Speed Up Code & Forms with This Simple Technique

In this Microsoft Access tutorial I will show you how to speed up your record lookups by using a method faster than DLookup, especially in performance-critical situations like OnCurrent events and looping code. We will compare DLookup with direct SQL queries and recordset techniques, test performance against large tables, and discuss when to use each approach for optimal results. This is for advanced users familiar with DLookup, NZ, VBA, recordsets, and basic SQL.
