bound variable

基本解释

Data from the bound variable is retrieved only during the execution of the SQL statement.
只有在 SQL 语句的执行期间才会检索绑定的标量。
The ResultSet allows you to iterate over each QuerySolution returned by the query, providing access to each bound variable's value.
ResultSet 支持在查询返回的每个 QuerySolution 上进行迭代，这提供了对每个绑定变量值的访问。
Note in the evaluation, if the pattern is a bound variable, or the element of the pattern is a bound variable, then the result of the pattern match becomes a comparison.
注意，如果模式是绑定的变量，或者模式的元素是绑定的变量，那么模式匹配的结果就会变成比较。

Just to remind you what it does, we bound x to some value, we set up an initial variable called ANS or answer, answer and then we run through a little loop.
记住你要做些什么，我们给x赋一个值,我们建立一个初始变量，命名为ANS或者。

这显示了我们想要做的另一件事,那就是我在这段代码中设置了一个,名为Solution，Found的变量,初始值设为。
