Selecting columns and rows

Often, you are interested in only columns in a table. For example, to make up birthday cards for employees you might want to see the Surname, DepartmentID and BirthDate columns.

In this section, you will select each employee's birth date, last name, and department ID. Type the following:

SELECT Surname, DepartmentID, BirthDate
FROM Employees

The three columns appear in the order in which you typed them in the SELECT command. To rearrange the columns, simply change the order of the column names in the command. For example, to put the BirthDate column on the left, use the following command:

SELECT BirthDate, Surname, DepartmentID
FROM Employees

You can order rows and look at only certain columns at the same time as follows:

SELECT BirthDate, Surname, DepartmentID
FROM Employees
ORDER BY Surname

The asterisk in

SELECT * FROM Employees

is a short form for all columns in the table.
