FORWARD_ONLY
ResultSet only permits forward navigation
SCROLL_INSENSITIVE
ResultSet permits any type of navigation, changes to the original data are, however, not noted
SCROLL_SENSITIVE
ResultSet permits any type of navigation, changes to the original data impact on the ResultSet
Database Access
Note – VBA : A ResultSet containing the READ_ONLY and SCROLL_INSENSITIVE properties corresponds
to a record set of the Snapshot type in ADO and DAO.
When using the ResultSet's UPDATEABLE and SCROLL_SENSITIVE properties, the scope of function of a
ResultSet is comparable with a Dynaset type Recordset from ADO and DAO.
Methods for Navigation in ResultSets
If a ResultSet is a SCROLL_INSENSITIVE or SCROLL_SENSITIVE type, it supports a whole range of methods
for navigation in the stock of data. The central methods are:
next()
navigation to the next data record
previous()
first()
last()
navigation to the previous data record
navigation to the first data record
navigation to the last data record
beforeFirst()
navigation to before the first data record
afterLast()
navigation to after the last data record
All methods return a Boolean parameter which specifies whether the navigation was successful.
To determine the current cursor position, the following test methods are provided and all return a Boolean value:
isBeforeFirst()
ResultSet is before the first data record
isAfterLast()
isFirst()
isLast()
ResultSet is after the last data record
ResultSet is the first data record
ResultSet is the last data record
Modifying Data Records
If a ResultSet has been created with the ResultSetConcurrency = UPDATEABLE value, then its content can
be edited. This only applies for as long as the SQL command allows the data to be re-written to the database
