OracleParameter.Size Property

Gets or sets the maximum size, in bytes, of the data within the column.

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

'Declaration
Public Overrides Property Size As Integer
'Usage
Dim instance As OracleParameter 
Dim value As Integer 

value = instance.Size

instance.Size = value

Property Value

Type: System.Int32
The maximum size, in bytes, of the data within the column. The default value is 0 (to be used when you do not want to specify the maximum size of the value).

Implements

IDbDataParameter.Size
IDbDataParameter.Size

Setting Size affects only the input value of a parameter. Return values and output parameters are not affected by this property.

The Size property is used for binary and string types.

For nonstring data types and ANSI string data, the Size property refers to the number of bytes. For Unicode string data, Size refers to the number of characters. The count for strings does not include the terminating character.

For variable-length data types, Size describes the maximum amount of data to transmit to the server. For example, for a Unicode string value, Size could be used to limit the amount of data sent to the server to the first one hundred characters.

For bidirectional and output parameters, and return values, you must set the value of Size. This is not required for input parameters, and if not explicitly set, the value of is inferred from the actual size of the specified parameter when a parameterized statement is executed.

The DbType, OracleType, and Size properties of a parameter can be inferred by setting Value. Therefore, you are not required to specify them. However, they are not exposed in OracleParameter property settings. For example, if the size of the parameter has been inferred, Size does not contain inferred value after statement execution.

For fixed length data types, the value of Size is ignored. It can be retrieved for informational purposes, and returns the maximum amount of bytes the provider uses when transmitting the value of the parameter to the server.

The following example creates a OracleParameter and sets some of its properties.

Public Sub CreateOracleParameter()
   Dim parameter As New OracleParameter("pDescription", OracleType.VarChar)
   parameter.IsNullable = True
   parameter.Direction = ParameterDirection.Output
   parameter.Size = 88
End Sub
