Question

我一直在尝试修复过去30分钟内的SQL状态错误。我在这做错了什么？欢迎任何建议。

$statement=$conn->prepare("SELECT to.ipaddress as ipaddress, to.email as email, to.orderdate as orderdate, to.is_completed as is_completed, p.price as price from temporder to, products p WHERE to.productid = p.productid AND to.ipaddress=? AND to.orderdate=? ");
$statement->execute(array(
$_SERVER['REMOTE_ADDR'],
date('Y-m-d')
));
$statement->setFetchMode(PDO::FETCH_ASSOC);

完成错误

SQLSTATE [42000]：语法错误或访问冲突：1064 SQL语法中有错误;检查与您的MySQL服务器版本相对应的手册，以便在正确的语法附近使用，产品p WHERE to.productid = p.productid AND to.ipaddress =＆＃39; :: 1＆＃39;和to.or＆＃39;在第1行

Answer 1

TO（你用作ALIAS）在MySQL中是reserved word，你需要在反引号中包围它。

从查询的一部分......

e as price from temporder to, products p WHERE to
                         ^^^^ //<----- That's a reserved word. !

将它们包裹在下方的反击下..

e as price from temporder `to`, products p WHERE to

Answer 2

to是保留关键字

所以你需要将它包装在反引号中

`to`
