Scala中三个引号应用 双引号 1.换行需要加/n ,比如: val s = "select * from user \n where user_id >100" println(s) 控制台输出结果: select * from user where user_id >100 三引号 1:中间字符串可以直接回车换行 val s ="""select * from user where user_id >100 and age <18 """ println(s) 控制台输出结果: select * from user where user_id >100 and age <18 2:保留代码块原意,中间可以有双引号 val s ="""select * from user where user_id >100 and name="dudu" """ println(s) 控制台输出结果: select * from user where user_id >100 and name=“dudu” 3:格式化 在idea中输入三个双引号,回车,行头会出现|,回车一次,会出现一个|,结尾是.stripMargin val s = """select * |from user |where user_name="dudu" |and age = 18 """.stripMargin
