I think that you are on to something there Don.

I just tried accessing a table from our Oracle server, which I do know
exists, but for which I do not have access permissions.

Using the following query in the Oracle Instant Client:

  select table_name from all_tables;

I can get a list of all tables on the server, which includes a table
called INCOMPATIBLE_USER_AGENTS, for which I do not have access
permissions.

When attempting to query the table in the Instant Client I get:

SQL> select * from INCOMPATIBLE_USER_AGENTS;
select * from INCOMPATIBLE_USER_AGENTS
              *
ERROR at line 1:
ORA-00942: table or view does not exist


When running the same query from R using RODBC I get:

> sqlQuery(db, "select * from INCOMPATIBLE_USER_AGENTS")
[1] "[RODBC] ERROR: Could not SQLExecDirect"                                
[2] "42S02 942 [Oracle][ODBC][Ora]ORA-00942: table or view does not exist\n"


So it looks like permission issues may be possible here.  Eric,
definitely confirm with your SysAdmins that you have appropriate
permissions.

HTH,

Marc
