AnyDAC does not provide a native Blackfish SQL Server driver, but you can use the AnyDAC/TDBX Bridge driver to connect to the Blackfish SQL Server. You should use the TDBX (DBX 4) Framework and the Blackfish SQL driver, which comes with CodeGear RadStudio 2007 or higher. 

To connect to the Blackfish SQL Server do the following:

• Open the file "C:\Documents and Settings\All Users\Documents\RAD Studio\dbExpress\dbxdrivers.ini". Find the [BlackfishSQL] section and modify it:
  • add "HostName=ServerName" ;
  • replace "Create=False" with "create=False".
• Create a connection definition, similar to this example. Please note that the "create" parameter must be specified using lower case characters.

DriverName=BlackfishSQL
DriverID=TDBX
hostname=127.0.0.1
port=2508
database=c:\addemo
create=True
user_name=sysdba
password=masterkey

• Drop a TADConnection component on the form.
• Set ADConnection1.ConnectionDefName to My_BSQL.
