## SPI_scroll_cursor_move

SPI_scroll_cursor_move — move a cursor

## Synopsis

    void SPI_scroll_cursor_move(Portal portal, FetchDirection direction,
                                long count)

## Description

`SPI_scroll_cursor_move` skips over some number of rows in a cursor. This is equivalent to the SQL command `MOVE`.

## 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 move for `FETCH_FORWARD` or `FETCH_BACKWARD`; absolute row number to move to for `FETCH_ABSOLUTE`; or relative row number to move to for `FETCH_RELATIVE`

## Return Value

`SPI_processed` is set as in `SPI_execute` if successful. `SPI_tuptable` is set to `NULL`, since no rows are returned by this function.

## Notes

See the SQL FETCH 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.
