About size of nvarchar(max)I tried this:
declare @C nvarchar(max)set @C = N'hello' + replicate('-',8000)
print len(@c)
the result was still 4000. Can someone explain why it wasn't more since nvarchar(max) can accept more then 4000
The REPLICATE('-', 8000) has an implicit cast to NVARCHAR, try this to explicitly CAST it to NVARCHAR(MAX):
declare @C nvarchar(max)
set @C = N'hello' + CAST(replicate('-',8000) AS NVARCHAR(MAX))
print len(@c)
you get 8005 as the length.
