You are loading a file into a database but the file name is unknown at design time and will have to
be passed dynamically to a Package at run time; how do you achieve this?
A.
Create a variable, use it in Topology at the File dataserver-level, and add it to a package as a
Declare Variable step
B.
Create a variable, use it in Topology at the File dataserver-level, and add it to a package as a
Set Variable step
C.
Create a variable, use it as the Resource Name of the File datastore, and add it to a package
as a Declare Variable step
D.
Create a variable, use it as the Resource Name of the File datastore, and add it to a package
as a Set Variable step
Explanation:
I think the correct answer is C
I think that the answer is C. Some can explain the answer D please
Thank you
The answer is C, If you use the set variable step, you assign a specific value to a variable wich is not the case, in this case the value is passed to the package and the data store receives that value, the variable must be set as declare mode!
the answer is D
Only C is ‘passed dynamically to a Package’ as required.
D is a defined value, thus not dynamic.
The correct ans is C
Answer is clearly “C”.
We have to declare the variable.
Declare variable is the only type of variable which allows us to pass value at runtime.
