Selecting from a SQL Server 2005 with long column names ( 30 chars)

Question

Hi,
I was able to set up a db link from Oracle 11.2.0.1 to SQL Server 2005 using DG4ODBC.
My problem is that some column names in the Sql Server are longer than 30 chars and trying to select them gives me the ORA-00972: identifier is too long error.
If I omit these columns the select succeeds.
I know I can create a view in the sql server and query it instead of the original table, but I was wondering if there's a way to overcome it with sql.
My select looks like this:
select "good_column_name" from sometable@sqlserver_dblink -- this works
select "good_column_name","very_long_column_name>30 chars" from sometable@sqlserver_dblink -- ORA-00972Thanks

Answer 1

I tried creating a view with shorter column names but selecting from the view still returns an error.
create view v_Boards as (select [9650_BoardId] as BoardId, [9651_BoardType] as BoardType, [9652_HardwareVendor] as
HardwareVendor, [9653_BoardVersion] as BoardVersion, [9654_BoardName] as BoardName, [9655_BoardDescription] as BoardDescription,
[9656_SlotNumber] as SlotNumber, [9670_SegmentId] as SegmentId, [MasterID] as MasterID, [9657_BoardHostName] as BoardHostName,
[9658_BoardManagementUsername] as BoardManagementUsername, [9659_BoardManagementPassword] as BoardManagementPassword,
[9660_BoardManagementVirtualAddress] as BoardManagementVirtualAddress, [9661_BoardManagementTelnetLoginPrompt] as
MANAGEMENTTELNETLOGINPROMPT, [9662_BoardManagementTelnetPasswordPrompt] as MANAGEMENTTELNETPASSPROMPT,
[9663_BoardManagementTelnetCommandPrompt] as MANAGEMENTTELNETCOMMANDPROMPT FROM Boards)performing a select * from this view in sqlserver works and show the short column names
this is the error i'm getting for performing a select * from v_boards@sqlserver_dblink
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[Microsoft][SQL Native Client][SQL Server]Invalid column name 'BoardManagementTelnetLoginProm'. {42S22,NativeErr = 207}[Microsoft]
[SQL Native Client][SQL Server]Invalid column name 'BoardManagementTelnetPasswordP'. {42S22,NativeErr = 207}[Microsoft][SQL Native
Client][SQL Server]Invalid column name 'BoardManagementTelnetCommandPr'. {42S22,NativeErr = 207}[Microsoft][SQL Native Client][SQL
Server]Statement(s) could not be prepared. {42000,NativeErr = 8180}
ORA-02063: preceding 2 lines from sqlserver_dblinkI also tried replacing the * with specific column names but it fails on the columns that have a long name (it doesn't recognize the short names from the view)
what am I doing wrong?
