为什么我在数据匹配时收到 "Insert value list does not match column list: 1136 Column count doesn't match value count" 错误？

Question

我收到上述错误，但我对要插入的列和数据的计数都是 19

try {
    $db = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
    $db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    $sql = "INSERT INTO prescriptions (
        rxID, rxPrimeName, rxAltName, patient, prescriber, dpp, dppMetric, totalDailyDosage, 
        totalDailyPills, frequency, freqMetric, am, noon, pm, bed, prn, pharmacy, lastFill, pills
        )
    VALUES 
        (
        '$rxID', '$drugName1', '$drugName2', '$patient', '$prescriber', '$dpp', '$metric', '$totalDailyDosage,
        $totalDailyPills', '$quantity', '$frequency', '$am', '$noon', '$pm', '$bed', '$prn', '$pharmacy', '$lastFill', '$pills'
        )";
    $db->exec($sql);
    echo "New record created successfully";
} catch (PDOException $e) {
    echo $sql . "<br>" . $e->getMessage();
}
$db = null;

这是我收到的确切错误：

INSERT INTO prescriptions ( rxID, rxPrimeName, rxAltName, patient, prescriber, dpp, dppMetric, totalDailyDosage, totalDailyPills, frequency, freqMetric, am, noon, pm, bed, prn, pharmacy, lastFill, pills ) VALUES ( '1111111', 'Test1', 'Test2', 'Jordan', 'Test3', '50', 'mg', '100, 2', '1', 'BID', '1', '1', '0', '0', '0', 'KJdh', '2022-04-15', '60' ) SQLSTATE[21S01]: Insert value list does not match column list: 1136 Column count doesn't match value count at row 1

双方（INSERT INTO和VALUES）有19

当我使用 phpMyAdmin 插入数据时，返回的内容如下：

INSERT INTO prescriptions (keyID, rxID, rxPrimeName, rxAltName, patient, prescriber, dpp, dppMetric, totalDailyDosage, totalDailyPills, frequency, freqMetric, am, noon, pm, bed, prn, pharmacy, lastFill, pills) VALUES (NULL, '1234567', 'Test1', 'Test2', 'Jordan', 'Test3', '30', 'mg', '60', '2', '1', 'BID', '1', '1', '0', '0', '0', 'Atrium', '2022-04-15', '60');

请原谅上面列名上的块 - 我在列名周围使用 backquote

phpMyAdmin 完美运行是的，我知道变量数据不同，但基于列的所有可接受类型

Answer 1

我数到18个。看起来你在 '100, 2',

处遗漏了 '

Answer 2

问题是您的 values 子句缺少引号：

VALUES 
(
'$rxID', '$drugName1', '$drugName2', '$patient', '$prescriber', '$dpp', '$metric',
'$totalDailyDosage, <-- missing quote before comma
-->> missing quote --> $totalDailyPills', 
'$quantity', '$frequency', '$am', '$noon', '$pm', '$bed', '$prn', '$pharmacy', '$lastFill', '$pills'
)";

为什么我在数据匹配时收到 "Insert value list does not match column list: 1136 Column count doesn't match value count" 错误？

Why am I getting a "Insert value list does not match column list: 1136 Column count doesn't match value count" error when the data matches?

php

mysql
