             Summary: Transitive Inference on Join Condition is not type safe
                 Key: CALCITE-1007
                 URL: https://issues.apache.org/jira/browse/CALCITE-1007
             Project: Calcite
          Issue Type: Bug
          Components: core
    Affects Versions: 1.5.0
            Reporter: Laljo John Pullokkaran
            Assignee: Laljo John Pullokkaran


select * from (select 1 as x from t1) t1 join (select stroll as x from t2)t2 
join t1.x=t2.x;

While transferring x=1 from t1 to t2, we don't use the correct type for 'x' on 
t2.
This could result in data correctness.
