XPLAN PLAN

Use the following to setup an explain plan table for a database.

I tested this using 10.2.0.2 so the plan table may differ, but theory should be the same from 9i onwards.


drop table plan_table;
create global temporary table plan_table(
statement_id varchar2(30),
plan_id number,
timestamp date,
remarks varchar2(4000),
operation varchar2(30),
options varchar2(255),
object_node varchar2(128),
object_owner varchar2(30),
object_name varchar2(30),
object_alias varchar2(65),
object_instance numeric,
object_type varchar2(30),
optimizer varchar2(255),
search_columns number,
id numeric,
parent_id numeric,
depth numeric,
position numeric,
cost numeric,
cardinality numeric,
bytes numeric,
other_tag varchar2(255),
partition_start varchar2(255),
partition_stop varchar2(255),
partition_id numeric,

cpu_cost numeric,

temp_space numeric,
access_predicates varchar2(4000),
filter_predicates varchar2(4000),
