Adding/Updating Records in Access with Excel
 

Hi Everyone-

I have found some code that has helped me add records to an Access (2003)
table. I am having difficulty though finding a way to tell the VBA to either
Update/Append or add a new record when I click the button. My Unique field
in excel is in col. A and is tied to the Access field name "Project_Name".
If the record, based on the ID, already exists, I would like for it to simply
update all of the records. If the record is new, based on the project ID, I
would like for it to add a new row in the access DB. Below is the code that
I have so far...

DB name: Test Project DB.mdb
Table Name: ProjectDataCollection
Unique ID Location in Excel: Column A ("Project_Name")

Private Sub CommandButton1_Click()

' exports data from the active worksheet to a table in an Access database
' this procedure must be edited before use
Dim 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=\\HSG\Files\HSG Resources\PM Task Force 2006\Tools -
Design Versions\Test Project DB.mdb;"
' open a recordset
Set rs = New ADODB.Recordset
rs.Open "ProjectDataCollection", cn, adOpenKeyset, adLockOptimistic,
adCmdTable
' all records in a table
r = 2 ' the start row in the worksheet
Do While Len(Range("A" & r).Formula) 0
' repeat until first empty cell in column A
.AddNew ' create a new record
' add values to each field in the record
.Fields("Project_Name") = Range("A" & r).Value
.Fields("Estimated_Start") = Range("B" & r).Value
.Fields("Estimated_Launch_Fielding_Date") = Range("C" & r).Value
.Fields("Estimated_Close_Fielding_Date") = Range("D" & r).Value
.Fields("Estimated_Finish_Date") = Range("E" & 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 = Nothing

End Sub

Thank you for your help!!!!

You need a line: With rs
befo .Add New

Will this check to see if the record is already there?

No. You need to search the records if you want to update existing
ones. The records having a primary key would make it easier to find a
match. The steps would be as follows. For each row in Excel search the
Access table. If a match is found, update the record. If a match is
not found, add a new record.

Try this, changing references to suit.
