Hi,

I am trying to execute this statement on Firebird:

SELECT count(1)
FROM
(SELECT ID, CLIENT_TYPE, SERIAL_NO, ENABLED
FROM BUSINESS_TYPES)
ESTCOUNT

It gives me the following error:
Dynamic SQL Error
SQL error code = -104
Token unknown - line 3, char 2

There is no information that such query will not work on FireBird
database.

Could you help me with some information on that issue?
