When creating a partitioning function, you can choose a LEFT or RIGHT partition function. The difference between LEFT and RIGHT partitions is where the boundary values will be placed in the partitioning scheme. LEFT partitions (which is the default) include the boundary value in the partition ...

For the two partition functions to be equivalent, the partition functions must have identical range clauses (both must specify either LEFT or RIGHT) and the values clauses must specify the same boundary points. More specifically, the view must meet the following requirements to qualify as a ...
