Hello. Syntax of comments on columns in their definitions exists mostly for a some limited compatibility with MySQL, but it was included into documentation for some bad historic reason. Actually it shouldn't be documented and should be accepted only in the related compatibility modes, but what's done is done.
Comments on database objects aren't a part of the SQL Standard, so they are not portable across DBMS. Native support in H2 is provided by a separate COMMENT ON command and there is no intention to add some random alternative grammar for this purpose, unless some grammar will be standardized or at least will be widely supported by multiple DBMS. Syntax that you found in the parser is internal only, it should never be used by users of H2. It is intentionally not documented. -- You received this message because you are subscribed to the Google Groups "H2 Database" group.
