------------------------------------

             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.
