I am passing a query via Excel VBA OraOLEDB data provider to an Oracle 11.2g DB but its only returning partial results. The query has been validated in SQL Developer and works 100%. The OraOLEDB also works fine returning results for simple SELECT queries against the same Oracle 11.2g DB.

Does anyone possibly have any idea why the full set is not populating? Your help will be greatly appreciated

VBA (Sensitive info taken out of connection string)

Sub RunQuery()
    SrvrInfo = "Provider=OraOLEDB.Oracle;" & _
               "Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=hostaddress)(PORT=portnumber))(CONNECT_DATA=(SERVICE_NAME = servicename) (SERVER=DEDICATED)));User Id=user_id;Password=psswrd;"
    Set Connct= New ADODB.Connection
    With Connct
        .CursorLocation = adUseClient
        .Open SrvrInfo
        .CommandTimeout = 0
    Set RcrdSet = .Execute(SQLStmnt) ''See SQL query below
    End With
    aSpreadsheetRange.CopyFromRecordset RcrdSet 
    RcrdSet.Close
    Connct.Close
    Set RcrdSet= Nothing
    Set Connct= Nothing
End Sub

SQL Query (SQLStmnt variable in VBA above)

SELECT DISTINCT *
FROM (
SELECT 
  (CASE
    WHEN A.AGE < 15 THEN '1. < 15'
    WHEN A.AGE >= 15 AND A.AGE <= 24 THEN '2. 15 to 24'
    WHEN A.AGE >= 25 AND A.AGE <= 34 THEN '3. 25 to 34'
    WHEN A.AGE >= 35 AND A.AGE <= 44 THEN '4. 35 to 44'
    WHEN A.AGE >= 45 AND A.AGE <= 54 THEN '5. 45 to 54'
    WHEN A.AGE >= 55 AND A.AGE <= 64 THEN '6. 55 to 64'
    WHEN A.AGE >= 65 AND A.AGE <= 74 THEN '7. 65 to 74'
    WHEN A.AGE > 74 THEN '8. > 74'
  ELSE 'NO AGE'
  END) BUCKET,
     A.BONUS_MONTH
  Count(*) AGE_COUNT
FROM EMPLOYEE A
  GROUP BY 
  (CASE
    WHEN A.AGE < 15 THEN '1. < 15'
    WHEN A.AGE >= 15 AND A.AGE <= 24 THEN '2. 15 to 24'
    WHEN A.AGE >= 25 AND A.AGE <= 34 THEN '3. 25 to 34'
    WHEN A.AGE >= 35 AND A.AGE <= 44 THEN '4. 35 to 44'
    WHEN A.AGE >= 45 AND A.AGE <= 54 THEN '5. 45 to 54'
    WHEN A.AGE >= 55 AND A.AGE <= 64 THEN '6. 55 to 64'
    WHEN A.AGE >= 65 AND A.AGE <= 74 THEN '7. 65 to 74'
    WHEN A.AGE > 74 THEN '8. > 74'
  ELSE 'NO AGE'
  END)
) B
 PIVOT (SUM(AGE_COUNT) FOR BONUS_MONTH IN ('22/JUL/2016','22/AUG/2016'))
ORDER BY BUCKET
