SQL Server 2012 CTE Bug? -


i think found bug in sql server 2012. have following complex query uses cte row_number accomplish paging, followed subquery return total rows in single query:

with data ( ...complex query row_number() ... rownumber... ) select *, (select count(*) data) totalrows  data rownumber between 1 , 10

what i'm finding in specific query if final query returns 5 rows, totalrows comes 8. there 5 rows. how totalrows bigger number of rows returned? i've tried query hints disabling parallel execution plans not slower, it's still not right. doing wrong or bug? there way count in 1 query?

without knowing internals of query , ensuring you're partitioning statements written...

i'd suggest getting differences because of clauses. need consistent , use either:

with data ( ...complex query row_number() ... rownumber... ) select *, (select count(*) data rownumber between 1 , 10) totalrows  data     rownumber between 1 , 10

or

with data ( ...complex query row_number() ... rownumber... ) select *, (select count(*) data) totalrows  data
