-KeyColumn
-KeyColumn specifies the name of the key field which should be used for a database action. This tag can be used in concert with the -KeyValue command tag to identify a particular record for a -Delete, -Duplicate, -Image, or -Update action. Synonym is -KeyField.
The value specified for this command tag can be retrieved using the [KeyField_Name] tag.
FileMaker Note: The -KeyField for FileMaker Pro databases is ignored. The -KeyValue always specifies the value for the implicit Record ID.
