Examples of ElementSymbol

org.teiid.query.sql.symbol.ElementSymbol

This is a subclass of Symbol representing a single element. An ElementSymbol also is an expression and thus has a type. Element symbols have a variety of attributes that determine how they are displayed - a flag for displaying fully qualified and an optional vdb name.

The "isExternalReference" property indicates whether the element symbol refers to an element from a group outside the current command. Typically this is set to false. Common uses when this is set to true are for variables used within a command, correlated elements within a command, etc.
