执行顺序为:首先执行try语句块中的代码,如果抛出异常,接着执行catch语句块中代码,如果没有异常,catch语句块中代码将会被忽略,但不管是否有异常,最后最会执行finally子句。try后面必须接着一个catch或者finally,也就是说JavaScript中的try-catch可以有3中组合形式。即try-catch、try-finally、try-catch-finally三种形式。

为Transact-SQL 实现与 C# 和 Visual C++ 语言中的异常处理类似的错误处理。 一组 Transact-SQL 语句可以包含在块TRY中。 如果块中TRY发生错误,控件通常传递给包含在块中的另一CATCH组语句。 Transact-SQL 语法约定 语法 syntaxsql BEGINTRY{sql_statement|statement_block}ENDTRYBEGINCATCH[ {sql_statement|statemen...
在Jenkins声明性语法中,可以使用try-catch块来捕获和处理异常。try-catch块用于包裹可能会抛出异常的代码,并在异常发生时执行相应的处理逻辑。 以下是在Jenkins声明性语法中添加try-catch块的示例: 代码语言:txt 复制 pipeline { agent any stages { stage('Build') { steps { script { try { // 可能...
