Properties
Name | Description | |
---|---|---|
ColumnName | Gets or sets an Identifier or a literal of type AsciiStringLiteral or UnicodeStringLiteral. Optional, may be nulla null reference (Nothing in Visual Basic). | |
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.) |
