The application can specify the cursor type before executing a statement that creates a result set. It does this with the SQL_ATTR_CURSOR_TYPE statement attribute. If the application does not explicitly specify a type, a forward-only cursor will be used. To get a mixed cursor, an application specifies a keyset-driven cursor but declares a keyset size less than the result set size.
For keyset-driven and mixed cursors, the application can also specify the keyset size. It does this with the SQL_ATTR_KEYSET_SIZE statement attribute. If the keyset size is set to 0, which is the default, the keyset size is set to the result set size and a keyset-driven cursor is used. The keyset size can be changed after the cursor has been opened.
The application can also set the rowset size; for more information, see Using Block Cursors, earlier in this section.
