NAME

       SPI_cursor_fetch - fetch some rows from a cursor

SYNOPSIS

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

DESCRIPTION

       SPI_cursor_fetch fetches some rows from a cursor. This is equivalent to a subset of the
       SQL command FETCH (see SPI_scroll_cursor_fetch for more functionality).

ARGUMENTS

       Portal portal
           portal containing the cursor

       bool forward
           true for fetch forward, false for fetch backward

       long count
           maximum number of rows to fetch

RETURN VALUE

       SPI_processed and SPI_tuptable are set as in SPI_execute if successful.

NOTES

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