SPI_prepare_cursor (3) Linux Manual Page
SPI_prepare_cursor – prepare a statement, without executing it yet
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
