> -------------------------------------------------------------------------
>
> Key: TEIID-2936
> URL: https://issues.jboss.org/browse/TEIID-2936
> Project: Teiid
> Issue Type: Feature Request
> Components: Query Engine
> Affects Versions: 8.7
> Reporter: Mike Higgins
> Assignee: Steven Hawkins
> Fix For: 8.8
>
>
> When two 'in' criteria containing constant values on the same field are combined with an 'or', Teiid will combine the two into a single 'in' operation.
> Since Oracle (for example) has a 1000 item limit on the 'in' values, if the resulting combined list contains more than 1000 values, it can no longer be pushed down into Oracle for execution.
