Gets or sets the value of the parameter.
Assembly: System.Data.OracleClient (in System.Data.OracleClient.dll)
For input parameters, the value is bound to the OracleCommand that is sent to the server. For output and return-value parameters, the value is set on completion of the OracleCommand and after the OracleDataReader is closed.
When you send a null parameter value to the server, you must specify DBNull, not null. A null value in the system is an empty object that has no value. DBNull is used to represent null values.
If the application specifies the database type, the bound value is converted to that type when the provider sends the data to the server. The provider tries to convert any type of value if it supports the IConvertible interface. Conversion errors may result if the specified type is not compatible with the value.
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.
The InputOutput, Output, and ReturnValue ParameterDirection values used by the Value property will be Microsoft .NET Framework data types, unless the input value was an Oracle data type (for example, OracleNumber or OracleString). This does not apply to REF CURSOR, BFILE, or LOB data types.
The property is overwritten by the Update method.
