    Based on the given structure, I know of two statements that will have the ability to insert a row into the table. The first one is letter A. The other statement that will have the ability to insert a row into the table is letter D. Inserting a row into the table can be important especially if you would like to keep your list of employees in alphabetical order. You want to make sure that if ever you need to find data about the employees, you simply need to input the surname and find the employee that you are looking for. There may also be different categorizations that you may use so you can find the employees you need easily. For example, you may come up with a category wherein the people from one department will be lumped together depending on the specification that you will choose. The year employed is also another category you may consider doing.

  • How do you create a salary table?
    How do you create a salary table?
    Creating a salary scale command is not something that people know initially especially if they have never received any training from it but those who are aware of how to do this command would simply need to set it at D.4 and f.7. Once you have created the command, that is the time when you can start making the salary spreadsheet. This will allow you to keep track of the different people’s salaries and how much they would get. You can always start by creating your own worksheet. Make sure that you will name it appropriately so you will know the filename to look for whenever you need to access it. You can create specific columns depending on the details that you will input in the salary sheets.

  • Which data manipulation operation do you perform when you add new information to an existing table?
    Which data manipulation operation do you perform when you add new information to an existing table?
    You update the table when you add new information. There are various ways to do this, but it all depends on the system you’re using. I am not incredibly familiar with Oracle. However, I am familiar with making a table in Word, and it’s pretty easy to update those tables. The skill isn’t incredibly transferrable when it comes to doing cross-program training. That said, there are plenty of training videos out there for those who want to learn how to do this on Oracle or in other programs that use tables to keep track of information. Most of these videos are up on YouTube and done by people who mean well, but the companies typically have FAQ or tutorial pages that will offer in-depth help if asked.
