                                                                                                                           Hello Everyone,
     We are having problem w/ retrieving data column that has special character from the db2 database. when we try to use the recordset.getString(columname) method we catch the exception below. Is there any workaround how to retrieve the data w/ out exception?
     Error catch:
     R com.ibm.db2.jcc.b.SqlException: jcct4106512306http://3.50.152 Caught java.io.CharConversionException. See attached Throwable for details. ERRORCODE=-4220, SQLSTATE=null
     I tried also using getBytes method and catch different error which is :      Invalid data conversion: Wrong result column type for requested conversion. ERRORCODE=-4461, SQLSTATE=42815
     anyone has the idea how to solve this problem?

         2. The data type of the column is Varchar , size = 256 , nullable = Yes
         3. I can reproduce the problem using below code      System.out.println(recordset.getString("columname"));
         Have you experience such case? I tried to use the getBytes method too and it seems like it doesn‘t work.
         think and do something different, something has never been done and seen before..

         2. The data type of the column is Varchar , size = 256 , nullable = Yes
         3. I can reproduce the problem using below code      System.out.println(recordset.getString("columname"));
         Have you experience such case? I tried to use the getBytes method too and it seems like it doesn‘t work.
         think and do something different, something has never been done and seen before..                                      
    More...                   
                                     
                                                                                              Hi Allen,
         No. Unforturnatly I am not having any luck to recrete the problem.
         You know you are using a very very old JDBC driver: 3.50.152. Do you have to use a such old driver? The current driver is at 3.62.
         Anyway, I was thinking you may be able to get a trace like following so I can get more information about the problem:      each line should starts with jcc, for example
    jccTime:2010-11-08-21:13:38.031Thread:mainResultSet@7fc07fc getString (2) called jccTime:2010-11-08-21:13:38.046Thread:mainResultSet@7fc07fc getString () returned 2010-11-08 21:13:37 PR?CESS-1 2010-11-08 21:13:37.453
         So, you see the special character: ?      is okay.      Best regards,
         Sasami

                                                                                              You can also cast the column to CHAR FOR BIT DATA and do the conversion in code.
