For example, a single declared pureQuery bean parameter can potentially provide runtime values for several SQL statement parameter markers. 例如,一个声明的pureQuerybean参数可以为一些SQL语句参数占位符提供运行时值。
Although db2-fn: sqlquery allows embedding an SQL statement inside XQuery, currently it is not possible to have regular SQL-style parameter markers in the embedded SQL statement. 尽管db2-fn:sqlquery允许在XQuery内嵌入SQL语句,但目前还不能在嵌入式SQL语句中使用参数标记。

Use parameter markers to prepare an SQL statement once, and then reuse it many times. 只需在SQL语句中使用一次参数标记,然后就可以多次重用。
Validate data: Statement hooks let you validate parameter data before statement execution, providing the opportunity to do constraint check and data validation at the application level. 验证数据:通过语句钩子可以在执行语句之前验证参数数据,从而为应用程序级的约束检查和数据验证提供机会。
There can be, but there is not necessarily, a one-to-one mapping of parameter markers in the SQL statement to declared parameters in the annotated method. SQL语句中的参数占位符与带注释的方法中声明的参数之间可能存在一对一的映射,但是也不一定如此。
The value is specified as the id parameter to the argument and is included in the SQL statement as# { id}, just as it is in the XML configuration. 这个值被指定为实参的id参数并被作为{id}包括在这个SQL语句内,正如其在XML配置中那样。
The parameter types in the annotated method declaration determine how pureQuery obtains SQL statement parameter values at runtime. 带注释的方法声明中的参数类型决定pureQuery如何在运行时获得SQL语句参数值。
Use the LOCKSIZE parameter of the ALTER TABLE statement to control how locking is done for a specific table on a permanent basis. 使用altERTABLE语句的LOCKSIZE参数控制如何在持久基础上对某个特定表进行锁定。
The SQL Maps framework will create a PreparedStatement instance, set any parameters using the provided parameter object, execute the statement, and build a result object from the ResultSet. SQLMaps框架将创建一个PreparedStatement实例,使用所提供的参数对象设置所有参数、执行语句以及从ResultSet中构建一个结果对象。
To call your function from a Java program prepared statement, you will need to use a CAST for each input parameter in your prepared statement like this 如果要从Java程序的预备语句中调用函数,则需要在预备语句中对每个输入参数使用一个CAST,方法如下
As we've discussed in this article, the DB2 optimizer may choose a sub-optimal access plan when there are host variables or parameter markers in the SQL statement. 正如我们在本文讨论的,如果SQL语句中存在主机变量或参数标记,那么DB2优化器可能会选择一个次优化的存取计划。
The sayHello() function takes one parameter, which it outputs to the console in the following println() statement. sayHello()函数只有一个参数,它会使用println()语句将这个参数输出到控制台。
Once an application variable is bound to a parameter marker, the association remains until it is overridden or until the corresponding statement handle is freed. 一旦应用程序变量被绑定到某个参数标记,这种关联就会一直保持下去,直到相应的语句句柄被释放。
While this article does not discuss application development topics in detail, it includes a simple Java example that uses a parameter marker within an SQL/ XML statement to restrict output to information about customers who live in a given zip code. 虽然本文不详细讨论应用开发话题,但还是提供了一个简单的Java例子,这个例子在一条SQL/XML语句中使用一个参数标记位将输出限制为居住在给定地区的客户的信息。
PureQuery follows the rules for parameter marker syntax to determine how SQL statement parameters are mapped from the declared parameters in the annotated method's parameter list. pureQuery遵从参数占位符语法规则来决定如何从带注释的方法的参数列表中声明的参数映射SQL语句参数。
For batch updates, a collection parameter is used vertically to execute an SQL statement more than once, with different parameter values each time. 对于批量更新,需要使用一个集合参数多次执行一条SQL语句,每次执行时使用不同的参数值。
The php code in the action extracts the customerName parameter from the POST and creates an sql statement for the insert. 动作中的php代码从POST提取customerName参数并为插入创建一个sql语句。
Instead of having to write separate method calls to bind each input parameter and retrieve each select list item, you can write one SQL statement that uses Java host variables. 现在无需编写不同的方法调用来绑定每个输入参数和获取每个选择列表项,而只需编写一条使用Java宿主变量的SQL语句。
The declared parameter type for an annotated method can make a significant difference in how the SQL statement is executed. 带注释方法的声明的参数类型可以在很大程度上影响SQL语句的执行。
For example, processing may vary depending on the name of the interface method calling the Hook method, the runtime parameter values provided to that method, or the SQL statement type which the method executes. 例如,取决于调用Hook方法的接口方法的名称、提供给那个方法的运行时参数值或者该方法执行的SQL语句类型的不同,处理也会有所不同。
Alternatively, you can pass the MIML file from an application through a parameter marker into the insert statement. 或者,也可以通过一个参数占位符将MIML文件传递给insert语句。
The parameter object will be used to set input values in an UPDATE statement, or WHERE clause values in a query ( etc.). 这个参数对象将用于设置UPDATE语句中的输入值,或者用于设置某一查询中的WHERE子句的值(等等)。
The key ( or keys) are used to replace the parameter marker ( or markers) which were defined as part of the SQL statement string created in the RPG HANDLE_OPEN sub-procedure. 这个键(或多个键)用于替代这个参数标记(或多个标记),参数标记被定义为在RPGHANDLEOPEN子过程中创建的SQL语句字符串的一部分。
For each such parameter in the SQL statement, there should be a corresponding 对于SQL语句中每个这样的参数来说,应有相应的
A dollar sign ($) followed by digits is used to represent a positional parameter in the body of a function definition or a prepared statement. 美元符号($)后面跟着数字用于在一个函数体定义或者准备好的语句中表示参数的位置。
A constitutive model of 3D contact with friction is established with the use of penalty parameter and an incremental statement of problem is carried out. 借助罚因子建立了三维摩擦接触边界的本构模型,给出了三维摩擦接触问题的增量描述,推导了接触问题的互补虚功方程。
This antetype can handle the parameter, statement, and audit data of the security devices by network, affording facilities for the security devices manager and providing the foundation of the heterogeneous network's whole safeguard. 该原型系统能够对安全设备参数、安全设备工作状态、安全设备管理审计等重要数据,实施统一处理和网络化管理,方便安全设备管理员的管理工作,为异构通信网络的整体安全保障提供基础。
