我正在做的是使用一个表单并将数据插入到2个表中。我试过运行它我一直得到“你的SQL语法有错误;检查与你的MySQL服务器版本相对应的手册，以便在第1行附近使用正确的语法”

我问是否可以在一个php文件中执行2个查询？

Answer 1

你错过了大括号（）。试试这个：

$query = "INSERT INTO persons(ID, FirstName , LastName , Email)VALUES ('$ID' ,'$fname', '$lname', '$email')";
$query1 = "INSERT INTO members (ID , username , password)VALUES ('$ID' , '$username' , '$password')";

Answer 2

是的，您可以根据需要运行任意数量的查询。
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 '' at line 1

这是查询错误，意味着您尝试运行的查询存在一些问题，而不是运行两个ueries。

3错误即将发生，因为插入查询的正确语法如下：

    INSERT INTO table_name (column1, column2, column3,...) VALUES (value1, value2, value3,...)

现在，将您的查询与此语法匹配，并尝试直接在您的xampp sql中运行它，这将解决问题。

第一个查询中的额外括号（外括号）正在产生问题。删除它们，你很高兴

Answer 3

您的第一个插入语句有问题

$query  = "INSERT INTO persons(ID, FirstName , LastName , Email)VALUES ('$ID' ,'$fname', '$lname', '$email')";
$query1 = "INSERT INTO members (ID , username , password)VALUES ('$ID' , '$username' , '$password')";

Answer 4

没有规则在单个php文件中写入sql查询没有意味着你可以编写任意数量的

使用2个查询登记表
