The expression language includes a cast operator that supports casting between string, numeric, date, and binary data types
表達式語言包含支持在字元串、數值、日期和二進制大型對象塊( blob )數據類型之間進行轉換的轉換運算符。You must type default, including the single quotes, to specify the literal string value " default. " if you type the word default without any quotes, it most likely will evaluate to an empty string when this is evaluated as an xpath expression
為了指定文字字串值" default " ,必須輸入default ,單引號也要一起輸入。如果只是輸入default這個詞,而沒有帶單引號,那麼在xpath表達式中它將被當作空字串來處理。In addition, you can combine multiple expressions with static text to construct a dynamic attribute value through string concatenation, as highlighted in listing 4
此外,您可以將多個表達式與靜態文本組合在一起以通過字元串並置來構造動態屬性值,如清單4所示。For example, a data column with a string value cannot be converted to an integer, or an expression tries to divide by zero
例如,值為字元串的數據列不能轉換為整數,或嘗試除以零的表達式。Both are used to separate the responsibility for rendering pages from the model and controller. both accept objects passed into them as an input argument, both allow inserting string values within code " expressions ", and allow direct use of java code to perform loops, declare variable, or perform logical flows " scriptlets ". both are good ways of representing the structure of a generated object web page, java class, or file while supporting customization of the details
Jet與jsp非常類似:二者使用相同的語法,實際上在後臺都被編譯成java程序;二者都用來將呈現頁面與模型和控制器分離開來;二者都可以接受輸入的對象作為參數,都可以在代碼中插入字元串值(表達式) ,可以直接使用java代碼執行循環、聲明變量或執行邏輯流程式控制制(腳本) ;二者都可以很好地表示所生成對象的結構, ( web頁面、 java類或文件) ,而且可以支持用戶的詳細定製。In particular, the curly brackets instruct db2 to evaluate the enclosed expression in the case, " e " rather than treat it as a literal string
具體來說,花括號( { } )指示db2計算被括起來的表達式(在這里是" $ e " )的值,而不是將其視作一個文字字元串。Returns a string expression representing a date time value
返回表示日期時間值的字元串表達式。Expression numeric expressions or string expressions to print
要列印的數值表達式或字元串表達式。Any numeric or string expression
任何數值或字元串表達式。A regular expression that matches a string literal and has a match value of the literal itself
匹配字元串文本並且包含文本本身的匹配值的正則表達式。A string representing the expression s prefix value
一個字元串,表示表達式的前綴值。A string is true if and only if its length is non - zero
一個字元串當且僅當它的長度不為0是,表達式的值為真。The expression evaluator supports function calls with by value arguments but does not support function calls with by reference arguments, objects, arrays, functions, and strings
該表達式計算器支持具有「通過值傳遞」的參數的函數調用,但不支持具有「通過引用傳遞」的參數、對象、數組、函數和字元串的函數調用。If the intent is to specify a string literal, such as a fixed string value such as default, then the correct way to express this in xpath is to enclose the string in single quotes
如果是要指定一個字串文字,例如一個固定的字串值default ,那麼在xpath中正確的表達方式是用單引號將該字串括起來。Describes the numeric, string, and boolean literals that the expression evaluator supports
說明表達式計算器支持的數值、字元串和布爾文字。分享友人
