Dear Friends1-1-How to know the fragmentation size for whole database not only for certain table, to decide if it exexceeds 30% to re-build index or re-organise.
2-what is the relationship between re-build or re-organise index by log file.
Thanks lot
1) Fragmentation for the database as whole doesn't make sense in this context. You need to look at each index individually.
2) I don't understand your question here. What do you mean?
You should probably do a google search for "sql server rebuild vs reorganize index" and be prepared to spend some time reading.
