note

This article is about the embeddedKeyCols() function of the DataSourceContainer object.

$.udb(ds).embeddedKeyCols()

Gets a list of key columns that are used in the relation of an embedded data source.

Returns a collection of columns.

Syntax

$.udb( *ds* ).embeddedKeyCols( *embedded-data-source-name* )

The optional ds is a data source selector.

The optional embedded-data-source-name is a string that identifies a data source embedded within the data source. For embedded data sources at a deeper level, use one or more forward slash symbols (‘/’) to descend to the deeper level. If embedded-data-source-name is not specified, all embedded key columns in scope are returned.

$.udbMeta('EMP').embeddedKeyCols('Embedded DEPARTMENT');

$.udbMeta('EMP').embeddedKeyCols('Embedded DEPARTMENT/Embedded COMPANY');
