Cannot read ntext field

[eugene]

I get the following message
EAssertionFailed with message 'Unknown data type (30)(D:\Projects\Delphi\Dbx\Source\dbexp.pas, line 1930)'

the query is
var SQLQuery:TSQLQuery;
...
SQLQuery.add('
SELECT O.ID,o.name,o.content,T.* FROM WARNINGMODELS O LEFT JOIN WARNINGMODELTAGFORMATS T ON
O.ID=T.MODELID ORDER BY O.ID.);

SQLQuery.Open;

o.content is ntext.

I use Delphi 2006
Version 3.10.8.0 of dbexpsda30.dll

Thank you
