Solved VBA Database.Execute("CreateTable...") - Table created in CurrentDB, not the specified DB (1 Viewer)

[jhg]

I have a front-end database that links tables from a couple of back-end databases (all MSACCESS/DAO). As part of a schema upgrade I executed the following:

    Dim dbLog As Database
    Set dbLog = ws.OpenDatabase(CurrentProject.path & "\" & "Log.accdb")
    ...
    dbLog.execute "create table ...."    ' A valid CREATE TABLE statement

Intending to follow up by creating a link to the table from the front-end to the backend.

This executed successfully, but the table was created in CurrentDB (the front-end) not the specified backend.

Is this expected? What am I missing?

you seem to be missing some code - ws is not declared, what is the code represented by ... and personally I would use dao.database rather than just database

Would using OpenCurrentDatabase work?

Just thinking out loud...

sample code:

    ' valid create table sql
    sql = "CREATE TABLE Employees (" & _
             "EmployeeID AUTOINCREMENT PRIMARY KEY, " & _
             "FirstName TEXT(50), " & _
             "LastName TEXT(50), " & _
             "HireDate DATETIME, " & _
             "Salary CURRENCY)"
    Dim dbLog As Database
    Set dbLog = DBEngine.OpenDatabase(CurrentProject.Path & "\Log.accdb")
    dbLog.Execute sql
    dbLog.Close

The following code snippet creates a temporary external database, and then creates two tables in it. Finally it creates links in the current database to the two tables:

    Dim dbs As DAO.Database, dbsTemp As DAO.Database, qdf As DAO.QueryDef, tdf As DAO.TableDef
    Dim varFld As Variant
    Dim n As Integer
    
    Set dbs = CurrentDb
    
    ' create temporary database in same folder as current database
    ' or return reference to database if already exists
    strTempDb = Left$(dbs.Name, Len(dbs.Name) - Len(Dir(dbs.Name))) & "BoMTemp.accdb"
    On Error Resume Next
    Set dbsTemp = CreateDatabase(strTempDb, dbLangGeneral)
    If Err <> 0 Then
        Set dbsTemp = OpenDatabase(strTempDb)
    End If
    On Error GoTo Err_Handler
    
    ' create BoM table in temporary database if doesn't exist
    strSQL = "CREATE TABLE BoM (MajorPartNum LONG NOT NULL, " & _
            "MinorPartNum LONG NOT NULL, Quantity LONG NOT NULL, " & _
            "CONSTRAINT MajorMinor PRIMARY KEY (MajorPartNum, MinorPartNum) )"
    On Error Resume Next
    dbsTemp.Execute (strSQL)
    On Error GoTo Err_Handler
    
    ' create BoM_Temp table in temporary database.
    ' note that this one has no constraint as it will be
    ' necessary to add duplicates of major/minor part number
    ' values in separate rows
    strSQL = "CREATE TABLE BoM_Temp (MajorPartNum LONG NOT NULL, " & _
            "MinorPartNum LONG NOT NULL, Quantity LONG NOT NULL)"
    dbsTemp.Execute (strSQL)
    
    ' check if link to BoM_Temp table exists and if not create link
    On Error Resume Next
    Set tdf = dbs.TableDefs("BoM_Temp")
    If Err <> 0 Then
        DoCmd.TransferDatabase acLink, "Microsoft Access", strTempDb, acTable, "BoM_Temp", "BoM_Temp"
    Else
        varFld = tdf.Fields(0)
        If Err <> 0 Then
            ' refresh link if current link invalid
            tdf.Connect = ";DATABASE=" & strTempDb
            tdf.RefreshLink
        End If
    End If
    Err.Clear
        
    ' check if link to BoM table exists and if not create link
    Set tdf = dbs.TableDefs("BoM")
    If Err <> 0 Then
        DoCmd.TransferDatabase acLink, "Microsoft Access", strTempDb, acTable, "BoM", "BoM"
    Else
        varFld = tdf.Fields(0)
        If Err <> 0 Then
            ' refresh link if current link invalid
            tdf.Connect = ";DATABASE=" & strTempDb
            tdf.RefreshLink
        End If
    End If
    Err.Clear

Well, in the famous words of Miss Emily Litella, "never mind".

I figured out my problem, and it was a result of revisiting very old code and forgetting what I intended when I wrote it.

Sorry for the meaningless noise.

jhg,
Since you marked this solved, would you share your code so others could see the solution.
Thanks.

Don't you just hate it when this happens.
