How to Docmd.CopyObject-- Pick last table with last date and time

ca1358,

The problem is that your current naming convention does not sort in date order across years.  If you change the way you create sNow to:

sNow = Format(Date, " yyyymmdd") & "_" & Format(Time, "hhnn")

the versions will sort alphabetically in chronological order through time. Then you can use

sPrefix = "YourTableBaseName"
sCrit = "Name Like '" & sPrefix & " ########_####' AND Type=1"
sLatestTable = DMax("Name", "MSysObjects", stCrit)

to get the latest saved table name.
Write back if you need to keep the current table names.

HTH,

I need to keep the table name without the date.

Thank you.

I'm sorry, I know you want the tables in the morning database to have no date in their names, but I meant to say, are you committed to having the backup versions in:

TableName mmddyy_hhnn

or can you change the standard to

TableName mmddyyyy_hhnn?

Sorry, meant in the last line:
TableName yyyymmdd_hhnn ?

I have not  got this to work.

What is the syntax of CopyObject statement?


DoCmd.CopyObject "\\XXXXXXXXX\XXXXXXXX\XXXXXXXX\XXXXXXX\XXXXXXXXXX\ExportDB.mdb", Table2", acTable, " Table2 090810_0808"

Here is what I have

Option Compare Database
Option Explicit

Private Sub Command0_Click()
SendBackupTables
End Sub

Function SendBackupTables()

Dim strDestinationMDB As String
Dim dbsData As DAO.Database
Dim sPrefix
Dim sCrit
Dim sLatestTable

strDestinationMDB = "\\XXXXXXXXXXX\XXXXXX\XXXXX\ExportDB.mdb"
Set dbsData = DBEngine.OpenDatabase(strDestinationMDB, _
False, False, ";pwd=bigblue")

 DoCmd.SetWarnings False

sPrefix = "Table1"
sCrit = "Name Like '" & sPrefix & " ########_####' AND Type=1"
sLatestTable = DMax("Name", "MSysObjects", sCrit)


DoCmd.CopyObject "\\XXXXXXXXXXX\XXXXXX\XXXXX\ExportDB.mdb", "Table1", acTable, "sLatestTable"

MsgBox "Tables have been Exported", vbExclamation + vbOKOnly, "Tables Exported"

End Function

Select allOpen in new window

Keeping your current table-naming system, you can use a query to create a date/time field that sorts the like-named tables.

Write a query named qryLatestTable with the SQL:

SELECT TOP 1 MSysObjects.Name, DateSerial(Mid([Name],Len([Name])-6,2), Mid([Name], Len([Name])-10,2), Mid([Name], Len([Name])-8,2)) + TimeSerial(Mid([Name], Len([Name])-3,2), Mid([Name], Len([Name])-1,2),0) AS TableDate
FROM MSysObjects
WHERE (((MSysObjects.Name) Like 'Table2 ######_####') AND ((MSysObjects.Type)=1))
ORDER BY DateSerial(Mid([Name],Len([Name])-6,2),Mid([Name],Len([Name])-10,2),Mid([Name],Len([Name])-8,2))+TimeSerial(Mid([Name],Len([Name])-3,2),Mid([Name],Len([Name])-1,2),0) DESC;

Then, replace line 43 in your code above with:

DoCmd.CopyObject "\\XX\X\X\X\X\ExportDB.mdb", "Table2", acTable, DLookup("Name", "qryLatestTable")


If you change the format of sNow to yyyymmdd_hhnn, you can skip the query and use

DoCmd.CopyObject "\\XX\X\X\X\X\ExportDB.mdb", "Table2", acTable, DMax("[Name]", "MSysObjects", "Type=1 AND [Name] Like 'Table2 ########_####')

HTH,

pT72

Remove the quotes around sLatestTable in ID:33649925, line 23.

The syntax is:
DoCmd.CopyObject DestinationDatabase, NewName, SourceObjectType, SourceObjectName

Can you go through the code step-by-step and make sure the Dlookup is finding the table?

You can also try :

Docmd.TransferDatabase acExport, "Microsoft Access", DatabaseName, acTable, Source, Destination

as shown on
http://accessblog.net/2006/04/how-to-export-objects-to-secured.html

This seams to work.

I changed the formatting to copy over to this.

TableName yyyymmdd_hhnn

Please look at it and tell me if you think it looks ok.

Option Compare Database
Option Explicit
Private Sub cmdSendTables_Click()
SendBackupTables
End Sub

Function SendBackupTables()

Dim strDestinationMDB As String
Dim dbsData As DAO.Database

strDestinationMDB = "\\XXXXXXX\XXXXXXXXXX\XXXX\XXXXXX\XXXXX\ExportDB.mdb"
Set dbsData = DBEngine.OpenDatabase(strDestinationMDB, _
False, False, ";pwd=XXXXXX")

    DoCmd.SetWarnings False

DoCmd.CopyObject "\\XXXXXXX\XXXXXXXXXX\XXXX\XXXXXX\XXXXX\ExportDB.mdb", "YourTableNameWithoutDate", acTable, DMax("[Name]", "MSysObjects", "Type=1 AND [Name] Like ' YourTableNameWithoutDate ########_####'")

MsgBox "Tables have been Exported", vbExclamation + vbOKOnly, "Tables Exported"

End Function

Select allOpen in new window

Thank you for all your work!!!

Oh, and add these lines after the MsgBox:

dbsData.Close
Set dbsData = Nothing

to close and de-reference the database you previously opened with a password. The code will run without it, but it's better practice to close anything you opened and Set any objects to Nothing.
