I talked with Dmitry Yemanov about this. He says that it should work,
and if it doesn't, he would like to have a look. I found that the same
exception I get in following statements:

SELECT * FROM rdb$database WHERE upper(?) = ?
SELECT * FROM rdb$database WHERE ascii_val(upper(?)) = 65

However, without upper(...) these statements work. If you have
reproducable test case, please send it to me or to Dmitry directly.
