------------------------------------
Summary: Allow variables for column names in Scala Table API
Key: FLINK-18699
URL: https://issues.apache.org/jira/browse/FLINK-18699
Project: Flink
Issue Type: Improvement
Components: Table SQL / API
Reporter: Timo Walther
Assignee: Timo Walther
User have reported that the Scala API lacks a way to reference columns via a
name that is stored in a variable. String interpolation is inconvenient in this
case:
We should allow this also in Scala:
{code}
tab.select($(keyVar), $(valueVar))
{code}
