Syntax

Visual Basic
C#

'Declaration
 
Public Overrides Property Value As Object

public override object Value {get; set;}

Property Value

An System.Object that is the value of the parameter. The default value is null.

Remarks

For input parameters, the value is bound to the DB2Command that is sent to the server. For output and return-value parameters, the value is set on completion of the DB2Command and after the DB2DataReader is closed.

When sending a null parameter value to the server, the user must specify System.DBNull, not null. A null value in the system is an empty object that has no value. System.DBNull is used to represent null values.

If the application specifies the database type, the bound value is converted to that type when the provider sends the data to the server. The provider attempts to convert any type of value if it supports the IConvertible interface. Conversion errors may result if the specified type is not compatible with the value.

The DbType property can be inferred by setting Value. If applicable, the size, precision, and scale will also be inferred from Value.

The Value property is overwritten by the System.Data.Common.DbDataAdapter.Update() method.
