Answer / pricil kurian
Types of merges:-
1)one to one merge- It is the merge without any by variables
2)Match merges- Where we are using by variables.
Under match merge we have 1-1 , 1-many, and many-many
depending on the values in by variables.
For many-many merge proc sql will be relaiable.
Please correct me if I am wrong.
