问题描述
在查询选择中,我想显示字段是否满足条件的结果.
In a query selection I would like to display the result whether a field satisfies a condition.
假设我有一个名为 stock 的表.这张表有一列告诉我库存中每件商品的数量.
Imagine that I have a table called stock. This table has a column that tells me the number of each item in the stock.
我想做的是这样的:
SELECT stock.name, IF (stock.quantity <20, "Buy urgent", "There is enough") FROM stock
SQL Server 中是否有任何函数可以做到这一点?
Is there any function in SQL Server to do that?
推荐答案
尝试案例
SELECT stock.name, CASE WHEN stock.quantity <20 THEN 'Buy urgent' ELSE 'There is enough' END FROM stock
