Webb5 jan. 2016 · If you are going to this you should at least use the OPTION ( HASH JOIN ) syntax instead. Using the LEFT HASH JOIN syntax implicitly enforces the join order. This is not desirable for hash joins where normally you would expect the smaller of the two tables being joined to be the build input, the top-most table in the execution plan. WebbThese hints allow you to instruct the optimizer to use a hash join, a sort-merge join, or nested loops, respectively. Hash joins support input swapping, which we have discussed when we talked about left-deep and right-deep join trees . This can be accomplished with SWAP_JOIN_INPUTS or prohibited with NO_SWAP_JOIN_INPUTS.
