Using ODBC In VBA (Excel)


I have a MySQL database and a corresponding ODBC data source.
I have added the ODBC add-in (XLODBC.XLA) to Excel (2000) application.
Now, I want to connect to database and perform a simple query.

How to start? What type objects must I declare?
A simple short example code should be wonderful.

Thanks,
Ovidiu

Talking To Excel Via ODBC
Hi!

I am making a small application to send emails to multiple recipients. For now the program should import recipients from an Excel spreadsheet, but in the future multiple formats could be supported. I have already done the import by talking to an instance of an Excel spreadsheet (dim app as Excel.Application, etc)
However, if multiple formats of data are to be supported in the future, I should ideally use ODBC to connect to the workbook. This way I could talk to a DBF or flatfile in the same fashion without changing too much code. I am able to make a connection to an Excel workbook via DataEnvironment (via UDLs), but I do not know how to access the data via ADO. Is it possible? If yes, I would appreciate even the tiniest tip.

Thanks a lot in advance,
Stanislav

Excel RDO And ODBC Connections
With all the hassle of using excel as an object within other applications. I was wondering about about the other ways to pull data out of Excel. I've been told that you can use RDO or even ODBC to create a recordset from Excel. How does this work? What are the advantages and disadvantages?

 

ODBC Excel Driver
I am using the following code to open a connection to an Excel workbook but whenever I run the code it opens the workbook that I am querying?!

Set oConn = New ADODB.Connection
oConn.Open _
"Driver={Microsoft Excel Driver (*.xls)};" & _
"DriverId=790;" & _
"Dbq=" & sFile & ";" & _
"DefaultDir=c: emp"

Set oRs = New ADODB.Recordset

strSQL = "Select * FROM Wherever$;"

oRs.Open strSQL, oConn, adOpenStatic, , adCmdText

What I want to do is query the Excel workbook without it opening. How do I achieve this?

ODBC Import To Excel Via VBA Code
I want to get data from another computer through an ODBC connection in VBA code into an Excel spreadsheet. Does anyone know the Provider to use for an ODBC connection in the following code, and do I need an ODBC reference library to use it?

ALSO: I am able to import the data manually through the Excel toolbar now by doing: Data Import External Data Import Data supplying connection name signing onto a connection of format nnn.nnn.nnn.nnn.nnn and specifying where to put the data in my worksheet.

Am I on the right track below to get at this kind of a ODBC connection? Any examples of the Data Source line to use out there?

Dim adoBTC As ADODB.Connection
Dim BTRec As ADODB.Recordset
Set adoBTC = New ADODB.Connection

*** Need this line ***
adoBTC.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" _
& "Data Source=C:AccessMyDB.mdb""
***
adoBTC.Open ' open the connection
strTableName = "ODBC Table"
End If
Set BTRec = New ADODB.Recordset
BTRec.Open strTableName, adoBTC, adOpenKeyset,
adLockOptimistic, adCmdTable
.
.
code to sequentially read & filter the records into an excel worksheet.

How Do I Open The ODBC Administrator W/ Excel VBA ?
I used to use XLODBC's SQLOpen to cause the ODBC Adminstrator window to open. Everything I read tells me to use ADO.

I need VBA code that opens the ODBC Adminstrator so I can build have it automatically build the Connection String.

ODBC Update Of MSQuery In Excel
I have finally got the first phase of my Excel application running great to retrieve data from Quickbooks in an MSQuery using the QODBC driver (which makes a Quickbook file look like a standard ODBC database). Now I am ready to go to the next phase and start updating Quickbooks from my application. I can't seem to find any relevant examples of updating an ODBC database from Excel. Most of the examples I have examined seem to assume that you have a recordset from an ADO/OLEDB connection. However, when I examine the attributes of my Worksheet.QueryTable, it says "Not a DAO Recordset datasource" for the Recordset property.

For now, at least, I just want to update fields in one record at a time upon user request (i.e., a button click or menu command), especially since I have to select a subset of the fields which are updatable. The Quickbooks SDK interface upon which QODBC is built does not support update of many critical fields that can be retrieved, in order to maintain integrity of its database. What is the best way to go about this. It has been many years since I did any database updating, and at that time it was just simple straightforward SQL in a DB2 database. Any help to get me started in the right direction would be greatly appreciated.

Reading An Excel Worksheet Using ODBC From VB.NET
How do I access an Excel Workbook from VB.NET using the ODBC driver? I want
to read Excel data into a DataGrid control on a web-page. Although ODBC
says it can connect to Excel, it then asks me to design the query in SQL,
and tells me no matter what I specify, that it's wrong.

How do you specify data from Excel via ODBC?
And is it possible to OLE DB as well?

Thanks!

ADO/OLEDB With Excel ODBC Driver - Help!
I am attempting to read the contents of an Excel worksheet into a VB6 program using ADO, OLEDB and the Excel ODBC driver.

The Excel driver has 'intelligence' built in, so it determines the best data type to represent each column in the worksheet. This does not work as I need it to!

I know there are parameters to control the DAO/JET version of the driver, but I can't find any for the ODBC driver.

The connection string I'm using is this:

ConnString = "Provider=MSDASQL;Driver={Microsoft Excel Driver (*.xls)};DBQ=" & ExcelPath & ";MaxScanRows=0;"

I use MaxScanRows=0 to try and get the driver to assess the whole worksheet. However, when processing the worksheet I still get NULL values in certain fields, when I am expecting numbers or text.

Are there any parameters I can pass which control how the ODB driver processes the worksheet, in terms of scanning rows, column data types, default conversion, etc?

Scanning MSDN has not helped - as usual the examples are too simplistic, or do not cover what I need.

Any help would be appreciated.

Cheers - Jiminy

Excel ODBC Driver Missing Data Out
I am using an odbc for excel driver to read the contents of an excel file trhough vb into a sql database but some of the data in one column is not all coming through. The column at fault holds the telex number, in some rows this data is right justified (text) or left justified (number) and only the right justified rows are showing any data, the left ones show the column for that row as being empty.

The simplest change I know would be to get the source spreadsheet altered so that the column was all formated into text but I am not sure this is possible, any suggestions on why this is failing. We are using mdac 2.6

cheers

Problem Writing Excel Formulas Via ODBC
I have a C++ program writing records to an Excel spreadsheet via ODBC/SQL. The text and number values are inserted ok. I am also trying to write a formula (eg. =HYPERLINK("http://www.abc.com", "Click here for the abc site") ) into the sheet.

The problem: the formulas are displayed as formulas - they do not calculate. If I edit the formula (changing nothing but simply pressing return to re-enter the original value) then the formula is calculated. In the example above, the hyperlink is displayed as a link.

The same problem exists for any formula (even something as simple as =2+2).

Does anyone know why the formulas are not calculated ? Pressing F9, Shift-F9, Crtl-Alt-F9, or calculating the worksheet with VBA don't have any effect.

I can't believe that formulas have to be manually entered or edited before they become active. If I am missing something please let me know. Thanks in advance.

Problems Converting From MS ODBC To Oracle ODBC
Im on Oracle client 8.1.7.4, and Im trying to update some apps to be compatible with Oracle 9i.
I was told Microsoft ODBC for Oracle was not supported on 9i.

So, Im trying to convert over to the Oracle ODBC, but now I am getting errors on all my PLSQL calls, and I dont understand why.

Some of the error messages I am getting:

When I run the following:
Set adoParam = adoCommand.CreateParameter("ERRDESC", adVarChar, adParamOutput, 200)
'Set some other params
adoCommand.Execute nRecordsEffected, , adExecuteNoRecords
I get this error:
[Oracle][ODBC]Restricted data type attribute violation.

This worked before, when using the Microsoft ODBC. What is different?



Another quick Q:
I also tried using the Oracle OLEDB. This connected fine when using ADO, but when I tried to connect with RDO it failed. Is RDO compatible with the Oracle OLEDB?

Thx!
Dave

How would I go about something like a login system to a hosted MySQL that I own? I've gotten it to connect, but in my code I am trying to figure out after running this query (SELECT * FROM db.mytable WHERE username='test' AND password = md5('test2'), but I want to fetch the amount rows from that query, and I am used to PHP's mysql_num_rows function. So, any help would be greatly appreciated.

ODBC Help
When I create a new System Data Source Name for SQL server it will go through complete process of creating the DSN but when I go to see the newly created DSN, it is not in the list. I know it is there because if I want to re-create it with the same DSN name, I get the message “the DSN exist do you want to over write it”?

Creating a DSN for Microsoft Access, it does not even go pass asking the driver type?

I have re-installed win 2000 SP2, and re-installed MDAC 2.7 still could not solve the proble.

If you have seen this problem and you know the solution, please inform me. It will be appreciated.

Thank you for your time and concerns.

I have a Crystal Report 4.5 problem.....

I have a basic ODBC report i have created but can not get it to print/export/preview etc from the VB enviroment.....

It works Ok from the Crystal Reports Enviroment.....

CReport.ReportFileName = App.Path & "game.rpt"
CReport.Destination = crptToWindow
CReport.SQLQuery = "SELECT * FROM GameData.`GameData` WHERE GameData.`Round` = " & cmbRound.Text
CReport.DiscardSavedData = True
CReport.PrintReport

Round = type "String"

I have set the ServerType, ServerName etc during Design Time in Crystal Reports.....

I am wondering if i need any other statements calling the control?
Do i need to Log on to the Server in VB even though i have done it in Crystal Reports?

Am i going about this all wrong?

I have attatched the Report if needed.....

Believe me i have gone through all the help system, i must be missing something...

ODBC Vs. ADO
This may be a dumb quetion but...
what is the difference between an ADO connection and ODBC connection....I thought the ODBC just automatically did all the stuff for u(setting up the connection with the simplicity of clicks) whereas ADO u have to specify a driver, server, DB, etc...dont they use all the same driver files???

ADO To ODBC
Hi,

I am kind of being challenged by another developer at work regarding an issue to connect SQL Server in a VB6 application. So I just want to make sure I am correct before I further discuss with him.

I have a VB6 application developed since 2003 and it's working fine in all PCs at different remote sites. Now our company has a new office and the users in there can't access the system due to connection failure to SQL Server.

The developer in the new office told me that the network configuration in there is quite weird that he sometimes experienced SQL Server connection problem with his applications too. One way he used to resolve the problem is to change the connection method to ODBC. My problem is, if my application is using ADO, it is not that easy to change to ODBC because many methods, properties, and database components are for ADO only so simply changing the connection to ODBC will not work. Am I correct?

That developer told me there is no difference.

ODBC API In VB6?
I'm trying to write an installation program in VB6, and I need it to automatically create an ODBC connection to a SQL Server database. The only code I've been able to find on the 'net thus far is VB2 and 3 code, using things that apparently aren't available in VB6. Could someone help me with this? Here's my code, I can't get it to not give me an error.


Code:
Private Declare Function SQLConfigDataSource Lib "ODBCCP32.DLL" _
(ByVal hWndParent As Long, ByVal fRequest As Long, ByVal lpszDriver _
As String, ByVal lpszAttributes As String) As Long
'ODBC Creation Procedure
Public Sub RegisterODBCDatabase(dsn As String, driver As String, _
silent As Integer, attributes As String)

Dim ret As Integer
Dim temp As String
Dim spot As Integer
Dim att As String

attributes = Replace(attributes, Chr(13), Chr(0)) ' Replace Carriage returns with nulls

attributes = attributes & Chr(0) & Chr(0) ' End of attribute section.
temp = "DSN=" & dsn & Chr(0) & attributes

ret = SQLConfigDataSource(frmMain.HWND, ODBC_ADD_DSN, driver, temp)

' ret is equal to 1 on success and 0 if there is an error.
If ret <> 1 Then
MsgBox "SQLConfigDataSource call failed"
Else
MsgBox " SQLConfigDataSource call succeeded!"
End If
Exit Sub
End Sub
I've cut a few things out of the function (IP addresses, etc) for security purposes, so if it doesn't compile as-is, (I do realize it never creates a ODBC connection) I missed something when I was cutting, and chopped it.

Thanks in advance,

DB Odbc/ado
Does anybody know of a good odbc tutorial? I just need the basics. I was programming in vb with access databases a few months ago, but I forgot exactly what I did. I remember I had to like import an object something like:

Provider = "Ole.Jet.MicrosoftDatabase..."

And then I used sql queries and loops to move the information about. Any help is appreciated.

Edit: It might have been ADO and not ODBC, honestly I'm not sure.

Using ODBC
I am a complete newbie when it comes to data access and VB. At work here we use a pervasive SQL database and I was interested in using sql commands to query the database. I was told the easiest way to do this was by using ODBC. I have no idea what it is or how I would go about using. I do know sql syntax and all that good stuff. Could someone point me in the direction of a tutorial or something for use of ODBC by newbies? Or if you could help me a little I would appreciate it.

Thanks in advance.
