Hi, I'm using Access 2003. I'm not an SQL Guru, but rather I'm trying to learn as much as I can so that I can write good sound SQL statements. My question is regarding the parenthesis in the SELECT statement and how they are processed.
In a mathematical computation, there is a hierarchy as to which part of the equation is resolved first and which follows second and so on. -- Does that same hierarchy apply to the parenthesis; or better put, the statements within those parenthesis inside an SQL statement.
The parenthesis I'm referring to are like the ones below
LEFT JOIN Table2 ON ...)
LEFT JOIN Table3 ON ...)
LEFT JOIN Table4 ON...
Does Table1 get evaluated first or which one if any gets evaluated first and why?
