bound variable

基本解釋

Data from the bound variable is retrieved only during the execution of the SQL statement.
衹有在 SQL 語(yǔ)句的執(zhí)行期間才會(huì)檢索綁定的標(biāo)量。
The ResultSet allows you to iterate over each QuerySolution returned by the query, providing access to each bound variable's value.
ResultSet 支持在查詢返廻的每個(gè) QuerySolution 上進(jìn)行疊代，這提供了對(duì)每個(gè)綁定變量值的訪問(wèn)。
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，如果模式是綁定的變量，或者模式的元素是綁定的變量，那麼模式匹配的結(jié)果就會(huì)變成比較。

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.
記住你要做些什麼，我們給x賦一個(gè)值,我們建立一個(gè)初始變量，命名爲(wèi)ANS或者。

And that shows you one other nice little thing we want to do, which is if I look in this code notice I set up a variable up here called false Solution Found, initially bound to false.
這顯示了我們想要做的另一件事,那就是我在這段代碼中設(shè)置了一個(gè),名爲(wèi)Solution，F(xiàn)ound的變量,初始值設(shè)爲(wèi)。
