Correct!
By using the Locate method we can look for values of one or more fields, passed in a variant array. Lookup does not move the cursor to the matching row, it only returns values from it. The ADO datasets Seek method uses an index when performing a search. If you don't specify an index and you are working with an Access database, the database engine will use the primary key index.
