             Summary: Fix type inference when converting large IN clauses to semijoins
                 Key: CALCITE-824
                 URL: https://issues.apache.org/jira/browse/CALCITE-824
             Project: Calcite
          Issue Type: Bug
          Components: core
    Affects Versions: 1.1.0-incubating, 1.2.0-incubating, 1.3.0-incubating, 1.4.0-incubating
            Reporter: Josh Wills
            Assignee: Julian Hyde


I hit an issue where using an IN clause of int literals would work properly when compared against a BIGINT column when the IN clause had less than 20 values, but would fail when processing more than 20 values. I traced the issue to the way target row types are handled inside of the code that converts the IN clause into a semijoin.
