Hi

Is there a way to create a boolean field in Interbase, and use it in Delphi
with .AsBoolean?
I now its possible to create new datatypes in Interbase, but I don 't now
how.

Tanks

Here's what I do

Make the interbase column a Word value. Then relate to it as a borland
pascal type Wordbool. This way the value is false when 0, but when true
could also hold a meaningful value. This duality becomes useful in a well
designed database.

Hope this helps...

Cheers

Anthony

Good solution, could come in handy even if the database does support
boolean.
