I'm driving Weblogic 8.1.3 on WinTel.
DB2 8.1.4 on Sun64.
I'm using Weblogic DB2's Type 2 driver, which has been very
reliable - so far.
I have a PreparedStateme nt that updates perfectly when
the table is define so that one particular column has
datatype VARCHAR(2000) .
The table was recently modified so that the data type for
the column is now VARCHAR(4000).
SQL statements continue to work perfectly when inserting data
consisting of 2000 or fewer characters.
Upon updating a column with 3990 characters the following
error occurs :
COM.ibm.db2.jdb c.DB2Exception : [IBM][CLI Driver] CLI0109E String data
right truncation. SQLSTATE=22001
I haven't a clue as to the source of the problem and that's
where your suggestions would be very helpful.
The DB2 Message Reference for CLI0190E suggests to use
SQLSetParam or SQLBindParamete r, but that doesn't sound like
advice relavant for a JDBC application.
A few google posts suggest that this is a database configuration
issue and that a change in a database configuration file
might fix things. If this is the case more information on
that would be very useful.
In some Google posts developers fathomed that this was an
issue which could be resolved with a different database
driver. Does the type 2 driver "not support" varchar 4000?
Thanks.

Strange. I have a javascript alert that tells me that the length of the
string coming from the textbox is 3999. But somehow, by the time
the data attempts to get saved the length of the String is 4157.
I did try out the WebLogic Type 4 driver for DB2. The message was :
[BEA][DB2 JDBC Driver][DB2]Character data, right tuncation occured; for
example, an update or insert value is a string that is too long forthe
column, or a datetimevalue cannot be assigned to a host variable,
because it is too small.
It looks like validating the length of the data on the server side
will solve my problems.
...
BTW, Attempting to save with 27000 characters and the Type 2 driver
killed
the server and crashed the JVM.
Yes. We heartily recommend sticking to a type-4 driver, which
won't be able to kill the Application Server.

From hs_err_pid2224. log :
An unexpected exception has been detected in native code outside the

One thing that's not so great about the type-4 driver is that the
SQL statement :
"VALUES NEXTVAL FOR SCHEMA_NAME.SEQ UENCE_NAME"
results in :
[BEA][DB2 JDBC Driver][DB2]UNACCEPTABLE SQL STATEMENT"

Hi. Show me the few lines of JDBC that try to use
this SQL and I'll see about getting it fixed for you.

If you like, followups can go to the online BEA JDBC newsgroup.

Not in this case since the text consisted of 3999 'a' characters.
I fathom that it's an IE/textarea/wrap issue.

Needs further examination on the output. Just do a System.out.prin t(...)
on the String you receive from the webform to see if there are any \n or
\r in it.

How do you expect to store a column larger than 4K in 4K page (and 4K
bufferpool)? Long varchar is OK because the data is not stored in the row
(like LOB's) and it does not make use of bufferpools (data is read and
written directly to disk).
I know that. I wasn't asking a question, I was just sharing an experience.

Hi
The maximum length of a nvarchar could be 4000 characters while that of
varchar could be 8000.
We are trying to use unicode which would require that the datatype for
one our fields be converted from varchar to nvarchar. But looks like
this would result in loss of existing data.
Is there a way to do this without loss of data?
