CROSS JOIN 和 INNER JOIN 有什么区别？IE

table 1
+ID   +NAME + LAST__NAME
+-----+-----+-----------
+1    +John + Doe
+2    +Phil + Smith
+3    +Jane + Peterson


table2

+ID+Department
+--+----------
+1 + TI
+2 + Sales
+3 + TI

Run Code Online (Sandbox Code Playgroud)

SELECT *
FROM table1
INNER JOIN table2
ON table1.id=table2.id;

SELECT *
FROM table1
CROSS JOIN table2

我想知道结果之间有什么区别
