Export data from Excel to Access (ADO)

If you want to export data to an Access table from an Excel worksheet, the

macro example below shows how this can be done:

Sub ADOFromExcelToAccess()' exports data from the active worksheet to a table in an Access database' this procedure must be edited before useDim cn As ADODB.Connection, rs As ADODB.Recordset, r As Long ' connect to the Access database Set cn = New ADODB.Connection cn.Open "Provider=Microsoft.Jet.OLEDB.4.0; " & _ "Data Source=C:\FolderName\DataBaseName.mdb ;" ' open a recordset Set rs = New ADODB.Recordset rs.Open "TableName", cn, adOpenKeyset, adLockOp timistic, adCmdTable ' all records in a table r = 3 ' the start row in the worksheet Do While Len(Range("A" & r).Formula) > 0 ' repeat until first empty cell in column A With rs .AddNew ' create a new record ' add values to each field in the recor d .Fields("FieldName1") = Range("A" & r). Value .Fields("FieldName2") = Range("B" & r). Value .Fields("FieldNameN") = Range("C" & r). Value ' add more fields if necessary... .Update ' stores the new record End With r = r + 1 ' next row Loop rs.Close Set rs = Nothing cn.Close Set cn = NothingEnd Sub

The macro example assumes that your VBA project has added a reference to

the ADO object library.

You can do this from within the VBE by selecting the menu Tools, References

and selecting Microsoft ActiveX Data Objects x.x Object Library.

Use ADO if you can choose between ADO and DAO for data import or export.

Below is an extended example that shows how you can export data

from multiple workbooks:

Sub ExportMultipleFiles()Dim fn As Variant, f As IntegerDim cn As ADODB.Connection ' select one or more files fn = Application.GetOpenFilename("Excel-files,* .xls", _ 1, "Select One Or More Files To Open", , Tr ue) If TypeName(fn) = "Boolean" Then Exit Sub ' connect to the Access database Set cn = New ADODB.Connection On Error GoTo DisplayErrorMessage cn.Open "Provider=Microsoft.Jet.OLEDB.4.0; " & _ "Data Source=C:\FolderName\DataBaseName.mdb ;" On Error GoTo 0 If cn.State <> adStateOpen Then Exit Sub End If Application.ScreenUpdating = False ' repeat for each selected file For f = LBound(fn) To UBound(fn) Debug.Print "Selected file #" & f & ": " & fn(f) Application.StatusBar = "Exporting data fro m " & fn(f) & "..." ExportFromExcelToAccess cn, CStr(fn(f)) Application.StatusBar = False Next f Application.ScreenUpdating = True ' close the database connection cn.Close Set cn = Nothing MsgBox "The data export has finished!", vbInfor mation, ThisWorkbook.Name

Re: Delete previous data in the tableDepending on your SQL database type, something like this should work:

strSQL = "delete * from tablename" ' replace tablename

' or: strSQL = "truncate tablename" ' replace tablename

cn.Execute strSQL

The connection variable cn must be opened with write access and the user must have the

proper rights to delete data from the table.

Delette previous data in the tableWow, this is great.

This adds the data to an existing table, what if I want to replace the content of the table each

time I run the Macro (In other word, delette all the data in the table before I run this macro).

Thank you.


Re: Export from Excel to AccessYou can run SQL commands to create a new table, e.g. like this:

strSQL = "CREATE TABLE tablename ("

strSQL = strSQL & "LastName varchar, "

strSQL = strSQL & "FirstName varchar, "

strSQL = strSQL & "Address varchar, "

strSQL = strSQL & "Age int "

strSQL = strSQL & ")"

cn.Execute strSQL

You can learn more about SQL at W3 Schools.

Export from Excel to AccessThis works great for exporting to an existing table in Access. How do I modify this solution to

create a NEW table in Access from an Excel spreadsheet, complete with column headings?

Similar to the 'Transfer Spreadsheet' action in Access.

Thanks

Re: Great stuff. Used lots of information from here but. . .?You can use SQL statements to update a table with multiple records, e.g. like this:

insert into TableName1 select * from TableName2 where SomeField = 'dummy'

ADO also supports a batch update mode where you can update all record changes at once,

and rollback if the update fails. Using this method you will still have to add, change or delete

one record at the time in your code, before you finally submit the changes to the database.

You will find lots of examples if you search Google Groups for "ADO adLockBatchOptimistic"

Great stuff. Used lots of information from here but. . .?Most of your examples involve using data on a worksheet to update a database, and it would

seem that it is one record at a time. I've found another site ( XL-Dennis ) that showed me

how to import en masse from excel to Access. But now I'm wondering.

I'm attempting to get away from excel. So let's say I have an array of information ( existing

in memory only ) how can I use that array to update the database? Some arrays may be

quite huge so I'd like to not do this 1 record at a time.

Error while opening workbookI am using the code to export data from excel file to access database. When the control

comes to the following line in ExportFromExcelToAccess sub, it does not do anything, but

automatically goes to the beginning of macro.

Set wb = Workbooks.Open(strFullFileName, True, True)

Please let me know what could be wrong.
