MSSQL数据库快速导出SQL文件

Introduction

When it comes to databases, the amount of data stored in it can be overwhelming and sometimes, we need to backup or export this data. One way to export data from a Microsoft SQL Server database is to create an SQL file. In this article, we will discuss how to quickly export an SQL file from an MSSQL database.

Export SQL file using SQL Management Studio

SQL Management Studio is a graphical tool that allows you to manage your MSSQL database. To export an SQL file from the database using this tool, follow the following steps:

Step 1: Connect to your MSSQL database using SQL Management Studio

To connect to your database using SQL Management Studio, do the following:

Open SQL Management Studio.

Click on the "Connect" button at the top of the window.

In the "Connect to Server" window that appears, fill in the necessary details like the server name, login credentials, and database name.

Click on the "Connect" button to connect to your database.

Step 2: Export the SQL file

Once you have connected to your database, do the following to export your SQL file:

Right-click on the database that you want to export.

Click on "Tasks" in the context menu that appears.

Click on "Generate Scripts" in the next context menu.

The "Generate and Publish Scripts" wizard will appear. Click "Next" to proceed.

Choose the objects that you want to include in your script. You can select individual tables or the entire database. Click "Next" to proceed.

Choose the output location of your script. You can save it to a file or the clipboard. Click "Next" to proceed.

SELECT * FROM employees;

SELECT * FROM customers;

Select the advanced options that you need. Click "Next" to proceed.

Review your selections on the "Summary" page. Click "Next" to begin scripting.

When the script generation is complete, click "Finish".

Export SQL file using SQLCMD command line tool

Another way to export an SQL file from your MSSQL database is using the SQLCMD command line tool. This tool is a command line version of SQL Management Studio and can be used to execute scripts in the command prompt. To export an SQL file using SQLCMD, do the following:

Step 1: Open the command prompt

To open the command prompt, do the following:

Press the "Windows key + R" on your keyboard.

Type "cmd" in the "Run" window that appears.

Click "OK"

Step 2: Connect to your MSSQL database using SQLCMD

To connect to your MSSQL database using SQLCMD, do the following:

Type "SQLCMD -S servername -U username -P password" in your command prompt, where "servername" is the name of your server, "username" is your login username, and "password" is your login password. Press "Enter" to proceed.

Type "USE databasename" to switch to the database that you want to export.

Step 3: Export the SQL file

Once you have connected to your database, do the following to export your SQL file:

Type "SQLCMD -S servername -U username -P password –d databasename -Q "SELECT * FROM tablename" -o "C:\backup.sql"" in your command prompt to export the table "tablename" to a file named "backup.sql".

The SQL file will be saved in the directory specified in the command. You can open this file using any text editor.

Conclusion

Exporting an SQL file from an MSSQL database is a simple process that can be done using SQL Management Studio or SQLCMD. Both methods have their advantages and disadvantages and you can choose the one that best suits your needs. With these tools, you can easily backup your database and ensure that your valuable data is safe.
