Description
Returns a field definition object given its field name.
Call FieldByName to obtain information about a particular field definition object. Specify the name of the field as the value of the Name parameter. If Name is not found, FieldByName raises an EDatabaseError exception with the error message "Field not found".
Note: FieldByName differs from the Find method only when the named field definition is not in the list. When the field definition is not found, FieldByName raises an exception, while Find returns nil (Delphi) or NULL (C++).
