Basic SQL Cheat Sheet

By | August 27, 2018

SQL (Structured Query Language) was initially developed at IBM by Donald D. Chamberlin and Raymond F. Boyce after learning about the relational model from Ted Codd in the early 1970s. This version, initially called SEQUEL(Structured English Query Language), was designed to manipulate and retrieve data stored in IBM’s original quasi-relational database management system, System R, which a group at IBM San Jose Research Laboratory had developed during the 1970s.

SQL can be used to create database and database entities(table, view, stored procedure, function etc), manipulate database entities (table, views, stored procedure, function etc), store and retrieve data.

Here is a small cheat sheet which can be used by a SQL programmer to revise SQL basics.

    I am really loving the theme/design of your website. Do you ever run into any browser compatibility issues? A couple of my blog readers have complained about my website not working correctly in Explorer but looks great in Firefox. Do you have any ideas to help fix this problem?|

    Hey there this is kinda of off topic but I was wondering if blogs use WYSIWYG editors or if you have to manually code with HTML. I’m starting a blog soon but have no coding knowledge so I wanted to get guidance from someone with experience. Any help would be greatly appreciated!|

    I’ve been surfing online more than three hours nowadays, yet I never discovered any attention-grabbing article like yours. It is lovely value sufficient for me. Personally, if all website owners and bloggers made excellent content as you probably did, the web will likely be much more useful than ever before.|
