There are many ways to import data from an Excel file to a SQL Server database using:

有多种方法可以使用以下方法将数据从Excel文件导入SQL Server数据库：

• SQL Server Integration Services (SSIS) SQL Server集成服务（SSIS）
• OPENROWSET and OPENROWSET和OPENDATASOURCE functions OPENDATASOURCE函数
• SQL Server linked servers SQL Server链接服务器
• SQL Server Import and Export Wizard SQL Server导入和导出向导

In this article, steps for importing data from an Excel file to a SQL Server database will be explained using the SQL Server Import and Export Wizard including some of problems that can occur during the processes.

在本文中，将使用SQL Server导入和导出向导解释将数据从Excel文件导入SQL Server数据库的步骤，其中包括在处理过程中可能发生的一些问题。

To start the process of importing data from an Excel file to a SQL Server database using the SQL Server Import and Export Wizard the SQL Server Import and Export Wizard needs to be launched. There are several ways to do that, and this can be seen on the How to import/export data to SQL Server using the SQL Server Import and Export Wizard page

要开始使用SQL Server导入和导出向导将数据从Excel文件导入SQL Server数据库的过程，需要启动SQL Server导入和导出向导。 有几种方法可以执行此操作，这可以在如何使用“ SQL Server导入和导出向导”页面向SQL Server导入/导出数据中看到。

The first page that appears when the SQL Server Import and Export Wizard launched is Welcome page:

启动SQL Server导入和导出向导时出现的第一页是欢迎页面：

On this page, only a quick introduction of the SQL Server Import and Export Wizard is shown.

在此页面上，仅显示SQL Server导入和导出向导的快速介绍。

Click the Next button to continue. The next page in the SQL Server Import and Export Wizard is Choose a Data Source page:

单击下一步按钮继续。 SQL Server导入和导出向导的下一页是“选择数据源”页面：

In the Choose a Data Source page, in order to continue with importing data from Excel to SQL Server the data source provider and way of connecting with data source must be provided. In our case, the provider for connecting to the Excel file is the Microsoft Excel provider.

在“ 选择数据源”页面中，为了继续将数据从Excel导入SQL Server，必须提供数据源提供程序和与数据源的连接方式。 在我们的情况下，用于连接到Excel文件的提供程序是Microsoft Excel提供程序。

From the Data source drop down box, select the Microsoft Excel provider:

从数据源下拉框中，选择Microsoft Excel提供程序：

As you can see, there is no Microsoft Excel provider in the list of the Data source drop down box. There are several reasons for this. The first reason could be that Microsoft Office isn’t installed. But there is no need to install Microsoft Office (Microsoft Excel) in order to see the Microsoft Excel provider in the Data source drop down box list.

如您所见，数据源下拉框列表中没有Microsoft Excel提供程序。 有几个原因。 第一个原因可能是未安装Microsoft Office 。 但是无需安装Microsoft Office（Microsoft Excel）即可在“数据源”下拉框列表中查看Microsoft Excel提供程序。

To see the Microsoft Excel provider in the list, install Microsoft Access Database Engine 2016 Redistributable. The latest version of Microsoft Access Database Engine can open the earlier version of Excel, so make sure that you have the latest one.

若要在列表中查看Microsoft Excel提供程序，请安装Microsoft Access数据库引擎2016 Redistributable 。 最新版本的Microsoft Access数据库引擎可以打开早期版本的Excel，因此请确保您拥有最新版本的Excel。

The Microsoft Access Database Engine 2016 Redistributable comes with two versions:

Microsoft Access数据库引擎2016 Redistributable具有两个版本：

• AccessDatabaseEngine.exe is 32-bit version AccessDatabaseEngine.exe是32位版本
• AccessDatabaseEngine_X64.exe is 64-bit version AccessDatabaseEngine_X64.exe是64位版本

Now, when Microsoft Access Database Engine 2016 Redistributable is installed, we should see the Microsoft Excel provider in the list, but unfortunately the Microsoft Excel provider does not show in the list of the Data source drop down box.

现在，在安装Microsoft Access Database Engine 2016可再发行组件后 ，我们应该在列表中看到Microsoft Excel提供程序，但是不幸的是，Microsoft Excel提供程序没有显示在“数据源”下拉框的列表中。

This is because you may run a wrong version of the SQL Server Import and Export Wizard. For example, the AccessDatabaseEngine.exe is installed and the SQL Server Import and Export Wizard 64-bit version is launched. In this case, in order to see the Microsoft Excel provider in the list of the Data source drop down box, launch the SQL Server Import and Export Wizard 32-bit version and the Microsoft Excel provider will appear in the list:

这是因为您可能运行了错误版本SQL Server导入和导出向导。 例如，安装AccessDatabaseEngine.exe并启动SQL Server导入和导出向导64位版本。 在这种情况下，为了在数据源下拉列表的列表中看到Microsoft Excel提供程序，请启动SQL Server导入和导出向导32位版本，并且Microsoft Excel提供程序将出现在列表中：

Now, when all is installed, from the list, select the Microsoft Excel provider. On the Choose a Data Source page, additional options appear:

现在，在全部安装后，从列表中选择Microsoft Excel提供程序。 在“ 选择数据源”页面上，出现其他选项：

In the Excel file path box, type the location to the Excel file or use the Browse button to navigate to the location:

在“ Excel文件路径”框中，键入Excel文件的位置，或使用“ 浏览”按钮导航到该位置：

From the Excel version drop down box, choose the version of Excel that uses the source workbook. In our case, that is the Microsoft Excel 2016 version:

从“ Excel版本”下拉框中，选择使用源工作簿的Excel版本。 在我们的案例中，这是Microsoft Excel 2016版本：

The latest option on this page is the First row has column names check box:

此页面上的最新选项是“ 第一行具有列名”复选框：

By default, this option is checked. It treads the first rows of the data source as the column names:

默认情况下，此选项处于选中状态。 它将数据源的第一行作为列名称：

But if this option is enabled and data source does not contain column names, the SQL Server Import and Export Wizard will add the column names, starting with the name F1 for the first column name:

但是，如果启用此选项，并且数据源不包含列名，则SQL Server导入和导出向导将添加列名，第一个列名以名称F1开始：

If this option is disabled and data source contain the column names the SQL Server Import and Export Wizard treats these columns as the first row of data:

如果禁用此选项，并且数据源包含列名，则SQL Server导入和导出向导会将这些列视为数据的第一行：

Now, when everything is set on the Choose a Data Source page of the SQL Server Import and Export Wizard, click the Next button to continue.

现在，在“ SQL Server导入和导出向导”的“选择数据源”页面上完成所有设置后，单击“ 下一步”按钮继续。

The following warning message may appear after clicking the Next button:

单击下一步按钮后，可能会出现以下警告消息：

The operation could not be completed.

操作无法完成。

Additional information:

附加信息：

The ‘Microsoft.ACE.OLEDB.16.0’ provider is not registered on the local machine. (System.Data)

“ Microsoft.ACE.OLEDB.16.0”提供程序未在本地计算机上注册。 （系统数据）

Typically, this warning message appears when the SQL Server Import and Export Wizard is launched via SQL Server Management Studio (SSMS) which is a 32-bit application and the 32-bit version of the SQL Server Import and Export Wizard is launched, but you have installed the Microsoft Access Database Engine 2016 Redistributable 64 bit version.

通常，当SQL Server导入和导出向导通过启动出现此警告消息SQL Server Management Studio中（SSMS），这是一个32位应用程序和的32位版本的SQL Server导入和导出向导启动，但你已安装Microsoft Access数据库引擎2016可再发行的 64位版本。

There are two solutions for resolving this problem:

有两种解决此问题的方法：

• SQL Server Import and Export Wizard via the 开始”菜单启动64位版本的Start menu SQL Server导入和导出向导
• The second resolution is to install the Microsoft Access Database Engine 2016 Redistributable 32 bit version and continue using the SQL Server Import and Export Wizard via SSMS, but first, you need to uninstall the 64-bit version of Microsoft Access Database Engine 2016 Redistributable, otherwise the following warning message will appear when launching the installation package:
• 第二种解决方法是安装Microsoft Access Database Engine 2016 Redistributable 32位版本，并继续通过SSMS使用SQL Server导入和导出向导 ，但是首先，您需要卸载64位版本的Microsoft Access Database Engine 2016 Redistributable，否则启动安装程序包时，将出现以下警告消息：

Note: The Microsoft Access Database Engine 2016 Redistributable can be installed in quiet mode.

注意 ：可以以安静模式安装Microsoft Access Database Engine 2016可再发行组件。

Open the Command Prompt window and run the following:

打开命令提示符窗口，然后运行以下命令 ：

For 32-bit version

对于32位版本

C：\ Users \ <用户名> \ Downloads \ AccessDatabaseEngine_X64.exe / quiet

The next page on the SQL Server Import and Export Wizard is the Choose a Destination page:

SQL Server导入和导出向导的下一页是“ 选择目标”页：

On this page, determine the destination where data from the data source (Excel file) will be placed. In our case, the destination will be a SQL Server database.

在此页面上，确定将放置数据源（Excel文件）中的数据的目的地。 在我们的例子中，目标将是SQL Server数据库。

Under the Destination drop down box, choose a provider that can connect to a SQL Server database.

在“ 目标”下拉框中，选择可以连接到SQL Server数据库的提供程序。

One of providers that can connect to SQL Server is:

可以连接到SQL Server的提供程序之一是：

• NET Framework Data Provider for SqlServer 用于SqlServer的NET Framework数据提供程序
• Microsoft OLE DB Provider for SQL Server 用于SQL Server的Microsoft OLE DB提供程序
• SQL Server Native Client 11.0 SQL Server本机客户端11.0

In this case, the SQL Server Native Client 11.0 will be selected from the Destination list:

在这种情况下，将从“ 目标”列表中选择“ SQL Server Native Client 11.0 ” ：

From the Server name combo box, select the SQL Server instance:

从服务器名称组合框中，选择SQL Server实例：

In the Authentication section, determine how it will be connected to SQL Server by using Windows or SQL Server Authentication mode.

在“ 身份验证”部分中，确定如何使用Windows或SQL Server身份验证模式将其连接到SQL Server。

From the Database drop down box, pick a database in which data from data source (Excel file) will be placed:

在“ 数据库”下拉框中，选择一个数据库，其中将放置来自数据源（Excel文件）的数据：

Or, create a new database as a destination for data from data source.

或者，创建一个新数据库作为数据源中数据的目标。

To do that, click the New button and in the Create Database dialog, set the parameters for the new SQL Server destination database:

为此，请单击“ 新建”按钮，然后在“ 创建数据库”对话框中，为新SQL Server目标数据库设置参数：

When everything is set on the Choose a Destination page, click the Next button to proceed.

在“ 选择目标”页面上设置完所有内容后，单击“ 下一步”按钮继续。

On the Specify Table Copy or Query page, determine how data from the data source will be copied to the destination:

在“ 指定表副本或查询”页面上，确定如何将数据源中的数据复制到目标：

If the Copy data from one or more tables or views radio button is selected then all data from the chosen worksheets will be copied.

如果选中“从一个或多个表或视图复制数据”单选按钮，则将复制所选工作表中的所有数据。

If the Write a query to specify the data to transfer is chosen, then only data that are specified in a SQL query will be copied from an Excel worksheet to a destination SQL Server database.

如果选择了“ 编写查询以指定要传输的数据” ，则仅将SQL查询中指定的数据从Excel工作表复制到目标SQL Server数据库。

If the Write a query to specify the data to transfer in the Choose a Destination page is chosen, then the Provide a Source Query page will be shown when the Next button is pressed:

如果在“ 选择目标”页面中选择了“ 编写查询以指定要传输的数据 ” ，那么在按下“ 下一步”按钮时将显示“ 提供源查询”页面：

In the SQL statement text box, type the query that will select the data to copy form the Excel file to the SQL Server database or load a query using the Browse button.

在“ SQL语句”文本框中，键入查询，该查询将选择要从Excel文件复制到SQL Server数据库的数据，或使用“ 浏览”按钮加载查询。

To successfully query a worksheet the $ to the end of the sheet name and the brackets around sheet name, ([BusinessEntity$]) must be added, otherwise the following warning messages may appear:

为了成功地查询工作表中$到片材名称的末尾和周围表名称的括号，必须添加（[$的BusinessEntity]），否则以下警告消息可能出现：

The statement could not be parsed.

该语句无法解析。

Additional information:

附加信息：

The Microsoft Access database engine could not find the object ‘BusinessEntity’. Make sure the object exists and that you spell its name and the path name correctly. If ‘BusinessEntity’ is not a local object, check your network connection or contact the server administrator. (Microsoft Access Database Engine)

Microsoft Access数据库引擎找不到对象“ BusinessEntity”。 确保对象存在，并且正确拼写了它的名称和路径名。 如果“ BusinessEntity”不是本地对象，请检查您的网络连接或与服务器管理员联系。 （Microsoft Access数据库引擎）

Or this:

或这个：

If the Copy data from one or more tables or views radio button is chosen, when the Next button is pressed, the Select Source Tables and Views page will be shown:

如果选择了“从一个或多个表或视图复制数据”单选按钮，则按下“ 下一步”按钮时，将显示“ 选择源表和视图”页面：

On this page, all worksheets for the Excel file (ImportData.xlsx) will be listed under the Source column. From the Source list, choose from which worksheets you want to import data to the SQL Server database by clicking the check box next to the name of the worksheets. The selected worksheets will appear in the Destination column:

在此页面上，Excel文件（ImportData.xlsx）的所有工作表将在“ 源”列下列出。 在“源”列表中，通过单击工作表名称旁边的复选框，选择要将数据从哪个工作表导入SQL Server数据库。 所选的工作表将出现在“ 目标”列中：

The name of the tables in the SQL Server database by default will be the names of the selected worksheets from the Source column, but these names can be changed by clicking on the name in the Destination column:

默认情况下，SQL Server数据库中表的名称将是“ 源”列中所选工作表的名称，但是可以通过单击“ 目标”列中的名称来更改这些名称：

As it may be noticed, the icon in the Destination column for the BusinessEntity$ field is different from the Table1 and Table2 fields. This is because the table in the SQL Server database that is chosen as a destination already exists and for the Table1 and Table2 fields, new tables will be created.

可能已经注意到， BusinessEntity $字段的“目标”列中的图标与Table1和Table2字段不同。 这是因为选择作为目标SQL Server数据库中的表已经存在，并且对于Table1和Table2字段，将创建新表。

When using an existing table, make sure that the destination table has the same number of columns that have data source, otherwise the columns from the data source that does not have an adequate destination column will be by default ignored (<ignore>) and the data from that columns will not be imported to a destination table:

使用现有表时，请确保目标表具有相同数目的具有数据源的列，否则，默认情况下将忽略数据源中没有足够目标列的列（ <ignore> ），并且该列中的数据不会导入到目标表中：

Also, make sure that columns in the destination table have data types that are compatible with the data types in the columns of the source data, otherwise the following error may appear:

另外，请确保目标表中的列具有与源数据的列中的数据类型兼容的数据类型，否则可能会出现以下错误：
