MOVE

Name

MOVE -- Repositions a cursor to another row.

Synopsis

MOVE [ 
direction
 ] [ 
count
 ]
     { IN | FROM } 
cursor

Parameters

direction: The direction you wish to move the specified cursor. See FETCH" or more information about the different usable directions.
count: The number of rows you wish to move the cursor.
cursor: The cursor that you are moving.

Results

The MOVE command will return the same errors and messages as the FETCH command; however, it will not return rows. See FETCH" for more information on what messages you may encounter.

Description

Use the MOVE command to reposition a cursor. This command operates essentially the same as the FETCH command. However, unlike FETCH, it does not use the cursor to return the traversed rows after it is repositioned.

Examples

The following examples assume a transaction and an already defined cursor (cur_employee) that uses the employees table for data. Using the MOVE command, this example moves the cursor one row forward in the result set:

booktown=# 
MOVE FORWARD 1 IN cur_employee;

MOVE

The only output returned by using this command is the message MOVE. The next example uses the FETCH command to display the second row of the cursor, after moving:

booktown=# 
FETCH 1 IN cur_employee;

 first_name | last_name
------------+-----------
 Michael    | Holloway
(1 row)
