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…
SPI_cursor_close – close a cursor Synopsis void SPI_cursor_close(Portal portal) Description SPI_cursor_close closes a previously created cursor and releases its portal storage. All open cursors are closed automatically at the end of a transaction. SPI_cursor_close need only be invoked if it is desirable to release resources sooner. Arguments Portal portal portal containing the cursor
SPI_copytuple – make a copy of a row in the upper executor context Synopsis HeapTuple SPI_copytuple(HeapTuple row) Description SPI_copytuple makes a copy of a row in the upper executor context. This is normally used to return a modified row from a trigger. In a function declared to return a composite type, use SPI_returntuple instead. Arguments…
SPI_connect – connect a procedure to the SPI manager Synopsis int SPI_connect(void) Description SPI_connect opens a connection from a procedure invocation to the SPI manager. You must call this function if you want to execute commands through SPI. Some utility SPI functions can be called from unconnected procedures. If your procedure is already connected, SPI_connect…
