Mysql儲存過程中字串分割

今在專案中碰到了要把字串分割，記錄下來，以後可能還用的到

首先想上我的儲存過程**

delimiter $$

use `bplate`$$
drop procedure if exists `lp_plate_insertplateinfo`$$
create definer=`root`@`localhost` procedure `lp_plate_insertplateinfo`(
plate_user int,
plate_title varchar(60) ,
plate_type int,
plate_img varchar(500),
plate_content mediumtext,
plate_sku_name varchar(60),
plate_sku_price varchar(60)
)begin
declare i int default 0; 
set @sql1=concat("insert into bp_plate(`plate_user`,`plate_title`,`plate_type`,`plate_img`,`plate_sales`,`plate_content`,`plate_level`,`plate_time`,`plate_state`) value(",plate_user,",'",plate_title,"',",plate_type,",'",plate_img,"',",0,",'",plate_content,"',0,now(),1)"); 
prepare sql1 from @sql1;
execute sql1; 
set @plate_id='';
select last_insert_id() into @plate_id from bp_plate limit 0,1; 
set @arraylength=1+(length(plate_sku_name) - length(replace(plate_sku_name,',',''))); 
while i<@arraylength
doset i=i+1;
set @result = reverse(substring_index(reverse(substring_index(plate_sku_name,',',i)),',',1)); 
set @resultprice = reverse(substring_index(reverse(substring_index(plate_sku_price,',',i)),',',1));
insert into bp_plate_sku(`plate_id`,`sku_name`,`sku_price`,`sku_time`,`sku_state`) value(@plate_id,@result,@resultprice,now(),1);
end while; 
end$$
delimiter ;

這是我整個儲存過程，分割的是傳進來的

plate_sku_name varchar(60),

plate_sku_price varchar(60)

然後只要分割方法在於

set @arraylength=1+(length(plate_sku_name) - length(replace(plate_sku_name,',','')));		

while i<@arraylength
doset i=i+1;
set @result = reverse(substring_index(reverse(substring_index(plate_sku_name,',',i)),',',1)); 
set @resultprice = reverse(substring_index(reverse(substring_index(plate_sku_price,',',i)),',',1));
insert into bp_plate_sku(`plate_id`,`sku_name`,`sku_price`,`sku_time`,`sku_state`) value(@plate_id,@result,@resultprice,now(),1);
end while;

之後便是乙個while迴圈

中間用

reverse(substring_index(reverse(substring_index(plate_sku_name,',',i)),',',1));

裡面的『，』是根據要分割的字元，plate_sku_name是要分割的字串，變數i要從1開始

之後便能分割了
