SQL Joins

Hi there,

I've been working with Editor getting to know its features, however I've got to the point where I'm trying to wrap my head around joins. This is an advanced topic I need to understand. I'm very confused as I examine the example on http://editor.datatables.net/release/DataTables/extras/Editor/examples/join.html. Seeing how the joins are instantiated in the PHP file doesn't help much when I'm trying to associate them all with an SQL select statement.

Seeing a simple SQL JOIN STATEMENT like: SELECT T1.*,T2.* FROM T1 LEFT JOIN T2 ON T1.i1 = T2.i2; is hard enough to understand where we are just dealing with two joined tables. But I can't imagine the complexity of joining four tables in one query. What does that look like?

I need to understand how a four table join is put together in an SQL statement. Would you be able to provide the SQL select statement for the above mentioned example so I can examine it and try to understand it? If you have any instructions in helping me to break it down, that would be a tremendous help.

Thanks,

Alan
