Transfer DBase 7 tables to Interbase....
Jan
The problem is that most of the tables uses 1 or more boolean - fields.
Now, Interbase don 't support boolean, but the application use this
boolean-fields
very frequent.
Is there a field-type in Interbase that I can read and write as AsBoolean in
a Delphi-application?
Thanks.....

replace the boolean fields to a integer type and use
0 and 1.

may be you should just create some domain in your interbase db so it anderstands
boolean the same way it does for db7

Try to use IB Objects. (http://www.ibobjects.com). This excellent
product may emulate boolean columns by defining "true" and "false"
values for any domain. As example, you can define domain "tbool" as
integer, and <TIBODatabase.ColumntAttributes='boolean=tbool=1,0'>.
After this declaration, fields declared by "tbool" will be created as
TBooleanField.
