In this Microsoft Access tutorial I will show you how to optimize your code for faster lookups by comparing traditional DLookup with a more efficient recordset method using SQL and dbOpenSnapshot. We will build a sample button to implement each technique, measure execution times, discuss indexing for speed, and explain why recordsets are generally faster and more scalable than repeated DLookup calls. This is part 2.
Silver Members & up get access to an Extended Cut of this video. In the extended cut, we will build several faster custom functions using record sets instead of DLookup and DCount, including MyDLookup, MyDCount, MyDExists, and MyDValueList. I will show you how to make each of these, and demonstrate how MyDValueList can return multiple fields as an array from a single call.
