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

             Summary: 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


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.
