[jira] [Created] (IGNITE-10471) SQL: Alter table to add column
sytax doesn't support the user types but drop column can drop such fields
Andrey Aleksandrov created IGNITE-10471:
-------------------------------------------
Summary: SQL: Alter table to add column sytax doesn't support the user types but drop column can drop such fields
Key: IGNITE-10471
URL: https://issues.apache.org/jira/browse/IGNITE-10471
Project: Ignite
Issue Type: Improvement
Components: sql
Affects Versions: 2.6
Reporter: Andrey Aleksandrov
Fix For: 2.8
Looks like ALTER COLUMN commands could be used only on a subset of supported types (that could be used in CREATE TABLE syntax):
[https://apacheignite-sql.readme.io/docs/data-types]
But using query entities we can provide to use a field that has user types.
This fields can be used in
ALTER TABLE CACHE_NAME DROP COLUMN COLUMN_NAME
But it can't be used as next:
ALTER TABLE CACHE_NAME ADD COLUMN COLUMN_NAME 'type'
Where type is a user's one.
Possible we should think about supporting POJO and enums.
