 Error Message:
 System.Data.OracleClient.OracleException: OCI-22053: overflow error

Here is the code: 

DataSet ds = new DataSet(); 
        try 
        { 
            this.OpenDBConnection(); 
            this.dbAdapter.ReturnProviderSpecificTypes = providerSpecificTypes; 
            this.dbAdapter.Fill(ds); 
        } 
        catch 
        { 
            throw; 
        } 
        finally 
        { 
            CloseDBConnection(); 
            this.cmd.Parameters.Clear(); 
        }
            return ds;

One of the selected column value is having a precision beyond the .Net's decimal type. The best way to resolve this issue is to ROUND your column values to a manageable prevision size. Normally I round them to 2 digits of decimal place as I would not need anymore than that, you may want to choose according to your need.

So in short, change your query so that all columns with a higher precision number to be rounded off to the number of decimals you need:

Example:

Select ROUND(final_price, 2) From <your table>

should address your problem.
