I am working on an access database, and want to create a button that will open up a file explorer, where a user can look for a file, and when they click it, the path will be saved.
To put the database in perspective, my company works with many vendors, and each of them sends us prices in different formats (pdf, excel, word, etc.). So I want the users of the database to be able to look up a vendor, and easily have access to their prices (some of which change quarterly, so it is easier to just change the file instead of putting the prices in the database and updating it there).
Any help would be greatly appreciated.
Try this....
Sub sheet_dialogue_box()
Dim intChoice As Integer
Dim strPath As String
Application.FileDialog(msoFileDialogOpen).AllowMultiSelect = False
intChoice = Application.FileDialog(msoFileDialogOpen).Show
If intChoice <> 0 Then
strPath = Application.FileDialog(msoFileDialogOpen).SelectedItems(1)
Application.Workbooks.Open (strPath)
End If
End Sub

I have views that my users often only need to check for one particular person at a time. To do this, they do the following in Excel 365 desktop:
Open a blank workbook
Click on the 'Data' ribbon
Click 'Get Data'
Click 'From Database'
Click 'From SQL Server Database'
Fill in the 'Server' and 'Database' fields
In the advanced options, type SELECT * FROM [VEIWS].[VIEW_NAME] WHERE [EMP.ID] = '123456'
Click OK.
This is tedious for my users. If they want to check another person, they have to repeat the entire process. I'd love for them to just be able to use the query editor and change the only line that matters (see step 7), but they've only got the Select and View Definitions permission, which causes the query editor to complain. I'm afraid that I don't have the specific error message, but it's certainly to do with permissions.
Is there a less-repetitive way to do this from Excel? In an ideal world, I'd just make a sheet that lets them type in the EMP.ID immediately and then fetches the info. I think that it can be done with macros, but they're never my first choice and seem to require that I save passwords in the workbook.
Note that my users can't just fetch the entire view and filter it down in Excel. There are too many rows for Excel to handle.
I have no idea what permissions error you’re hitting, but people commonly use Windows credentials instead of Database credentials and get stuck. Power Query saves credentials on each computer, so you are relying on them signing in correctly. The first time someone connects to a data source, they are prompted for credentials. The default is for a Windows credential, and likely they need to enter a Database credential. If they get this wrong, they have to go into the Data Source settings to edit or clear the credential to fix it.
As far as changing the value in the SQL, you can easily have a parameter in Excel that changes the EMP.ID value in your query. Ken Puls has a nice write up on the process here. Reply back if you’re stuck.
You could use a SSAS Cube with a PivotTable in Excel with a filter on EMP.ID.
I guess it is not possible to change the query in Excel without Power Query Editor and I think it was not intended to do so (regulary).
If it does not need to be Excel you cloud just use SSMS or any similar alternative.
did you try to Un-tick the box that says "Require user approval for new native database queries" ?
you can set the ID as a parameter as suggested above... check my sample file for running an SQL query with a parameter. Sample File
also you can automatically refresh the worksheet with something like :
Private Sub Worksheet_Change(ByVal Target As Range)
If Intersect(Target, Me.Range("datachange")) Is Nothing Then Exit Sub
Application.EnableEvents = False 'to prevent endless loop
'Application.Goto Reference:="Tum_Santiyelerin_Satinalinan_Malzemeleri"
Range("EMP_ID").ListObject.QueryTable.Refresh BackgroundQuery:=False
ActiveWorkbook.RefreshAll
Application.EnableEvents = True
End Sub
I had a similar requirement in the past. My solution was to use the QueryTables object to send a query to the database using user-supplied data from a cell on the worksheet. It does use a macro, but I didn't have to save the credentials in the workbook.
This solution requires an ODBC driver for SQL Server.
(I seem to recall that I also had to check the references in Visual Basic - in toolbar Tools>References - but it was a while ago and I don't remember the exact details.)
Add the vb code below to a new workbook. Then if you enter the [EMP.ID] value in cell A1 of Sheet1 and run the macro 'ReadData', it will pull out the records and display them starting in cell A3.
Save the workbook as macro-enabled .xlsm and it can be shared with your users. (You could also assign the macro to a keyboard shortcut or command button to speed things up for your users.)
(This approach attempts to connect to the database using a trusted connection, i.e. using windows log-in credentials. I also use another database which requires separate credentials. I have another example below for that scenario.)
The vb code for the macro is below. Check the connection string that it has the correct driver and server IP address etc. and that the query string it reading the correct table.
Sub ReadData()
''' read database using filter supplied in cell A1
Dim ConnectionString As String
Dim QueryString As String
' Create connection string using credentials
ConnectionString = "ODBC; DRIVER={SQL Server}; SERVER=XX.XX.X.XXX; DATABASE=XXXXXXXXX; SCHEMA=dbo; REGION=yes;"
' Create query string to read data using value of cell A1
QueryString = "SELECT * FROM [VEIWS].[VIEW_NAME] WHERE [EMP.ID] = '" & Range("Sheet1!A1").Value & "'"
' The lines below can be un-commented if you get errors - it might help with debugging
'Range("Sheet1!C1").Value = ConnectionString
'Range("Sheet1!C2").Value = QueryString
' This code sends the query to the database and drops the results starting at cell A3
With Sheets("Sheet1").QueryTables.Add(Connection:=ConnectionString, _
Destination:=Range("Sheet1!A3"), Sql:=QueryString)
.RefreshStyle = xlOverwriteCells ' this stops excel from inserting new columns when the query is re-run
.Refresh False
End With
' Remove connections to avoid wasting memory
For Each con In Sheets("Sheet1").QueryTables
con.Delete
Next
End Sub
When the database requires different credentials
For this I created a user form to get the username and password, which I then incorporated into the connection string.
The steps I followed were:
In a new workbook, go to Visual Basic and create a new user form. Re-name it LoginForm
Create 2 text boxes on the form, named Username and Password. (You can also add labels and set the PasswordChar to '*' to make it look more like a login window.)
Create a command button ('OK' or 'Done'). Right click on it and select View Code. Enter the line Me.Hide in the code window so it looks like:
Private Sub CommandButton1_Click()
Me.Hide
End Sub
The vb code for the macro changes to :
Sub ReadData()
''' read database using filter supplied in cell A1
Dim ConnectionString As String
Dim QueryString As String
' First time you run, need to show form to get credentials
If LoginForm.Username = "" Or LoginForm.Password = "" Then LoginForm.Show
' Create connection string using credentials
ConnectionString = "ODBC; DRIVER={SQL Server}; SERVER=XX.XX.X.XXX; DATABASE=XXXXXXXXX; SCHEMA=dbo; REGION=yes; uid=" _
& LoginForm.Username & "; pwd=" & LoginForm.Password
' Create query string to read data
QueryString = "SELECT * FROM [VEIWS].[VIEW_NAME] WHERE [EMP.ID] = '" & Range("Sheet1!A1").Value & "'"
' The lines below can be un-commented if you get errors - it might help with debugging
'Range("Sheet1!C1").Value = ConnectionString
'Range("Sheet1!C2").Value = QueryString
' This code sends the query to the database and drops the results starting at cell A3
With Sheets("Sheet1").QueryTables.Add(Connection:=ConnectionString, _
Destination:=Range("Sheet1!A3"), Sql:=QueryString)
.RefreshStyle = xlOverwriteCells ' this stops excel from inserting new columns when the query is re-run
.Refresh False
End With
' Remove connections to avoid wasting memory
For Each con In Sheets("Sheet1").QueryTables
con.Delete
Next
End Sub
Now, the first time the user runs the code, it will prompt them for username and password, but for the rest of their session it will keep using these values. They will not be saved when the workbook is closed. (If the macro hits an error they will probably be asked for credentials again next time it is run).
Hopefully this helps you. I did this work some time ago and I may have forgotten if there were any other set-up requirements needed.
I cant find anything online to help.
I want to create a table if it doesnt already exist, or populate a listbox with what is stored in said table if it DOES exist. All I have so far is the populate and create table subroutines, but have no idea how to check the database so far.
Thank you
Checking if an MSAccess DATABASE exists or not is pretty simple because it is just a single file. So using File.Exists is enough
Suppose that your MDB file is
Dim accessFilePath = "D:\temp\myDatabase.mdb"
If File.Exists(accessFilePath) Then
... file exists
End if
Of course getting the content of the file (in terms of TABLES and QUERY) is a different thing and requires to open the connection and get the SCHEMA informations
Dim cnnString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & accessFilePath
Using con = new OleDbConnection(cnnString)
con.Open()
Dim schema = con.GetSchema("Tables")
For Each row As DataRow in schema.Rows
Console.WriteLine(row.Field(Of String)("TABLE_NAME"))
Next
End Using
See how GetSchema works and what are its possible parameters and results
Is there a way to append records from excel in to my main table allowing the user to still add additional fields in to the same table? I already have a search box that will populate the form with the record you search for. So, ideally, the user types search criteria for one (unique) field, then about half of the fields should auto-populate so the user can manually enter the remaining half and save the updated record.
This needs to be done multiple times per day, so im trying to find the easiest/most reliable way possible!
Also, data-validation is not good in the excel source (another reason we are building this database). So the imported data is not 100% consistent (all entered manually by people)!
You can do this via VBA. It will be a little time consuming, but if you're intending this to be a long term solution (I hope not?) then you'll need to do it that way. Here is a little snippet for you to start with:
'Open Excel and grab data
Dim oExcel As Object
Dim oBook As Object
Dim oSheet As Object
Set oExcel = CreateObject("Excel.Application")
Set oSheet = oExcel.Open("PathOfWorksheet").Worksheets("WorksheetNumber")
msgbox oSheet.cells(1, 1).Value
oExcel.Quit
Combine that with CurrentDB.Execute "INSERT INTO tblMyTable (Field1, Field2) VALUES (val1,val2)"
I am looking to load a .txt file into a VBA array (in an access VBA), manipulate it there, and then paste the manipulated array into an access table. I will loop this macro then through round about 500 .txt files and populate the database with years of data.
I have done it before using Excel in this way:Populating the sheet for 1 .txt file, manipulating the data, loading into the database, clearing the sheet, and loading the next txt file and loop till all files have been processed. However, this takes years and it becomes obvious that Excel is not really needed, since everything is stored in Access anyway.
Since then, I have tried to figure out how to do it in access straight away, without using excel, but I have been struggling. I found some nice code on this board here:
Load csv file into a VBA array rather than Excel Sheet
and tried to amend it so it would work for me. Especially The_Barman's Answer at the bottom seems simple and very interesting.
I am new to arrays, VBA, SQL, basically everything, so maybe there is some big mistake I am making here that is easy to resolve. See my code below:
Sub LoadCSVtoArray()
Dim strfile As String
Dim strcon As String
Dim cn As ADODB.Connection
Dim rs As Recordset
Dim rsARR() As Variant
Set cn = New ADODB.Connection
strcon = "Provider=Microsoft.JET.OLEDB.4.0;Data Source=" & "\\filename.txt" &
";Extended Properties=""text;HDR=Yes;FMT=Delimited"";"
cn.Open strcon
strSQL = "SELECT * filename.txt;"
Set rs = cn.Execute(strSQL)
rsARR = WorksheetFunction.Transpose(rs.GetRows)
rs.Close
Set cn = Nothing
[a1].Resize(UBound(rsARR), UBound(Application.Transpose(rsARR))) = rsARR
End Sub
I dont even know if the bottom part of the code works, because an error message pops up that the file is not found. The interesting thing is, if I debug and copy the value of strcon into windows "run", it opens the correct file. So I guess the path is correct? Can I even open a .txt file through an ADODB connection? Right now I am a bit confused if this is possible and if it is the best solution.
Some more background regarding the text files I am trying to save into the array:
-They are output from another program, so it is always the same structure and very oreganized
it comes in this format:
Column a Column b ....
data 1 data 1
data 2 Data 2
...
and so on.
If possible, I would like to retain this structure, and even safe it as a table with the first row as column headers.
The Data Source is the folder path containing the file and the file is the table (SELECT * FROM ..). Replace "\\filename.txt" in strcon with the folder path.

I need a good way to convert input data from 900 spreadsheets into a format suitable for upload to a relational database (XML or flat file/s). The spreadsheets are multi-sheet, multi-line Excel 2007 each one consisting of 7 forms (so its definitely not a simple grid). There will be no formula data to get, just text, dates, integer data.
The 900 spreadsheets are all in the same format.
I will need some kind of scripted solution.
I'm expecting I should be able to do this with excel macros (and I expect a fancy scriptable editor could do it too) or possibly SSIS.
Can someone tell me how you would approach this if it was yours to do?
Can anyone give a link to some technical info on a good way to do this?
I'm new to excel macros but used to programming and scripting languages, sql, others.
Why? We're using spreadsheet forms as an interim solution and I then need to get the data into the database.
You probably want to write data out to a plain text file. Use the CreateTextFile method of FileSystemObject. Documentation here:
http://msdn.microsoft.com/en-us/library/aa265018(v=vs.60).aspx
There are many examples on the web of how to iterate over worksheets, capture the data and then use WriteLine method.
Sub ExampleTextFile()
Dim fso as Object
Dim oFile as Object
Dim fullExport as String
'Script that will capture data from worksheet belongs here _
' use the fullExport string variable to hold this data, for now we will _
' just create a dummy string for illustration purposes
fullExport = "Example string contents that will be inserted in to my text file!"
Set fso = CreateObject("Scripting.FileSystemObject")
'In the next line, replace "C:\filename.txt" with the specified file you want to create
set oFile = fso.CreateTextFile("C:\filename.txt", Overwrite:=True, unicode:=True)
oFile.WriteLine(fullExport) '<-- inserts the captured string to your new TXT file
oFile.Close
Set fso = Nothing
Set oFile = Nothing
End Sub
If you have character encoding issues (I recently ran in to a problem with UTF16LE vs. UTF8 encoding, you will need to use the ADODB.Stream object, but that will require a different method of writing the file.
