Error with query in OracleDataAdapter

Question

I have the following query:
<code>SELECT FI.FACILITY_OID, FI.FACILITY_NUMBER , FI.FACILITY_NAME , FI.TYPE_CODE ,
TC.DESCRIPTION AS TYPE_CODE_DESCRIPTION, FI.SUB_CATEGORY_CODE , SCC.NAME AS CATEGORY_CODE_DESCRIPTION,
FI.HEADWALL_TYPE, FI.EXTERNAL_LENGTH , FI.EXTERNAL_WIDTH ,
FI.INTERNAL_LENGTH , FI.INTERNAL_WIDTH , FI.FRONT_BARRICADED ,
FI.INTERNAL_VOLUME , FI.FRAG_CONTAINED , FI.PORT_FACIL_EXCEPTION ,
FI.REINFORCED_OPENINGS , FI.SINGLE_AIRCRAFT
FROM FACILITY_INFO FI INNER JOIN TYPE_CODE TC ON FI.TYPE_CODE = TC.TYPE_CODE
INNER JOIN SUB_CATEGORY_CODE SCC ON FI.SUB_CATEGORY_CODE = SCC.SUB_CATEGORY_CODE
WHERE FI.TYPE_CODE IN ('ECM', 'AGM', 'REM', 'OSM', 'EOL')
AND FI.INSTALLATION_ID = 1000 </code>
The query works fine when I run it in the SQL command window of the OracleXE database web management tool, but when I try to use the query in the OracleDataAdapter.FillSchema method, I get the error:
System.InvalidOperationException occurred
Message="Syntax Error: Expecting ',' or 'WHERE' (etc.) after table alias."
Source="System.Data.OracleClient"
If I skip the FillSchema method and just call Adapter.Fill it works just fine - the query runs and the data is returned. So I would just drop the call to Adapter.FillSchema, but I suspect somebody put that call there for a reason and it will be missed it I just take it out. :)
Anybody got any insight as to what's going on?

Perhaps removing the ANSI syntax would be beneficial?
