public function TIndexDefs.FindIndexForFields(

const Fields: string

):TIndexDef;

Function result

TIndexDef instance with fieldlist matching Fields

Description

FindIndexForFields searches in the list of indexes for an index whose TIndexDef.Fields property matches the list of fields in Fields. If it finds an index definition, then it returns the found instance.

Errors

If no matching definition is found, an exception is raised. This is different from other Find functionality, where Find usually returns Nil if nothing is found.
