Written by Michael Sansoterra
In this final installment of this DB2 for i coding series, I’ll discuss two items. First, I’ll examine a reason why a query that once performed well when it was first written might become lethargic as time passes. Second, I’ll discuss a way to potentially improve the performance of multi-row update statements. In the end, the lessons are how to avoid some common coding flaws that can take the wind out of your database sails.
