This doesn't work:

这不起作用:

UPDATE customers SET firstname="John" AND lastname="Smith" WHERE id=1;

Separate values with commas. ANDis an logical operator, its place is in WHEREand ONclauses.

用逗号分隔值。AND是一个逻辑运算符,它的位置在WHEREandON子句中。

UPDATE customers SET firstname="John", lastname="Smith" WHERE id=1;
