OracleParameter.Direction Property

.NET Framework 4

Gets or sets a value that indicates whether the parameter is input-only, output-only, bidirectional, or a stored procedure return value parameter.

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

Syntax

C++

public override ParameterDirection Direction { get; set; }

Property Value

Type: System.Data.ParameterDirection
One of the ParameterDirection values. The default is Input.

Implements

IDataParameter.Direction
IDataParameter.Direction

Exceptions

Exception	Condition
ArgumentException	The property was not set to one of the valid ParameterDirection values.

Remarks

If the ParameterDirection is output, and execution of the associated OracleCommand does not return a value, the OracleParameter contains a null value.

Output, InputOut, and ReturnValue parameters returned by calling ExecuteReader cannot be accessed until you call Close on the OracleDataReader.

Examples

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

public void CreateOracleDbParameter() 
{
   OracleParameter parameter = new OracleParameter();
   parameter.ParameterName = "pDName";
   parameter.DbType = DbType.String;
   parameter.Value = "ENGINEERING";
   parameter.SourceColumn = "DName";
}
