Hi readers, welcome to this journal article about SQL Server Export as CSV. In this article, we will discuss everything you need to know about exporting data from SQL Server as CSV files. CSV files are a widely used format for exchanging data between different applications. There are several ways to export data from SQL Server as CSV files, and we will explore all of them in this article.
What is CSV, and why is it important?
CSV stands for Comma Separated Values. It is a file format that stores data in plain text. Each line of the file represents a single row of data, and each value in the row is separated by a comma. The first row typically contains the column headers. CSV files are widely used in data exchange because they are simple, lightweight, and can be read by most applications.
CSV files can be easily opened in spreadsheet applications like Microsoft Excel, Google Sheets, and LibreOffice Calc. They can also be used in programming languages like Python, R, and Java. Many web applications also use CSV files for data exchange.
How to export data from SQL Server as CSV?
There are several ways to export data from SQL Server as CSV files:
| Method | Description |
|---|---|
| Using the SQL Server Import and Export Wizard | The SQL Server Import and Export Wizard is a graphical tool that allows you to export data from SQL Server to various formats, including CSV. You can select the tables or views you want to export and specify the destination file and format. |
| Using the bcp utility | The bcp (bulk copy program) utility is a command-line tool that allows you to bulk copy data between SQL Server instances or between SQL Server and a file. You can use the bcp utility to export data from SQL Server to a CSV file. |
| Using SQLCMD | SQLCMD is a command-line tool that allows you to execute SQL scripts and commands from the command prompt. You can use SQLCMD to execute a SELECT statement and redirect the output to a CSV file. |
| Using the SSIS package | The SQL Server Integration Services (SSIS) package is a tool that allows you to extract, transform, and load data between different sources. You can use the SSIS package to export data from SQL Server to a CSV file. |
Using the SQL Server Import and Export Wizard
The SQL Server Import and Export Wizard is one of the easiest ways to export data from SQL Server as CSV files. To use the wizard, follow these steps:
- Open SQL Server Management Studio and connect to your SQL Server instance.
- Right-click on the database you want to export data from and select Tasks -> Export Data.
- In the SQL Server Import and Export Wizard, select the data source. You can choose from several options, including SQL Server, Flat File, and Excel.
- Select the tables or views you want to export. You can also specify a custom SQL query if you want to export data based on specific criteria.
- Specify the destination file and format. Choose “Flat File Destination” as the destination type and “CSV (Comma delimited)” as the file format. You can also specify the delimiter and text qualifier if you want to use different values than the defaults.
- Click “Next” and review the summary screen. You can also save the package if you want to reuse it later.
- Click “Finish” to start the export process. The wizard will display the progress and notify you when the export is complete.
Using the bcp utility
The bcp (bulk copy program) utility is a command-line tool that allows you to bulk copy data between SQL Server instances or between SQL Server and a file. To use the bcp utility to export data from SQL Server as CSV files, follow these steps:
- Open a command prompt and navigate to the directory where the bcp utility is installed. By default, it is located in the “C:\Program Files\Microsoft SQL Server\Client SDK\ODBC\130\Tools\Binn\” directory.
- Type the following command to export data from a table to a CSV file:
bcp "SELECT * FROM [table]" queryout "C:\path\to\file.csv" -S [server] -d [database] -T -c -t ,Replace “[table]” with the name of the table you want to export, “C:\path\to\file.csv” with the full path to the CSV file, “[server]” with the name of the SQL Server instance, and “[database]” with the name of the database.
The “-T” option specifies that you want to use Windows authentication to connect to SQL Server. If you want to use SQL Server authentication, replace “-T” with “-U [username] -P [password]”, and replace [username] and [password] with your credentials.
The “-c” option specifies that you want to use character mode to copy data. The “-t” option specifies the field terminator. In this case, we use a comma.
- Press Enter to execute the command. The bcp utility will export the data to the specified CSV file.
Using SQLCMD
SQLCMD is a command-line tool that allows you to execute SQL scripts and commands from the command prompt. To use SQLCMD to export data from SQL Server as CSV files, follow these steps:
- Open a command prompt and type the following command to execute a SELECT statement:
sqlcmd -S [server] -d [database] -E -s , -W -Q "SELECT * FROM [table]" > "C:\path\to\file.csv"Replace “[server]” with the name of the SQL Server instance, “[database]” with the name of the database, “[table]” with the name of the table you want to export, and “C:\path\to\file.csv” with the full path to the CSV file.
The “-E” option specifies that you want to use Windows authentication to connect to SQL Server. If you want to use SQL Server authentication, replace “-E” with “-U [username] -P [password]”, and replace [username] and [password] with your credentials.
The “-s” option specifies the field separator. In this case, we use a comma. The “-W” option specifies that we want to output in wide character format. The “> “C:\path\to\file.csv”” directs the output to a file.
- Press Enter to execute the command. SQLCMD will execute the SELECT statement and export the data to the specified CSV file.
Using the SSIS package
The SQL Server Integration Services (SSIS) package is a tool that allows you to extract, transform, and load data between different sources. To use the SSIS package to export data from SQL Server as CSV files, follow these steps:
- Open SQL Server Data Tools and create a new Integration Services project.
- Drag and drop a “Data Flow Task” from the toolbox to the design surface.
- Double-click on the “Data Flow Task” to open the data flow designer.
- Drag and drop an “OLE DB Source” from the toolbox to the design surface.
- Double-click on the “OLE DB Source” to configure the connection to SQL Server and select the table or view you want to export.
- Drag and drop a “Flat File Destination” from the toolbox to the design surface.
- Connect the “OLE DB Source” to the “Flat File Destination.”
- Double-click on the “Flat File Destination” to configure the destination file, format, and delimiter.
- Save and close the SSIS package.
- Right-click on the SSIS package and select “Execute Package” to start the export process.

FAQs
What is the best method to export data from SQL Server as CSV files?
There is no one-size-fits-all answer to this question. The best method depends on your specific requirements and preferences. The SQL Server Import and Export Wizard is a good option if you prefer a graphical interface. The bcp utility is a good option if you prefer command-line tools. SQLCMD is a good option if you want to execute SQL scripts from the command prompt. The SSIS package is a good option if you want to automate the export process.
Can I export data from SQL Server as CSV files using T-SQL?
No, T-SQL does not provide a native way to export data as CSV files. However, you can use SQL Server Management Studio to execute a SELECT statement and save the results as a CSV file.
How do I specify the encoding of the CSV file?
By default, CSV files are encoded in ANSI (Windows-1252) format. You can specify a different encoding by using a text editor or a programming language that supports encoding options. For example, you can specify UTF-8 encoding in Python by using the “utf-8-sig” encoding.
How do I import a CSV file into SQL Server?
You can import a CSV file into SQL Server using the SQL Server Import and Export Wizard or by writing a custom script or program in T-SQL or another programming language. The process of importing a CSV file involves mapping the columns in the CSV file to the columns in the target table and specifying the data types and formatting options.
