JOIN和INNER JOIN之间的区别 - Difference between JOIN and INNER JOIN

问题:

Both these joins will give me the same results: 这两个链接将给我相同的结果: 性能

SELECT * FROM table JOIN otherTable ON table.ID = otherTable.FK

vs spa

SELECT * FROM table INNER JOIN otherTable ON table.ID = otherTable.FK

Is there any difference between the statements in performance or otherwise? 语句之间的性能或其余方面是否有区别? .net

Does it differ between different SQL implementations? 不一样的SQL实现之间是否有所不一样? code
