The .NET API Reference documentation has a new home. Visit the .NET API Browser on docs.microsoft.com to see the new experience.

Gets or sets the DbType of the parameter.

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

public override DbType DbType { get; set; }

Property Value

Type: System.Data.DbType

One of the DbType values. The default is AnsiString.

Exception Condition
ArgumentOutOfRangeException

The property was not set to a valid DbType.

The OracleType and DbType are linked. Therefore, setting the DbType changes the OracleType to a supporting OracleType.

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 String data types the default is AnsiString.

For a list of the supported data types, see the appropriate OracleType member. For more information, see DataAdapter Parameters.

The following example creates an 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";
 }
