-- @num_samples is the number of times to capture waitstats, default is 10 times
-- default delay interval is 1 minute
-- delaynum is the delay interval - can be minutes or seconds
-- delaytype specifies whether the delay interval is minutes or seconds
-- create waitstats table if it doesn't exist, otherwise truncate
-- Revision: 4/19/05
--- (1) added object owner qualifier
--- (2) optional parameters to truncate history and clear waitstats
