Question

这是我的mysql查询代码，我想更改为sqlsrv查询以导入到sql server数据库

$message = null;

$allowed_extensions = array('csv');

$upload_path = '../csv';

if (!empty($_FILES['file'])) {

  if ($_FILES['file']['error'] == 0) {

    // check extension
    $file = explode(".", $_FILES['file']['name']);
    $extension = array_pop($file);

    if (in_array($extension, $allowed_extensions)) {

      if (move_uploaded_file($_FILES['file']['tmp_name'], $upload_path.'/'.$_FILES['file']['name'])) {

        if (($handle = fopen($upload_path.'/'.$_FILES['file']['name'], "r")) !== false) {

          $keys = array();
          $out = array();

          $insert = array();

          $line = 1;

          while (($row = fgetcsv($handle, 0, ',', '"')) !== FALSE) {

                foreach($row as $key => $value) {
                    if ($line === 1) {
                        $keys[$key] = $value;
                    } else {
                        $out[$line][$key] = $value;

                    }
                }

                $line++;

            }

            fclose($handle);    

            if (!empty($keys) && !empty($out)) {

                $db = new PDO('mysql:host=localhost;dbname=project', 'root', '');
                $db->exec("SET CHARACTER SET utf8");

                foreach($out as $key => $value) {

                    $sql  = "INSERT INTO `department` (`";
                    $sql .= implode("`, `", $keys);
                    $sql .= "`) VALUES (";
                    $sql .= implode(", ", array_fill(0, count($keys), "?"));
                    $sql .= ")";
                    $statement = $db->prepare($sql);
                    $statement->execute($value);

                }

                $message = '<span style="color:green">File has been uploaded successfully</span>';

            }   

        }

      }

    } else {
      $message = '<span style="color:red">Only .csv file format is allowed</span>';
    }

  } else {
    $message = '<span style="color:red">There was a problem with your file</span>';
  }

希望它能帮助您手动完成。

有时MS SQL表或列名称用方括号括在查询中（例如，如果包含空格或出于某些其他原因）。 MySQL不允许在列名表周围使用方括号，它们都必须由symbol or cut off: [object] -> object`替换。

所以你需要删除所有＆＃34;＆＃39;＆＃34;在上面的例子中，也来自表名部门及其列。更多。

您的SQL查询如下所示。请删除？标记也是。

                $sql  =   INSERT INTO department (;
                $sql .= implode(",", $keys);
                $sql .= ) VALUES (";
                $sql .= implode(", ", array_fill(0, count($keys), "?"));
                $sql .= ")";
                $statement = $db->prepare($sql);
                $statement->execute($value);

我对PHP不太了解。我只能帮助构造SQL查询。它应该是

"INSERT INTO department (COLUMN1,COLUMN2,..) values(VALUE1,VALUE1,..)".

添加了：

正如我已经告诉过你的那样，我不是一个PHP家伙。但是为你而战。请尝试您的PHP代码：

$sql = "INSERT INTO department (";
    $sql .= "implode(',', $keys)";
    $sql .= ") VALUES ("; 
    $sql .= "implode(',', array_fill(0, count($keys), ''))"; 
    $sql .= ")"; 
    $statement = $db->prepare($sql); $statement->execute($value);

但 array_fill（0，count（$ keys），＆＃39;＆＃39;）是空数据吗？

如何从mysql查询到sqlsrv查询导入到sql server数据库？
