[teiid-issues] [JBoss JIRA] (TEIID-3474) Inconsistent results of RIGHT function for different datasources

[Juraj Duráni (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-3474?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13067671#comment-13067671 ] 

Juraj Duráni commented on TEIID-3474:
-------------------------------------

DB2 - If you use "char(integerValue)" the result will have fixed length. That is expected behavior according to DB2 documentation [1]. But function "varchar(integerValue)" returns "usable" result [2].

> The RIGHT function returns different results for different datasources. Some of those results are inconsistent with definition of the RIGHT(x,y) function.
