An Introduction to SQL for Librarians
By Ruth Kitchen Tillman
Why are Librarians Suited to SQL?
Because querying information is what we do. You’ve thought “ok this is what I want, now where do I go to get it and what should I put into the fields?” In many cases we’re already doing mediated queries which are functionally indistinguishable from SQL. When you’re saying that you want to search for Article from a database where a Title is “Name of the title,” what you’re doing is essentially the same as writing a SQL query. Reports used to get data from or update data in your ILS use the same type of querying.
