STRING类型的分隔符,支持正则表达式语法。 trimTailEmpty: 可选参数,默认值为true,设置为false时保留末尾空字符串 (Hive兼容)。 返回值说明 返回ARRAY数组。数组中的元素为STRING类型。 使用示例 --返回["a"," b"," c"] select split("a, b, c", ","); --默认不返回空字符串 select split("a, b,...
原型:char *strtok(char *str, constchar *delim); strtok函数包含在头文件<string.h>中,对于字符数组可以采用这种方法处理。当然也可以将字符数组转换成字符串之后再使用法一。测试代码如下 #include <string.h>#include<stdio.h>intmain(){chars[] ="a,b*c,d";constchar*sep =",*"; //可按多个字符...
Excel split string by character function Let's suppose we have the following string separated by newlines in cell A2 : Cristine Alliguay 42 New York We will use the CHAR function in our previous commands to split these strings from our desired columns. Here are the commands to get the...
