Cursors
When using the DB Access Module for MySQL, the DB Interface Module class
RWDBCursor is implemented using the capabilities of the MySQL Library. Cursors can be both sequential and scrollable.
The default cursor type implemented in the DB Access Module for MySQL is sequential cursor.
Scrolling cursors are available through the DB Access Module for MySQL, and are implemented by using the mysql_data_seek() method to move arbitrarily through the result set stored in the client from a mysql_store_result() call.
NOTE: Due to the way scrolling cursor support is implemented in the DB Access Module for MySQL, all input values are sent as literals upon execution of the SQL statement.
