OMG, I should thank Mark for the brilliant syntax and SET for the tips to detect field position.

Thanks a lot SET, I wrote that post w/o preparation & now I see  the syntax I wrote was awful. Your syntax meets my expectation, probably you would like to help us (I'm sure not just me need that feature) posting request in right site :-)

Your tips to detect field position is also very helpful for now, thanks again.

You don’t have to count field position, just issue

select rdb$field_position+1
from rdb$relation_fields
where rdb$relation_name = :TableName
and rdb$field_name = :FieldName

to find where the field currently is placed. Of course, you would have to know whether or not the field you wanted to move should be moved forward or backward and adjust by 1 if necessary, but that is just a minor adjustment.

HTH,
