Bcp is a command line tool used in SQL Server to import and export data. It is based on DB-Library and can efficiently import and export large batches of data in parallel. Bcp can be used to export tables or views of a database, or filter tables or views using the select from statement to export them. When importing and exporting data, you can use the default value or use a
