Classes

Class	Notes
BetweenExpression	The BetweenExpression class implements BetweenExpression that checks belonging to a range of values.
BinaryExpression	The BinaryExpression class implements BinaryExpression class and represents logical operations like And, Or, Greater Than etc.
ConstantExpression	The ConstantExpression implements ConstantExpression and represents values in WhereExpressions.
DateTimeNowExpression	The DateTimeNowExpression class represents the current database server date and time in Dynamic Where expressions.
DateTimePartExpression	The DateTimePartExpression class represents a call to the SQL function that extracts a part of given date like year, month etc in Dynamic Where expressions.
DateTimeTodayExpression	The DateTimeTodayExpression class represents the current database server date in Dynamic Where expressions.
FieldExpression	This class implements the FieldExpression and is used to represent table fields in Dynamic Where expressions. For example, see how the table field ID is represented in...
FunctionCallExpression
ListExpression	The ListExpression class is an implementation of ListExpression represents the collection of WhereExpression objects.
MacroExpression	The MacroExpression class is the implementation of MacroExpression.
NullExpression	The NullExpression implements NullExpression and represents a NULL value to be used as WhereExpression node.
ParameterExpression	This class is an implementation of ParameterExpression and is used to represent parameters in Dynamic Where expressions.
UnaryExpression	The UnaryExpression class is derived from the WhereExpression class and contains one operand (an expression) and a unary operator.
WhereExpression	The base abstract class for classes that represent WHERE expression tree nodes:
WhereValidator	The WhereValidator class checks WhereExpressions for errors. The main purpose of this class is to scan all objects of the WhereExpession tree and to make sure that it contains valid field names.
WhereVisitor	This class represents the implementation of Visitor patterns and sets the strategy of traversal for the WhereExpression tree.

Enums

Enum	Notes
BinaryOperator	The BinaryOperator enumeration denotes the binary operator applied to operands of a BinaryExpression expression.
DateTimePart	Parts of date and time that can be specified in DateTimePartExpression
FunctionKind
UnaryOperator	The UnaryOperator enumeration denotes the unary operator applied to operand of a UnaryExpression expression. The UnaryOperator enumeration is widely used when Dynamic Where expressions are created in code.
WhereKind	The WhereKind enumeration represents kind of the Dynamic Where expression.
