Data From Excel Range To Existing Access Table
Greetings,
I have an excel workbook containing a range which has a single row of data ("rng_Data" in range C1:C4). I would like to be able to have some code that will allow me to push a button from Excel and have the range of data uploaded and appended to the bottom of an existing table in an existing Access database. Assume database is called "Database.mdb" and the table is called "Table1". The fields in the Access table have already been defined and match up with the number of data points in the range. Could someone help with some code that would transfer this data. Thanks. Jason |

This might be a help for getting data to and from Excel and Access: It
includes examples of using variables in SQL queries. http://www.bygsoftware.com/examples/sql.html Or you can get there from the "Excel with Access Databases" section on page: http://www.bygsoftware.com/examples/examples.htm It demonstrates how to use SQL in Excel's VBA to: * create a database, * create a table * insert records * select records, * update records, * delete records, * delete a table, * delete a database. DAO and ADO files available. You can also download the demonstration file called "excelsql.zip". The code is open and commented. -- Andy Wiggins FCCA www.BygSoftware.com Excel, Access and VBA Consultancy - "Jason" wrote in message ...

Thanks to all for the responses. I haven't had time to try out the code, but
it looks like I've gotten specific feedback and I believe I'll be able to make it work. Thanks again.

Hi,
While I can't say I understand all the code (I'm a novice), it works great. One quick follow up question.

How could I adjust the code below to make this work. I've tried various attempts but have been unsuccessful. Thanks.

What I am doing there is building a string to use as an SQL command to add a
line to the database. Let's say (for illustration) the values you want to add to the database are "1", "5", "22", "HELLO". The SQL command to do that would read: INSERT INTO [Table1] VALUES('1','5','22','HELLO') The order I give the values in corresponds to their resulting position in the database fields. In the code I am just splitting up the string and inserting the values from the specific cells. Range("C1").Value refers to the value that is in cell C1, etc.: SQLStr = "INSERT INTO [Table1] Values('" & Range(C1).Value & "','" ... Note how I also have to put the single quotes in there. This treats everything as a text value but that was the safe option (Access can usually do any necessary conversion when it adds the values to the table; it is really best though to send numbers as numbers, dates as dates, etc.) So - to get to the point: to use different values, e.g. A2:D2, just substitute the proper cell addresses into the statement: replace Range("C1").Value with Range("A2").Value, Range("C2").Value with Range("B2").Value, etc. -- - K Dales (long-winded answer but I hope informative) "Jason" wrote: Hi, While I can't say I understand all the code (I'm a novice), it works great.

Excellent! That helps a lot, I'm following you know. Just as a follow up,
is it possible then use the same logic, but instead of referencing individual cells, reference a named range? For example, could I take the named range "rng_Data", which referes to the range "A1:Z1", and substitute that in and have it still work? Thanks again.

Hi
your code works great and I have modified a little bit so make it once insert it to Access, it will then be deleted and looks like it is "moved" to Access. However, I have 2 problems he 1. the first field i have in the DB is an autonumber field, how can I handle it ? if I put an empty value, it will prompt error 2. the process seems a little slow, it seems using loop from row to row quite slow. thanks a lot Leung "michelxld" wrote: Hello I hope this help you Sub exportDatas_Excel_Access() 'Activate Microsoft ActiveX Data Objects x.x Library Dim Conn As New ADODB.Connection Dim rsT As New ADODB.Recordset Dim Cell As Range Dim i As Integer With Conn .Provider = "Microsoft.JET.OLEDB.4.0" .Open "C:\dataBase.mdb" End With With rsT .ActiveConnection = Conn .Open "Table1", LockType:=adLockOptimistic End With 'export range("C1:C4") in Access table With rsT .AddNew For i = 0 To 3 .Fields(i).Value = Cells(i + 1, 3) Next i .Update End With rsT.Close Conn.Close End Sub Regards , michel -- michelxld ------------------------------------------------------------------------ michelxld's Profile: http://www.excelforum.com/member.php...o&userid=17367 View this thread: http://www.excelforum.com/showthread...hreadid=392393 |

No, it is not so easy since you are building a string and you need to put the
actual values in - as if you are typing them. SQL (Structured Query Language) is a way of requesting data from a database that is independent of both the calling application and the database. That allows it to be very flexible and useful for sharing data across applications, but the problem is that it does not itself recognize any of the application's own features. What I mean in terms of your question is that SQL has no idea what an Excel range is, so you can't just say use Range("A1:Z1"). You need to actually specify the values. If this is something you will be using repeatedly, though, for a lot of different database tables and Excel ranges, the best thing would be to build your own function to convert a range (any arbitrary range) to the proper SQL "Values" list. E.g: Function BuildSQL(TableName as String, ValueRange as Range) as String Dim DataCell as Range, SQL as String, FirstCell as Boolean SQL = "INSERT INTO " & TableName & " Values(" FirstCell = True For Each DataCell in ValueRange If Not(FirstCell) Then SQL = SQL & "," SQL = SQL & "'" & DataCell.Text & "'" FirstCell = False Next DataCell SQL = SQL & ")" BuildSQL = SQL End Function I hope you still follow. I am just using the specified range to build the proper SQL statement, so the actual process of sending the command through VBA becomes simple and could be used over and over for many different tables/value ranges, in fact the whole thing as a piece of reusable code would be just this: Sub UploadData(TableName as String, ValueRange as Range) Dim MyCn As ADODB.Connection Dim SQLStr As String Set MyCn = New ADODB.Connection MyCn.Open "DRIVER={Microsoft Access Driver (*.mdb)}; " & _ "DBQ=C:\Database.mdb" MyCn.Execute BuildSQL(TableName, ValueRange) MyCn.Close Set MyCn = Nothing End Sub I haven't tested the code so hopefully I got it all right, but by now I think you understand enough to take the idea forward. It could, in fact, even be modified to use any database file... I will leave that to you! -- - K Dales "Jason" wrote: Excellent! That helps a lot, I'm following you know.

Let's say (for illustration) the values you want to add to the database are "1", "5", "22", "HELLO". The SQL command to do that would read: INSERT INTO [Table1] VALUES('1','5','22','HELLO') The order I give the values in corresponds to their resulting position in the database fields. In the code I am just splitting up the string and inserting the values from the specific cells. Range("C1").Value refers to the value that is in cell C1, etc.: SQLStr = "INSERT INTO [Table1] Values('" & Range(C1).Value & "','" ... Note how I also have to put the single quotes in there. This treats everything as a text value but that was the safe option (Access can usually do any necessary conversion when it adds the values to the table; it is really best though to send numbers as numbers, dates as dates, etc.) So - to get to the point: to use different values, e.g. A2:D2, just substitute the proper cell addresses into the statement: replace Range("C1").Value with Range("A2").Value, Range("C2").Value with Range("B2").Value, etc. -- - K Dales (long-winded answer but I hope informative) "Jason" wrote: Hi, While I can't say I understand all the code (I'm a novice), it works great. One quick follow up question. Suppose I were to change the range to be transferred in excel so that it was going across in a row instead of going down a column (i.e. range A2:D2). How could I adjust the code below to make this work. I've tried various attempts but have been unsuccessful. Thanks.

I would like to be able to have some code that will allow me to push a button from Excel and have the range of data uploaded and appended to the bottom of an existing table in an existing Access database. Assume database is called "Database.mdb" and the table is called "Table1". The fields in the Access table have already been defined and match up with the number of data points in the range. Could someone help with some code that would transfer this data. Thanks. Jason |
