Delete data in SnowFlake using .NET

To delete data in Snowflake using .NET, you can use the Snowflake ADO.NET Data Provider. Here’s a sample code to delete data in Snowflake using C#:

using System;
using Snowflake.Data;

class Program
{
    static void Main()
    {
        // Set up the Snowflake connection string
        string connectionString = "ConnectionString";

        // Create a new Snowflake connection
        using (var connection = new SnowflakeDbConnection())
        {
            // Set the connection string
            connection.ConnectionString = connectionString;

            // Open the connection
            connection.Open();

            // Create a new command
            using (var command = connection.CreateCommand())
            {
                try
                {
                    // Set the SQL statement to delete data
                    command.CommandText = "DELETE FROM my_table WHERE condition = @condition";

                    // Add parameters to the command
                    command.Parameters.AddWithValue("@condition", "Some Condition");

                    // Execute the delete command
                    int rowsAffected = command.ExecuteNonQuery();

                    Console.WriteLine($"Rows deleted: {rowsAffected}");
                }
                catch (Exception ex)
                {
                    Console.WriteLine("Error: " + ex.Message);
                }
            }
        }
    }
}

In the code above, replace "ConnectionString" with the actual connection string to your Snowflake database.

The code uses the Snowflake ADO.NET Data Provider to establish a connection to Snowflake. It creates a new SnowflakeDbConnection object and sets the connection string.

Inside the using block, the connection is opened. Then, a new command is created using connection.CreateCommand(). The SQL statement is set in the command.CommandText property, where you can specify the table and conditions for the delete.

To specify the values for the delete, parameters are added to the command using command.Parameters.AddWithValue(). This helps prevent SQL injection and allows for parameterized queries.

The delete command is executed using command.ExecuteNonQuery(), which returns the number of rows affected by the delete operation.

Remember to handle any exceptions and dispose of the connection and command objects properly.
