How i do that in code

public static int ExecuteNonQuery(string sql, DbParameter[] dbprmParameters = null)
    {
        return ExecuteNonQuery(sql, null, dbprmParameters);
    }
    public static int ExecuteNonQuery(string sql, IDbConnection dbConnection, DbParameter[] @params = null)
    {
        int RecordsCount = 0;

        lock (synObj)
        {

            if (cmd.CommandTimeout < 360)
                cmd.CommandTimeout = 360;
            if (sql == "") return 0;

            sql = AnalyizeBooleanFields(sql);
            cmd.CommandText = sql;

            cmd.Parameters.Clear();

            if (@params != null)
            {
                for (int i = 0; i < @params.Length; i++)
                {
                    cmd.Parameters.Add(@params[i]);
                }
            }
            if (dbConnection == null)
            {
                if (WithTransaction)
                    dbConnection = BeginTransaction();
                else
                    dbConnection = InitializeConnection();
            }
            if (dbConnection.State != ConnectionState.Open) dbConnection.Open();
            if (WithTransaction) cmd.Transaction = _transaction;
            cmd.Connection = dbConnection;
            RecordsCount = cmd.ExecuteNonQuery();
            if (!WithTransaction) dbConnection.Close();
        }
        return RecordsCount;
    }
public static string AnalyizeBooleanFields(string sql)
    {
        switch (DataAccess.Provider)
        {
            case Providers.Access2003:
            case Providers.Access2007:
                sql = sql.Replace("{{1}}", "True");
                sql = sql.Replace("{{0}}", "False");
                break;
            case Providers.SQLServer:
            case Providers.MySQL:
            case Providers.Oracle:
            default:
                sql = sql.Replace("{{1}}", "1");
                sql = sql.Replace("{{0}}", "0");
                break;
        }
        return sql;
    }

}
