You have four table options: normal tables, local temporary tables, global temporary tables and table variables. I'll discuss the differences between using temporary tables in SQL Server versus table variables.

These are the low hanging fruit of SQL Server performance – they are easy to do and often have a substantial impact. Doing these won’t guarantee lightening fast performance, but it won’t be slow either. Create a primary key on each table you create and unless you are really knowledgeable enough to...
