Before the join begins, the database server first applies filters if there are any, and then sorts the rows for each table on the join column.
连接开始之前，如果有筛选器，那么数据库服务器首先会应用它们，然后对连接列上每个表中的行进行分类。
The join is performed by scanning the inner table of the hash join, CUSTOMERS, and generating a lookup table by hashing the join column values.
该连接的执行过程包括扫描散列连接中的内表CUSTOMERS，并通过散列连接列的值生成一个查找表。
On the other hand, if the first join column is an integer, the related join column must also be of an integer data type, but it can be a different size.
另一方面，如果第一个联结资料行为整数，则关联的联结资料行也必须为整数资料型别，但资料大小可有所不同。
IT then reads from the outer table BAD_CREDIT using the SHIP operator, hashing the join column values, and checking in the lookup table generated for the inner table.
然后，它使用SHIP操作符读外表BAD_CREDIT，散列连接列的值，并检查为内表生成的查找表。
If there is an index on the join column, the costs will be significantly less; otherwise the database server must perform table scans for all tables, both outer and inner tables.
如果连接列上有一个索引，那么其成本会相当低；否则，数据库服务器就必须对所有表(外部和内部表)执行表扫描。
Figure 8 shows that the left outer join operations are cascaded if a rule USES more than one reference column.
图8展示了如果规则使用了多个参考列，那么左外部连接就进行级联。
In a subsequent data flow operation, you'll use a join operator to ensure that full XML account records (contained in the INFO column) are fed into the target data warehouse table.
在随后的数据流操作中，您将使用一个连接操作符确保整个XML账户记录(包含在info列中)被填充到目标数据仓库表中。
The schema does not need to specify explicitly that a column is a primary or unique key to produce a star join plan.
模式不需要明确指定一列是主键或唯一键来产生星型连接计划。

对于客户类型来说，在JLT_T077D上使用其相应的支持数据来联接来自E2KNA1M 005表的列ktokd，使用KTOKD作为联接键。
When a join is executed that incorporates an index that is selective, any column in the dimension table can be used.
当连接执行时，合并选中的索引，此时维度表中的任何列都可使用。
As shown in the IXSCAN descriptor in Figure 8, the leading column of the index exploited by optimizer is PRODUCT_NUMBER, which does not provide the order required for merge scan join.
如图8的IXSCAN描述符所示，通过优化器利用的索引的领先列是PRODUCT _ NUMBER，其不为合并扫描联接提供所需的顺序。
The example USES the ID column as the join key.
示例使用id列作为连接键。
Using JoinRowSet lingo, our JOIN operation was performed using a match column of DEPTID.
在使用JoinRowSet lingo时，JOIN操作是通过匹配列deptid来执行的。
This can serve as a join key for the integer-based "id" column in the "clients" table.
这可以作为与“clients ”表中基于整数的列“id ”的一个连接键。
There is also a full outer join between these two sub queries based on a column called sc.
在基于名为sc 的列上还有两个子查询的完全外连接。
An inner join is essentially the intersection of two tables, where the tables are matched by comparing the values of a key column, such as itemNumber.
内连接实际上是两个表的交集，它通过比较关键列(比如itemnumber)的值来匹配表。
In this case, the first column of any index, simple or compound, is a candidate to satisfy the star join.
在这种情况下，任何索引的第一行，不管简单或复杂，都是满足星型联接的一个候选者。
Terry's column was to join him in two days.
泰瑞的纵队将于两天之后加入他。
The result set from FETCH (3) is ordered by the ID column and joined using a merge join with index I1 for T1 to get final result set.
FETCH(3)的结果集是根据ID字段排序的，并且使用T1的索引I1的合并联接而得到最终的结果集。
The last table in the join sequence, CUST_CUSTOMER, is also scanned through an index defined over the CUST_CODE column.
联接序列中的最后一个表是cust_customer表，其也是通过CUST _ code列上已定义的索引进行扫描。
If the join key is a composite key, each key column must be prefixed with the PRIOR operator.
如果联接键是一个复合键，那么必须使用PRIOR运算符为每个键所在的列加上前缀。
For a nullable joined column, is it better performance to do a outer join, or inner join to a "null" row?
一个空连接柱，它是更好的性能做了一个外连接，或内加入一个“空”行吗？
