•A Static Cursor doesn't reflect data changes made to the DB once the ResultSet has been created whereas a Dynamic Cursor reflects the changes as and when they happen.

•A Static Cursor is much more performant than a Dynamic Cursor as it doesn't require further interaction with the DB server.

•A static cursor supports both Relative and Absolute Positioning whereas a Dynamic Cursor supports only Relative Positioning.

•A Static Cursor can be used for Bookmarking purposes as the data returned is static whereas a Dynamic Cursor can't be used for the same

static cursor refers always one work area associated with cursor.
where as ref cursor refers different work area in memory.
ref cursor is used to declare a cursor with out select statement.

<h2>Static</h2>

<blockquote>
 The complete result set of a static cursor is built in tempdb when the
 cursor is opened. A static cursor always displays the result set as it
 was when the cursor was opened. Static cursors detect few or no
 changes, but consume relatively few resources while scrolling.
</blockquote>

<h2>Dynamic</h2>

<blockquote>
 Dynamic cursors are the opposite of static cursors. Dynamic cursors
 reflect all changes made to the rows in their result set when
 scrolling through the cursor. The data values, order, and membership
 of the rows in the result set can change on each fetch. All UPDATE,
 INSERT, and DELETE statements made by all users are visible through
 the cursor.
