That's a great SQL tuning presentation, but I don't follow what he says in slide #91:



"No WHERE clause with an ORDER BY"
Often a screen will return rows with a predefined order, e.g., ORDER BY NAME. The user is expected to enter a NAME or part of a name, NAME=SMI. If the user presses Enter for the query without entering a name, all table rows must be sorted. So always have a WHERE NAME > CHR(1).

What does the extra WHERE clause do for you?
