In this video we will do perform some experiments to understand following
What is Full Cache Mode in Lookup Transformation and How it works in SSIS Package
What is Partial Cache Mode in Lookup Transformation and How it works in SSIS Package
What is No Cache Mode in Lookup Transformation and How it works in SSIS Package
we will use SQL Server Profiler to capture live SQL Statements to while changing the mode from Full Cache to Partial or from Partial Cache to No Cache.
Sample Data used in the Test File
CustomerId,CustomerName,StreetAddress,City,State,RegionCode
1,Aamir,1234 Street,Sahiwal,NY,NA
1,Aamir,Test Address,Charlotte,NC,NA
