mysql 存储过程字符分割

s_str varchar(2000), s_split varchar(2)

begin
/*split分割字符串并放入临时表*/
declare lenstr int ;
declare result varchar(248) default '';
declare i int DEFAULT 1;
set lenstr= length(s_str)-length(replace(s_str, s_split, ''))+1;
BEGIN
drop table if exists tx_strlist;
DROP TEMPORARY TABLE IF EXISTS tx_strlist;
create temporary table tx_strlist(col VARCHAR(488) not null);
while i<=lenstr DO
set result =reverse(substring_index( reverse(substring_index(s_str, s_split, i)), s_split, 1));

INSERT into tx_strlist(col) values(result);
set i=i+1;
end while;
