> Key: CAY-2137
> URL: https://issues.apache.org/jira/browse/CAY-2137
> Project: Cayenne
> Issue Type: Improvement
> Components: Core Library
> Affects Versions: 4.0.M4
> Reporter: Hugi Thordarson
> Assignee: Nikita Timofeev
> Priority: Minor
>
> When Cayenne generates SQL for EJBQLQueries that use relationships with
> multiple joins, it puts commas between the join conditions in the resulting
> SQL-statement. This does not work with some databases (at least Informix)
> which wants “AND” between joins.
> For example, this doesn’t work:
> …FROM bok_invoice_line t0 INNER JOIN bok_invoice t1 ON (t0.company =
> t1.company, t0.year = t1.year)
> While this works:
> …FROM bok_invoice_line t0 INNER JOIN bok_invoice t1 ON (t0.company =
> t1.company AND t0.year = t1.year)
> If the same expression is used in a regular SelectQuery, Cayenne puts “AND”
> between the joins rather than commas and everything will work fine. This
> issue is for aligning the behaviour of these two to make it more compatible
> (use AND when generating SQL from EJBQL).
