Reference_Syntax.cursorType = “forwardOnly | keyset | dynamic | static | unspecified”
forwardOnly (default)
Identical to a static cursor, except that scrolling occurs only in a forward direction. This improves performance when you need to make only one pass through a record set.
Additions, changes, and deletions by other users are visible, and all types of movement through the record set are permitted, except for bookmarks, if the provider does not support them.
