---------------------------------
[~atri] Thank you for your hard work. Can we build a PR first
> Support INSERT INTO specific columns
> ------------------------------------
>
> Key: FLINK-18726
> URL: https://issues.apache.org/jira/browse/FLINK-18726
> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / Planner
> Reporter: Caizhi Weng
> Assignee: Atri Sharma
> Priority: Major
>
> Currently Flink only supports insert into a table without specifying columns,
> but most database systems support insert into specific columns by
> {code:sql}
> INSERT INTO table_name(column1, column2, ...) ...
> {code}
> The columns not specified will be filled with default values or {{NULL}} if
> no default value is given when creating the table.
> As Flink currently does not support default values when creating tables, we
> can fill the unspecified columns with {{NULL}} and throw exceptions if there
> are columns with {{NOT NULL}} constraints.
