SAS/ACCESS Oracle readbuff error

Hi All,

I have code that is pulling data from an Oracle database and uses readbuff option.

Code runs fine on our Linux server using SAS/ACCESS to Oracle.

On a Windows server using SAS/ACCESS to ODBC, it crashes with a traceback error.

Both servers are 9.3.

I haven't tested it much, cuz the Windows server admin doesn't like it when I do.   (Query is run by a stored process, I think it might actually cause a process to hang, but I don't have enough rights on the box to see).

Just wondering if anyone else has seen this?  It's a small table.

Seems like:

http://support.sas.com/kb/17/006.html

Example below, I get similar error using a libname with implicit pass-through.

6870      +proc sql;
6871      +  Connect to odbc(datasrc=... readbuff=250);
ODBC: AUTOCOMMIT is YES for connection 0
6872      +
6873      +  Select * from Connection to odbc
6874      +  (select * from Mytable)
6875      +  ;
 
ODBC_49: Prepared: on connection 0
select * from Mytable 
 
ODBC_50: Executed: on connection 0
Prepared statement ODBC_49

Yes, I know it says to contact tech support.  I would if I really needed a solution at this point (I can live with the defaults readbuff as it's a small table) , and if I could do more testing.  It's mostly Friday curiousity.

Re: SAS/ACCESS Oracle readbuff error

Hi, I have the same problem on Linux. See http://support.sas.com/kb/57/877.html. The readbuff does not seem to work well with the oracle client, so rather set the FetchBufferSize.
