IV.2.2.1. Creating user-defined stored procedures
Creating user-defined stored procedures is a skill that most database administrators need in day-to-day operations. If you say you can work with SQL Server, you're expected to know how to create basic stored procedures.
Darril recently went to a job interview for an application developer where this was given as one of the few questions the company asked: "Our applications frequently access databases, and we commonly create stored procedures to access the databases. Tell us about your knowledge related to creating stored procedures."
Knowing how to create and use stored procedures is often considered a core skill requirement. Your knowledge and skill set in this area may be the difference between getting a job offer or not. (By the way, Darril did get the job offer based on that interview.)
When you first start creating stored procedures, ...
