NAME

6       SPI_prepare_cursor - prepare a statement, without executing it yet
7

SYNOPSIS

9       SPIPlanPtr SPI_prepare_cursor(const char * command, int nargs,
10                                     Oid * argtypes, int cursorOptions)
11

DESCRIPTION

13       SPI_prepare_cursor is identical to SPI_prepare, except that it also
14       allows specification of the planner's “cursor options” parameter. This
15       is a bit mask having the values shown in nodes/parsenodes.h for the
16       options field of DeclareCursorStmt.  SPI_prepare always takes the
17       cursor options as zero.
18
19       This function is now deprecated in favor of SPI_prepare_extended.
20

ARGUMENTS

22       const char * command
23           command string
24
25       int nargs
26           number of input parameters ($1, $2, etc.)
27
28       Oid * argtypes
29           pointer to an array containing the OIDs of the data types of the
30           parameters
31
32       int cursorOptions
33           integer bit mask of cursor options; zero produces default behavior
34

RETURN VALUE

36       SPI_prepare_cursor has the same return conventions as SPI_prepare.
37

NOTES

39       Useful bits to set in cursorOptions include CURSOR_OPT_SCROLL,
40       CURSOR_OPT_NO_SCROLL, CURSOR_OPT_FAST_PLAN, CURSOR_OPT_GENERIC_PLAN,
41       and CURSOR_OPT_CUSTOM_PLAN. Note in particular that CURSOR_OPT_HOLD is
42       ignored.
