Properties

	Name	Description
	ColumnName	Gets or sets an Identifier or a literal of type AsciiStringLiteral or UnicodeStringLiteral. Optional, may be null.
	Expression	Gets or sets a select expression that can be any expression, if this is non-null then this select expression is a regular expression. At present this AST class expresses either an expression or a wildcard. Because a SelectExpressions can do so much more, we may want to go to a derivation approach, where this class would be a base -- or there may be another more elegant approach. For now, this is a basic design to support SELECT * FROM foo.
	FirstTokenIndex	Gets or sets the first token index. (Inherited from TSqlFragment.)
	FragmentLength	Gets the fragment length. (Inherited from TSqlFragment.)
	LastTokenIndex	Gets or sets the last token index. (Inherited from TSqlFragment.)
	ScriptTokenStream	Gets or sets a list of token streams. (Inherited from TSqlFragment.)
	StartColumn	Gets the starting column. (Inherited from TSqlFragment.)
	StartLine	Gets the starting line. (Inherited from TSqlFragment.)
	StartOffset	Gets the fragment start offset value. (Inherited from TSqlFragment.)
