Subject [jira] [Commented] (CASSANDRA-11397) LIKE query on clustering column index returns incorrect results
Date Wed, 23 Mar 2016 19:22:25 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-11397?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15208987#comment-15208987

Jordan West commented on CASSANDRA-11397:
-----------------------------------------

[~beobal] the patch looks good and i've confirmed your fix locally. One small piece of feedback:
since you fixed things to return a {{ClusteringIndexSliceFilter}} I don't think the {{isLike}}
check in {{PrimaryKeyRestrictionSet#appendTo}} is necessary anymore (i've removed it locally
without issue).

> The way that {{ClusteringIndexFilter}} and {{RowFilter}} are constructed when a {{LIKE}}
restriction on a clustering column is present is incorrect. For example:
> {code}
> cqlsh> create table ks.t1 (k text, c1 text, c2 text, c3 text, v text, primary key
(k,c1,c2,c3));
> cqlsh> create custom index on ks.t1(c2) using 'org.apache.cassandra.index.sasi.SASIIndex';
> cqlsh> select * from ks.t1;
>  k | c1 | c2 | c3 | v
> ---+----+----+----+-----
>  a | ba | ca | da | val
>  a | bb | cb | db | val
>  a | bc | cc | dc | val
> (3 rows)
>  
> cqlsh> select * from ks.t1 where c1 = 'ba' and c3 = 'da' and c2 LIKE 'c%' ALLOW FILTERING;
>  k | c1 | c2 | c3 | v
> ---+----+----+----+---
> (0 rows)
> {code}
