The number of pages in the leaf level of an index depends on the number of rows and the size of the rows (again, in terms of bytes) of the rows in the leaf level. Poor page density reflects that your pages are not as full as they could be but there are many factors for why this is the case: bad row size, splits due to inserts, splits due to updates of varchar columns or even a poorly chosen fillfactor that has left too much space on the pages

) GO While this table structure is excellent when you need to know the employee's supervisor, it's not very helpful when you need to move further up the tree. If you were building an inventory catalog, you might find this more useful than in an HR system, as the top of each category tree would be its own root
Temporary tables in SQL Server vs. table variables
On a heavy load system that has lots of usage of temporary tables, the disk array servicing the tempdb database will experience a higher than expected load. Creating indexes on SQL Server tables Because both local and global temporary tables are physical tables within the tempdb database, indexes can be created on these tables to increase performance as needed

SQL Server : Creating an index on a table variable - Stack Overflow
If not explicitly specified otherwise the PRIMARY KEY will become the clustered index and unique constraints non clustered but this behavior can be overridden by specifying CLUSTERED or NONCLUSTERED explicitly with the constraint declaration (Example syntax) DECLARE @T TABLE ( A INT NULL UNIQUE CLUSTERED, B INT NOT NULL PRIMARY KEY NONCLUSTERED ) As a result of the above the following indexes can be implicitly created on table variables in SQL Server 2000 - 2012. Otherwise for the non unique case SQL Server adds the row locator (clustered index key or RID for a heap) to all index keys (not just duplicates) this again ensures they are unique

In earlier versions of SQL SERVER it is not possible to pass a table variable in stored procedure as a parameter, but now in SQL SERVER 2008 we can use Table-Valued Parameter to send multiple rows of data to a stored procedure or a function without creating a temporary table or passing so many parameters. Is there any thing similar to this, that can be used from Application layer side in java language with SQL Server 2008? This is very urgent requirement, can some one help? Thanks, Swetha
