[teiid-issues] [JBoss JIRA] (TEIID-5060) Infinispan Hotrod Translator UPDATE on primary key column

[Ramesh Reddy (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-5060?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13463631#comment-13463631 ] 

Ramesh Reddy commented on TEIID-5060:
-------------------------------------

You are comparing the StringKey with an integer value. The latest master code fails with a resolution error which is correct. I would think any implicit conversions will be done before it reaches the translator layer. May be this check is not there in 6.4. [~shawkins] should know.

> UPDATE query where the PRIMARY KEY of the table is being changed succeeds, returns update count of corresponding rows, but the changes don't get promoted to actual cache.
> Consider
> {code:sql|title=UPDATE query}
> UPDATE SmallA SET StringKey = 100 WHERE IntKey > 25
> {code}
> where StringKey is set as PRIMARY KEY and 6 rows fulfill the filter on IntKey>25.
> When this UPDATE is performed, returned number of rows update is 6, but the contents of the cache don't change.
> There are several applicable resolutions:
> # There should be error thrown by Teiid, that this is not allowed operation
> # There should be update count 0 returned
> # There should be change in JDG cache, effectively squashing the 6 rows into single one
> # There should be error thrown by Teiid, that there is duplicate PK value (this is not something Teiid usually enforces)
