SQLyog执行多个语句需加分号

运行下面两行查询：

UPDATE alicallbackinfo SET out_trade_no='100220515453453463464'  WHERE backinfoid=1550085

SELECT out_trade_no FROM alicallbackinfo WHERE backinfoid=1550085

错误信息：

查询：update alicallbackinfo set out_trade_no='100220515453453463464' where backinfoid=1550085 SELECT out_trade_no FROM alicallbackinf...

错误代码： 1064

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SELECT out_trade_no FROM alicallbackinfo WHERE backinfoid=1550085' at line 3

看样子是把两句连接成了一个SQL语句来理解了，所以报语法错误。于是我试着在每句后面加了分号，成功解决了这个问题。

UPDATE alicallbackinfo SET out_trade_no='100220515453453463464'  WHERE backinfoid=1550085;

SELECT out_trade_no FROM alicallbackinfo WHERE backinfoid=1550085;
