 我最近了解到在Oracle中我们可以做类似的事情 
 
select t1.a, t2.b 
from table1 t1, table2 t2
where t1.x = t2.x
 
 这相当于 
 
select t1.a, t2.b
from table1 t1
join table2 t2 on (t1.x=t2.x)
 
 是否有任何性能差异或是否有任何其他参数我们应该使用一种风格而不是另一种风格？

 Will ANSI JOIN vs. non-ANSI JOIN queries perform differently?  7 answers  
 
 
 
 
I have recently learned that in Oracle we can do something like 
 
select t1.a, t2.b 
from table1 t1, table2 t2
where t1.x = t2.x
 
which is equivalent to 
 
select t1.a, t2.b
from table1 t1
join table2 t2 on (t1.x=t2.x)
 
Is there any performance difference or are there any other arguments that we should use one style instead of the other?
