Introduction

Azure SQL Database provides a powerful tool for importing and exporting databases using the SQL Package. One of the most common use cases is importing a Bacpac file, which is a compressed package that contains the database schema and data. In this article, we will explore the process of importing a Bacpac file using the SQL Package and provide a step-by-step guide on how to specify the database maximum size.

What is a Bacpac File?

A Bacpac file is a compressed package that contains the database schema and data. It is a convenient way to export and import databases between different environments, such as development, testing, and production. The Bacpac file format is specific to Azure SQL Database and is not compatible with other database management systems.

Importing a Bacpac File Using SQL Package

To import a Bacpac file using the SQL Package, you will need to follow these steps:

Step 1: Install the SQL Package

The SQL Package is a command-line tool that is used to import and export databases. You can download the SQL Package from the official Microsoft website. Once you have downloaded the package, extract the contents to a folder on your computer.

Step 2: Run the SQL Package Command

To run the SQL Package command, open a command prompt or PowerShell window and navigate to the folder where you extracted the SQL Package. Then, run the following command:

sqlpackage.exe /a:Import /sf:your_bacpac_file.bacpac /tsn:your_server_name /tds:1433 /tu:your_username /tp:your_password /p:your_database_name

Replace the placeholders with your actual values:

  • your_bacpac_file.bacpac: the name of the Bacpac file you want to import
  • your_server_name: the name of your Azure SQL Database server
  • your_username: your Azure SQL Database username
  • your_password: your Azure SQL Database password
  • your_database_name: the name of the database you want to import into

Step 3: Specify the Database Maximum Size

By default, the SQL Package will automatically size the database to 32GB. However, if your actual database size is larger than 32GB, you will need to specify the database maximum size using the DatabaseMaximumSize parameter. To do this, add the following parameter to the SQL Package command:

sqlpackage.exe /a:Import /sf:your_bacpac_file.bacpac /tsn:your_server_name /tds:1433 /tu:your_username /tp:your_password /p:your_database_name /dms:your_database_maximum_size

Replace your_database_maximum_size with the actual size of your database in GB.

Example Use Case

Suppose you have a Bacpac file named my_database.bacpac that you want to import into an Azure SQL Database server named my_server. The database size is 40GB, and you want to specify the database maximum size to 40GB. You can use the following SQL Package command:

sqlpackage.exe /a:Import /sf:my_database.bacpac /tsn:my_server /tds:1433 /tu:my_username /tp:my_password /p:my_database /dms:40

Troubleshooting

If you encounter any issues during the import process, you can check the SQL Package logs for errors. The logs are stored in the sqlpackage.log file in the same folder where you ran the SQL Package command.

Conclusion

Importing a Bacpac file using the SQL Package is a powerful way to migrate databases between different environments. By following the steps outlined in this article, you can successfully import a Bacpac file and specify the database maximum size. Remember to replace the placeholders with your actual values and adjust the DatabaseMaximumSize parameter as needed.
