IT professionals and students from all over the world have many options for SQL training nowadays. They can learn SQL by going to instructor-led SQL course, they can by a SQL book, they can take an online SQL training course, or they can use one of the many SQL training resources online. The first difference between the above SQL training options is the price tag. Instructor led courses usually last 2 to 5 days and can cost up to several thousand dollars. Online SQL training courses are usually less expensive, but they cost in hundreds of dollars most of the time. Another SQL training option is buying SQL training DVDs. Again the price may vary from $50 to $1,000. Buying a SQL book is the most inexpensive way for SQL preparation (usually cost between $30 and $100). The last option is to use free online resources like SQL-Tutorial.net or SQL Training.
Each of the SQL training alternatives has its pros and cons. For example the instructor led courses have the advantage of real time communication with the instructor and hands-on SQL training. On the other hand they are very expensive and not everybody will be willing to invest thousands of dollars for SQL education. If you can get your company to pay for such SQL course, donít miss the opportunity.
You can buy SQL training DVDs, but the content wonít be interactive most of the time, which is a drawback. The advantage of the SQL DVD is that is less expensive.
If you buy a SQL training book, make sure that the book has good reviews; otherwise you will be wasting your money.
Finally Ė Practice, practice and practice again the SQL skills you have learned, no matter which SQL training avenue do you choose.
