Jonathan Ellis updated CASSANDRA-7441:
--------------------------------------
Priority: Minor (was: Critical)
Fix Version/s: (was: 2.0.7)
> Deleting an element from a list in UPDATE does not work with IF condition
> -------------------------------------------------------------------------
>
> Key: CASSANDRA-7441
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7441
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Reporter: Arvind Nithrakashyap
> Assignee: Sylvain Lebresne
> Priority: Minor
>
> When issuing a list deletion with an IF condition, that does not seem to work
> even when it says that the change was applied correctly.
> Here's a reproducible test case:
> {code}
> cqlsh:casstest> create table foo(id text, values list<int>, condition int,
> primary key(id));
> cqlsh:casstest> insert into foo(id, values, condition) values ('a', [1,2,3],
> 0);
> cqlsh:casstest> select * from foo;
> id | condition | values
> ----+-----------+-----------
> a | 0 | [1, 2, 3]
> (1 rows)
> cqlsh:casstest> update foo set values = values - [3] where id = 'a' IF
> condition = 0;
> [applied]
> -----------
> True
> cqlsh:casstest> select * from foo;
> id | condition | values
> ----+-----------+-----------
> a | 0 | [1, 2, 3]
> (1 rows)
> cqlsh:casstest> update foo set values = values - [3] where id = 'a';
> cqlsh:casstest> select * from foo;
> id | condition | values
> ----+-----------+--------
> a | 0 | [1, 2]
> (1 rows)
> {code}
> Addition seems to work though
> {code}
> cqlsh:casstest> update foo set values = values + [3] where id = 'a' IF
> condition = 0;
> [applied]
> -----------
> True
> cqlsh:casstest> select * from foo;
> id | condition | values
> ----+-----------+-----------
> a | 0 | [1, 2, 3]
> (1 rows)
> {code}
