In SSIS, I already have a Web Service Task using a WSDL for sending SMS. I am indeed able to send SMS using this task.
I want supply values to this task from the database, such as Mobile Number, Message body, User ID, etc.
How can I create a complex type user variable that can be passed as input to a Web Service task?
It looks like the only answer is to change the web service to accept only simple types as parameters. I have scoured the web and there seems to be no way to dynamically create complex types for consumption by the input values in the web service task.
The more 'easy' way is to use the script component for bypassing variables to a web service. Check http://amolpandey.com/2016/09/26/ssis-script-task-to-obtain-geo-cordinates-from-address-text-via-google-api/ & http://www.sqlmusings.com/2011/03/25/geocode-locations-using-google-maps-v3-api-and-ssis/.
Tested and working. Using this task you can bypass the SSIS variables/parameters.
Example: Getting ID, addreess, zipcode, city, country from a table with an execute SQL Task. Change Resultset:Full result set on General tab. Then on resultset tab add Result_Name:0 & Variable_Name: User::YourObject. Then the next task will be a Forlooptask editor (Foreach ADO Enumerator ,Collection tab - Ado object source variable: User::YourObject, enumeration mode: rows in the first table, variable Mapping tab - Variable User::Id, 0 | address,1 etc.). Inside the Forlooptask editor you add a data flow task, which the source of this task will be a script component. If you be more specific about your logic,we may assist you more.
