OracleBoolean Structure
Represents the value returned from a database comparison operation between Oracle data types, and exposes methods used to perform data type conversions.
Assembly: System.Data.OracleClient (in System.Data.OracleClient.dll)
The OracleBoolean type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | OracleBoolean(Boolean) | Initializes a new instance of the OracleBoolean structure using the specified Boolean. |
![]() | OracleBoolean(Int32) | Initializes a new instance of the OracleBoolean structure using the specified integer. |
| Name | Description | |
|---|---|---|
![]() ![]() | And | Computes the bitwise AND of two specified OracleBoolean structures. |
![]() | CompareTo | Compares this OracleBoolean structure to a specified object and returns an indication of their relative values. |
![]() | Equals(Object) | Compares the supplied object parameter to the OracleBoolean. (Overrides ValueType::Equals(Object).) |
![]() ![]() | Equals(OracleBoolean, OracleBoolean) | Compares two OracleBoolean structures to determine if they are equal. |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Returns the hash code for this instance. (Overrides ValueType::GetHashCode().) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() ![]() | NotEquals | Compares two instances of OracleBoolean to determine if they are not equal. |
![]() ![]() | OnesComplement | Performs a ones complement operation on the supplied OracleBoolean structures. |
![]() ![]() | Or | Performs a bitwise OR operation on the two specified OracleBoolean structures. |
![]() ![]() | Parse | Converts the specified String representation of a logical value to its OracleBoolean equivalent. |
![]() | ToString | Converts the current Value to a string. (Overrides ValueType::ToString().) |
![]() ![]() | Xor | Performs a bitwise exclusive-OR operation on the supplied parameters. |
| Name | Description | |
|---|---|---|
![]() ![]() | BitwiseAnd | Computes the bitwise AND of two specified OracleBoolean structures. |
![]() ![]() | BitwiseOr | Computes the bitwise OR of its two OracleBoolean operands. |
![]() ![]() | Equality | Compares two instances of an OracleBoolean for equality. |
![]() ![]() | ExclusiveOr | Performs a bitwise exclusive-OR operation on the supplied OracleBoolean parameters. |
![]() ![]() | Explicit(OracleBoolean to Boolean) | Converts an OracleBoolean to a Boolean. |
![]() ![]() | Explicit(OracleNumber to OracleBoolean) | Converts the OracleNumber parameter to an OracleBoolean structure. |
![]() ![]() | Explicit(String to OracleBoolean) | Converts a string to an OracleBoolean structure. |
![]() ![]() | False | Used to test the Value of the OracleBoolean to determine whether it is false. |
![]() ![]() | Implicit(Boolean to OracleBoolean) | Converts a Boolean value to an OracleBoolean. |
![]() ![]() | Inequality | Compares two instances of OracleBoolean for inequality. |
![]() ![]() | LogicalNot | Performs a NOT operation on an OracleBoolean. |
![]() ![]() | OnesComplement | Performs a one's complement operation on the specified OracleBoolean. |
![]() ![]() | True | Used to test the Value of the OracleBoolean to determine whether it is true. |
| Name | Description | |
|---|---|---|
![]() ![]() | False | Represents a false value that can be assigned to the Value property of an instance of the OracleBoolean structure. |
![]() ![]() | Null | Represents a null value that can be assigned to the Value property of an instance of the OracleBoolean structure. |
![]() ![]() | One | Represents a value of one that can be assigned to the Value property of an instance of the OracleBoolean structure. |
![]() ![]() | True | Represents a true value that can be assigned to the Value property of an instance of the OracleBoolean structure. |
![]() ![]() | Zero | Represents a value of zero that can be assigned to the Value property of an instance of the OracleBoolean structure. |
The key difference between an OracleBoolean structure and a standard Boolean value is that, where a standard Boolean has two possible values, true and false, an OracleBoolean structure has three possible values, True, False, or Null.
An OracleBoolean structure does not map to an Oracle Boolean data type; it is exposed as a convenience support class.
