| | Assume a table with Unique secondary index, Non-Unique secondary index and a Join index. In case an Update is executed on the table, do the
index sub tables get updated every time when a record gets updated or does it happen at a block level or at a transaction level? Is it the same
for all types of indexes? | |
Amol, try EXPLAIN on your UPDATE statement. It should know more than us.
