Question

Code that populates an access database field with the date/time of when the script last ran...

Asked by: luke311

Experts,

Is it possible to run a script and have a chunk of code that will poplulate an access database field with the date and time the script was executed?

If so... any suggestions on how to go about this would be greatly appreciated.

Thanks,

Luke

Just to clarify, are you looking to do this from a vbscript (.vbs file)? If so,here is a basic example that can be added to your script:


set conn= CreateObject("ADODB.Connection")
conn.Provider="Microsoft.Jet.OLEDB.4.0"
conn.Open "c:\MyDatabase.mdb"  ' change to name of your database

set rs=CreateObject("ADODB.recordset")
rs.CursorLocation=3 ' adUseClient
rs.CursorType=1     ' adOpenKeyset
rs.LockType=3         ' adLockOptimistic
rs.Open "Select * from MyTable", conn  ' change MyTable to name of your Table

' add new record
rs.AddNew
rs.Fields("field1").Value = Now  ' Change field1 to name of your field
rs.Update

' cleanup
rs.close
conn.Close
Set rs = Nothing
Set conn = Nothing

You mentioned script, so I'll assume you mean script and will answer accordingly (no strongly-typed Dims, for example).

The 'chunk' of code you describe might look something like this:

Dim cnn
Set cnn = CreateObject("ADODB.Connection")
cnn.Open = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=AccessDbPathAndFileName"
cnn.Execute "INSERT INTO SomeTable ( SomeField ) VALUES (#" & Now() & "#)"
cnn.Close
Set cnn = Nothing

Of course, you'd have to change the third line of code to reflect your Access database location and name and the fourth line of code to reflect the actual table and field names.

Hope this helps.

Yes, i am talking about a vbs script.

Thanks for the suggestions.  I'll play around with this, thanks for the help.

I also should add, there's a tiny typo in my code above (though in testing it doesn't seem to affect execution):
the third line should be
     cnn.Open "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=AccessDbPathAndFileName"

NO EQUAL SIGN between Open and "Provider...".  Sorry for the fat-finger.

OK so i have been working on the suggestions i got. in particular the one i got from pique tech.

I am including the code that i have been working with...  Could someone check the logic?  When i run it in the script i don't get any error but i'm not getting any data in the database.  Any suggestions to get me back on the right path would be greatly appreciated!

Here's the code:

strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
    & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")

Set colItems = objWMIService.ExecQuery("Select * from Win32_LocalTime")

Dim cnn
Set cnn = CreateObject("ADODB.Connection")
cnn.Open  "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=\\sam\d$\inetpub\wwwroot\luke\scans\database\iava.mdb"

For Each objItem in colItems
cnn.Execute "INSERT INTO dbo_ComputerMasterList (Search_Date) VALUES (#" & objItem.Month & "/" & objItem.Day & "/" & objItem.Year &"#)"
cnn.Execute "INSERT INTO dbo_ComputerMasterList (Search_Date) VALUES (#" & objItem.Hour & ":" & objItem.Minute & ":" & objItem.Second &"#)"
Next

cnn.Close
Set cnn = Nothing

I have tested the code you posted above, and it works just as expected (I get a perfectly-formatted string to execute against the properly-defined ADO Connection object).  So my next trouble-shooting suggestion is this:  rule out connectivity problems to the Access database by trying this as your Connection command:
     "INSERT INTO dbo_ComputerMasterList (Search_Date) VALUES (#9/29/2005#)"
with the value hard-coded.
if that doesn't work, open up the Access database directly, go to Queries->New->Design View->Close->SQL View and paste in that same string and see if the database will permit you to execute it.  If not, you should get some reasonably clear Access error message about why Access is unhappy with your attempt to insert data.  If you can execute it directly in the Access db, then their may be some security or permissions issues to consider.

Is that database in any way secured, or is it possible that anyone else would have it open at the same time as you in Exclusive mode?

I also note that the name of your Access table is very suggestive of a linked SQL server table.  If you're trying to insert into a linked table in an Access database, you'll have to consider the security context of the SQL server too.  In fact, I've never tried that -- I never figured out how I would provide SQL credentials to the Access database via ADO connection object.  So if that's the case, it might be easier to insert your data directly into the SQL server, though that will require some security configuration of the SQL server to permit your process to access it.

Thanks for the help pique tech.  I'll play around with that and see what i can come up with...  It is a  linked table so i'll look into the sql security config. and see what happens.  I appreciate your help.

 

by: luke311Posted on 2005-09-30 at 07:12:44ID: 14992403

Since i'm trying to insert directly into sql...  I'm having troubles figuring out what the proper security configuration should be...  Any suggestions you may have would be greatly appreciated.

The way I've done this in the past is to create a SQL logon on the SQL server, then configure my ADO connection with the logon ID and password.  That SQL logon must have write priveleges to the table you're trying to insert the data into.  (I've never tried a "trusted connection" approach because in my situation, the scripts run under an automated process that doesn't have a windows/network logon.  I'm not saying it can't be done, but I've never figured out how and don't know how I'd approach it.)

Opening the connection then would look like this:

     cnn.Open "Provider=SQLOLEDB;Data Source=TheSQLServerName;Initial Catalog=TheDatabaseName;UserId=TheSQLUserID;Password=TheSQLUserPassword"

of course putting the right values in for TheSQLServerName, TheDatabaseName, TheSQLUserID, TheSQLUserPassword
