario:
We have requirement to create a package that can create output file dynamically from View/Table.
The columns of View/Table can change anytime but we don't want to open package and remap column/columns.
Solution:
Step1 :
Create the following variables as shown in picture, The values for the variables can be configured by using SSIS configuration,
This will give us freedom to change the name of file,directory path,Delemiter("," or "" etc) and file extension(txt or csv etc)
![]()
Step2:
After creating variable, Drag Execute SQL Task in control flow pane and configure as show in picture
![]()
![]()
Step3:
Drag Script task in Control Flow Pane and configure as show in picture
![]()
Step4:
Click on Edit Script button, paste following code and save the the changes and Finally OK button.
Note: I have "*" in the query , so if any new column/columns will be addeds to Table or view, my output file will get data for all the columns
and I don't have to change anything.
