DIALECT statement. A syntax error - it should not be there. The fact
that the metadata script is trying to set the dialect to 3 indicates
that the DATABASE is dialect 3. In order for the script to create the
metadata, it needs to set the CLIENT dialect to 3, to match the
DATABASE dialect. That is what that statement was trying to do. If
you intend to go by this route, it will be necessary to open the

Use your preferred tool(s) to get the database header information.
The details you need are: ODS version, database dialect and default
character set.
Using Firebird's command-line tools:
gstat -h path\to\database will return the first two.
isql path\to\database -user sysdba -password masterkey
will return the default character set.
A database created or restored under Firebird 1.5 should have an ODS
of 10.1. When you restore it under v.2.1 it should have an ODS of
11.1.
IBExpert probably has a tab that shows all of this information in one
place.
You do not need to pump the data UNLESS (one or both):
- the database dialect is 1 and you want it to be 3 (apparently not
necessary in this case)
- the default character set is NONE and you know that it is actually
in a directly supported character set. In that case, you would need
to pump the data into an empty database with the desired default
character if you wanted to realise the true charset of the text data.
Otherwise, you need to:
1. Back up the v.1.5 database using the gbak.exe from the V.1.5
distribution. If you no longer have it, you can download the v.1.5.6
zip kit from website and extract the program.
NOTE, you must make this backup using the v.1.5 gbak.exe. You can run
this program under your v.2.1.7 installation. Either (a) temporarily
reanme gbak.exe in your v.2.1.7 installation and copy the v.1.5
version to the \bin directory; or you can run the v.1.5 gbak.exe from
a different location.
2. Restore the backup file using the **v.2.1.7 version*** of gbak.exe.
Regarding the notes above about database dialect, you might run into
some transliteration problems. I won't go into that here; but you
can read up about in the v.2.1.7 release notes. Gbak has some switches
you can use.

Firebird. It is not used for constructing/reconstructing data or

new lexicon to learn.
Database Definition Language (DDL) is used for construction and

Database Manipulation Language (DML) is used for creating, modifying,
deleting and querying data.
In Firebird, DDL and DML are highly compliant with standards.
