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(RP)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。
Secondly, we construct the energy management system from the aspects of energy consumption statistic, equipment runtime statistic, parameter statistic and fault alarm. 随后对主教楼的能源管理系统进行建设,从耗能统计、设备运行统计、参数统计、故障报警等方面进行。
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。
In some cases, the access path does not perform well at runtime if the statement contains host variables, parameter markers, or special registers. 某些情况下,如果语句包含主机变量、参数标记或特殊寄存器那么访问路径在运行时的性能不会很好。
Try out the examples in this article to experience how you can improve runtime performance for queries that contain host variables or parameter markers by using the REOPT option. 通过尝试本文所给出的示例,您就能够体验到如何使用REOPT选项来提高那些包含主机变量或参数标记的查询的运行时性能。
