can some one tell me a little about LEFT JOIN ?

[Joe Pimms]

what im trying to do is be able to view all info in the database table called serial and the other items hold different things...

1.. the serialid
2.. the serialname this is the part that will hold the name of the text or post name
3.. the userid this is the part that holds the user name that makes the posts
4.. the dateline this is the date that the post was made
5.. the serialnumber this is the full post that was made all the text in the post and all

what im wanting to do is also make a add forum and a submit with it as well for a new forum and also have an other php script that will display the post contents as well but the only problem im having is the database not to sure on how to make all the right commands and all so please help me with any ideas or any thing else

thanks so much :smoke:
