Flink Jira Bot updated FLINK-11221:
-----------------------------------
Labels: auto-unassigned stale-major (was: auto-unassigned)
I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help
the community manage its development. I see this issues has been marked as
Major but is unassigned and neither itself nor its Sub-Tasks have been updated
for 30 days. I have gone ahead and added a "stale-major" to the issue". If this
ticket is a Major, please either assign yourself or give an update. Afterwards,
please remove the label or in 7 days the issue will be deprioritized.
> Support delimited identifiers in TableAPI
> -----------------------------------------
>
> Key: FLINK-11221
> URL: https://issues.apache.org/jira/browse/FLINK-11221
> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / API
> Reporter: Hequn Cheng
> Priority: Major
> Labels: auto-unassigned, stale-major
>
> There are two kinds of identifiers in SQL: regular identifiers and delimited
> identifiers. Different from regular identifiers, delimited identifiers are
> identifiers enclosed in double backticks(``), double quotation marks (") or
> brackets ([ ]).
> Currently, delimited identifiers in double backticks have been supported in
> Flink SQL(thanks to Calcite). In Calcite, delimited identifiers may contain
> virtually any character, including spaces and other punctuation. With
> delimited identifiers, we can name some special identifiers such as `a-a`
> which may be an essential requirement.
> However, delimited identifiers are not supported in TableApi. It would be
> nice if we support it in TableApi.
> Any suggestions are welcomed! Thank you.
