REFRESH MATERIALIZED VIEPostgreSQL 9.3.2 DocumentaREFRESH MATERIALIZED VIEW(7)NAMEREFRESH_MATERIALIZED_VIEW - replace the contents of a materialized view
SYNOPSIS
REFRESH MATERIALIZED VIEW name
[ WITH [ NO ] DATA ]
DESCRIPTION
REFRESH MATERIALIZED VIEW completely replaces the contents of a
materialized view. The old contents are discarded. If WITH DATA is
specified (or defaults) the backing query is executed to provide the
new data, and the materialized view is left in a scannable state. If
WITH NO DATA is specified no new data is generated and the materialized
view is left in an unscannable state.
PARAMETERS
name
The name (optionally schema-qualified) of the materialized view to
refresh.
NOTES
While the default index for future CLUSTER(7) operations is retained,
REFRESH MATERIALIZED VIEW does not order the generated rows based on
this property. If you want the data to be ordered upon generation, you
must use an ORDER BY clause in the backing query.
EXAMPLES
This command will replace the contents of the materialized view called
order_summary using the query from the materialized view's definition,
and leave it in a scannable state:
REFRESH MATERIALIZED VIEW order_summary;
This command will free storage associated with the materialized view
annual_statistics_basis and leave it in an unscannable state:
REFRESH MATERIALIZED VIEW annual_statistics_basis WITH NO DATA;
COMPATIBILITY
REFRESH MATERIALIZED VIEW is a PostgreSQL extension.
