How Can I Execute SQL Script Files Using C#?

Running SQL Script Files from C#

This guide demonstrates several methods for executing SQL script files (.sql) within C# applications.

Method 1: Leveraging Microsoft SQL Server Management Objects (SMO)

SMO provides a powerful and reliable mechanism for managing SQL Server databases and executing scripts. The code example (not included here, but assumed to be present in the original answer) illustrates connecting to a database, reading a SQL script from a file, and executing it using the ExecuteNonQuery method of the ServerConnection object. This is generally the preferred approach for its robustness and integration with SQL Server.

Method 2: Utilizing SQLCMD (Command-Line Utility)

Alternatively, you can use the SQLCMD command-line utility to execute SQL scripts. This involves spawning a process to run SQLCMD with the appropriate parameters. Careful consideration should be given to error handling and ensuring the process completes successfully. Unlike using SMO, this method requires SQLCMD to be accessible on the system.

Important Considerations:

When choosing a method, weigh the benefits of each. SMO offers better integration and error handling, while using SQLCMD might be simpler for basic tasks if you already have it available. Always prioritize secure coding practices and appropriate error handling to prevent vulnerabilities and unexpected behavior.
