Export BCP to CSV

Jump to


    Welcome to your comprehensive guide on exporting BCP (Bulk Copy Program) to CSV filesā€”a vital process for efficiently managing and analyzing large volumes of data. By leveraging BCP, a client utility for T-SQL, users can expedite the transfer of data from database tables directly into CSV files, making it easier than ever to load data into spreadsheets for a variety of analytical purposes. On this page, we'll delve into what BCP is, the step-by-step process of exporting BCP to a CSV file, practical use cases, and an innovative alternative to traditional CSV exports using Sourcetable. Additionally, we will answer common questions about exporting BCP to CSV, helping you streamline data handling and maximize productivity.

    Understanding BCP

    BCP refers to a set of tools and practices that are essential in different contexts. In the realm of software, BCP stands for Business Continuity Management Program, and BCMP solutions are utilized to manage the various phases of the Business Continuity Management (BCM) life cycle. These phases include planning, activation, and crisis management. BCMP solutions offer a comprehensive approach to assess availability risks, conduct business impact analyses (BIA), and map dependencies. They also facilitate the management of recovery plans and the analysis of BCM metrics, as defined by industry analysts like Gartner.

    In the context of services, BCP is synonymous with the Book of Common Prayer, which is integral to the Church of England's worship and doctrinal foundation. The Book of Common Prayer is known for its compelling language and services, and there is guidance available, such as videos from the Prayer Book Society, for conducting these services.

    When discussing data, BCP represents the bulk copy program utility, which is instrumental in the efficient transfer of data between an instance of SQL Server and a user-specified data file. This utility allows for the quick import and export of data without the need for in-depth knowledge of Transact-SQL, and it is compatible with various versions of SQL Server, including Azure SQL and SQL Server 2022+.

    Exporting Data with BCP to a CSV File

    Using Command Line Utility

    BCP is a command line utility that facilitates the transfer of data between SQL servers and enables the creation of CSV files. To create a CSV file using BCP, you must use the -c switch to output in ASCII format, which is the default format BCP uses. To specify a field terminator, the -t switch is required, and this is particularly important if the data includes commas, in which case a different delimiter must be used. A trusted connection can be established using the -T switch, and the -S switch is necessary to specify the server connection information.

    Executing BCP from T-SQL

    BCP commands can be executed from within T-SQL using the xp_cmdshell stored procedure. This method allows for the extraction of data from tables, views, or stored procedures into a CSV file. When executing BCP from T-SQL, it is possible to use the native data format switches -n or -N for faster data transfer and to avoid conversion problems.

    Using Stored Procedures

    The BCP process can be controlled and automated with the use of stored procedures. A specific stored procedure, such as s_bcpMasterSysobjects, can be used to allocate an identifier for the data extraction process. This identifier is then passed to a format stored procedure, which inserts the extracted data into a table associated with that identifier. Following the data insertion, another stored procedure or in-line code can be called to create CSV files for each identifier, separating the file creation process from the data extraction process.

    Creating Files for Each Identifier

    Using BCP, files can be independently created for each identifier. The data extraction is performed first, and the resultant files are then created using the BCP utility. This method allows for organized and efficient exporting of data to individual CSV files, especially when dealing with multiple tables or datasets within a database.

    Frequently Asked Questions

    How do I handle importing and exporting large amounts of data using BCP?

    For exporting data, use the syntax 'bcp [db_name].[schema_name].[table_name] out [data_file] -c -T'. For importing data, use 'bcp [db_name].[schema_name].[table_name] in [data_file] -c -T'. The -T flag uses a trusted connection, the -c flag specifies character type data, and the -S option specifies the server name/instance.

    What does the -k option do in BCP?

    The -k option in BCP manages null values by preserving them during the import or export process. It prevents null values from being replaced with default values, which is useful for databases where null and default values have different meanings.

    How does BCP handle Unicode data?

    BCP handles Unicode data differently from non-Unicode data by using a native format for Unicode data.

    Can BCP be automated?

    Yes, BCP can be automated with scripting and scheduling. Scheduling tools like Windows Task Scheduler or cron can run BCP scripts. For more advanced control flow, error handling, and transformation capabilities, SSIS can be used to automate BCP.

    Why would someone use a comma as a delimiter in BCP, and what are the alternatives?

    A comma is often used as a delimiter because it is a standard practice in CSV files. However, if the data contains commas, it might be better to use a different delimiter by specifying the -t switch. Alternatives like a pipe '|' or a tab can be used, or another tool than BCP might be suggested for handling such cases.


    BCP, or Bulk Copy Program, is a highly efficient and effective client utility for exporting data from SQL Server to CSV files, offering a simplified and faster alternative compared to DTS or SSIS. By utilizing BCP's command-line interface and its compatibility with T-SQL's xp_cmdshell, users can leverage the power of stored procedures and views to precisely format and control the data extraction process. Best practices include using the native data format for seamless data transfers and employing a controlling stored procedure for a streamlined and organized export operation. Instead of exporting to CSV, consider the convenience of using Sourcetable to import data directly into a spreadsheet, enhancing your productivity and data management.
