OracleParameter.DbType Property


Gets or sets the DbType of the parameter.

 virtual property System::Data::DbType DbType { System::Data::DbType get(); void set(System::Data::DbType value); };
public override System.Data.DbType DbType { get; set; }
member this.DbType : System.Data.DbType with get, set
Public Overrides Property DbType As DbType

Property Value

One of the DbType values. The default is AnsiString.




The property was not set to a valid DbType.


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";

Public Sub CreateOracleDbParameter()
    Dim parameter As New OracleParameter()
    parameter.ParameterName = "pDName"
    parameter.DbType = DbType.String
    parameter.Value = "ENGINEERING"
    parameter.SourceColumn = "DName"
End Sub 


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.
