2.1.210: Replacement of ALIAS_COLUMN_NAME=true?

[t603]

Hello, I used to use ALIAS_COLUMN_NAME=true  in JDBC URL in H2 1.x version permanently. It is dropped now in 2.x. I would like to use it in 

create linked table "linked_MY_TABLE" (..., ..., ..., ..., '(select trim(MY_COLUMN) as "COL_A" from "MY_TABLE")'); 

So I wold like to get column "MY_COLUMN" from "linked_MY_TABLE". How can I achieve it in H2 2.1.x version? Using some mode like Db2 is not welcome, it has other unwelcome effects. 

Thank You in advance for help, Stepan
