How do you organize the process of exporting tables from a database?

For exporting tables from a database, I usually use the following approaches:

1. Using built-in DBMS tools — for example, mysqldump for MySQL, pg_dump for PostgreSQL. They allow exporting data and table structures to a file.

2. Via ORM or code — if export from a C# application is needed, Entity Framework can be used to fetch data and serialize it into the desired format (CSV, JSON, XML).

Example of exporting a table to CSV using C# and Entity Framework:

using (var context = new MyDbContext())
{
    var data = context.MyTable.ToList();
    using (var writer = new StreamWriter("export.csv"))
    {
        writer.WriteLine("Id,Name,Value");
        foreach (var item in data)
        {
            writer.WriteLine($"{item.Id},{item.Name},{item.Value}");
        }
    }
}

3. Using third-party tools — for example, SQL Server Management Studio, DBeaver, which allow exporting tables into various formats.

The choice of method depends on the task, data volume, and export format requirements.
