OracleParameter.Direction Property

Definition

Namespace:

System.Data.OracleClient

Assembly:

System.Data.OracleClient.dll

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

C#

public override System.Data.ParameterDirection Direction { get; set; }

Property Value

ParameterDirection

One of the ParameterDirection values. The default is Input.

Implements

Direction

Exceptions

ArgumentException

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

Examples

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

C#

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

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.
