Hi,
If you find out that the number of page splits is high, consider increasing the fillfactor of your indexes. Why this so? What does a fill factor of 50 mean as compared to a fillfactor of 80. How is one better than the other in case of page splits.

Bye

If you look in Books Online under "fill factor" you'll find an excellent explanation of page splits and fill factor. Also look under DBCC SHOWCONTIG and DBCC DBREINDEX.

When a page is full it will be split into 2 so slowing down the insert/update and fragmenting the table.
The fill factor specifies how full each index page should be on index creation.
The lower the fill factor the more space available, less likely to page split but needs more reads to access.

Cursors are useful if you don't know sql.
DTS can be used in a similar way.
