• The article should only have one parameterized filter or join filter.

    项目只有一个参数化筛选联接筛选器。

    youdao

  • Each join reduces the size of the fact table by one-tenth due to selectivity of the table filter on each dimension table.

    由于每个维度过滤选择度每次连接都会减少事实大小的十分之一。

    youdao

  • This is the same join predicate applied at FILTER(10).

    应用FILTER(10) 的连接断言相同

    youdao

  • Often the join order of a query will greatly determine the query execution performance, since it is more efficient to filter rows as early as possible.

    通常查询连接顺序很大程度上决定查询执行性能因为早地过滤效率越高。

    youdao

  • The performance improvement depends on the selectivity of the filter on the dimension table from which the join keys are pushed down.

    性能提高取决于连接时所在维度过滤选择度。

    youdao

  • When hash tables are built, join keys are pushed down and used to filter the rows of the fact table, and performance improves dramatically.

    构建列表连接用于过滤事实性能也显著提高

    youdao

  • In a star join plan, the database server pushes down keys from a dimension table to filter the fact table at the same time as it builds the hash table on the dimension table.

    星型连接计划中,数据库服务器维度构建列表同时维度表中下过滤事实表。

    youdao

  • Use UPDATE STATISTICS HIGH if queries have a multi-column indexed defined on join columns or filter columns.

    如果查询属于多索引连接过滤列,则使用UPDATESTATISTICSHIGH

    youdao

  • The time_id join keys that meet the filter requirements on the Time dimension table are hashed to create a bit vector that filters rows of the Orders table from the skip scan above.

    Time维度满足过滤条件 time_id连接散列创建一个向量,用于过滤以上跳跃式扫描Orders

    youdao

  • Use UPDATE STATISTICS MEDIUM DISTRIBUTIONS ONLY if queries have non-indexed join columns or filter columns.

    查询非索引连接过滤列时,才使用UPDATESTATISTICSMEDIUMDISTRIBUTIONS

    youdao

  • The location_id join keys that meet the filter requirements on the Location dimension table are pushed down to the index on the Orders table.

    Location维度满足过滤条件 location_id连接下推至Orders 表的索引

    youdao

  • Exclude rows by defining a filter on a table. You can extend the filter by defining a JOIN from a filtered table to another table.

    通过定义筛选可以排除某些,还可以通过定义筛选其它表的联接来扩展筛选。

    youdao

  • We could then apply a tree manipulation to move the Filter node underneath the Join node toward the related Table node.

    随后我们可以应用一项操作Join节点下方Filter节点朝着相关Table节点的方向移动。

    youdao

  • The join condition is the on clause filter specified in the merge statement.

    merge语句的on子句指定联接条件

    youdao

  • The join condition is the on clause filter specified in the merge statement.

    merge语句的on子句指定联接条件
