.rowSet()

Gets a row set of the data source for a specified parent key.

Returns a Rowset object. If parent-key refers to an existing Rowset object in the data source, then the details of this Rowset are returned in a Rowset object. Otherwise, the return value is undefined.

Syntax

The required parent-key must be one of the following:

•The literal string 'current'. This refers to the currently active row set of the data source.

•Any other key-string representing the row set's parent key. This must be an exact match to any Rowset object in the data source object in the data layer.

•An object that is a struct specifying one or more parent keys for at least one data source. This object is transformed to the corresponding key-string at runtime.

NOTE: For more on keys strings, go to the Rowset help topic. See also the Rowset.keysString() function.

Example

var rowSet = $.udb('EMP').rowSet('current');

if (rowSet.exists()) {
