public interface IFunction : IExpression
The IFunction type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | Add |
Mathematically adds the given expression to the current expression
(Inherited from IExpression.) |
| And |
Logically "ands" the given expression with the current expression
(Inherited from IExpression.) |
| Between |
Determines if the result is between the two given expressions
(Inherited from IExpression.) |
| Collate |
Collates the previous expression using the given collation instance (normally
this is used directly after Property(String) when
it is part of a Where(IExpression) or
OrderBy(IOrdering))
(Inherited from IExpression.) |
| Concat |
Concatenates the current and given expressions
(Inherited from IExpression.) |
| Divide |
Matehematically divides the current and given expressions
(Inherited from IExpression.) |
| EqualTo |
Returns an expression that will evaluate whether or not the given
and current expression are equal
(Inherited from IExpression.) |
| GreaterThan |
Returns an expression that will evaluate whether or not the given
expression is greater than the current one
(Inherited from IExpression.) |
| GreaterThanOrEqualTo |
Returns an expression that will evaluate whether or not the given
expression is greater than or equal to the current one
(Inherited from IExpression.) |
| In |
Returns an expression to test whether or not the given expression is contained
in the given list of expressions
(Inherited from IExpression.) |
| Is |
Returns an expression that will evaluate whether or not the given
expression is equal to the current one
(Inherited from IExpression.) |
| IsNot |
Returns an expression that will evaluate whether or not the given
expression is not equal to the current one
(Inherited from IExpression.) |
| IsNullOrMissing |
Gets an expression representing if the current expression is null
or missing (i.e. does not have a value)
(Inherited from IExpression.) |
| LessThan |
Returns an expression that will evaluate whether or not the given
expression is less than the current one
(Inherited from IExpression.) |
| LessThanOrEqualTo |
Returns an expression that will evaluate whether or not the given
expression is less than or equal to the current one
(Inherited from IExpression.) |
| Like |
Returns an expression that will evaluate whether or not the given
expression is "LIKE" the current one
(Inherited from IExpression.) |
| Match |
Returns an expression that will evaluate whether or not the given
expression full text matches the current one
(Inherited from IExpression.) |
| Modulo |
Returns an modulo math expression using the current and given expressions
as operands
(Inherited from IExpression.) |
| Multiply |
Returns a multiply expression using the current and given expressions as
operands
(Inherited from IExpression.) |
| NotBetween |
Determines if the result is not between the current and given expressions
(Inherited from IExpression.) |
| NotEqualTo |
Returns an expression that will evaluate whether or not the given
and current expression are not equal
(Inherited from IExpression.) |
| NotGreaterThan |
Returns an expression that will evaluate whether or not the given
expression is not greater than the current one
(Inherited from IExpression.) |
| NotGreaterThanOrEqualTo |
Returns an expression that will evaluate whether or not the given
expression is not greater than or equal to the current one
(Inherited from IExpression.) |
| NotIn |
Returns an expression to test whether or not the given expression is NOT contained
in the given list of expressions
(Inherited from IExpression.) |
| NotLessThan |
Returns an expression that will evaluate whether or not the given
expression is less than the current one
(Inherited from IExpression.) |
| NotLessThanOrEqualTo |
Returns an expression that will evaluate whether or not the given
expression is less than or equal to the current one
(Inherited from IExpression.) |
| NotLike |
Returns an expression that will evaluate whether or not the given
expression is "NOT LIKE" the current one
(Inherited from IExpression.) |
| NotMatch |
Returns an expression that will evaluate whether or not the given
expression doesn't full text match the current one
(Inherited from IExpression.) |
| NotNullOrMissing |
Gets an expression representing if the current expression is neither null
nor missing (i.e. has a value)
(Inherited from IExpression.) |
| NotRegex |
Returns an expression that will evaluate whether or not the given
expression doesn't regex match the current one
(Inherited from IExpression.) |
| Or |
Logically "ors" the given expression with the current expression
(Inherited from IExpression.) |
| Regex |
Returns an expression that will evaluate whether or not the given
expression regex matches the current one
(Inherited from IExpression.) |
| Subtract |
Mathematically subtracts the given expression to the current expression
(Inherited from IExpression.) |
