What does primary key mean in database form?
In a Database, more specifically a relational model, columns of one table that relate to columns of another table are called "key columns". There are two types of "key" columns. Foreign key and Primary Key. The Primary key of a table is usually a column within a table that contains unique data which cannot be duplicated. Think of it as a "unique identifier" column. You can actually create an array of key columns in a table to represent a unique series of values as well. (so PKey 1,2,3 are unique and no group of PKey's 1,2,3 will be the same, even though sometimes any one of those columns may contain a single value that has been duplicated, the consolidated value of all 3 will never be replicated). The Primary key of table A is linked to the Primary key of Table B for instance. Table B's Primary Key in this relationship is then called a "Foreign Key", meaning "The Primary Key of the OTHER table". That's a pretty basic understanding of how they work. There is a little bit more involved but this is the gist of it.
How do you program WV caddy key fob?
This doesn't work if you lost all the "primary" keys - the ones that have the remote unlock functions on them. And it doesn't work if your primary key isn't working. If all you have is a valet key, you need to go back to the dealer, who uses a computer to program them.If you have a good primary key and a new fob that has the key blade cut, this is what you do:1. Put the key you want to program in the ignition and turn the car to "on." Don't try to crank the engine.2. Get out of the car and close the door. Take the working primary key and put it in the doorlock. Manually lock the car by turning the key. Remove the key from the lock.3. Push the "unlock" button on the key fob. Wait at least one second and push it again.4. Get in the car and turn the key to the "off" position. Remove the key.The key is now programmed to your car.

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.
