mysql存储过程实现split mysql drop procedure if exists procedure_split;create procedure `procedure_split`( inputstring varchar(1000), delim char(1))begin declare strlen int default length(inputstring); declare last_index int default 0; declare cur_index int default 1; declare cur_char varchar(200); declare len int; drop temporary table if exists splittable; create temporary table splittable( value varchar(20) ) ; while(cur_index<=strlen) do begin if substring(inputstring from cur_index for 1)=delim or cur_index=strlen then set len=cur_index-last_index-1; if cur_index=strlen then set len=len+1; end if; insert into splittable(`value`)values(substring(inputstring from (last_index+1) for len)); set last_index=cur_index; end if; set cur_index=cur_index+1; end; end while;end ;
call procedure_split('中国,开源,社区',',');select * from splittable;
