SPI_SCROLL_CURSOR_FETCH(3)	  PostgreSQL 9.2.7 Documentation       SPI_SCROLL_CURSOR_FETCH(3)

NAME
       SPI_scroll_cursor_fetch - fetch some rows from a cursor

SYNOPSIS
       void SPI_scroll_cursor_fetch(Portal portal, FetchDirection direction,
				    long count)

DESCRIPTION
       SPI_scroll_cursor_fetch fetches some rows from a cursor. This is equivalent to the SQL
       command FETCH.

ARGUMENTS
       Portal portal
	   portal containing the cursor

       FetchDirection direction
	   one of FETCH_FORWARD, FETCH_BACKWARD, FETCH_ABSOLUTE or FETCH_RELATIVE

       long count
	   number of rows to fetch for FETCH_FORWARD or FETCH_BACKWARD; absolute row number to
	   fetch for FETCH_ABSOLUTE; or relative row number to fetch for FETCH_RELATIVE

RETURN VALUE
       SPI_processed and SPI_tuptable are set as in SPI_execute if successful.

NOTES
       See the SQL FETCH(7) command for details of the interpretation of the direction and count
       parameters.

       Direction values other than FETCH_FORWARD may fail if the cursor's plan was not created
       with the CURSOR_OPT_SCROLL option.
