Subject [jira] [Commented] (CASSANDRA-9838) Unable to update an element in a static list
Date Fri, 17 Jul 2015 14:42:05 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-9838?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14631417#comment-14631417

Philip Thompson commented on CASSANDRA-9838:
--------------------------------------------

I'm getting {{InvalidRequest: code=2200 [Invalid query] message="Attempted to set an element
on a list which is null"}} instead, on the same operations.

[~thobbs], are these operations valid?

>          Components: Core
>         Environment: Cassandra 2.1.5 on Linux

> I created a table in cassandra  (my_table) which has a static list column sizes_list.

> I created a new row and initialized the list sizes_list as having one element. 
> {{UPDATE my_table SET sizes_list = sizes_list + [0] WHERE view_id = 0x01}}
> Now I m trying to update the element at index '0' with a statement like this
> {code}insert into my_table (my_id, is_deleted , col_id1, col_id2) values (0x01, False,
0x00, 0x00);
> UPDATE my_table SET sizes_list[0] = 100 WHERE my_id = 0x01 ;
> {code}
> Now I see an error like this: 
> {{InvalidRequest: code=2200 [Invalid query] message="List index 0 out of bound, list
has size 0"}}
> If I change my list to a non-static list, it works fine!
