Unable to run the command through Workflow

Hi,

I am unable to run the oracle quiery through Customization Workflow Code with normal roles and getting the below mentioned error, the same I can run successfully with TDAdmin role.

You do not have the required permissions to create the Command object. Contact your site administrator to make sure that the relevant Command settings are correct.:
====================
    set tdc = TDConnection
    strQuery = "SELECT * FROM BUG WHERE BG_BUG_ID="& refId
==> set Cmd = tdc.Command
    Cmd.CommandText = strQuery
====================

Please let us know what are the additions permssions needs to be enabled for the group to avoid this error and run the command.

OR

Let us know if there is any alternative method for permanent solultion for the project irrespective group.
