Question

我试图运行此查询：

$result = db_query("INSERT INTO `timesheets` (clientid, candid, weekending, department, orderno, basicpay, basiccharge, otpay, otcharge, ot2pay, ot2charge, status, hue, huc) VALUES (`$client`, `$cand`, `$week_ending`, `$department`, `$order_no`, `$basic_pay`, `$basic_charge`, `$ot_pay`, `$ot_charge`, `$ot2_pay`, `$ot2_charge`, `$status`, `$hue`, `$huc`)");
    if($result){
        print 'Success! ID of last inserted record is';
    } 
    else {
        die('Error : ' . db_error());
    }

这些是

形式的值

    $client = db_quote($_POST['client']);
    $cand = db_quote($_POST['cand']);
    $order_no = db_quote($_POST['order_no']);
    $department = db_quote($_POST['department']);
    $week_ending = db_quote($_POST['week_ending']);
    $basic_pay = db_quote($_POST['basic_pay']);
    $hue = db_quote($_POST['hue']);
    $basic_charge = db_quote($_POST['basic_charge']);
    $huc = db_quote($_POST['huc']);
    $ot_pay = db_quote($_POST['ot1_pay']);
    $ot_charge = db_quote($_POST['ot1_charge']);
    $ot2_pay = db_quote($_POST['ot2_pay']);
    $ot2_charge = db_quote($_POST['ot2_charge']);   
    $status = 'cand';

此实例中$client的值为＆＃34; 725＆＃34;。我得到的错误是错误：未知栏＆＃39;＆＃39;＆nbsp;＆＃39;＆＃39;＆＃39;＆＃39;在＆＃39;字段列表＆＃39;。

这怎么可能 - 时间表表格中的列名是clientid。我试图将值725放入clientid列。某处有语法错误吗？错误信息似乎没有意义吗？

Answer 1

正确的查询将如下所示：

$rootScope

Answer 2

在MySQL中设置值时，您无法使用反引号字符来表示字段，您需要使用'或"来包含变量。

使用反向标记用于命名字段。这是MySQL的一个怪癖。

您的查询行应为：

$result = db_query("INSERT INTO `timesheets` (clientid, candid, weekending, department, orderno, basicpay, basiccharge, otpay, otcharge, ot2pay, ot2charge, status, hue, huc) VALUES ('$client', '$cand', '$week_ending', '$department', '$order_no', '$basic_pay', '$basic_charge', '$ot_pay', '$ot_charge', '$ot2_pay', '$ot2_charge', '$status', '$hue', '$huc')");

Answer 3

试试这种方式

tempString = (string("cmd.exe /C \"") + tempString + "\"");

STARTUPINFO si = { sizeof(STARTUPINFO) };

PROCESS_INFORMATION pi;

CreateProcess(NULL, (LPSTR)tempString.c_str(), 0, 0, FALSE, CREATE_UNICODE_ENVIRONMENT, NULL, 0, &si, &pi);

Answer 4

请在创建查询时注意引号。

INSERT 语句应该是这样的：

INSERT INTO table_name (col_name_1, col_name_2, col_name_3) VALUES('$param_1', '$param_2', '$param_3')

请注意，table_name不带引号，而每个值都用单引号分隔。

您可以找到官方文档here和完整示例here。

顺便说一下，对代码的查询应该是这样的：

 $sqlQuery = "INSERT INTO timesheets (clientid, candid, weekending, department, orderno,basicpay, basiccharge, otpay, otcharge, ot2pay, ot2charge, status, hue, huc) VALUES ('$client', '$cand', '$week_ending', '$department', '$order_no', '$basic_pay', '$basic_charge', '$ot_pay', '$ot_charge', '$ot2_pay', '$ot2_charge', '$status', '$hue', '$huc')";

SQL语法错误：未知列
