SPIPlanPtr SPI_prepare_cursor(const char * command, int nargs, Oid * argtypes, int cursorOptions)
SPI_prepare_cursor
is identical to SPI_prepare
, except that it also allows specification of the planner's "cursor options" parameter. This is a bit mask having the values shown in nodes/parsenodes.h for the options field of DeclareCursorStmt. SPI_prepare
always takes the cursor options as zero.
command string
number of input parameters ($1, $2, etc.)
pointer to an array containing the OIDs of the data types of the parameters
integer bit mask of cursor options; zero produces default behavior
