Subject [jira] Commented: (DERBY-3746) java.sql.SQLException: The exception 'java.lang.NullPointerException' was thrown while evaluating an expression.
Date Tue, 23 Feb 2010 02:53:27 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3746?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12837047#action_12837047
] 

Matthew Cooper commented on DERBY-3746:
---------------------------------------

I just got this for the first time - no particular cause that I can see. Restarting the JVM
fixed it.

So does "Triaged for 10.5.2." mean it is going to get fixed in that version - and any ideas
when that is likely to be?

(Oh and Hi to Sitsky - small world eh?)

>             Project: Derby
>          Issue Type: Bug
>          Components: Store
>    Affects Versions: 10.3.1.4

> Hi
>  
> Following exception occurs while running our application with embedded derby database.
The application uses multithreading. This exception occurs while insert query is executed.
The insert query is run using JDBC:
>  
> insert into sign (sign, month, day, offset, digest) values (?,?,?,?,?). 
>  
> The table for which insert query is fired is:
>  
> create table sign(ID  INTEGER NOT NULL GENERATED ALWAYS AS IDENTITY PRIMARY KEY, sign
varchar(32), month char(6) not null, day char(2) not null, offset bigint not null, digest
varchar(32) for bit data not null)
>  
> There are multiple threads inserting data in database. I tried to search a lot on net
but could not find any solution. We're using derby 10.3.1.4. Not sure about the root cause.
It will be great if anybody provides some solution because it is creating lot of problems
in our application.
