问题:
Both these joins will give me the same results: 这两个连接将给我相同的结果:
SELECT * FROM table JOIN otherTable ON table.ID = otherTable.FK
vs 与
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他方面是否有区别?
Does it differ between different SQL implementations? 不同的SQL实现之间是否有所不同?
