Difference between select and inner join?
The select command is the mechanism for retrieving records from a SQL database. In it's simplest form, this would be FROM a single table, for example - select * from CustomerTable.When data is needed from multiple tables, each pair of tables has to be linked together using a JOIN. The easiest type of join is an INNER JOIN, which expects the data to be in both tables. For example, if a customer record had a 'STATE' code which looked up against the US States and we want our SELECT to return the State name as well as the customer code, it would look something like this;SELECT CustomerCode, CustomerName, StateName FROM Customer INNER JOIN State on (State.ID = Customer.StateCode)
