I am in the process of migrating an "old" tool from using ibx
components to uib components.

When I use the same database (FB 2.0) and script with the ibx
components, everything's fine. When using uib components I get this
error when I try to add some column to an existing table:

ALTER TABLE TBLDFUEDATEIAUSWAHL ADD MANERFDATUM DATE

Dynamic SQL Error
SQL error code = -817
Metadata update statement is not allowed by the current database SQL
dialect 1
The insert, update, delete, ddl or authorization statement cannot
be executed because the transaction is inquiry only
Error Code: 249

Can anybody explain this error? Do I have to adjust some transaction
params/options? If so, which?
