Answer 1

the below snippet works fine for me on SqlServer:

public DataSet executeProcedure(String procudureName, params SqlParameter[] sqlParameters)
{
    return executeSqlCommand(procudureName, CommandType.StoredProcedure, sqlParameters);
}
public DataSet executeSql(String commandText, params SqlParameter[] sqlParameters)
{
    return executeSqlCommand(commandText, CommandType.Text, sqlParameters);
}
public DataSet executeSqlCommand(String commandText, CommandType Commandtype, params SqlParameter[] sqlParameters)
{
    DataSet myset = new DataSet();
    using (var command = Database.GetDbConnection().CreateCommand())
    {
        command.CommandText = commandText;
        command.CommandType = Commandtype;
        foreach (var _kv in sqlParameters)
        {
            DbParameter _dbpara = command.CreateParameter();
            _dbpara.ParameterName = _kv.ParameterName;
            _dbpara.Value = _kv.Value;
            command.Parameters.Add(_dbpara);
        }
        Database.OpenConnection();
        DbDataAdapter adapter = DbProviderFactories.GetFactory(Database.GetDbConnection()).CreateDataAdapter();
        adapter.SelectCommand = command;
        adapter.Fill(myset);
    }
    return myset;
}

the DbDataAdapter instance can be retrieved from DbProviderFactories class.

DbDataAdapter adapter = DbProviderFactories.GetFactory(Database.GetDbConnection()).CreateDataAdapter();
