Hello,

When I set an integer value > 255 by SQLDataSet.ParamByName('FIELDNAME').value, I Have the error "Feature not implemented".

No problem if I use SQLDataSet.ParamByName('FIELDNAME').asInteger
No problem if integer value <256

Test done under DEX5 DBXpida40.dll 4.6.9 on WIN7-64 with Firebird 2.5

Demo attached :http://www.sendbox.fr/ff877a28d6a56253/ ... _FB225.zip

Thank you

This behavior is related not to dbExpress driver for InterBase & Firebird, but to dbExpress technologies. Unfortunately, we can't affect it. You can make this sure using the Firebird driver that will return the same error.

Ok,

I replaced all SQLDataSet.ParamByName('FIELDNAME').value by SQLDataSet.ParamByName('FIELDNAME').AsInteger and no problem

Thank you

It is good to see that the problem has been solved. Feel free to contact us if you have any further questions about dbExpress driver for InterBase & Firebird.
