You will only get a reward from what you can do. There are some people out there that never move further to see what they should do which is making them do things in the wrong way. Well, you should know that this is not right and you will never make success in this manner. As someone that will want to move on what you need, you will encourage yourself to see how you can equip yourself with more knowledge and this is something that can happen using http://sqlsplus.com/. This is what those that want to take control of their stand and a database professional, do.
It is going to work out fine when you can see the need to go for more than one database language. The interesting thing about these languages is that they look-alike and as someone that will want to make something good in his line of work, it will be good you see good in doing things this way. Command lines sometimes are not always the same as the language you write with before, but there is surely going to be something similar. It is no more story that it's those that know more language that will be able to handle some database work. This is just the truth and you looking away from that will never help you.The only thing you should be thinking of doing as a programmer is never to let everything be the same. You are just going to get deformed with time as some programming language will no longer be effective as time goes on.
