You are developing a data flow transformation to merge two data sources. One source contains product data
and the other source contains data about the country in which the product was manufactured. Both data
sources contain a two-character CountryCode column and both use SQL Server. Both data sources contain an
ORDER BY clause to sort the data by the CountryCodecolumn in ascending order. You use a Merge Join
transformation to join the data.
You need to ensure that the Merge Join transformation works correctly without additional transformations. What
should you do? (Each answer presents a part of the solution. Choose all that apply.)
A.
Set the appropriate SortKeyPosition properties onthe data sources.
B.
Set the ValidateExternalMetaData property on the Merge Join transformation to True.
C.
Set the IsSorted property on both data sources.
D.
Set the MaxBuffersPerlnput property on the Merge Join transformation to 2.
