Another behaviour that I have observed is that if I set UseUnicode and UnicodeEnvironment to true, the error does not raise

Re: ORA-01461: can bind a LONG value only for insert into a LONG column

I have sent an example project that demonstrates the problem.
In the sample project there is one check box to enable or disable Unicode.
I have observed that if I check unicode I can execute the update query, but if I try to execute the update query without unicode, and the error raises, after that, if I connect using unicode, then I can't execute the query without error.
Database characterset is AL23UTF8

I have found another interesting thing with Unidac. If I change the order of the parameters, I get another exception.
For example, If I use the next update statement, I get the subject error

Code: Select all

update Unidac_test.Pet_Prueba
set IDPACIENTE = :IDPaciente,
    FECHA = :Fecha, 
    RESULTADO = :RESULTADO, 
    PREFIJO = :Prefijo, 
    NRESULTADO = :NResultado, 
    TIPO = :TIPO, 
    NRESULTADO_CORREGIDO = :NResultado_Corregido,
   [b] TRESULTADO = :TRESULTADO, [/b]    
    TRESULTADOE = :TRESULTADOE, 
    PATOLOGIA = :Patologia, 
    IDTIPORESULTADO = :IDTipoResultado, 
    IDESTADORESULTADO = :IDESTADORESULTADO, 
    IDEQUIPO = :IDEQUIPO, 
    IDINSTRUMENTO = :IDINSTRUMENTO, 
    IDCENTROPROCESO = :IDCENTROPROCESO, 
    FECHA_RESULTADO = :FECHA_RESULTADO, 
    FECHA_PROCESO = :FECHA_PROCESO, 
    NALARMA = :NALARMA, 
    IDUSUARIO_RESULTADO = :IDUsuario_Resultado, 
    NREPETICION = :NRepeticion, 
    IDPRUEBAREF = :IDPruebaRef, 
    MARGEN_ULTIMO = :Margen_Ultimo, 
    DELTA_CHECK = :Delta_Check, 
    IDMETODO = :IDMetodo, 
    IDUNIDAD = :IDUnidad, 
    IDPRUEBAMU = :IDPruebaMU, 
    IDPRUINTERPRETACION = :IDPruInterpretacion,
    IDPRUINTERPRETACIONRES = :IDPruInterpretacionRes, 
    IDVALIDACION_TECNICA = :IDVALIDACION_TECNICA, 
    FECHA_VALIDACION_TECNICA = :FECHA_VALIDACION_TECNICA, 
    COMENTARIO = :COMENTARIO,  
    IDUSUARIO_VALIDACION_TECNICA = :IDUSUARIO_VALIDACION_TECNICA
where IDPETICIONPRUEBA = :IDPeticionPrueba
But if I move TRESULTADO to the end of the update statement, I get the error:
ORA-01483: invalid length for DATE or NUMBER bind variable

Code: Select all

update Unidac_test.Pet_Prueba
set IDPACIENTE = :IDPaciente,
    FECHA = :Fecha, 
    RESULTADO = :RESULTADO, 
    PREFIJO = :Prefijo, 
    NRESULTADO = :NResultado, 
    TIPO = :TIPO, 
    NRESULTADO_CORREGIDO = :NResultado_Corregido,
    TRESULTADOE = :TRESULTADOE, 
    PATOLOGIA = :Patologia, 
    IDTIPORESULTADO = :IDTipoResultado, 
    IDESTADORESULTADO = :IDESTADORESULTADO, 
    IDEQUIPO = :IDEQUIPO, 
    IDINSTRUMENTO = :IDINSTRUMENTO, 
    IDCENTROPROCESO = :IDCENTROPROCESO, 
    FECHA_RESULTADO = :FECHA_RESULTADO, 
    FECHA_PROCESO = :FECHA_PROCESO, 
    NALARMA = :NALARMA, 
    IDUSUARIO_RESULTADO = :IDUsuario_Resultado, 
    NREPETICION = :NRepeticion, 
    IDPRUEBAREF = :IDPruebaRef, 
    MARGEN_ULTIMO = :Margen_Ultimo, 
    DELTA_CHECK = :Delta_Check, 
    IDMETODO = :IDMetodo, 
    IDUNIDAD = :IDUnidad, 
    IDPRUEBAMU = :IDPruebaMU, 
    IDPRUINTERPRETACION = :IDPruInterpretacion,
    IDPRUINTERPRETACIONRES = :IDPruInterpretacionRes, 
    IDVALIDACION_TECNICA = :IDVALIDACION_TECNICA, 
    FECHA_VALIDACION_TECNICA = :FECHA_VALIDACION_TECNICA, 
    COMENTARIO = :COMENTARIO,  
    IDUSUARIO_VALIDACION_TECNICA = :IDUSUARIO_VALIDACION_TECNICA,

where IDPETICIONPRUEBA = :IDPeticionPrueba
Both runs fine selecting Unicode.

Another test with version 6.3.11.
Runs fine with and without unicode

Unfortunately we have not received your project demonstrating the described behavior. Please send this project together with the script to create DB objects used in it via the e-support form : https://www.devart.com (меню «Support»\«Request Support»).

We investigated the sent project and made some changes to its code. When processing the TRESULTADO (CLOB) field value change we clearly specified the query parameter type :

Code: Select all

       ...
      QueryUpdate.SpecificOptions.Values['TemporaryLOBUpdate'] := 'True';
      QueryUpdate.ParamByName( 'TRESULTADO').DataType := ftOraClob;
      QueryUpdate.ParamByName( 'TRESULTADO').ParamType := ptInput;
      QueryUpdate.ParamByName( 'TRESULTADO').AsBlobRef.AsString := <your CLOB value>;
       ...
      Connection.Commit;
After this we successfully updated the PET_PRUEBA table data.
Try to make this change to your project code and check its operability.

Thank you Maxim, but why runs on 6.3.11 and with parameter Unicode=True?.

Please specify whether these changes helped to solve the problem when using UniDAC 6.4.16 ?

Hello, the changes have solved the problem.

Could you please explain what changes from version 6.3.11 have been made in the component? I have search for release note changes in oracle that may affect clob, but I have found nothing about this issue.

Unfortunately, during testing using the sent project we did not find any difference in behavior between the latest version and UniDAC 6.3.11. Any change in our components behavior is reflected in history : https://www.devart.com/unidac/revision_history.html We will further follow this rule.
