Question

我正在使用SELECT|INSERT|UPDATE某个表的简单MySQLi函数，但我无法使其工作。这是函数的代码：

function syncReps($fileName, $server, $user, $pass, $db)
{
    $conn = new mysqli($server, $user, $pass, $db);

    if ($conn->connect_error) {
        trigger_error('Database connection failed: '.$conn->connect_error, E_USER_ERROR);
    }

    $data = convertCsvToArray($fileName);
    echo "DEBUG count(data): ", count($data), "\n";

    // Processing on each row of data
    foreach ($data as $row) {
        $sql = 'SELECT id,lastSyncAt FROM reps WHERE veeva_rep_id = '.$row['Id'];
        echo "DEBUG: ", $sql, "\n";
        $rs = $conn->query($sql);

        if ($rs === false) {
            trigger_error('Wrong SQL: '.$sql.' Error: '.$conn->error, E_USER_ERROR);
        } else {
            $rows_returned = $rs->num_rows;
            $veeva_rep_id = "'".$conn->real_escape_string($row['Id'])."'";
            $first = "'".$conn->real_escape_string(ucfirst(strtolower($row['FirstName'])))."'";
            $last = "'".$conn->real_escape_string(ucfirst(strtolower($row['LastName'])))."'";
            $email = "'".$conn->real_escape_string($row['Email'])."'";
            $username = "'".$conn->real_escape_string($row['Username'])."'";
            $display_name = "'".$conn->real_escape_string(
                    ucfirst(strtolower($row['FirstName'])).' '.ucfirst(strtolower($row['LastName']))
                )."'";

            if ($rows_returned === 0) {
                $sql = "INSERT INTO reps(veeva_rep_id,first,last,email,username,lastLoginAt,lastSyncAt,display_name,rep_type,avatar_url) VALUES($veeva_rep_id,$first,$last,$email,$username,NOW(),NOW(),$display_name,'VEEVA','default_avatar.png')";
                echo "DEBUG: ", $sql, "\n";
                $conn->query($sql);
            } else {

            }
        }
    }
}

当我从CLI以php script.php执行脚本时，我得到了这个：

DEBUG count(data): 1454
DEBUG: SELECT id,lastSyncAt FROM reps WHERE veeva_rep_id = 00580000008ReolAAC

它首先在SELECT查询停止，为什么？如果$data计数为1454，则SELECT和INSERT $num_rows === 0不应该执行相同的function syncTerritories($fileName, $server, $user, $pass, $db) { $conn = new mysqli($server, $user, $pass, $db); if ($conn->connect_error) { trigger_error('Database connection failed: '.$conn->connect_error, E_USER_ERROR); } $data = convertCsvToArray($fileName); echo "DEBUG count(data): ", count($data), "\n"; // Processing on each row of data foreach ($data as $row) { $sql = "SELECT id FROM territories WHERE veeva_territory_id='{$row['Id']}'"; echo "DEBUG: ", $sql, "\n"; $rs = $conn->query($sql); if ($rs === false) { echo 'Wrong SQL: '.$sql.' Error: '.$conn->error, E_USER_ERROR; } else { $rows_returned = $rs->num_rows; $veeva_territory_id = "'".$conn->real_escape_string($row['Id'])."'"; $name = "'".$conn->real_escape_string($row['Name'])."'"; if ($rows_returned === 0) { $sql = "INSERT INTO territories(veeva_territory_id,territory_name,createdAt,updatedAt) VALUES($veeva_territory_id,$name,NOW(),NOW())"; echo "DEBUG: ", $sql, "\n"; $rs = $conn->query($sql); if ($rs === false) { echo 'Wrong SQL: '.$sql.' Error: '.$conn->error, E_USER_ERROR; } $rs->free(); } else { // UPDATE } } } }和DEBUG count(data): 6911 DEBUG: SELECT id FROM territories WHERE veeva_territory_id='04T800000008zy9EAA' DEBUG: SELECT id FROM territories WHERE veeva_territory_id='04T80000000903eEAA' DEBUG: SELECT id FROM territories WHERE veeva_territory_id='04T80000000TOTIEA4' DEBUG: INSERT INTO territories(veeva_territory_id,territory_name,createdAt,updatedAt) VALUES('04T80000000TOTIEA4','AKORN_101TM',NOW(),NOW())？我在这里缺少什么？

修改

我仍然遇到与其他功能类似的问题，请参阅下文：

buildozer --verbose android debug deploy run

输出如下：

现在有什么问题？应该从这种方式转变为准备好的陈述吗？如果是这样的话可以根据我的例子给我一些疑问吗？

这是一个无效的SQL字符串要执行。您需要将veeva_rep_id值包装在单引号中：

$sql = "SELECT id,lastSyncAt FROM reps WHERE veeva_rep_id='{$row['Id']}'";

为什么只有第一个SELECT被执行？
