Advanced SQL Server Data Movement - Bulk Copy Program (BCP)

Introduction

The Bulk Copy Program (BCP) is a command-line utility provided by SQL Server that allows for efficient and high-speed data movement between SQL Server and external data sources. This guide explores advanced techniques for using BCP to import and export data, including sample code and examples.

1. BCP Overview

Understand the basics of BCP, its capabilities, and its use cases in SQL Server data movement.

        -- Export Data with BCP
        bcp YourDatabase.dbo.YourTable out C:\Data\YourData.txt -S YourServer -T -c
    

2. Data Export with BCP

Learn how to use BCP to export data from SQL Server tables to external files or destinations.

        -- Export Data with BCP
        bcp YourDatabase.dbo.YourTable out C:\Data\YourData.txt -S YourServer -T -c
    

3. Data Import with BCP

Implement BCP to import data from external files into SQL Server tables with various data formats.

        -- Import Data with BCP
        bcp YourDatabase.dbo.YourTable in C:\Data\YourData.txt -S YourServer -T -c
    

4. BCP Format Files

Explore the use of format files to control data format and mapping during BCP operations.

        -- Use BCP Format Files
        bcp YourDatabase.dbo.YourTable format nul -S YourServer -T -n -f C:\Data\YourFormatFile.fmt
    

5. Advanced Use Cases

Advanced BCP usage may involve bulk insert with batch size control, data transformation, and data synchronization.
