EasySQL

Use this class library to execute your MS SQL queries in your C# programs easily without hassle.

Background

Do you find yourself writing a handful of codes to execute a single or number of SQL statement(s) in your C# program using System.Data.SqlClient? Do your code somewhat looks like this as follows:

    SqlConnection conn = new SqlConnection(SQLConnectionString);
    SqlCommand comm = null;
    int returnResult;

    try
    {
        comm = conn.CreateCommand();
        comm.CommandType = CommandType.Text;
        comm.CommandText = Query;
        comm.CommandTimeout = SQLTimeout;
            try
            {
                conn.Open();
                returnResult = comm.ExecuteNonQuery();
            }
            catch
            {
                conn.Close();
                throw new SqlException();
            }
    }
    catch (Exception ex)
    {
        throw new Exception(ex.Message.ToString());
    }
    finally
    {
        conn.Close(); // Always remember to close connection to database or else it would lead to memory leakage
    }

And don't even mention that what headache this code can cause to you in case you mess up or forget a single line of code from the above.

But do not worry, there is an easy solution.

Enters The EasySQL Class

Use EasySQL class library to execute any (or list of) SQL statement(s) without hassle.

Let me show you how you can write the aforementioned code using EasySQL Class as follows:

    EasySQL thisSQL = new EasySQL(SQLConnectionString);
    thisSQL.Execute(Query);

That's it. Nothing else. You don't have to worry about opening or closing database connections or worry about other small stuffs, so that you can devote more in developing your solution effectively rather than fighting to execute database queries.

Some Examples

Let's insert a new record of city in our CITIES table as follows:

    private void InsertCityRecord(string connectionString)
    {
      string query = "Insert Into [CITIES] (CityName, Country) VALUES('Kolkata', 'India')";

      EasySQL thisSQL = new EasySQL(connectionString);
      thisSQL.Execute(query);
    }

Or we can fetch user credentials from a form and use that to query our database as follows:

    private void runUserQuery()
    {
      // Fetch User input
      System.Windows.Controls.TextBox txtUserId = new System.Windows.Controls.TextBox();
      System.Windows.Controls.PasswordBox txtPwd = new System.Windows.Controls.PasswordBox();

      // Read config for connection string
      Configuration config = Configuration.WebConfigurationManager.OpenWebConfiguration(Null);
      ConnectionStringSettings connString = config.ConnectionStrings.ConnectionString[“MyConnString”];

      // Create sql credential
      SecureString pwd = txtPwd.SecurePassword;
      pwd.MakeReadOnly();
      SqlCredential cred = new SqlCredential(txtUserId.Text, pwd);

      // Execute using EasySQL
      EasySQL thisSQL = new EasySQL(connString);
      thisSQL.ExecuteProcedure(storedProcedureName, cred);
    }

Or we can also execute a list of queries as follows:

    private void runListOfQueries(List<string> queries, string connectionString)
    {
      // Initiate EasySQL
      EasySQL thisSQL = new EasySQL(connectionString);

      // Iterate over list of queries and execute one by one
      foreach(string query in queries)
      {
        thisSQL.Execute(query);
      }
    }
