SPI_CURSOR_CLOSE(3)					  PostgreSQL 9.2.7 Documentation				       SPI_CURSOR_CLOSE(3)

NAME

       SPI_cursor_close - close a cursor

SYNOPSIS

       void SPI_cursor_close(Portal portal)

DESCRIPTION

       SPI_cursor_close closes a previously created cursor and releases its portal storage.

       All open cursors are closed automatically at the end of a transaction.  SPI_cursor_close need only be invoked if it is desirable to release
       resources sooner.

ARGUMENTS

       Portal portal
	   portal containing the cursor

NAME

       CLOSE - close a cursor

SYNOPSIS

       CLOSE { name | ALL }

DESCRIPTION

       CLOSE frees the resources associated with an open cursor.  After the cursor is closed, no subsequent operations are allowed on it. A cursor
       should be closed when it is no longer needed.

       Every non-holdable open cursor is implicitly closed when a transaction is terminated by COMMIT or ROLLBACK. A holdable cursor is implicitly
       closed  if  the	transaction  that  created  it	aborts via ROLLBACK. If the creating transaction successfully commits, the holdable cursor
       remains open until an explicit CLOSE is executed, or the client disconnects.

PARAMETERS

       name   The name of an open cursor to close.

       ALL    Close all open cursors.

NOTES

       PostgreSQL does not have an explicit OPEN cursor statement; a cursor is considered open when it is declared. Use the  DECLARE  [declare(7)]
       statement to declare a cursor.

       You can see all available cursors by querying the pg_cursors system view.

       If a cursor is closed after a savepoint which is later rolled back, the CLOSE is not rolled back; that is, the cursor remains closed.

EXAMPLES

       Close the cursor liahona:

       CLOSE liahona;

COMPATIBILITY

       CLOSE is fully conforming with the SQL standard. CLOSE ALL is a PostgreSQL extension.
