If there is not enough cache memory to hold all the rows that have a particular value of the join attributes, then, if possible, each Hash Join algorithm dynamically switches to an index-based nested loops strategy after first discarding the interim results to avoid exhausting the statement's memory consumption quota.
In a nutshell, the Hash Join algorithm builds an in-memory hash table of the smaller of its two inputs, and then reads the larger input and probes the in-memory hash table to find matches.
If the in-memory hash table constructed by the algorithm does not fit into available memory, the Hash Join algorithm splits the input into partitions (possibly recursively for very large inputs) and performs the join on each partition independently.
The Hash Join algorithm is disabled on Windows CE in low memory conditions.
ハッシュ・ジョイン・アルゴリズムはメモリ不足状態の Windows CE では無効になります。
The Recursive Left Outer Hash Join is a variant of the Hash Join algorithm used in certain recursive union queries.
再帰左外部ハッシュ・ジョインは、ハッシュ・ジョイン・アルゴリズムの変形の 1 つで、特定の再帰的な UNION クエリで使用されます。
Partial Objects in ORMs: loading a subset of properties The hash join algorithm aims for the weak spot of the nested loops join: the many B-tree traversals when executing the inner query.
If the Hash Join algorithm executes in an environment where there is not enough cache memory to hold all the rows that have a particular value of the join attributes, then it is not able to complete.
