尝试从特定日期获取费用列表,我可以在PHPMyAdmin中执行此SQL,但在页面上我收到MYSQL语法错误。
守则:
$full_date = date('d M Y', strtotime($date));
$get_expenses = mysql_query("SELECT Sum(cost) AS expense FROM expenses WHERE date = $full_date")or die(mysql_error());
$expenses = mysql_fetch_array( $get_expenses );
echo $expenses['expense'];
我收到的语法错误是:
您的SQL语法有错误;查看与您的MySQL服务器版本对应的手册,以便在第4行“2015年4月”附近使用正确的语法
我已查看$expenses['expense']
的值,并返回有效日期。在PHPMyAdmin中,我可以毫无问题地执行此SQL。有什么指针吗?干杯!

尝试这样,在将日期转换为相应格式之前,请执行此操作,
$get_expenses = mysql_query("SELECT Sum(cost) AS expense FROM expenses WHERE date = '$full_date'")or die(mysql_error());

SELECT Sum(cost) AS expense FROM expenses WHERE date = 13 Apr 2015
不是一个有效的查询,但它是你从该表达式获得的。
您应该使用引号括起值,例如:
$full_date = date('Y-m-d', strtotime($date));
$get_expenses = mysql_query("SELECT Sum(cost) AS expense FROM expenses WHERE date = '$full_date'") or die(mysql_error());
