If you get a lot of “path not found” messages when you use whereis or which, you might want to makeadditions to the list of directories in the path statement in .cshrc in your home directory.
(如果使用whereis或which时得到大量的"pathnot fount"信息提示，你可能需要在你的home目录中的.cshrc文件中的路径声明里添加相应目录的列表)。

For a given SQL statement, there are often multiple access path choices, and the different access paths usually have different performance characteristics.
对于一个给定的sql语句，往往有多个访问路径选择，而不同的访问路径具有不同的性能特点。
For simplicity, this article refers to a particular way of satisfying an SQL statement as the access path.
为简单起见，本文引用了一种满足sql语句的流行方法作为访问路径。
Answering these questions generates the query's access path; your tuning aim is to get a better path that will reduce statement execution time.
回答这些问题就会确定查询的访问路径；调优的目标是找到更好的路径，减少语句的执行时间。
Access plan describes the access path that the DB2 optimizer has chosen for accessing data for an SQL statement.
访问计划描述访问路径，这些路径是DB 2优化器为sql语句访问数据而选择的。
The SQL statement itself also impacts the access path selection.
sql语句本身也会影响访问路径选择。
The key performance benefit of parameterized queries is that the optimizer can formulate an access path that can be reused over repeated executions of the statement.
参数化查询的主要性能好处是优化器可以制定在重复执行语句时能够再使用的存取路径。
It analyzes SQL statements and determines the most efficient access path available for satisfying each statement (see Figure 1).
它分析sql语句并确定可以满足每条语句的最有效的存取路径(请参阅图1)。
The SQL compiler USES them to transform a statement into a more optimized form, thus improving the access path to the required data.
SQL编译器使用信息约束将语句转化成更优的形式，从而改善对所需数据的访问路径。
The SQL compiler USES query optimization to select the best performing access path for any given SQL statement (within a reasonable amount of time, of course).
SQL编译器使用查询优化来为任何给定的sql语句选择表现最好的访问路径(当然，这要在合理的时间内)。
If the SQL statement is badly coded, it is difficult for the optimizer to transform the query, leaving fewer options available for choosing an optimal access path.
如果sql语句设计得很糟，优化器就很难转换查询，在选择最佳访问路径时的选择就很少。

The SQL statement in Listing 6 creates the access path graph shown in Figure 6.
清单6中的sql语句创建如图6所示的访问路径图。
In this example, I add my local mylib directory to the include path so I can require PHP files from that directory without adding the path to the require statement.
在本例中，我将我的本地mylib目录添加到了include路径中，所以能够从该目录中requirePHP文件，而不需要将该路径添加到require语句中。
You can also create a link to the interfaces file or use the IFILE server option in the create server statement to specify the full path to the file.
您还可以创建到interfaces文件的链接，或者在CREATEserver语句中使用IFILE服务器选项指定到该文件的全路径。
Then, a second case statement is used to identify the path of the request.
随后，使用第二条case语句来识别请求的路径。
The original message (InputRoot) is available each time after control is returned to the statement following the Propagate node when the individual path is completed.
每次在完成了单个路径且控制返回给Propagate节点后的语句时，原始消息(InputRoot)就可用。
At a given if-then-else statement, the if part is the path that was executed.
对于给定的if - then - else语句，if部分就是被执行的路径。
