Definition: From is used with Select in MySQL to choose what table to query from. You can choose to include more than one table by using a comma [,].
This shows all data on the table called Table_name
SELECT * FROM Table_name;
If you store a person's address in one table (we have called it address) and you store the names of the cities associated with each zip code in another table (we have called it city) then the above query will return the name of a person, and the name of their city. When using 2 tables, refer to the data fields as table.field.
SELECT address.person, city.name FROM city, address WHERE (city.zipcode = address.zipcode)
