Check for Primary Key

[BillyRogers]

Here a QA program that I have in Excel. the user clicks a button then this
program loops through all the mdb files in a folder on our network. Each
database has the same 12 tables but the databases all have different names.
The program does a query on each table---just a simple record cound and then
prints the database name, table name and record cound in the spreadsheet. it
works really well and has reduced a 6 hour job to about 20 minutes. there's
just one more thing I need to add. I need to check each table for a primary
key. If there is one I would like to add it to this line as a variable.

ActiveCell.FormulaR1C1 = DBName & ";" & table & ";" & _
rs.Fields("Count").Value

thanks,

Hi BillyRogers,

You can use the OpenSchema method of the Connection object to return a
resultset of the indexes a table has. It would be easier to manage if you
had a Connection object set up - then you could open the recordset and the
schema from that same connection.

Dim cn As ADODB.Connection
Dim rs2 As ADODB.Recordset

Set cn = New ADODB.Connection

With cn
.ConnectionString = "<your connection string here>"
.Open
End With

Set rs2 = cn.OpenSchema(adSchemaIndexes, _
Array(Empty, Empty, Empty, Empty, table)) '/ assumes table var
contains table name
rs.Find ("PRIMARY_KEY = True")

If Not (rs.EOF Or rs.BOF) Then
MsgBox "table contains primary key"
Else
MsgBox "no primary key"
End If

rs2.Close
Set rs2 = Nothing

To open your other Recordset, you can use the Execute method of the
Connection object. And you don't need to set rs to a new Recordset - that
will be done via the return value of the Execute method:

Set rs = cn.Execute("SELECT COUNT(*) AS [Count] FROM [" & table &
"]")

This way, you can reuse the connection. Hopefully this makes some sense and
works for you.

Thanks for the help. It was a little too complicated for me to integrage the
primary key check into the record count program so i built a separate program
to check the primary keys. Maybe now I'll work on integrating the two.

I just thought I'd post my solution in case anyone else has a similar problem.
