SPI_scroll_cursor_move - move a cursor

Synopsis

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

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

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

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

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.
