Namespace: PPJ.Runtime

Assembly: PPJ.Web.50 (5.0.0.0)

Exposes a SAL value in the form used for database parameter binding.

public interface ISalType

VB.NET

Public Interface ISalType

Implementations provide the database type, underlying CLR value, and SAL null state. A SAL null is a value state rather than a null reference to this interface.

Example:

using PPJ.Runtime;

ISalType value = new SalString("Ada");
System.Data.DbType type = value.DbType; // String
object parameterValue = value.Value;   // "Ada"

ISalType missing = SalString.Null;
bool isNull = missing.IsNull;          // true

Properties

DbType

DbType: Gets the database type corresponding to this SAL value.

IsNull

Boolean: Gets whether this value represents SAL null.

Value

Object: Gets the underlying value for database binding.

The CLR type and null representation are determined by the implementing SAL type.
