Piotr Bojko commented on CALCITE-2009:
--------------------------------------
I've discovered that when launching the followinf query alone - all works ok:
{code:sql}
SELECT JI.ID, JI.SUMMARY, JI.PROJECT
FROM INTERNAL.JIRAISSUE as JI
WHERE JI.ID IN (SELECT EAI.ID FROM EXPLICIT_ALLOWED_ISSUES AS EAI)
OR (JI.PROJECT IN (SELECT AP.ID FROM ALLOWED_PROJECTS AS AP))
{code}
but if the same query is used as a view - then results are not the same (empty
results for select * from issues)
{code:javascript}
{
"name": "ISSUES",
"type": "view",
"sql": [
"SELECT JI.ID, JI.SUMMARY,
JI.PROJECT ",
"FROM INTERNAL.JIRAISSUE as JI
",
"WHERE JI.ID IN (SELECT EAI.ID
FROM EXPLICIT_ALLOWED_ISSUES AS EAI) ",
"OR (JI.PROJECT IN (SELECT
AP.ID FROM ALLOWED_PROJECTS AS AP))"
]
}
{code}

> Where INTERNAL schema points to JDBC native JIRA Schema (through my custom
> factory, but it only wraps passing datasource instead of user/password/url to
> db) and JIRA schema has one view and two tables (factories generate java data
> wrapped in AbstractQueryableTable)
> When running "SELECT * FROM ISSUES" all works.
> But when changing the view from UNION construction to OR - engine provides no
> results:
