[jira] [Updated] (CALCITE-2926) IN operator type validation failure
[ https://issues.apache.org/jira/browse/CALCITE-2926?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Will Yu updated CALCITE-2926:
-----------------------------
Priority: Major (was: Blocker)
> 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
> Priority: Major
>
> 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.
