This no longer works if you use arbitrary tables and fields to specify the from clause or the result clause dynamically, though, because the result set types cannot be determined at programming time. 但是,如果使用任意数量的表和字段动态地指定from子句或result子句,就不能这样了,因为在编程时无法确定结果集类型。
For all rows produced by the start with clause LEVEL is set to1. 对于通过startwith子句生成的所有行,LEVEL被设置为1。
XMLQUERY is often used in the SELECT clause of an SQL query to extract or construct XML values based on the XML document in a given row of the result set. 在SQL查询的SELECT子句中,常常使用XMLQUERY根据结果集的给定行中的XML文档提取或构造XML值。
Usage: This parameter controls the decision on whether or not to apply a NON EMPTY clause on member requests when the number of tuples exceeds the set threshold. 用法:当元组数超过设定的阈值时,该参数控制是否对成员请求应用NONEMPTY子句的决策。
This is due to the semantics of SQL: without a WHERE clause, SQL queries do not filter out any rows from the table in the returned result set. 这是由于SQL的语义导致的:没有了WHERE子句,SQL查询就不会在返回的结果集中过滤掉表中的任何行。
Return: Using a return clause lets you operate on a node set, but then return ( in results) something other than that node set. return:使用return子句允许您操作操作节点集,随后返回除该节点集以外的结果。
As soon as a cycle is detected the appropriate flag defined in the CYCLE clause is set and the recursive query process for the branch is stopped. 一旦检测到循环,就会设置CYCLE子句中已定义好的适当标记,并停止分支的递归查询过程。

When you perform RUNSTATS with the WITH DISTRIBUTION clause, a set of frequency and quantile statistics is chosen, depending on the options given in the RUNSTATS command. 在执行包含WITHDISTRIBUTION子句的RUNSTATS时,会根据RUNSTATS命令中给定的选项选择一组频率(frequency)和分位数(quantile)的统计信息。
If you add an ORDER BY clause, to order by the extracted city value, the result set still remains the same: PARIS, paris, and Paris are treated as the same value. 如果通过添加ORDERBY子句按提取的city值排序,那么结果集仍然是相同的:PARIS、paris和Paris被当作相同的值。
As with any database UPDATE query, you must pass the YQL query a list of fields to be updated, together with their new values, and a WHERE clause that restricts the update to a set of records. 与任何数据库UPDATE查询一样,您必须向YQL查询传递要更新的字段列表,以及其新值和将更新限制为一组记录的一个WHERE子句。
If you use XML predicates in the XMLQUERY function in the select clause of an SQL statement, these predicates do not eliminate any rows from the result set and therefore cannot use an index. 如果在SQL语句的select子句的XMLQUERY函数中使用XML谓词,则这些谓词不会从结果集中排除任何行,因此不能使用索引。
Isolation level is set at the session level using SET ISOLATION, set at the SQL statement level using the WITH clause or set at the database level using a Database Configuration parameter. 使用SETISOLATION在会话级、使用WITH子句在SQL语句级或使用数据库配置参数在数据库级设置隔离级别。
The pseudo column LEVEL can be used in the ORDER BY clause to return the result set in search breadth first sequence. 可在ORDERBY子句中使用伪列LEVEL按照搜索宽度优先顺序返回结果集。
First, include in the index all the columns in the WHERE clause, so that index screening can be used to reject unqualified rows from the result set. 首先,在索引中包括WHERE子句中的所有列,这样,就可以使用索引形成的屏蔽来拒绝结果集中不合格的行。
Nonrestrictive phrase and clause are set off by commas. 非限制性短语或从句前后用逗号分隔。
Only one termination clause can be specified, and it follows the set clauses. 只能指定一条终止子句,而且该子句应跟在set子句后面。
Deciding satisfiability of clause set is one of the active research topics in the automated reasoning field. 子句集的可满足性判定是自动证明领域的热点之一。
The clause should be set off by a comma. 这个从句应该用逗号隔开。
But that clause dated from the 1940s Bretton Woods system of fixed global exchange rates, which the IMF was set up to administer. 但上述条款源自上世纪40年代布雷顿森林体系(brettonwoods)下的全球固定汇率制度当时成立了国际货币基金组织对此进行管理。
When the waitfor clause is specified, the statement waits for the timeout specified, or until a result set is available. 指定waitfor子句后,该语句将等待指定的超时时间,或等到结果集可用为止。
And then the improved notions to carry out engineering construction compulsory clause are set forth. 最后,对贯彻工程建设标准强制性条文提出改进意见。
The matrix representation of base clause set is presented and the method of simplification for matrix is discussed according to single literal rule and pure rule. 给出了子旬集的矩阵表示形式,根据单文字规则与纯文字规则,讨论了矩阵的化简策略,并定义了子句集矩阵的初等变换,研究了变换的性质。
Personals only acquire the right of laying down the primary rules for themselves from the legislators according to the clause of autonomy of private law in order to become rules, private rules need to stand the test of various qualifications set by legislators. 私人依据私法自治条款只是从立法者那里获得了为自己制定主要规则的权限;私人规则通往法律规则需要经受立法者设定的种种资格考验。
