View Methods

Drop

view.drop()

Drops a View and all its data.

Examples

Drop a View:

arangosh> v = db._createView("example", "arangosearch");
........> // or
arangosh> v = db._view("example");
arangosh> v.drop();
arangosh> db._view("example");

[ArangoView 84723, "example" (type arangosearch)]
null

Query Name

view.name()

Returns the name of the View.

Examples

Get View name:

arangosh> v = db._view("demoView");
arangosh> v.name();
Show execution results
Hide execution results
[ArangoView 95, "demoView" (type arangosearch)]
demoView

Rename

view.rename(new-name)

Renames a view using the new-name. The new-name must not already be used by a different view or collection in the same database. new-name must also be a valid view name. For more information on valid view names please refer to the naming conventions.

If renaming fails for any reason, an error is thrown.

The rename method is not available in clusters.

Examples

arangosh> v = db._createView("example", "arangosearch");
arangosh> v.name();
arangosh> v.rename("exampleRenamed");
arangosh> v.name();

[ArangoView 84766, "example" (type arangosearch)]
example
exampleRenamed

Query Type

view.type()

Returns the type of the View.

Examples

Get View type:

arangosh> v = db._view("demoView");
arangosh> v.type();
Show execution results

[ArangoView 95, "demoView" (type arangosearch)]
arangosearch

Query Properties

view.properties()

Returns the properties of the View. The format of the result is specific to each of the supported View Types.

Examples

Get View properties:

arangosh> v = db._view("demoView");
arangosh> v.properties();

  }, 
  "storedValues" : [ ], 
  "cleanupIntervalStep" : 2, 
  "primarySort" : [ ], 
  "primarySortCompression" : "lz4" 
}

Modify Properties

view.properties(new-properties, partialUpdate)

Modifies the properties of the view. The format of the result is specific to each of the supported View Types.

partialUpdate is an optional Boolean parameter (true by default) that determines how the new-properties object is merged with current View properties (adds or updates new-properties properties to current if true replaces all properties if false).

For the available properties of the supported View types, see:

Examples

Modify arangosearch View properties:

arangosh> v = db._view("example");
arangosh> v.properties();
........> // set cleanupIntervalStep to 12
arangosh> v.properties({cleanupIntervalStep: 12});
........> // add a link
arangosh> v.properties({links: {demo: {}}})
........> // remove a link
arangosh> v.properties({links: {demo: null}})

Add and remove inverted indexes from a search-alias View:

arangosh> var v = db._view("example");
arangosh> v.properties();
arangosh> v.properties({ indexes: [
........>   { collection: "coll", index: "inv1", operation: "del" },
........>   { collection: "coll", index: "inv3" }
........> ] });

    } 
  ]
