+ sign before column name - what does it mean?

875641Jul 14 2011 — edited Jul 14 2011
Hi all,

I found a query in the software package I work on today that I don't quite understand. Below is that basic form of the query:

SELECT * FROM table1 t1, table2 t2 WHERE + t1.id = t2.id;

I expected this query to fail, but it did not. What does the '+' in front of t1.id indicate?

Thanks in advance.

You can also use perfanal utility provided in java.sun.com. It is very useful in interpreting the results of hprof.
