I would like to react on the environment in my Mapper XML file.
The environment is set into the SqlSessionFactoryBuilder

new SqlSessionFactoryBuilder().build(is, environment)

Now I want to use this environment variable in my if condition.
I tried this:

    SELECT 
    <if test="_environment == 'test'">
        TEST.
    </if>
    <if test="_environment == 'prod'">
        PROD.
    </if>
    MY_TABLE

But this is not working, the result is SELECT MY_TABLE without any if condition.
I need this because I need different prefixes in my statement.

Who can helps me out?
