In many basic table-based queries, to meet one condition, you often need to join another table. In this case, using EXISTS (or not exists) usually improves the query efficiency. IN a subquery, the not in Clause executes an internal sorting and merging. IN either case, not in is the most inefficient (because it executes a full table traversal for the table IN the subquery ). To avoid using not in, we can rewrite it into an Outer join (Outer Joins) or not exists.For exampleI want to query the redu
In many base table based queries, a join to another table is often required to satisfy one condition. In this case, using EXISTS (or not EXISTS) usually increases the efficiency of the query. In a subquery, the NOT IN clause performs an internal sort and merge. In either case, not in is the least efficient (because it performs a full table traversal of the table in the subquery). In order to avoid using not in, we can rewrite it as an outer join (Outer joins) or not EXISTS.
