SELECT TABLE_ID, ISN, MAP_NAME FROM REFRESH_LOG ORDER BY TABLE_

Known Optimizer Plan(s) for this Old Hash Value
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Shows all known Optimizer Plans for this database instance, and the Snap Id's
they were first found in the shared pool. A Plan Hash Value will appear
multiple times if the cost has changed
-> ordered by Snap Id

Plans in shared pool between Begin and End Snap Ids
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Shows the Execution Plans found in the shared pool between the begin and end
snapshots specified. The values for Rows, Bytes and Cost shown below are those
which existed at the time the first-ever snapshot captured this plan - these
values often change over time, and so may not be indicative of current values
-> Rows indicates Cardinality, PHV is Plan Hash Value
-> ordered by Plan Hash Value
--------------------------------------------------------------------------------
| Operation | PHV/Object Name | Rows | Bytes| Cost |

|SELECT STATEMENT |----- 826343889 -----| | | 967 |
