Acronym for either Structured or Simple Query Language - noone is quite certain. Also resolved as Stupid Query Language.
It's a set-centric ProgrammingLanguage in which statements are excuted over a Schema of relations (tables) and return a set of results.
AddToMe: Someone should explain the general syntax of SQL here.
SELECT cols FROM tables WHERE condition UPDATE table SET column=value WHERE condition DELETE FROM table WHERE condition INSERT INTO table (columns) VALUES (values)
