1.把字符串转化为数组 ToArray 函数:split() 功能:使用一个指定的分隔符把一个字符串分割存储到数组 1 (function(){ 2 //把字符串以','来分割成数组形式 3 var oData='1,2,3,4,5,6' 4 var oSub=oData.split(','); 5 console.log(oSub) 6 //[1,2,3,4,5,6] 7 })() 1. 2. 3. 4...
A string is a collection of characters joined together. When these characters are divided and stored in a variable, that variable becomes an array for these characters. The method we use to split a string into an array is by using the SPLIT function in VBA, which splits the string into a...
In VBA, we already know and use different types of data types. In this article, we are going to see VBA Split String into Array. This means we will using the SPLIT function in VBA to split the String or text line into an Array or put the string into different lines by splitting the...

如此实现,但是string_to_array需要子查询,当与其他自动group by一起查询的时候就显得及其不方便,因此可使用方法二。 方法二:split_part selectsplit_part('休闲,娱乐,运动,玩耍',',',1);---休闲--(1 row)selectsplit_part('abc~@~def~@~ghi','~@~',2)---def--(1 row) END 2018-08-01 17:03:...

hive array 转换数据类型 hive中string转array 目录 一.行转列 相关函数 concat concat_ws collect_set collect_list 需求 需求分析 数据准备 写SQL 二.列转行 相关函数 split explode lateral view 需求 需求分析 数据准备 写SQL 一.行转列 相关函数
第一种方法: string_to_array select string_to_array('休闲,娱乐,运动,玩耍', ','); string_to_array --- {休闲,娱乐,运动,玩耍} (1 row) select tag[1] from ( select string_to_array('休闲,娱乐,运动,玩耍', ',') as tag) a; tag --- 休闲 (1 row) 但是string_to_array 有个缺陷,...
在PostgreSQL中,split_part函数用于按指定字符分割字符串并获取指定位置的部分。例如:select split_part('aaa^bbb^ccc^dd','^',3);输出结果为:ccc。replace函数则用于在字符串中替换指定的字符或子串。例如:select replace('abcd,efg',',','*');输出结果为:abcd*efg。unnest函数配合数组使用,...
