Actually most users of different backend db will be familiar with the
SQL version of that backend. What users need are two things: a connector
between Base and the backend and instructions on connecting to that backend.
If only it were possible to somehow communicate with people from the various back-end projects
perhaps even ask them to write-up a brief sub-chapter on how to use their back-end in conjunction
with Base. I wonder if any of them know anything about the use of Sql in their projects.
The BoD want to sit&wait rather than be pro-active about this sort of collaboration.
SQL is the standard query language for relational databases so if one
writes queries for a relational database one should know a dialect of
SQL. SQL has a published international standard that db developers
follow. The problem is that each developer will add non-standard
extensions for their db making the resulting code possibly not portable.
An example is loading/exporting data from a file into a database is
defined in the SQL specifications so each db has its extension to do the
same thing. Each extension needs the same information but has a
different syntax for the command.

Did you try with another database as a backend? I like postgres as a
backend a lot.
I am writing a chapter of the Base Guide that includes using SQL
in the Query Design dialog. Chapter 8 of the Base Guides covers using
HSQLDB 2.2.8, MySQL, and PostgreSQL as back ends. So, I am not there
quite yet. It seems that because Base uses HSQLDB 1.8, it does not
conform with the user guide for the database engine it uses.
When I get to that point, I will need to research how each of
these backends use SQL.

On this simple level I would consider HSQLDB as free of bugs whereas the
primitive Base parser fails in many different ways.
Did you try the direct SQL mode (SQL view, menu:Edit>Run SQL directly)? If
you get reasonable result in direct mode, it is one of many bugs in the
Base's SQL parser.

That is the one thing that I forgot to mention: I get the same
message when using direct SQL mode. I even tried using Tools > SQL, but
with the same message.
