However, it will not exceed 120% of the physical memory size minus the total SGA size.
More DetailsDeveloped by Karlotta Thorhallsdóttir. Impact and probability are the two main components of Risk analysis.Looking at impact versus probability is common in order to categorize and prioritize risks as some risks may have a severe impact on projects objectives but only happen on rare occasions, while other have a moderate impact but occur more frequently.
More DetailsThe aggregate impact value is the proportion of the sample that passes a 2.36 mm sieve after the hammer impacts. European Standards will not contain the 10 per cent fines test or the aggregate impact value test (although a different impact test, the German Schlagversuch test, has been included).
More Details· See: drop table abc create table abc ( a int ) go insert into abc values (1) insert into abc values (null) insert into abc values (2) select max (a) from abc (1 row (s) affected) Warning: Null value is eliminated by an aggregate or other SET operation. Now this can be rectifed by doing: SELECT max (isNull (a,0)) FROM abc.
