SPI_CURSOR_OPEN_WITH_PARAMLIST(3) PostgreSQL 12.3 Documentation SPI_CURSOR_OPEN_WITH_PARAMLIST(3)
NAME
SPI_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)
DESCRIPTION
SPI_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.
