It looks as if the tool you used to define your table has imposed
case-sensitivity on your identifiers. If so, you will have to use
double-quotes around all of your identifiers and also ensure that they are
correct for case. For example:

SELECT "Name", "Type" FROM MyTable

This little "feature" was introduced in IB 6 as an option, to enable people
to use illegal words as identifiers (like your use of the reserved word
TYPE as a column identifier).

This isn't a matter of IBO filters not working - it's a matter of the way
your metadata have been set up.

Old IB hands have long ago learned to avoid illegal words as identifiers
and eschew quoted identifiers (which are optional) with a passion....yet C
programmers (including Geoff) will argue just as passionately FOR the
quoted identifiers - so it gets down to preference ultimately...
