SqlBoolean Structure

Represents an integer value that is either 1 or 0 to be stored in or retrieved from a database.

Namespace: System.Data.SqlTypes
Assembly: System.Data (in System.Data.dll)

Syntax

Visual Basic (Declaration)

<SerializableAttribute> _
Public Structure SqlBoolean _
    Implements INullable, IComparable, IXmlSerializable

Visual Basic (Usage)

Dim instance As SqlBoolean

[SerializableAttribute]
public struct SqlBoolean : INullable, 
    IComparable, IXmlSerializable

Visual C++

[SerializableAttribute]
public value class SqlBoolean : INullable, 
    IComparable, IXmlSerializable

JScript

JScript supports the use of structures, but not the declaration of new ones.

Remarks

Any non-zero value is interpreted as 1.

The key difference between a SqlBoolean structure and a standard Boolean value is that, where a standard Boolean has two possible values, true and false, a SqlBoolean structure has three possible values, True, False, or Null.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
