Toad for Oracle 15.0 not only provides enhanced desktop security and support for Oracle Database 21c but, as a part of Quest’s ongoing commitment to expand its Toad SaaS portfolio, now includes Xpert Plus Edition Subscription that adds SQL performance tuning, database administration and sensitive data protection. With version 15.0 generally available today, Toad for Oracle customers are now further empowered to reduce threats from cyber-attacks, with new rigorous and comprehensive secure software development life cycle (SSDLC) controls. | 2 | INDEX FAST FULL SCAN| SYS_C0033689 | 1 | 4 | 4 |00:00:00.Quest Software, a global systems management, data protection, and security software provider, today announced major updates for Toad® for Oracle, an intuitive database management toolset that makes it easy to perform essential database development and administration tasks. | Id | Operation | Name | Starts | E-Rows | A-Rows | A-Time | Buffers | To get this information either you need to add the gather_plan_statistics hint or set statistics_level to ALL.ĭoing this in SQL Developer and running in script mode I see:Īlter session set statistics_level = all Without this information, it's tough to know if the plan is 'good', even if you're seeing the actual plan used. The best way to be sure it's the 'real' plan is to see if the A(ctual)-rows, A(ctual)-time, buffers, columns etc. So 'explain plan' and 'autotrace' can be misleading. I didnt use the index because my data types didn't match. SQL> select * from table(dbms_xplan.display_cursor)

Let's see what *really* happens when I run it: So based on that, I might think my query is fine. Predicate Information (identified by operation id): egĢ select d.*, cast(object_id as varchar2(20)) abc The issue is that they are not always a realistic view of what will actually take place. Just remember: it is an estimate and only granular to one second! | Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time | Note you need to multiply the values in the 'starts' column to those in the 'estimated' to get the value to compare to actual rows.įinal note: if you're trying to get the estimated time, explain plans include this: Then compare the estimates to the actuals and see if they're close.

This shows you the number of rows processed. To figure this out, you need the execution plan. If the answer is yes for all steps of the plan, it's likely you have the 'best' plan for your query. 'Is the (estimated) cardinality roughly equal to the actual number of rows the statement processed?' The cost is useful for figuring out why the optimizer chose (e.g.) a full table scan over an index. A lower cost query can run faster than a higher cost one! Thus the cost is (usually) higher.Īll other things being equal, a query with a higher cost will use more resources and thus take longer to run. Cardinality is the estimated number of rows the step will return.Ĭost is the estimated amount of work the plan will do.Ī higher cardinality => you're going to fetch more rows => you're going to do more work => the query will take longer.
