Class TConstant

Namespace

gudusoft.gsqlparser.nodes

Assembly

gudusoft.gsqlparser.dll

A constant (sometimes called a literal) specifies a value. Constants are classified as:

• string(text) constants,
• numeric constants,Numeric constants are further classified as integer, floating-point, or decimal.
• datetime constants,
• interval constants
• boolean constants.
value of literal can be get by calling method gudusoft.gsqlparser.nodes.TConstant._valueToken.
