SPI_prepare_cursor
Synopsis
SPIPlanPtr SPI_prepare_cursor(const char * command, int nargs,
Oid * argtypes, int cursorOptions)Description
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.
Arguments
- const char * command
command string
- int nargs
number of input parameters ($1, $2, etc.)
- Oid * argtypes
pointer to an array containing the OIDs of the data types of the parameters
- int cursorOptions
integer bit mask of cursor options; zero produces default behavior
