>          Components: Table SQL / Planner
>            Reporter: Caizhi Weng
>            Assignee: Atri Sharma

> 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.
