Several basic blocks could be merged into a hyperblock in predicated execution so that instructions could be scheduled on a larger scope and more instruction level parallelism could be extracted.

Using this predicate, the container will execute the SQL statement in the sample below.
执行该查询将计算谓词以查找所有与模板实例匹配的实例。
Execution of this query evaluates the predicate to find all instances that match the template instance.
不管数据行是否被提交，以及根据语句的谓词它是否被排除，对于索引扫描和表访问都执行这样的锁定操作。
This locking was done for both index scans and table access whether or not the row of data was committed or whether it would have been excluded based on the statement's predicates.

The sections above described how you can model authorization rules, by defining what staff verb applies, and which input parameters it will receive to execute that rule at run time.
考虑在联邦服务器上，而不是在远程数据源上执行的选择谓词的影响。
Consider the effect of a selective predicate being evaluated at the federated server instead of at the remote data source.
执行谓词分析，看看能否尽量被选中。
Perform predicate analysis to see if the predicates are being as selective as possible.
同时，您还可以执行谓词分析，查找注释视图中是否有潜在问题，如图9所示。
Meanwhile, you can also do predicate analysis to find if there is any potential problem in the annotation view, as shown in Figure 9.
该过程将创建下列表、存储建议以及与查询执行过程中碰到的谓词有关的信息。
This procedure will create the following tables that store recommendations, and information about the predicates encountered during query execution.
由于该查询没有包含用来限制books或authors表的值谓词，因此DB 2必须在两个表上执行表扫描，以便读取所有authorID。
Since this query contains no value predicate to restrict either the books or the authors table, DB2 has to perform a table scan on either of the two tables to read all author IDs.
这个连接的执行计划的正确性取决于优化器对涉及到P_ RETAILPRICE的谓词将从PART的800,000行中选择多少行这一问题的估计。
The correct execution plan for this join depends on the optimizer's estimate of how many of PART's 800,000 rows will be selected by the predicate involving P_RETAILPRICE.
由于查询1表达了books表中的连接谓词，所以DB 2 9.1和9.5执行一个扫描authors的表，然后使用索引authoridx 1查找books表。
Since Query 1 expresses the join predicate on the books table, DB2 9.1 and 9.5 perform a table scan on authors and then use the index AUTHORIDX1 to probe into the books table.
如果您的目的是要实现真正的“between”谓词，则右侧的执行计划会更好一些，因为带有启动谓词的单个范围扫描仅传递匹配的行id。
If your intention is a real "between" predicate, then the execution plan on the right is much better, because a single range scan with a start-top predicate delivers the matching row IDs only.
在V 8中，谓词没有被下推到CF，为了计算谓词和执行聚合，需要将大约1百万个行移动到联邦服务器。
In V8, the predicate was not pushed down to CF, and nearly one million rows had to be moved to the federated server to evaluate the predicate and perform the aggregate.
基数估计是这样一种过程：在应用了谓词或执行了聚集之后，优化器使用统计信息确定部分查询结果的大小。
Cardinality estimation is a process by which the optimizer USES statistics to determine the size of partial query results after predicates are applied or aggregation is performed.
因此，只将它们编译（“准备”）一次，然后在每次执行时只传递谓词的字面值，这样做很有用。
Thus, it's useful to compile ("prepare") them just once and only pass predicate literal values for each execution.
原生查询为执行复杂查询提供了一种功能强大的方法，而且不需要学习新的查询语言或使用复杂对象结构对谓词建模。
Native queries provide a powerful way to execute complex queries without having to learn a new query language or resort to complicated object structures to model a predicate.
在部署期间，将把参数化的人员谓词转换为具体的人员查询(也称为员工查询)，这些人员查询特定于用来执行查询的人员存储库。
During deployment, the parameterized staff verbs are transformed into concrete staff queries (also known as people queries) that are specific to the staff repository used to perform the query.
为了删除文档，需要执行delete语句，并加上适当的where谓词。
To remove the document, issue a DELETE statement with an appropriate WHERE predicate.
参数化谓词是XSLT转换的输入，此转换将抽象的谓词映射到一组可由人员解析插件执行的人员查询。
The parameterized verb is the input for the XSL transformation, which maps the abstract verb into a set of staff queries that can be executed by a staff resolution plug-in.
使用哪个XSLT文件将人员谓词及其参数映射到可在运行时执行的具体人员查询。
What XSLT file is used to map the staff verb and its parameters to a concrete staff query that is executable at run time. The XSL transformation!

Proof through the state predicates can reflect the state of program execution.
根据状态谓词进行证明，能够反映出程序执行的状态。
Proof through the state predicates can reflect the state of program execution.
