Hi:
In VB I have the user select the Access database, and SQL database dynamically. In other parts in VB, I have created a table in both Access and SQL using the command object. Now, I need to get the data from SQL table to Access table. Notice these are the tables I have created in VB so they have the same sturcture.  I need the most efficient code example to bulkcopy the table from SQL to Access. NOT ROW BY ROW. Please help me with this. I am using VB6 and SQL 2000.

Try something like:

Insert Into DestAccessTablename
From SQLSvrTablename IN "odbc;driver={SQL Server};server=myserver;database=pubs;uid=myuid;pwd=mypwd"

Please note that Microsoft indicates you will get better performance from an attached table than using the IN clause.

dependant on the amount of data involved....

1 create a linked table in the access database pointing to the SQL Server table

then do

Insert into AccessTable
 (column list)
 Select (column list)
 from linkedSQLServerTable
 order by (column list specifying the order the data should be inserted in)

if large amounts of data will be transfered then
it may be better to export the data from the SQL server database to a file
and then import that into access...

The VB code to attach the SQL Server table to the MSAccess database should look something like:

Set DAOtabledefobject = DAOdatabaseobject.tabledefs.append "attachedname"

DAOtabledefobject .connectstring = "odbc;driver={SQL Server};server=myserver;database=pubs;uid=myuid;pwd=mypwd"

DAOtabledefobject.RefreshLink

======================
Once the table is attached, you can execute the appending SQL in the MSAccess database to accomoplish the row append.

======================
NOTE: If you submit the SQL with the IN sub-clause (from my initial comment) you don't need to execute the attach code.
