Re: [MS_AccessPros] Append table issue

 

Jim-


If anything on the form you're opening is bound to the table, it won't work.  Also, you should not use OpenQuery because that runs asynchronously - the first command might not be complete before the code attempts to run the second one.  Do it like this:

Private Sub Form_Open(Cancel As Integer)
Dim db As DAO.Database
'this set of code will
    'delete the records in the tblInProcessNewTask
    'alter the NewTaskID to reset to autonumber 1 each time
    'Append the records from the tasks table
    
    ' Point to this database
    Set db = CurrentDb

    'deletes all records in the tblInProcessNewTask table
    db.Execute "qryDeleteInProcessNewTask", dbFailOnError
        'tblInProcessNewTask

    ' Give the engine time to finish and free all locks
    dbEngine.Idle dbFreeLocks

    'alter the table to reset the autonumber for the NewTaskID field to 1 each time the form is opened.
    ' Set counter back to 1
    db.Execute "qryAlterInProcessNewTask", dbFailOnError
        'ALTER TABLE [Copy Of tblInProcessNewTask] ALTER COLUMN NewTaskID COUNTER (1, 1);
    
   'append the tblInProcessNewTask table with the in process records.
    db.Execute "qryAppendtblInProcessTasks", dbFailOnError
        'tblTasks           'main table with the tasks
        'tblTaskDetails     'related table to the tblTasks. the details for the tblTasks table
        
    Set db = Nothing

End Sub

John,

If I put the code behind a button on another form it works great. I probably will do it that way anyway. I just thought I would try it on the open event of the form. 

Thank You

John,

I am getting a run time error 3211
The database engine could not lock table tblInProcessNewTask because it is already in use by another person or process.

Below is my code and it is breaking on the query  named qryAlterInProcessNewTask which is the alter statement you suggested to use. I ran the queries individually and it worked, but if I put them in the vba procedure the code breaks. 

I must be missing something?/

Private Sub Form_Open(Cancel As Integer)
'this set of code will
    'delete the records in the tblInProcessNewTask
    'alter the NewTaskID to reset to autonumber 1 each time
    'Append the records from the tasks table
    
    DoCmd.SetWarnings False
    
    'deletes all records in the tblInProcessNewTask table
    DoCmd.OpenQuery "qryDeleteInProcessNewTask"
        'tblInProcessNewTask

    'alter the table to reset the autonumber for the NewTaskID field to 1 each time the form is opened.
    DoCmd.OpenQuery "qryAlterInProcessNewTask"
        'ALTER TABLE [Copy Of tblInProcessNewTask] ALTER COLUMN NewTaskID COUNTER (1, 1);
    
   'append the tblInProcessNewTask table with the in process records.
    DoCmd.OpenQuery "qryAppendtblInProcessTasks"
        'tblTasks           'main table with the tasks
        'tblTaskDetails     'related table to the tblTasks. the details for the tblTasks table
        
DoCmd.SetWarnings True


End Sub

OK.  That should work.  Be sure to substitute your actual table and column names.  Run the delete to empty the table, run the ALTER query, then run the INSERT query.

John,

I am emptying the table each time. I will give that a shot. Thank You

Jim-

If you're emptying the target table first, you can reset to 1 by executing an SQL command something like this:

ALTER TABLE MyTable ALTER COLUMN NameOfAutoNumberField COUNTER (1, 1);

That will reset your auto number field  to start back at 1 and increment by 1 - as long as the table is empty.

Hello all,

I have a table that I would like to append records from another table. The issueI am encountering is this.

How do I append the records into a table. I want to start at 1 every time.

I am able to append the records to the table but the new auto number are 4 at digits. Like 5299, 5300 etc.

Thank You 

Jim Wagner
