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

             Summary: How to check  sql is right before to execute accross API
                 Key: FLINK-22538
                 URL: https://issues.apache.org/jira/browse/FLINK-22538
             Project: Flink
          Issue Type: Improvement
          Components: Table SQL / API
    Affects Versions: 1.12.2
            Reporter: ranqiqiang


If user  writes  some flink-sql include (source    query  ....  sink ) , then how to check the sql is right ?  

such as 
 # the field nums is equals ?
 # the field type is match ?
 # udf is exist ?

Because user  executes sql will be wrong !  and found many errors, It's to late .

I just want to check the sql-errors out before to execute sql!

 

Now,how to get the check api or method?

I think it's  a usefull  idea !

thanks
