> Provide alias for whole records in Table API
> --------------------------------------------

> Key: FLINK-9617
> URL: https://issues.apache.org/jira/browse/FLINK-9617
> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / API
> Affects Versions: 1.5.0
> Reporter: Piotr Nowojski
> Assignee: Ashwin Sinha
> Priority: Major
> Labels: stale-assigned
>
> In SQL we can provide an alias for whole table to avoid column name
> collisions between two tables. For example:
> {code:java}
> SELECT
> SUM(o.amount * r.rate)
> FROM
> Orders AS o,
> Rates AS r
> WHERE r.currency = o.currency{code}
> However that's not possible in table API. In Table API user have to provide
> aliases for all of the columns, which can be annoying especially if table
> consists of tens or even hundred of columns
> For example I would expect some feature like this:
> {code:java}
> val result = orders.as('o)
> .join(rates(`o.rowtime).as('r), "o.currency = r.currency")
> .select("SUM(o.amount * r.rate) AS amount")
> {code}
> where \{{rates}} is a TableFunction.
