> Align Calcite's and Flink's SYMBOL types
> ----------------------------------------
>
> Key: FLINK-17151
> URL: https://issues.apache.org/jira/browse/FLINK-17151
> Project: Flink
> Issue Type: Sub-task
> Components: Table SQL / API
> Reporter: Dawid Wysakowicz
> Priority: Major
>
> Flink's `SymbolType` stores the class of the symbol. Calcite does not. When
> converting from Flink's to Calcite's type we are loosing that information. We
> should either remove that from the Flink's type or add it to Calcite's.
> I am in favor of removing it from the {{SymbolType}}. This type is a pseudo
> type which can be used only for literals. The symbol class is already part of
> the corresponding value, therefore it is a redundant information in the type
> itself.
