Examples of AliasSymbol

com.odiago.flumebase.exec.AliasSymbol
A symbol which refers to another existing symbol. This allows a symbol to be referenced by a different name by the user. For example, in the context of "SELECT x FROM s", the field may be referenced as 'x' (the primary symbol), or also 's.x' (the alias).
org.teiid.query.sql.symbol.AliasSymbol
An AliasSymbol wraps a SingleElementSymbol and changes it's name. AliasSymbols should be used to perform the aliasing of elements in a SELECT clause. They should typically NOT be used elsewhere in a query. The alias symbol takes on the type of it's underlying SingleElementSymbol. AliasSymbols are typically applied to ElementSymbol, ExpressionSymbol, and AggregateSymbol.
