Question

我想在测试表中获取该名称并将其拆分为＆＃34;至＆＃34;字和＆amp;在abc表中插入拆分的字符串。触发器被触发，但是当插入数据进入测试时它会生成＆＃34;＃1172 - 结果由多行组成＆＃34; phpMyAdmin中的错误。请帮我解决一下这个。

DROP TRIGGER IF EXISTS `split_after_insert`;
CREATE DEFINER=`root`@`localhost` 
TRIGGER `split_after_insert` AFTER INSERT ON `test` 
FOR EACH ROW 
BEGIN
     DECLARE vName varchar(50);

     -- Find name of person performing the INSERT into table

    SELECT SUBSTR(name,(POSITION("to" IN name)+4),20) FROM test INTO vName;

    -- Insert record into abc table

   INSERT INTO abc(a) VALUES (vName);

END

DROP TRIGGER IF EXISTS `j`;
CREATE DEFINER=`root`@`localhost` 
TRIGGER `j` AFTER INSERT ON `test` 
FOR EACH ROW 
BEGIN

   DECLARE vName varchar(100);
   DECLARE vtemp varchar(100);

   select new.name into vtemp;

   -- Find name of person performing the INSERT into table
   SELECT SUBSTR(vtemp,(POSITION("to" IN vtemp)+3),20)  INTO vName;

   -- Insert record into abc table
   INSERT INTO `abc`(`a`) VALUES (vName );

END
