I think it will be great to implement this, looking forward the PR :)

> Key: FLINK-3891
> URL: https://issues.apache.org/jira/browse/FLINK-3891
> Project: Flink
> Issue Type: Improvement
> Components: Table API
> Reporter: Timo Walther
> Assignee: Timo Walther
> Priority: Minor
>
> In order to make working with the Table API easier. It would be great to have
> a class that contains the supported types.
> Such that an expression could look like:
> {code}
> .select(42.cast(TableType.INT), 43.cast(TableType.DECIMAL))
> {code}
> The constants would map to the original TypeInformation object (in
> BasicTypeInfo, SqlTimeTypeInfo, etc.).
