Hmmm. May need goet more information from you to see what is going on here. Will it be too much trouble for asking the following: 1. trace An example to turn on trace: ... private static String url = "jdbc:db2://xxxxxxxxxxxx.vmec.svl.ibm.com:446/STLEC1" +":traceFile=c:/temp/jdbc4.log" +";traceLevel=" + com.ibm.db2.jcc.DB2BaseDataSource.TRACE_ALL + ";"; private static String user="xxxxxxxx"; private static String password="yyyyyyyy"; 0 people like this

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...

can you guide me where I could download the latest db2 jdbc driver? I will try to upgrade my local copy and I will try if that will fix the problem.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 More...
