How Can I Execute Large SQL Scripts with GO Commands in C#?

Efficiently Running Large SQL Scripts with GO Commands in C#

Database management often involves executing SQL scripts containing GO commands to separate batches. Directly using SqlCommand.ExecuteNonQuery() presents challenges when dealing with these scripts.

Leveraging SQL Server Management Objects (SMO)

A robust approach utilizes SQL Server Management Objects (SMO). SMO inherently handles GO separators, simplifying script execution. The ServerContext class within SMO provides a straightforward method for this purpose.

Here's an example using SMO:

using Microsoft.SqlServer.Management.Common;
using Microsoft.SqlServer.Management.Smo;

// Establish a connection to the SQL Server instance
using (SqlConnection connection = new SqlConnection(sqlConnectionString))
{
    // Create a Server object
    Server server = new Server(new ServerConnection(connection));

    // Execute the SQL script
    server.ConnectionContext.ExecuteNonQuery(script);
}

Alternative Solution: Haacked's Library

If SMO isn't feasible, Phil Haack's library offers an alternative for managing GO statements:

using Haacked.Sql;

// Execute the script using Haacked's library
BatchScript.Run(sqlConnectionString, script);

Summary

SMO or Haack's library provide efficient and reliable methods for executing large SQL scripts containing GO commands in C#, eliminating the complexities of manual batch separation. Choose the method best suited to your project's dependencies and requirements.
