Properties

  Name Description
Public property ColumnName Gets or sets an Identifier or a literal of type AsciiStringLiteral or UnicodeStringLiteral. Optional, may be nulla null reference (Nothing in Visual Basic).
Public property 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.
Public property FirstTokenIndex Gets or sets the first token index. (Inherited from TSqlFragment.)
Public property FragmentLength Gets the fragment length. (Inherited from TSqlFragment.)
Public property LastTokenIndex Gets or sets the last token index. (Inherited from TSqlFragment.)
Public property ScriptTokenStream Gets or sets a list of token streams. (Inherited from TSqlFragment.)
Public property StartColumn Gets the starting column. (Inherited from TSqlFragment.)
Public property StartLine Gets the starting line. (Inherited from TSqlFragment.)
Public property StartOffset Gets the fragment start offset value. (Inherited from TSqlFragment.)
