C# Class Remotion.Linq.SqlBackend.SqlStatementModel.NamedExpression

NamedExpression holds an expression and a name for it. If the name is null, a default name is used (or omitted if possible). When a NamedExpression holds an expression resolved to a SqlEntityExpression, the entity's name is set to the NamedExpression's name. Otherwise, the NamedExpression is retained and used to emit "AS ..." clauses in SQL generation. Therefore, NamedExpression must only be used in parts of a SqlStatement where "AS ..." clauses are allowed.
