How to fix creation of table with reserved keywork (key)? - sql-server

Question

I use liquibase to initilize my h2 database for unit testing, but there is a problem with one table using "key" as name of column.
I tried "_key" as name, it works but the database (which I cannot change its schema) use "key" as a column name, so i have to put #Column("\"key\"") in my domain class. This works for SQL Server (production database) but doesn't for h2 (in memory db for testing)
In Liquibase xml:( for unit test)
<column name='_key' type="varchar(100)">
<constraints nullable="true" />
</column>
My domain:
#Column(name = "_key", length = 100)
//#Column(name = "\"key\"", length = 100)
private String key;
So I have to uncomment the first option and comment the second to make the unit test works and do the opposite to make the application work.
Using the
#Column(name = "\"key\"", length = 100)
with
<column name="key" type="varchar(100)"> or
<column name="\"key\"" type="varchar(100)"> or
<column name='"key"' type="varchar(100)">
returns an error:
Schema-validation: missing column [key] in table [displaymessages]
and the query that creates the table is:
CREATE TABLE PUBLIC.displaymessages (
id BIGINT AUTO_INCREMENT NOT NULL,
"'key'" VARCHAR(100),
value VARCHAR(1000),
type INT NOT NULL,
createdon date NOT NULL,
modifiedon date,
isdeleted INT NOT NULL,
CONSTRAINT PK_DISPLAYMESSAGES PRIMARY KEY (id)
)

On the changeset that creates the table/column, you can add an attribute objectQuotingStrategy with the value QUOTE_ALL_OBJECTS, as shown in the example below:
<changeSet author="Sir Cuke Umber" id="1::addTable::labelA" labels="AAA" objectQuotingStrategy="QUOTE_ALL_OBJECTS">
<createTable tableName="LABELA">
<column name="message" type="TEXT">
<constraints nullable="true" primaryKey="false" unique="false"/>
</column>
</createTable>
</changeSet>
This attribute can also be added at the root changelog level if you want every identifier to be quoted.
