# Summary of tests:
|

#
|
||||
# speed4-join1: Join three tables using IPK index.
|

# speed4-join2: Join three tables using an index.

# speed4-join3: Join two tables without an index.
|
||||
#
|
||||
# speed4-view1: Querying a view.
|
||||
# speed4-table1: Same queries as in speed4-view1, but run directly against
|
||||
# the tables for comparison purposes.
|
||||
#
|
||||
# speed4-subselect1: A SELECT statement that uses many sub-queries..
|
||||
#
|
||||
# speed4-trigger1: An INSERT statement that fires a trigger.
|
||||
# speed4-trigger2: An UPDATE statement that fires a trigger.
|
||||
# speed4-trigger3: A DELETE statement that fires a trigger.
|
||||
# speed4-notrigger1: Same operation as trigger1, but without the trigger.
