Some people may decide not to learn SQL because of something they may have heard, or just assumed, that is completely untrue. Myths such as these can stand in the way of people moving ahead in their careers. There are number of these myths that hold people back, but I would like to discuss just four of them.
1. SQL is a programming language and I am not a programmer. Although SQL is a language, it is not a programming language in the way you are probably thinking. Most computer languages are procedural languages. To use them, a programmer creates a procedure in which a series of instructions are written in a step-by-step manner to cause a computer to perform some action. The programmer must understand what is going on at a deep level in order to generate the correct sequence of instructions.
SQL is not like that. It is not a procedural language. It is called a non-procedural language because there is no need to write a procedure. With SQL all you need to do is write a statement that tells the computer what action you want it to perform. The DBMS figures out the details of how to do that, then goes ahead and does it.
2. SQL is only for people who have a programming job. Although it is true that information technology professionals have the most to do with databases, these days practically everyone in an organization has some exposure to them and may need information contained in them in order to do their jobs. You may not work with a database every day, but occasions will arise when you will need a fact contained in a database and there is no IT professional available to obtain it for you. Anyway, you should be able to perform basic database retrieval operations for yourself. It makes you a more valuable employee.
3. You need to be some kind of brainiac to understand SQL. There is a mystique surrounding computers in general and SQL in particular that they are beyond the comprehension of ordinary people. This is particularly untrue about SQL, which consists of simple statements that are very similar to ordinary English-language sentences. If you can compose and write down a sentence, you could just as easily write an SQL statement that would perform a query.
4. Knowing SQL won’t be of any value to me. This is the biggest myth of all. Our world today is totally dependent upon computers and the data stored within them. A lot of jobs will become obsolete and disappear within the next ten years, but jobs associated with information technology will not be among them. Learning SQL could be one of the most effective things that you could do to guarantee your future employability.
