I am developing an Excel VBA program that I want to connect to a remote Oracle 11g database, run a query, and return the data to Excel.
Connection strings and drivers are all OK as far as I know. (see below)
It was working perfectly for a while yesterday, connecting to db and returning with correct data. Then I saved and closed the workbook, opened it 20 minutes later (no changes made!) and when I ran the macro I got the following error:
Runtime error '-2147418113 (8000ffff)': Catastrophic failure
any ideas what could be causing the error?
Could it be something on the DB's side?
Thanks
Sub ExtractFromOracle(environment As String)
Dim cn As ADODB.connection
Dim recordSet As ADODB.recordSet
Set cn = CreateObject("ADODB.Connection")
Set recordSet = CreateObject("ADODB.recordset")
Dim SQLQuery As String
SQLQuery = "SELECT User_Id, Prof_Id FROM user_profile ORDER BY User_Id ASC"
Dim returnData As Variant
Dim returnedRowsCount As Integer
Dim connectionString As String
connectionString = ReturnConnectionString(environment)
cn.Open (connectionString) ------------> ERROR OCCURS HERE
Set recordSet = cn.Execute(SQLQuery)
returnData = Application.Transpose(recordSet.GetRows)
returnedRowsCount = UBound(returnData)
If Not SheetExist(environment) Then
CreateTab (environment)
End If
Worksheets(environment).Activate
ActiveSheet.Range("A1:B" & returnedRowsCount) = returnData

CONNECTION STRING :
"Provider=OraOLEDB.Oracle;Data Source=(DESCRIPTION=(CID=GTU_APP)(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=xxxxxxx)(PORT=xxxx)))(CONNECT_DATA=(SID=xxxxx)(SERVER=DEDICATED)));User Id=xxxxxx;Password=xxxxxxx;"
Can you try to access the ADODB as below
Dim strSQL As String, conStr as String
Dim cnn As New ADODB.Connection
Dim rs As New ADODB.Recordset
conStr = "Provider=OraOLEDB.Oracle;Data Source=(DESCRIPTION=(CID=GTU_APP)(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=xxxxxxx)(PORT=xxxx)))(CONNECT_DATA=(SID=xxxxx)(SERVER=DEDICATED)));User Id=xxxxxx;Password=xxxxxxx;"
Dim SQLQuery As String
SQLQuery = "SELECT User_Id, Prof_Id FROM user_profile ORDER BY User_Id ASC"
cnn.open conStr
rs.Open SQLQuery, cnn, adOpenStatic, adLockOptimistic, adCmdText
I fixed the error so I though I would update for anyone with the same issue who finds this thread.
It turns out that the 'Catastrophic Failure' error was due to my Oracle ODBC driver (oraOLEDB.oracle) becoming somehow corrupted, I couldn't even reinstall it properly, the error only occurred on my machine.
In the end I did a system restore to a point from before the issue and all was fixed. Not the most elegant solution but it worked.

I have a linked table in ms-access which is linked to a sql server table, and when I am trying to fetch the data in excel via VBA from ms-access linked table the error message "ODBC connection failed" showing.
Note:- I am manually successfully able to refresh ms-access linked table in ms-access, "peoplemain" is the name of linked table.
Note:- When I tried to fetch data from non linked table, it is running successfully.
Below code is working in Excel-32 bit version, but not working in excel-64 bit.
[code]
Sub FetchData()
Dim cn As ADODB.Connection
Dim rs As ADODB.Recordset
Dim conn As String
conn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=G:\Workflow Tools (Michael Cantor)\Tool For Fixing Bug From Michael Cantor\PI MDT Reconciliation Workflow Tool\SampleforPractice.accdb;"
Set cn = New ADODB.Connection
Set rs = New ADODB.Recordset
cn.Open conn
rs.Open "Select * from peoplemain", cn 'Error Line
Sheet1.Range("A1").CopyFromRecordset rs
rs.Close
Set rs = Nothing
cn.Close
Set cn = Nothing
End Sub
Thanks

I would try out setting a strSQL as a string like this (I had the same issue you did and when I made the change it worked for me):
Sub FetchData()
Dim cn As ADODB.Connection
Dim rs As ADODB.Recordset
Dim conn As String, strSQL AS String
conn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=G:\Workflow Tools (Michael Cantor)\Tool For Fixing Bug From Michael Cantor\PI MDT Reconciliation Workflow Tool\SampleforPractice.accdb;"
strSQL = "Select * from peoplemain"
Set cn = New ADODB.Connection
Set rs = New ADODB.Recordset
cn.Open conn
rs.Open strSQL , cn 'Error Line
Sheet1.Range("A1").CopyFromRecordset rs
rs.Close
Set rs = Nothing
cn.Close
Set cn = Nothing
End Sub
I need to get data from Access to excel vba, I use ADODB.
My problem is that although the database is relatively small and query results 30-40 records only, the process gets stuck either with the ".open" or with "copyfromrecordset" line and takes 40-50 secs to display the records.
This is my code.
I made some tests with different cursor types and locktypes with no result. The query is working executed directly from access and I have no issue when the connection points locally to my PC. I am on office 365. I referenced the activex data objects 2.8 library.
Sub loadTestDisplay2()
Dim myConnectiom As ADODB.Connection
Dim myRS As ADODB.Recordset
Const conStringNet As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=\\ourserver-f04\COE-Shared\Data Tool\Access\adsLoadTest.accdb; Persist Security Info=False;"
Dim sql As String
sql = "SELECT * FROM tblLoad where user is Null"
Set myConnection = New ADODB.Connection
Set myRS = New ADODB.Recordset
myConnection.ConnectionString = conStringNet
myConnection.Open
With myRS
.ActiveConnection = conStringNet
.Source = sql
.LockType = adLockReadOnly
.CursorType = adOpenForwardOnly
.Open
End With
Sheets.Add
Range("A2").CopyFromRecordset myRS
myRS.Close
myConnection.Close
End Sub
Let me start of by saying I am new to both this site as well as VBA so please bear with me. Thank you in advance for your help.
I have a VBA function that runs an existing query from Access. Some of the tables being queried are stored in an Oracle database that require a user specific password access. Right now, a sub that I wrote to automate a report calls this function 7 times and requires the user to input their Oracle password each time the function is called (it also stops the sub and gives an error message if they type in the password incorrectly which I see as a likely event if they need to do it 7 times). The code works but I would like to find a way to have the code ask for the password once and be done with it. All of the solutions I have found involve connecting to and querying Oracle directly which requires very complicated SQL coding that I am by no means capable of writing.
I am also having an issue where the columns show up in the excel sheet in a different order than they do in Access for some of the queries. This seems to be consistent so it isn't to big of a problem but I would like to know how to prevent this to prevent any future issues.
Here is the code for the function I am currently using. Any insight would be greatly appreciated!
Option Explicit
'Single Argument "qryName" as string. Runs access qry and copys recordset to active sheet.
Function AccessQueryPull(qryName As String)
'Declare variables
Dim rs As ADODB.Recordset
Dim cn As ADODB.Connection
'open the connection to the access database
Set cn = New ADODB.Connection
cn.Open "Provider=Microsoft.ACE.OLEDB.12.0; Data Source=filePath.accdb;"
'format the command to run the query
Dim cmd As New ADODB.Command
cmd.CommandType = adCmdStoredProc
cmd.CommandText = qryName
cmd.ActiveConnection = cn
'execute the query
Set rs = New ADODB.Recordset
Set rs = cmd.Execute()
'copy data to excel sheet
ActiveSheet.Cells(2, 1).CopyFromRecordset rs
'Cleanup
rs.Close
Set rs = Nothing
The reason you are prompted each time for Oracle credentials is that you create a fresh, new connection to MS Access each time the function is called.
Simply persist the MS Access connection by connecting once in the Sub that calls function and pass connection object as parameter. In this way, any connection error is caught in the parent routine. As for column order simply declare the columns in the needed order in SQL statement.
Sub RunQueries()
Dim rs As ADODB.Recordset
Dim cn As ADODB.Connection
'open the connection to the Access database
Set cn = New ADODB.Connection
cn.Open "Provider=Microsoft.ACE.OLEDB.12.0; Data Source=filePath.accdb;"
Call AccessQueryPull(cn, "SELECT Col1, Col2, Col3 FROM Qry1") ' AND OTHER 6 CALLS
cn.Close
Set cn = Nothing
End Sub
Function AccessQueryPull(accConn As ADODB.Connection, qryName As String)
'format the command to run the query
Dim cmd As New ADODB.Command
cmd.CommandType = adCmdStoredProc
cmd.CommandText = qryName
cmd.ActiveConnection = accConn
'execute the query
Set rs = New ADODB.Recordset
Set rs = cmd.Execute()
'copy data to excel sheet
ActiveSheet.Cells(2, 1).CopyFromRecordset rs
'Cleanup
rs.Close
Set rs = Nothing: Set cmd = Nothing
End Function
I am new to vba and I am using vba script to connect to database from excel and get the records. I have written the following script for that.I am getting a run time error '-2147467259(80004005)':Unspecified error.
How to resolve this error. See the error screen shot.
Sub Ora_Connection()
Dim con As ADODB.Connection
Dim rs As ADODB.Recordset
Dim query As String
Set con = New ADODB.Connection
Set rs = New ADODB.Recordset
'--- Replace below highlighted names with the corresponding values
strCon = "Driver={Microsoft ODBC for Oracle}; " & _
"CONNECTSTRING=(DESCRIPTION=" & _
"(ADDRESS=(PROTOCOL=TCP)" & _
"(HOST=host_name)(PORT=1521))" & _
"(CONNECT_DATA=(SERVICE_NAME=service_name))); uid=id; pwd=pw;"
'--- Open the above connection string.
con.Open (strCon)
'--- Now connection is open and you can use queries to execute them.
'--- It will be open till you close the connection
query = "select * from security.forms"
Set rs = con.Execute(query)
For i = 0 To rs.Fields.Count - 1
Sheet1.Cells(1, i + 1).Value = rs.Fields(i).Value
Next
con.Close
End Sub

Had you tried to use the open method of your RecordSet instance? Maybe it will give you another error that will be more helpful.
Dim connection As New ADODB.connection
Dim rst As New ADODB.Recordset
Dim query As String
connection.ConnectionString = CONNECTION_STRING
connection.Open
rst.Open query, connection, adOpenKeyset, adLockOptimistic
do while not rst.EOF
rst.MoveNext
loop
connection.Close
I had the exact same problem and it was tough to find an answer since most posts on this issue are unanswered.
I solved it by using another Oracle driver. Instead of Microsoft ODBC for Oracle try using the Oracle in OraClient11g_home1 driver. Hope this helps

I'm trying to run a query in an Access 2007 database from an Excel 2007 VBA script. The Access query has parameters called "Year" and "Month".
I'm trying to get the following code to work:
Sub RunMyQuery()
Dim cn As New ADODB.Connection
Dim rs As New ADODB.Recordset
Dim dbPath As String
Dim stQRY As String
Dim stCon As String
Dim cmd As New ADODB.Command
Dim prmYear As New ADODB.Parameter
Dim prmMonth As New ADODB.Parameter
dbPath = "<PATH_TO_MY_DB>"
stCon = "Provider=Microsoft.ACE.OLEDB.12.0;" _
& "Data Source=" & dbPath & ";"
cn.Open (stCon)
cn.CursorLocation = adUseClient
Set cmd.ActiveConnection = cn
Set prmYear = cmd.CreateParameter("Year", adNumeric, adParamInput, , 2011)
Set prmMonth = cmd.CreateParameter("Month", adNumeric, adParamInput, , 5)
cmd.Parameters.Append prmYear
cmd.Parameters.Append prmMonth
cmd.CommandText = "SELECT * FROM [Month_Totals]"
cmd.CommandType = adCmdTable
Set rs = cmd.Execute
Sheets("Sheet1").Range("A1").CopyFromRecordset rs
rs.Close
Set rs = Nothing
cn.Close
Set cn = Nothing
End Sub
When I run this, the code stops on "cmd.Execute" with
Run-time error '-214217900 (80040e14)':
Syntax error in FROM clause.
What am I getting wrong?
The command text seems simple enough to me. Am I missing something there?
Am I misusing the parameters functionality of ADODB.Command? I don't think that's the problem here, because I've tried running this same script with a non-parametrized query substituted for Month_Totals, and gotten the same error.
I believe The parameters are only for use when you are using a saved query in access. I would solve your problem by moving the parameters into the SQL statment.
Change
"SELECT * FROM [Month_Totals]"
to
"SELECT * FROM [Month_Totals] WHERE Year = 2011 AND Month = 5"
The reason that this is returning an error is that command type is set to adCmdtable, but the command does not reference a table, it references an SQL string, so:
cmd.CommandType = adCmdText
Next, in order to return specific data, you need to include a WHERE clause, with field names in the correct order for the parameters:
cmd.CommandText = "SELECT * FROM [Month_Totals] Where [Year]=? AND [Month]=?"
