1. 先看下构建好的关系图谱如下: 2. 构建节点,并且导入数据 create table ch_from_to_count(idint primary key auto_increment...,substring_index(substring_index(t.toWho,';', b.help_topic_id+1), ';', -1) toWho ,caseId,countNum
遇到 图中需要将按uid分组count出每一个word_id个数的情况,需要用到substring_index函数 例子代码如下: SELECT COUNT(c.wid) as wcount, c.uid FROM ( SELECT a.uid AS uid, substring_index( substring_index( a.word_id, ',', b.help_topic_id + 1... 查看原文 mysql把一字段拆分为多行 一:...
