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

             Summary: No API for execute insert into statement 
                 Key: FLINK-15395
                 URL: https://issues.apache.org/jira/browse/FLINK-15395
             Project: Flink
          Issue Type: Bug
          Components: Table SQL / API
    Affects Versions: 1.10.0
            Reporter: Jeff Zhang


IIUC, TableEnv#sqlUpdate is used for DDL while TableEnv#sqlQuery is used for 
DML. Unfortunately, it seems `insert into` is a special case that no simple api 
can be used for it. 
The code of implementing `insert into` in sql-client is pretty complex, it 
would be nice to have one simple api for executing `insert into`
