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.
