在上面的示例中,根据"UnitsInStock"的值,使用"CASE"语句将库存状态设置为"In Stock"、"Out of Stock"或"Unknown"。 请注意,SQL Server 2012及更高版本还引入了"IIF"函数,它是一种条件表达式,可以更简洁地实现类似于"DECODE"的功能。以下是使用"IIF"函数的示例: ```sql SELECT ProductName, UnitsInStock, ...

tips:str通过encode()方法可以编码为指定的bytes。反过来,当从网络或磁盘上读取了字节流,那么读到的数据就是bytes。要把bytes变为str,就需要用decode()方法。反之,则使用encode()方法即可! T2、众多网友好评的建议 谢谢improve100网友提供的建议! 代码语言:javascript ...
