Question

我的目标是为我们的库存系统创建一份报告，以显示我们是 IN 库存还是 OUT 的产品库存A B＆amp; C.我们的股票分为两列，分别为physical_qty和allocated_qty

使用此查询，我可以从physical_qty中减去allocated_qty并将其显示为stock

SELECT     
   warehouse, product, description, physical_qty - allocated_qty AS stock
FROM         
   scheme.stockm
WHERE     
   (warehouse = '01') AND (product IN ('A', 'B', 'C'))

这给了我们可以出售的股票数量的数值。

我如何评估库存是否为＆lt; 1显示 OUT ，否则显示 IN ？

Answer 1

像这样：

SELECT     warehouse, product, description, 
physical_qty - allocated_qty AS stock,
CASE WHEN (physical_qty - allocated_qty) < 1 THEN 'OUT'
ELSE 'IN' END AS Stock_Status
FROM         scheme.stockm
WHERE     (warehouse = '01') AND (product IN ('A', 'B', 'C'))

Answer 2

尝试

CASE WHEN physical_qty - allocated_qt < 1 THEN 'OUT' ELSE 'IN' END

使用“AS”时的SQL CASE
