NAME

6       SPI_cursor_open_with_paramlist - set up a cursor using parameters
7

SYNOPSIS

9       Portal SPI_cursor_open_with_paramlist(const char *name,
10                                             SPIPlanPtr plan,
11                                             ParamListInfo params,
12                                             bool read_only)
13

DESCRIPTION

15       SPI_cursor_open_with_paramlist sets up a cursor (internally, a portal)
16       that will execute a statement prepared by SPI_prepare. This function is
17       equivalent to SPI_cursor_open except that information about the
18       parameter values to be passed to the query is presented differently.
19       The ParamListInfo representation can be convenient for passing down
20       values that are already available in that format. It also supports use
21       of dynamic parameter sets via hook functions specified in
22       ParamListInfo.
23
24       The passed-in parameter data will be copied into the cursor's portal,
25       so it can be freed while the cursor still exists.
26

ARGUMENTS

28       const char * name
29           name for portal, or NULL to let the system select a name
30
31       SPIPlanPtr plan
32           prepared statement (returned by SPI_prepare)
33
34       ParamListInfo params
35           data structure containing parameter types and values; NULL if none
36
37       bool read_only
38           true for read-only execution
39

RETURN VALUE

41       Pointer to portal containing the cursor. Note there is no error return
42       convention; any error will be reported via elog.
