SQL is also known as structured query language. I learnt it throughout my university years. Developing solutions for some problems can be very hard. But by using the basic formulas and techniques the subject can become relatively easy. In my opinion it is the best computer suhject i have completed throughout all my school and university years.

Here is what a simple solution looks like.

Select Car
From road
where car='barina'

A code with a moderate degree of difficulty looks like this.

Select book.book_name,code.code_name,car.car_name
From book, car, code, facility where book.book_name = code.code_name and
car.car_name = facility.facility_name and
facility. facility_number=code.code_number and
car='barina'

I found a nice SQL oracle tutorial video courtesy of "studentpet" from youtube. This should help with errors being created when converting your SQL codes to oracle, or other computer programs:



Advanced SQL queries are often only used by graduates. They often involve inner and continual sub queries. A lot of definitions for SQL can get rather confusing, so learning at your own pace is key to going well in the subject. Also downloading SQL software helps, as it allows you to test out some queries pointing out where it is wrong, or where the query needs to be edited. Some one on one consultations also work well. Make sure you only do computer subjects if its your strong point and not because you want to be with your friends who are in the class.
