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

             Summary: SQL ALTER TABLE ADD COLUMN to support IF NOT EXISTS
                 Key: IGNITE-27809
                 URL: https://issues.apache.org/jira/browse/IGNITE-27809
             Project: Ignite
          Issue Type: New Feature
            Reporter: Ivan Zlenko


We should support following syntax:

{{alter table tableName add [column] if not exists column_name int;}}
 * if tableName has no column yet, it will create

 * if tableName has the column already, no exception is thrown

PS. We can extend this also to {{DROP COLUMN IF EXISTS}} functionality.
