Description

Searches for a specified field in the dataset.

Call FindField to determine if a specified field component exists in a dataset. FieldName is the name of the field for which to search. This name can be the the name of a simple field, the name of a subfield of an object field that has been qualified by the parent field's name, or the name of an aggregated field.

If FindField finds a field with a matching name, it returns the TField component for the specified field. Otherwise it returns nil (Delphi) or NULL (C++).

FindField is the same as the FieldByName method, except that it returns nil (Delphi) or NULL (C++) rather than raising an exception when the field is not found.
