Can you sort more than one column at a time using Excel?
No, you can sort multiple columns or rows if you hightlight a range, but all columns or rows will need to be sorted with the same criteria (e.g. lowest to highest). You can sort an entire row by clicking on the row number at the left of the screen, then sort, as desired. You also can do the same for columns by clicking on the column letter at the top of the screen.

What is the table's primary key?
Primary key is the unique attribute among all attributes of an object, which alone is sufficient to represent a sigle entity. for example a table has columns student id, stdent name, father name, class, department etc. so here "student id" is primary key bcoz it cann't be same for two students, where other attributes like name and class can be same for more than one student. hence primary key is the attribute which represent a unique entity and is sufficient to search the tuple (row) of table having that primary key value.

What is a compound primary key?
There are atomic and compound primary keys used to quikly find the rows of a table you are looking for. This is more than just an idex - it helps find the one row you want like finding a needle in a haystack. Atomic keys use only one column and can not be broken down - hence atomic. Compound primary keys are made up of two or more columns from the same table. For performance reassons try to use the first columns and preferably have them close together. A table can have more than one unique index but only 1 (one, uno) primary key. You can not create a primary key that uses a column from another table. So far no one has implimented functional primary keys where the primary key is the result of a function. There are encrypted primary keys. Why use a compound primary key? So you can take the key apart quickly or validate its pieces first. If you use telephone numner (555) 555-1234 as a primary key would it not be nice to know 1) the first part is a valid 3 digits area code and not 011 a country code? 2) that the next 3 digits are a valid exchange 3) that the last part is valid By keeping the parts separate you can alos do fun quiries on "How many phones are in my exchange of 555 ? How many are in my area code? How often does my exchange or phone number apprear in other states? This would be much harder to do if the primary key was stored as a single number 5555551234.
