------------------------------------
Summary: support variable substitution
Key: FLINK-17377
URL: https://issues.apache.org/jira/browse/FLINK-17377
Project: Flink
Issue Type: New Feature
Components: Table SQL / API, Table SQL / Client
Affects Versions: 1.10.0
Reporter: Guangbin Zhu
FlinkSQL does not support variable substitution like hive.
{code:java}
SET k1=v1;
Select * from table where key=${k1}{code}
This is a common and great useful feature that Flink should support.
