spi_cursor_open
SPI_CURSOR_OPEN(3) PostgreSQL 9.2.7 Documentation SPI_CURSOR_OPEN(3)
NAME
SPI_cursor_open - set up a cursor using a statement created with SPI_prepare
SYNOPSIS
Portal SPI_cursor_open(const char * name, SPIPlanPtr plan,
Datum * values, const char * nulls,
bool read_only)
DESCRIPTION
SPI_cursor_open sets up a cursor (internally, a portal) that will execute a statement prepared by SPI_prepare. The parameters have the same
meanings as the corresponding parameters to SPI_execute_plan.
Using a cursor instead of executing the statement directly has two benefits. First, the result rows can be retrieved a few at a time,
avoiding memory overrun for queries that return many rows. Second, a portal can outlive the current procedure (it can, in fact, live to the
end of the current transaction). Returning the portal name to the procedure's caller provides a way of returning a row set as result.
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)
Datum * values
An array of actual parameter values. Must have same length as the statement's number of arguments.
const char * nulls
An array describing which parameters are null. Must have same length as the statement's number of arguments. n indicates a null value
(entry in values will be ignored); a space indicates a nonnull value (entry in values is valid).
If nulls is NULL then SPI_cursor_open assumes that no parameters are null.
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.
