FunkyKB: “Explicit vs implicit SQL joins” and other notes…

Stack Overflow: “Personally I prefer the join syntax as its makes it clearer that the tables are joined and how they are joined. Try compare larger SQL queries where you selecting from 8 different tables and you have lots of filtering in the where. By using join syntax you separate out the parts where the tables are joined, to the part where you are filtering the rows.”

“How do i write the literal "]]>" inside a CDATA section with it ending the section?”

Stack Overflow: “This ends up breaking the CDATA section in two parts, but it’s what you have to do…”


Issues like this should be more and more moot/antiquated for my needs as the .NET framework in general and LINQ to XML in particular provide facilities that make these “tricks” unnecessary.

MSDN: “There will still be a few cases where you may want to use the EXPLICIT mode (in order to generate CDATA sections or to use the !xmltext directive, for example), but the new functionality should make the “query from hell” a much less frequent encounter.”

“SQL Server Index Basics” “For composite indexes, take into consideration the order of the columns in the index definition. Columns that will be used in comparison expressions in the WHERE clause (such as WHERE FirstName = 'Charlie') should be listed first. Subsequent columns should be listed based on the uniqueness of their values, with the most unique listed first. ”
