Run query connected to another database in VBA Access - sql

I am trying to run saved query inside VBA Access. That query is connected to another database and looks like that:
SELECT * FROM TABLE IN 'C:\USERS\Another_database.accdb'
This query is saved as "My_query" inside first Access database. VBA code looks like this:
Function My_function()
Set rst = CurrentDb.OpenRecordset("My_query", dbOpenDynaset)
End Function
When I try to run it i got an error:
Run-time error '3219'
Any ideas why? It works for normal queries (without IN 'C:\USERS\Another_database.accdb' part.

The most efficient way to get data from another Access database on an ongoing basis is with Linked Tables.
Click External Data on the ribbon, then New Data Source → From Database → Access
Browse to the source database, and make sure you choose Link to the data source by creating a linked table
Select one or more tables that you want to link
[
The linked tables will be created and you will be able to query the linked tables as if they were local to the current database.
More Information:

Maybe you need to define a Recordset first or try to remove the quotation marks you have in the example? The following example works fine:
Dim rs as Recordset
Set rs = CurrentDb.OpenRecordset("SELECT Field FROM Table IN 'here goes your path'")
Now you have an Array rs() in which you can loop.

ODBC linked database with / in field name

I'm trying to link an ODBC database - which I have no control on - in MS Access 2007 using a Machine Data Source - I don't know if that's relevant, from what I got this means that the access is set only on this computer -.
When I follow the wizard I can select the table but when the time comes to link it I get the error message:
The database engine can't find 'WTD.DATAPOINT_5/1000'. Make sure it is a valid parameter or alias name, that it doesn't include characters or punctuation, and that the name isn't too long
I think that the problem is that one of the field is named WTD.DATAPOINT_5/1000 and that Access interprets /as a symbol of its own.
The thing is that I don't even need the data stored in this column. Right now I don't know which way to go.
Find a way to tell Access that the / is part of the field name. (Highly improbable)
Retrieve only some fields from the table using built-in Access functions.
Set the connection manually using vba and retrieving only some of the fiels. If this is the way to go I would like some pointers as I have no idea where to start.
Solution number 2: use a passthrough SQL query.
Everything is explained in this tutorial.
Solution number 3: I tried to connect directly in VBA. The code bellow works like a charm for other tables but I still get an error for the table containing the problematic field.
Dim ConnectionStr As String
ConnectionStr = "ODBC;Driver={Oracle in OraHome92};Dbq=BLA1;Uid=BLA2;Pwd=BLA3;"
DoCmd.TransferDatabase acImport, "ODBC Database", ConnectionStr, acTable, "MyTable", "NewTable"

Import sql query on ODBC table in MS Access 2007

Using MS Access 2007 I would like to retrieve only part of an ODBC table.
I can import the whole table in Access but I don't need all of it and it would be a waste of space and performance to store the whole table when I only need certain columns.
In Excel I wrote a SQL query that let me retrieve only the part I'm interested in. What I'd like to know is: is it possible to import only the result of a SQL query in Access or do I have to retrieve the whole table and then run the query on it?
Is it possible using built-in Access module or should I turn to VBA?
Edit: Basically I would like to run the ODBC data connection below (currently used in Excel) in Access.
Connection string:
DSN=BLA1;
UID=BLA2;
DBQ=BLA3;
PWD=BLA4;
DBA=W;
APA=T;
EXC=F;
FEN=T;
QTO=T;
FRC=10;
FDL=10;
LOB=T;
RST=T;
GDE=F;
FRL=F;
BAM=IfAllSuccessful;
MTS=F;
MDI=F;
CSR=F;
FWC=F;
PFC=10;
TLO=0;
Command string:
SELECT *
FROM TEST TEST
WHERE (TEST.DATE_STAMP=?)
When I try to link the database I get the error The database engine can't find 'WTD.DATAPOINT_5/1000'. Make sure it is a valid parameter or alias name, that it doesn't include characters or punctuation, and that the name isn't too long. but when I use the Excel database connection I get no error and everything is updated.
You don't need to import the whole table. You could link to the ODBC table and then run a make-table query against that linked table to copy in only the rows and columns that you need.

(VB / ACCESS / CR) Filter VB Crystal Report based on Access Form

Before I get to the question, here is an overview of what is going on.
Access
A form that has a ComboBox that selects a JobId
Crystal Reports
A Report that calls info from several tables, all based on the JobID
VB
A Form (Using the Crystal Reports Plug-In) that shows the Report outside of the Crystal Reports Designer app.
My Problem
I need the report displayed in VB to be filtered to the job chosen in the Access ComboBox.
Update
I have my Database linked to VS2012, and that works fine without any issues. I can pull info from a Table easily. What I need to do is link the ComboBox from an Access Form to VS2012 to filter the Report.
I hope that makes my question clearer.
Update 2
I was able to figure out how to create a SELECT Query based on the value of my ComboBox inside of Access, so I should be able to use that to access the Value I am looking for, however I still need to know how to use that value as a filter for CR...
One possible solution would be to create a saved Select Query in Access that replicates the query in CR, and name that query [JobReport_base]. Then, create another saved Select Query in Access and name it [JobReport_current]. Add some code to your Access form that updates the .SQL property of the [JobReport_current] query to return just the records for the selected [JobId], something like
Dim qdf As DAO.QueryDef
Set qdf = CurrentDb.QueryDefs("JobReport_current")
qdf.SQL = "SELECT * FROM JobReport_base WHERE JobId = " & cbxJobId
Set qdf = Nothing
Then update your Crystal Report to pull the data from the [JobReport_current] query instead of the individual tables.
Multiple solutions. In your case, the simplest ones are the following:
There is this 'sqlQueryString' property of the report that you could update by directly updating the string.
You could also add a parameter (let's call it 'PAR_yourCombobox') to the report. When accessing the report in your VB code, just set the value of your parameter to the value on the screen. as far as I remember, it should look like:
yourReport.parameterFields(i).addCurrentValue yourForm.controls("yourCombobox").value

What could be SQL Query of a data source that is a spreadsheet, to be returned to a seperate spreadsheet? Including UDFs in the query?

I currently have a data source of a large table, sitting in workbook1. From workbook2, which is currently empty, I wish to set up a DSN connection to workbook1, so that I can query it from workbook 2.
In the SQL query result, I wish to display extra columns which are calculated using User-Defined VBA functions, the arguments of which will be other fields from the data source.
Example:
Workbook1 is Field1, F2, F3 and F4. I wish to query this and display all records, but additionally I wish to have F5=UDF(F3,F4).
I have been advised already that the solution to this is:
SELECT UDF(F3,F4) as F5
FROM \SourceWorkBookLocation\SourceWorkBook
IN ACCESS:
The problem I am having in access is not at the top of my list right now, relates to data types and trying to determine if a number in a string is <25. But the main problem is in MS Query:
IN EXCEL/MS QUERY:
The function is just not recognized; "undefined function"
I am not sure how to get it to see the function? My end goal here is to build a front end in excel, and have vba querying appropriately using user input variables passed to the queries. The querying will be done on a separately updated workbook.
Any ideas on how to get MS Query to see my UDF and accept what I am doing? Could it be a driver issue? There are a range of excel drivers to choose from.
Thanks
Looking at the info you have provided, you have tried to use two Excel workbooks as tables to query using Excel VBA UDF. Now I assume you are going to use these workbooks as your tables but in MS Access.
All most all databases is able to read standard SQL. See the thing is that each database is able to handle functions writting in their own space. In your case please write your UDF in Access VBA. Then try to execute to the same.
This is a common issue sometimes people do face, either tyring to access MS Access UDFs from Excel or vise versa. In a nutshell, when you're running MS Access, queries can call back into VBA. But when you're going through ODBC or ADO, the JET engine doesn't have the whole VBA model to draw on because it's simply not running.
You could try to do something like this:
Dim objExcl As Object
Set objExcl = CreateObject("Excel.Application")
objExcl.OpenCurrentDatabase "ExcelFileName/Path"
objExcl.Run ("UDFName")
objExcl.CloseCurrentDatabase
Set objExcl = Nothing
Frankly I prefer moving the UDF in to Acces..

MS Access query with dynamic from statements

Ok this is vexing me. I have a query I created with an in statement in the from clause. What I am looking to do is have a global variable populate that from statement. Example
Select *
Form query1 in <Global Variable filename>
What is going on is I link to a file that has hundreds of linked table and queries in it. My database only has a few select queries and link table to different database. I did not want to re-build all the queries and linked table is my database. The issue is the file with all the links changes name once a month. I just want to read a text file with the current name of the database in it so I do not have to keep changing my queries every time the database name changes. Also this has to a query since I have other queries using the externally linked query.
I have one suggestion, but its pretty kludgy.
Rewrite the query on the fly with VBA call
Private Sub update_qtest()
Dim db As Database
Dim qd As QueryDef
Set db = CurrentDb
Set qd = db.QueryDefs("qtest")
qd.SQL = "SELECT * from query1 in " & g_file_name
End Sub
As I said, it's kludgy, but I don't think there's a way to pass the from clause as a parameter.
Another way to do this would be to just use the same file name each month so you wouldn't have to change anything in your Access app at all. You could easily code copying the file to the standard name over top of the previous copy (you'd have to delete it before copying, of course), which would retain the history.
