--------------------------------
Summary: IN operator type validation failure
Key: CALCITE-2926
URL: https://issues.apache.org/jira/browse/CALCITE-2926
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.18.0
Reporter: Will Yu
There are two columns in my table. Column A's type is VARCHAR while column B's
type is VARCHAR ARRAY.
When validating the SQL call `A IN B` the validation failed.
The root cause seems to be in checkTypes functions in SqlInOperator.
# Not sure whether UNORDERED comparator is a good candidate because IN
operands should have order.
# During being checked in the checker, `canConvertStringInCompare` will give a
`false` when family is ARRAY and cause this failure.
