I have a large table which is (left) partitioned into three monthly segments :-

31/03/2009, 30/06/2009, 30/09/2009, 31/12/2009
31/03/2010, 30/06/2010, 30/09/2010, 31/12/2010
31/03/2011, 30/06/2011, 30/09/2011, 31/12/2011
31/03/2012, 30/06/2012, 30/09/2012, 31/12/2012

If I want to merge older data into bigger partiions and i run the following:-

ALTER PARTITION FUNCTION fn_mypartitionfunction()
MERGE RANGE ('31/03/2010')

I assume the data pre this date would all be merged into that quarter?

Now if i ran this code after

ALTER PARTITION FUNCTION fn_mypartitionfunction()
MERGE RANGE ('31/03/2011')

would the initial merge be swallowed up into one large dataset '31/03/2011' or would it reatin my original merge of '31/03/2010' giving me two large datasets?

No the data will be merged into a larger dataset with range starting from '31/03/2011'

After Monday and Tuesday even the calendar says W T F ....
