JOIN和INNER JOIN之間的區別 - Difference between JOIN and INNER JOIN

問題:

Both these joins will give me the same results: 這兩個鏈接將給我相同的結果: 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? 語句之間的性能或其餘方面是否有區別? .net

Does it differ between different SQL implementations? 不一樣的SQL實現之間是否有所不一樣? code
