All Recordset objects are constructed using records (rows)
and fields (columns). There are five types of Recordset
objects:
Table-type Recordset ::
********************
representation in code of a base table that you can use to
add, change,or delete records from a single database table
(Microsoft Jet workspaces only).
Dynaset-type Recordset ::
**********************
the result of a query that can have updatable records. A
dynaset-type Recordset object is a dynamic set of records
that you can use to add, change, or delete records from an
underlying database table or tables.
A dynaset-type Recordset object can contain fields from one
or more tables in a database. This type corresponds to an
ODBC keyset cursor.
Snapshot-type Recordset ::
**********************
a static copy of a set of records that you can use to find
data or generate reports. A snapshot-type Recordset object
can contain fields from one or more tables in a database
but can't be updated. This type corresponds to an ODBC
static cursor.
Forward-only-type Recordset::
***************************
identical to a snapshot except that no cursor is provided.
You can only scroll forward through records. This improves
performance in situations where you only need to make a
single pass through a result set. This type corresponds to
an ODBC forward-only cursor.
Dynamic-type Recordset ::
**********************
a query result set from one or more base tables in which
you can add,change, or delete records from a row-returning
query. Further, records other users add, delete, or edit in
the base tables also appear in your Recordset. This type
corresponds to an ODBC dynamic cursor (ODBCDirect
workspaces only).
