|
| -#
|
| -# 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.
