Difference between Stored Procedure and Function?

-
  • Function are compiled and executed at run time.
  • Stored Procedure are stored in parsed and compiled format in the database.
  • Function cannot affect the state of the database which means we cannot perform CRUD operation on the database.
  • Stored Procedure can affect the state of the database by using CRUD operations.
  • Store Procedure can return zero or n values whereas Function can return only one value.
  • Store Procedure can have input, output parameters for it whereas functions can have only input parameters.
  • Function can be called from Stored Procedure whereas Stored Procedure cannot be called from Function.

This transformation unions two datasets/tables.The merge Transformation combines two  sorted  dataset into single dataset. Highlighted the text SORTED in last statement because “It is not possible to use MERGE when the inputs are NOT SORTED”. There is one more transformation which is very similar to this i.e UNION ALL. The Merge Transformation is similar to the union all transformations. Use the union all transformation instead of the merge transformation in the following situations. The transformation inputs are not sorted The combined output does not need to be sorted. The transformation has more than two inputs. MERGE takes ONLY TWO inputs where as UNION ALL can take more than two. Now lets see how to configure MERGE transformation with an example. I created TWO tables with names MergeA and MergeB and inserted few records into each table as shown below.
