Function to import a query as a Table

Posted on 2008-06-11

I have an Access Database that uses a snapshot query for ad hoc reports.  I do not want this user going into the Production Database to create new queries against this Query.  I know you can import a query as a Table.  How can I through a Function import a query as a Table from another database and replace the existing Table automatically.

Example the Table in my reporting database that comes from another database's query is named MainRecords_Snapshot.

The query in the database H:\Trucking\2007_SubmissionLog\Database\061008_Trucking_Submission_Log_NewChanges.mdb is named MainRecords_Snapshot

I run the function and it imports the query MainRecords_Snapshot from H:\Trucking\2007_SubmissionLog\Database\061008_Trucking_Submission_Log_NewChanges.mdb and replaces the Table MainRecords_Snapshot without prompts in my reporting database.

How can I do this?  Thanks

Why not create a base query (also must be set as a snapshot query) in the 'reporting' database that uses the snapshot query in the other database.

SELECT * FROM thesnapshotquery In "c:\myfolder\OtherDB.mdb"

The attached routine should point the way.
If your table layout is going to stay constant then it would probably be better to delete all records and append the new ones rather than removing and recreating the table as the example shows.
Sub ImportQueryAsTable()

    Const cLocalTable As String = "SupplierLookUp"

    Const cSourceDB As String = "'C:\Users\Miket\Documents\Technical\Northwind 2007.accdb'"

    Const cSourceQuery As String = "qrySuppliers"

    Dim strSQL As String

    strSQL = "SELECT * INTO " & cLocalTable & " FROM " & cSourceQuery & " IN " & cSourceDB

    ' Ignore any error thrown if table doesn't already exist

    On Error Resume Next

    CurrentDb.TableDefs.Delete cLocalTable

    ' switch back to default error handling

    On Error GoTo 0

    DoCmd.SetWarnings False

    DoCmd.RunSQL strSQL

    DoCmd.SetWarnings True

End Sub

Here is a try:
Remote database: C:\ManageRemote\db2.mdb
in db2, create a table t
field1      field2      field3
A      10      X
B      20      Y
C      30      Z

and a query q based on t

Select * from t;

The code snipped will create table q1t in local database populated with the result of q
Button Click event to run the code Snippet that follows.




Private Sub ManageRemoteDB_Click()
 

    Dim dfws As Workspace

    Dim rdb As Database 'remote database

    Dim rrs As Recordset 'remote record set

    Dim fld As Integer

    

    Set dfws = DBEngine.Workspaces(0)

    Set rdb = dfws.OpenDatabase("C:\ManageRemote\db2.mdb", True)

   'DoCmd.OpenForm db.Containers(2)("f")

   Set rrs = rdb.OpenRecordset(rdb.QueryDefs("q").Name) ' this is the query in rdb

   'steps to create table is here - keep going

   Dim flds As String

   flds = ""

    For fld = 0 To rrs.Fields.Count - 1

        If fld = 0 Then flds = "'1' As [" + rrs.Fields(fld).Name + "],"

        If fld = rrs.Fields.Count - 1 Then flds = flds + "'1' As [" + rrs.Fields(fld).Name + "]": Exit For

        If fld > 0 Then flds = flds + "'1' As [" + rrs.Fields(fld).Name + "],"

    Next fld

    flds = "SELECT " + flds + " INTO q1t"

    

    DoCmd.SetWarnings False

    DoCmd.RunSQL flds

    DoCmd.RunSQL "Delete * from q1t"

    With rrs

        Do Until rrs.EOF

            For fld = 0 To rrs.Fields.Count - 1

                If fld = 0 Then flds = """" & Nz(rrs.Fields(fld), "0") & ""","

                If fld = rrs.Fields.Count - 1 Then flds = flds + """" & Nz(rrs.Fields(fld), "0") & """": Exit For

                If fld > 0 Then flds = flds + """" & Nz(rrs.Fields(fld), "0") & ""","

            Next fld

            DoCmd.RunSQL "INSERT INTO q1t  VALUES (" & flds & ")"

           rrs.MoveNext

        Loop

    End With

    DoCmd.SetWarnings True

    rrs.Close

    rdb.Close

    Set rrs = Nothing

    Set rdb = Nothing

End Sub
