[teiid-issues] [JBoss JIRA] (TEIID-5459) Support for large counts/ranks

[Steven Hawkins (Jira)]

     [ https://issues.jboss.org/browse/TEIID-5459?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Steven Hawkins resolved TEIID-5459.
-----------------------------------
    Resolution: Done


The initial work focuses solely on the functions with integer return values - rank, dense_rank, and row_number.  Additional work would be needed to allow the inner working of cume_dist and percent_rank to use long instead of integer - that can be worked later if it becomes an issue.  COUNT_BIG was introduced, but is generally pushed as COUNT instead.

> Most databases implement analytical ranks/row_number as returning bigint - regardless of what type count returns.  MS SQL introduced BIG_COUNT, and Postgresql switched everything to bigint in 7.2.
