[jira] [Comment Edited] (FLINK-22315) Support ADD column/constraint/watermark for ALTER TABLE statement

    [ https://issues.apache.org/jira/browse/FLINK-22315?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17429247#comment-17429247 ]

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

'alter table add constraint' syntax is availiable [here|https://github.com/apache/flink/blob/fe59485be2ae2b576cbd252e78cc6f0d36ce090b/flink-table/flink-sql-parser/src/main/codegen/includes/parserImpls.ftl#L534] .
So, we just support extra 'ADD column / watermark'  for ALTER TABLE statement, IMO.

There is a minor question about 'ADD column ' syntax. Should the syntax  support adding multiple columns at one time ?
