Create New Widgets


Publishing views as widgets is a deprecated feature and it may be removed in future major versions of the Denodo Platform.

The section Features Deprecated in Denodo Platform 8.0 lists all the features that are deprecated.

Use the statement CREATE WIDGET to create a new widget.

Syntax of the CREATE WIDGET statement
CREATE [ OR REPLACE ] WIDGET <name:identifier>
    [ DISPLAYNAME = <literal> ]
    [ DESCRIPTION = <literal> ]
    ELEMENTTOPUBLISH = [ <database:identifier>.]<element name:identifier>
    CHUNKSIZE = <integer>
    CHUNKTIMEOUT = <integer>
    QUERYTIMEOUT = <integer>
    POOLENABLED = <boolean>
    POOLINITSIZE = <integer>
    POOLMAXACTIVE = <integer>
    I18N = <identifier>
    HELPMODEENABLED = <boolean>
    [ CUSTOMIZEDHELPMODECONTENTS = <html_fragment:literal> ]

Below is a brief description of some of the parameters of this statement:

  • ELEMENTTOPUBLISH: Name of the view (optionally prefixed with the identifier of a database), base view or stored procedure to publish.

  • HELPMODEENABLED: Enables the Help Mode for the widget. In the three widget platforms, a widget might have a help mode used to display information about the widget. If this parameter is true, but the CUSTOMIZEDHELPMODECONTENTS parameter is not present, the widget’s help mode will display a text with instructions on how to use the widget.

  • CUSTOMIZEDHELPMODECONTENTS: HTML fragment that will be shown when the user opens the widget’s Help Mode. This parameter is only useful if HELPMODEENABLED is true.

  • CHUNKSIZE, CHUNKTIMEOUT, QUERYTIMEOUT: Their interpretation is the same as in any other Virtual DataPort client.

  • POOLENABLED: If true, the connection pool will be enabled (highly recommended).

  • POOLINITSIZE: Initial number of connections to be opened in the pool.

  • POOLMAXACTIVE: Maximum number of connections in the pool. If this is a negative value, then the number is not limited.

  • PUBLISHCUSTOMTABLEEVENT: Enables the option that the widget exported to a JSR-286 Portlet can send complex objects to other portlets. These complex objects contain the whole result of the executed query view/stored procedure obtained from Virtual DataPort (see section Export to JSR-168 or JSR-286 Portlet of the Administration Guide).
