SPI_cursor_move

SPI_cursor_move — move a cursor

Synopsis

void SPI_cursor_move(Portal portal, bool forward, long count)

Description

SPI_cursor_move skips over some number of rows in a cursor. This is equivalent to a subset of the SQL command MOVE (see SPI_scroll_cursor_move for more functionality).

Arguments

Portal portal: portal containing the cursor
bool forward: true for move forward, false for move backward
long count: maximum number of rows to move

Notes

Moving backward may fail if the cursor's plan was not created with the CURSOR_OPT_SCROLL option.
