我为学生创建了一份录取表，并尝试将信息保存到数据库中。我无法保存信息。请检查我在哪里做错了。

我收到此错误：
＆＃34; SELECT Error: 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 '77'' at line 1＆＃34;
请指导我做错的地方。提前致谢
答案 0 :(得分：1)
您的上一个查询有：
... VALUES (NULL, '$exam', '$ssc_school '$ssc_year', '$ssc_total_marks', ...
这是不正确的。它应该是：
... VALUES (NULL, '$exam', '$ssc_school', '$ssc_year', '$ssc_total_marks', ...
它也错过了右括号（正如其他人指出的那样）。
话虽如此：不再使用mysql_ *函数。他们是deprecated。请改为使用PDO或MySQLi与prepared statements。您目前对SQL injection attacks持开放态度。
答案 1 :(得分：1)
您的代码存在一些问题：
此'$ssc_sub', '$roll_number';")缺少一个括号，应为'$roll_number');")
加$_POSt t中的$_POSt['gender'];必须为大写$_POST，它是superglobal。
此外，'$ssc_school '$ssc_year',缺少引号和逗号，应该显示为'$ssc_school', '$ssc_year',
我也注意到你正在使用
(`S_No.`,
在一个查询中
(`S_No`,
在其他两个查询中。 S_No.＆lt; =中的点很可能不在那里。
如果它实际上是列的名称S_No.，那么您需要为其他两个查询添加点。
在mysql_error之上使用error reporting来表示代码中的错误。
error_reporting(E_ALL);
ini_set('display_errors', 1);
<强> 旁注：
您目前的代码向SQL injection开放。使用mysqli with prepared statements或PDO with prepared statements，他们更安全。
答案 2 :(得分：0)
您缺少值{/ 1>的结尾')'
$sql = mysql_query("INSERT INTO `school`.`academic` (`S_No.`, `Exam`, `School`, `Year`, `Total_marks`, `Marks_obtained`, `Grade`, `Percentage`, `Major_subjects`, `Roll_no`) VALUES (NULL, '$exam', '$ssc_school '$ssc_year', '$ssc_total_marks', '$ssc_marks', '$ssc_grade', '$ssc_percentage',
'$ssc_sub', '$roll_number';")or die("SELECT Error: ".mysql_error());
-------------------------^
尝试将其更改为
$sql = mysql_query("INSERT INTO `school`.`academic` (`S_No.`, `Exam`, `School`, `Year`, `Total_marks`, `Marks_obtained`, `Grade`, `Percentage`, `Major_subjects`, `Roll_no`)
VALUES (NULL, '$exam', '$ssc_school '$ssc_year', '$ssc_total_marks',
'$ssc_marks', '$ssc_grade', '$ssc_percentage', '$ssc_sub', '$roll_number');")
or die("SELECT Error: ".mysql_error());
也是巴特指出的
在$ ssc_school
之后的'中，您错过了VALUES (NULL, '$exam', '$ssc_school。
尝试添加
VALUES (NULL, '$exam', '$ssc_school'
答案 3 :(得分：-2)
更改您的查询并尝试编写如下
"INSERT INTO tbl (id, name) VALUES (" . $id . " , '" . $name . "')"
