EonaCat.Sql

EonaCat Sql Builder and prevention library

Create SqlBuilder

SqlHelper.GetBuilder();

Check if the string is safe for web (Sql and Javascript)

// Without errors returned

SqlHelper.IsWebSafe(string input);

// With errors returned

SqlHelper.IsWebSafe(string input, out string errors);

// Only check for Sql injection

SqlHelper.HasSqlInjection(string input, out string errors);

// Only check for Javascript injection

SqlHelper.HasJsInjection(string input, out string errors);

You can also use it as a stringExtension:

if (!input.IsWebSafe())
{
    Console.WriteLine("String is NOT webSafe!");
}

if (input.HasSqlInjection(out string errors))
{
    Console.WriteLine($"String has Sql injections! {Environment.NewLine} {errors}");
}

if (input.HasJsInjection(out string errors))
{
    Console.WriteLine($"String has Javascript injections! {Environment.NewLine} {errors}");
}

Deadlock Retry Helper:

SqlHelper.DeadlockRetryHelper(Action action, int maxRetries = 3);

You can also use it as an actionExtension:

myMethodAction.DeadlockRetryHelper(3);

Execute SQL query directly parameterized:

private static async void TestsqlServer()
{
    var customerId = "AROUT";
    var result = SqlHelper.ExecuteQuery(
    new Microsoft.Data.SqlClient.SqlConnection(@"Server=localhost;Database=NorthWind;User Id=sa;Password=jeroen;TrustServerCertificate=Yes;"),
    $"SELECT * FROM Customers WHERE CustomerID = @CustomerId AND Country = @Country",
    new Dictionary<string, object>
    {
      { "CustomerId", customerId },
      { "Country", "UK" },
    }
);

    if (result.HasResult && result.HasRows)
    {
        Console.WriteLine($"Found '{result.TotalRows}' " + ((result.TotalRows > 1) ? "rows" : "row"));
        Console.WriteLine(string.Empty);
        foreach (var record in result.DataSet)
        {
            Console.WriteLine(record.CustomerID);
            Console.WriteLine(record.ContactTitle);
        }
    }
    else
    {
        if (!result.HasResult)
        {
            Console.WriteLine("No valid result!");
        }

        if (!result.HasRows)
        {
            Console.WriteLine("No rows found");
        }
        if (result.HasException)
        {
            Console.WriteLine(result.Exception);
        }
    }
    Console.ReadLine();
}
