SPI_CURSOR_OPEN_WITH_ARGS(3) PostgreSQL 9.2.7 Documentation SPI_CURSOR_OPEN_WITH_ARGS(3)NAME
SPI_cursor_open_with_args - set up a cursor using a query and parameters
SYNOPSIS
Portal SPI_cursor_open_with_args(const char *name,
const char *command,
int nargs, Oid *argtypes,
Datum *values, const char *nulls,
bool read_only, int cursorOptions)
DESCRIPTION
SPI_cursor_open_with_args sets up a cursor (internally, a portal) that will execute the specified query. Most of the parameters have the
same meanings as the corresponding parameters to SPI_prepare_cursor and SPI_cursor_open.
For one-time query execution, this function should be preferred over SPI_prepare_cursor followed by SPI_cursor_open. If the same command is
to be executed with many different parameters, either method might be faster, depending on the cost of re-planning versus the benefit of
custom plans.
The passed-in parameter data will be copied into the cursor's portal, so it can be freed while the cursor still exists.
ARGUMENTS
const char * name
name for portal, or NULL to let the system select a name
const char * command
command string
int nargs
number of input parameters ($1, $2, etc.)
Oid * argtypes
an array containing the OIDs of the data types of the parameters
Datum * values
an array of actual parameter values
const char * nulls
an array describing which parameters are null
If nulls is NULL then SPI_cursor_open_with_args assumes that no parameters are null.
bool read_only
true for read-only execution
int cursorOptions
integer bit mask of cursor options; zero produces default behavior
RETURN VALUE
Pointer to portal containing the cursor. Note there is no error return convention; any error will be reported via elog.
