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.
