If the actual names are like what you have above, then you could
use:

  <!--#in "_['1.2'].sql_method()"--> ...

That is, you acquire '1.2' and invole it's 'sql_method' method.

If you had names like:

 A
 |_A_A
 |   |_A_A_A
 |       |_obj
 |_A_B
     |_sql_meth

it would be a little prettier:

  <!--#in "A_B.sql_method()"--> ...
