SPI_CURSOR_OPEN_WITH_PARPostgreSQL 9.3.2 DocuSPI_CURSOR_OPEN_WITH_PARAMLIST(3)NAMESPI_cursor_open_with_paramlist - set up a cursor using parameters
SYNOPSIS
Portal SPI_cursor_open_with_paramlist(const char *name,
SPIPlanPtr plan,
ParamListInfo params,
bool read_only)
DESCRIPTIONSPI_cursor_open_with_paramlist sets up a cursor (internally, a portal)
that will execute a statement prepared by SPI_prepare. This function is
equivalent to SPI_cursor_open except that information about the
parameter values to be passed to the query is presented differently.
The ParamListInfo representation can be convenient for passing down
values that are already available in that format. It also supports use
of dynamic parameter sets via hook functions specified in
ParamListInfo.
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
SPIPlanPtr plan
prepared statement (returned by SPI_prepare)
ParamListInfo params
data structure containing parameter types and values; NULL if none
bool read_only
true for read-only execution
RETURN VALUE
Pointer to portal containing the cursor. Note there is no error return
convention; any error will be reported via elog.
