SQL JOIN - WHERE 子句與 ON 子句 - SQL JOIN - WHERE clause vs. ON clause

問題：

After reading it, this is not a duplicate of Explicit vs Implicit SQL Joins .閱讀後，這不是Explicit vs Implicit SQL Joins的重複。 The answer may be related (or even the same) but the question is different.答案可能相關（甚至相同），但問題不同。

What is the difference and what should go in each?有什麼區別，每個應該包含什麼？

If I understand the theory correctly, the query optimizer should be able to use both interchangeably.如果我正確理解了理論，查詢優化器應該能夠互換使用兩者。
