  Hi

  I have been trying to shrink a SQL 7 database for a week now.

  The database size is 63 GB and the data size is 29 GB .

  I rebuild a 7.5 Gb index every weekend .....the fragmentation of the database is in good condition ..all tables and indexes fragmentation stats doesn't exceed 5 % logical fragmentation and the scan density is 90 % or higher .

  What can I do to get the free space back to the system ?

  - how many rows get into a single datapage ?

  - you could rebuild the clustering indexes.

  - If you have tables that consume a huge amount of space and do not have a clustering index ?  Put a clustering index on them ! (if you don't know which columns to pick, choose a increasing number column or a datetime column. If you can, use a unique column. You might even drop/create an existing index)

  I have seen a lot of space wasted with heaps in sql7. Now our default is to put a clustering index on all tables for OLTP. With OLAP other strategies are in use.
