当在会话中第一次引用时，全局变量将进行实例化来获得其默认值。
A global variable is instantiated to its default value when it is first referenced in the session.
如果在没有使用模式名情况下引用全局变量，则使用SQL路径协助解析名称。
When a global variable is referenced without the schema name, the SQL path is used to assist in the name resolution.
在第一次引用时，默认表达式将为全局变量计算一个值。
The default expression calculates a value to assign to the global variable the first time it is referenced.
它还会创建一个引用SPE程序的全局变量，这样ppe就能够将程序加载到SPE中并根据需要来运行程序了。
It also creates a global variable that refers to the SPE program so that the PPE can load the program into the SPEs and run the program as needed.
您应当十分熟悉用于填充带有 Flex应用程序引用的 flexApp全局变量的代码。
You should be familiar with the code used to populate the global flexApp variable with a reference to the Flex application.
请注意，如果函数、方法、触发器或视图中引用了某个全局变量，则不能删除该变量。
Please note that the global variable cannot be dropped if it is referenced in a function, method, trigger or view.
然后表达式中对变量的引用可以静态绑定到本地堆栈框架或一列全局变量的特定槽上。
References to variables within an expression can then be statically bound to a particular slot in either the local stack frame or the list of global variables.
当在函数或其它地方引用一个全局变量时，脚本引擎需要搜索整个全局命名空间。
Also when a global variable is referenced inside a function or another scope, the script engine has to search through the whole scope to find it.
如果DMLsql语句、触发器、视图或例程内引用了一个全局变量，将为语句或对象记录关于完全限定全局变量名的依赖关系。
When a global variable is referenced within a DML SQL statement or within a trigger, view or routine, a dependency on the fully-qualified global variable name is recorded for the statement or object.
READ权限用于引用全局变量，而WRITE权限用于修改全局变量的值。
The READ privilege is required to reference a global variable and the WRITE privilege is required to modify the value of a global variable.
如果在第一次引用全局变量没有为全局变量指定其他值，那么使用DEFAULT‘Printer 001’表示它的默认值。
Default 'Printer001' is the default value this global variable gets the first time it is referenced if no other value is assigned to it.
历史应用程序(即很过时的遗留代码)有时会直接引用这些全局变量，但会在编译过程中产生错误，因为它们的声明并不一致。
Historical applications (that is, horribly outdated legacy code) sometimes refer to these directly, but produce errors during compilation because they're declared inconsistently.
这是类是引用计数的，利用了我写的许多全局变量。
The class is ref counted, and makes use of many globals that I wrote myself.
保存引用一个全局变量在函数里面是一个问题，因为一个函数变量在函数看不见但是一个局域变量包含一个引用全局。
Storing references to global variables inside a function is a problem, as a global var inside a function seems to be nothing but a local var containing a reference to the global.
