It's something that confuses a lot of people, even though SQL has been a big part of the tech industry for decades. Should you spell it out as “S-Q-L” or just say “sequel”? Let's dig into this debate and see if we can figure it out. </em></p> <p>SQL has been around for decades and <a href="/blog/what-is-sql-used-for/">supports a many billion dollar market</a>. However, many people still struggle with just how to pronounce the term SQL. Is it "S.Q.L" ['?s kju? '?l] or is it "sequel" ['si?kw?l]?</p> <p>The pronunciation of SQL remains a topic of lively discussion among professionals and enthusiasts alike. Are you in the “S.Q.L” camp, articulating each letter, or do you prefer the smoother sounding “sequel”? It's interesting how this simple question can show people's personal and professional preferences, and there are so many different opinions out there.</p> <p>And if you are here to learn SQL, check out our interactive <a href="https://learnsql.com/course/sql-queries/">SQL Basics</a> course.

Where it All Started</h2> <p>Let's start at the beginning.</p> <div class="rek-banner " style="" banner-url="/"></div> <p><a href="https://learnsql.com/blog/sql-database/">Relational databases</a> came into existence with E.F. Codd's 1970 publication "A Relational Model of Data for Large Shared Data Banks." While Codd's ideas were remarkable for the time, in San Jose, California, two colleagues named Donald D. Chamberlin and Raymond F. Boyce were developing SQUARE (Specifying Queries As Relational Expressions) – a query language.</p> <p>By 1974 they published the query language SEQUEL (Structured English Query Language) based on SQUARE. Unfortunately, due to trademark violations on the acronym SEQUEL, which was already registered by the Hawker Siddeley aircraft company, the name was changed to Structured Query Language and abbreviated as SQL. You can read more about the history of SQL in <a href="https://learnsql.com/blog/history-of-sql/">an article on our blog</a>.</p> <p>In 1979, not long after IBM's prototype, the first SQL product, ORACLE V2, was released by Relational Software (which was later renamed to Oracle Corporation). Within weeks of the Oracle V2 release, IBM released its first offering, System R, using a new query language called SEQUEL developed by IBM. This was followed by SQL/DS in 1981, and finally DB2 1983, which remains IBM's flagship RDMS product to this day.</p> <p style="text-align: center"> <picture><source srcset="sql-history.webp" type="image/webp"><img src="sql-history.png" alt="sql-sequel" class="" loading="lazy" width="735" height="840"/> </picture> </p> <h2 id="s-q-l-or-sequel">"S.Q.L" or "SEQUEL"?</h2> <p>There are many internet battles about how SQL should be pronounced. Some people are for "sequel," some are for "S.Q.L.," and still others make their own pronunciations.</p> <p>The standard says that 'Ess-cue-ell' is the appropriate way of speaking SQL. However, many English-speaking database professionals still use the nonstandard pronunciation "sequel."</p> <p>Looking to the authorities: Prof. Jennifer Widom, co-author of four popular <a href="https://learnsql.com/blog/database-books/">database books</a>, pronounced <a href="https://learnsql.com/blog/sql-programming-language/">SQL Language</a> as "sequel" in her Stanford database course. Christopher J. Date in "A guide to the <a href="https://learnsql.com/blog/history-of-sql-standards/">SQL Standard</a>" (1987) also pronounced the term as "sequel".</p> <p><strong>Who is The Winner?</strong></p> <p>I guess nobody. "Sequel" gets the most votes, but Chamberlin says "Ess-Cue-Ell," and he gets an extra vote because he's the co-developer of SQL. Is the historical context that relevant?</p> <p>Also, note that implementations may have their own preferences.</p> <p>The official way to pronounce "MySQL" is "My Ess Que Ell" (not "my sequel"), but some do not mind if you pronounce it as "my sequel" or in some other localized way.</p> <p>Microsoft SQL Server is also very often pronounced as "sequel server": <b>Bill Gates</b> uses it on his <a href="https://www.youtube.com/watch?v=5ycx9hFGHog" target="_blank">SQL Server/Miller Lite Commercial</a>.</p> <div class="youtube-wrapper " style="--widthAR: 16; --heightAR: 9; "><iframe src="https://www.youtube.com/embed/5ycx9hFGHog" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe></div> <p>Martin Fowler, the co-author of NoSQL Distilled pronounces it "No-sequel" database. See: <a href="https://www.youtube.com/watch?v=qI_g07C_Q5I" target="_blank">Martin Fowler's talk from the GOTO Aarhus Conference 2012</a>.</p> <div class="youtube-wrapper " style="--widthAR: 16; --heightAR: 9; "><iframe src="https://www.youtube.com/embed/qI_g07C_Q5I" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe></div> <p>If you look at Oracle's official documentation on SQL, it says it's still pronounced "sequel."</p> <p>However, PostgreSQL wouldn't sound right as "postgresequel" but "post-GRES-que-ell" or simply "postgres". SQL was also usually paired with the acronym RDBMS (<a href="https://learnsql.com/blog/what-is-dbms/">relational database management system</a>). SQL/RDBMS isn't pronounced "sequel-reedbums" but rather "S-Q-L-R-D-B-M-S", as pointed out by an anonymous user in one of the many S.Q.L. vs. sequel discussions.</p> <p> <picture><source srcset="usage-of-sql-and-sequel.webp" type="image/webp"><img src="usage-of-sql-and-sequel.png" alt="" class="" loading="lazy" width="735" height="400"/> </picture> </p> <p>There is little consistency in database products. One thing that is commonly seen is that almost everyone who is talking about the language itself uses "S.Q.L." When talking about a product or a vendor dialect, "sequel" is used. For example, "PL – sequel" (PL/SQL), "Transact – sequel" (T-SQL), and "sequel server" (Microsoft SQL Server and Sybase SQL Server).</p> <p>MySQL, PostgreSQL and SQLite all have official pronunciations of S.Q.L. Microsoft and Oracle products have adopted the pronunciation "sequel" However, thinking about Oracle's acquisition of MySQL, we might start to wonder: will we soon be saying "My sequel" or will we still say MySQL?</p> <div class="rek-banner " style="" banner-url="/"></div> <p>Oracle and Microsoft are giants in the database world, so should we respect their way of saying SQL?</p> <p>Many argument: "If I was using Sequel, I'd call it "sequel." I'm using SQL, so I call it S.Q.L." People can let their imaginations run wild inventing more pronunciations: let go their imagination inventing more: squall, sqwool, sqwll, squirrel</p> <p>Finally, is it relevant and important to debate the proper way to pronounce SQL? Some users believe that it is.</p> <h2 id="community-debate-on-sql-pronunciation">Community Debate on SQL Pronunciation</h2> <p>How people say "SQL" has led to many lively talks on popular online forums like Reddit and StackOverflow, where tech lovers and experts come together to exchange ideas.</p> <p>On Reddit, you'll find lots of discussions in tech and programming groups where people argue strongly for saying it as “S.Q.L” or “sequel”. These discussions often get into why people prefer one way over the other, mentioning things like where they're from or their background in tech. Here are some the most popular threads:<br /> </p> <ul> <li><a href="https://www.reddit.com/r/NoStupidQuestions/comments/41wdnr/is_sql_pronounced_s_q_l_or_sequel/">Is SQL pronounced "S. Q. L." or "Sequel"?</a></li> <li><a href="https://www.reddit.com/r/compsci/comments/e2ip8x/how_do_you_pronounce_sql/">How do you pronounce SQL?</a></li> <li><a href="https://www.reddit.com/r/SQL/comments/tl3jrt/didnt_make_it_to_the_second_interview_because_i/">Didn't make it to the second interview because I kept referring to SQL as the letters, not by the name "Sequel". Is it really taboo to refer to SQL as "Es Cue El"? I only repeat the letters 'S', 'Q', 'L', but I had no idea its that important.</a></li> </ul> <p>On StackOverflow, you can <a href="https://stackoverflow.com/questions/18523040/what-is-the-difference-between-sequel-and-sql">join this discussion</a>. Spoiler alert: the verdict here is not conclusive either.</p> <p>Be aware that there is another big debate about how to pronounce "data." People are split between "day-ta" and "dah-ta." This isn't just about preference; it shows how accents, media, and culture shape our speech. Each side has its arguments based on personal experiences and contexts. If you have time, you can dive into this rabbit hole and pick a side yourself.</p> <p>So, do you have your own preference for saying "SQL?"</p> <p>Don't forget to check our SQL courses offer at <a href="https://learnsql.com/">LearnSQL.com</a>.
