NAME
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(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.
