Please explain the use of rec.CursorLocation = adUseClient

Many times I would open a recordset to place in a datagrid in vb6 with

rec.Open (esql), conn, adOpenDynamic, adLockOptimistic

Open in new window

However, in one instance I needed to use the following:

rec.CursorLocation = adUseClient
                rec.Open (esql), conn, adOpenDynamic, adLockOptimistic

Open in new window

Can someone explain to me what the purpose is of the first line in this code.

One practical example of using a client side cursor is obtaining a record count.


Open in new window

Combined with a SELECT query, a server side cursor this would return -1 for this property. With a client side cursor you would obtain the number of records returned by the query.
