MySQL:当价格< 50时，总和(价格+14)

Question

我正在构建一个查询，如果商品价格低于 50 美元，则会自动将运费添加到商品价格中；如果原始价格超过 50 美元，则会自动添加更高的运费。我已经做了一些实验与 CASE、IF 和 SUM，但我不确定哪一个是我需要的。

初始:

Stock_Number    Line Part_Number Q  T   Price
AAB_1074901519, AAB, 1074901519, 1, AM, 120.67
AAB_1074908119, AAB, 1074908119, 1, AM, 108.29
AAB_1264907619, AAB, 1264907619, 1, AM, 364.49
AAB_1294908319, AAB, 1294908319, 1, AM, 368.97
AAB_1378254,    AAB, 1378254,    1, AM, 36.18

期望:

AAB_1074901519, AAB, 1074901519, 1, AM, 144.67   //Because price > 50, +22
AAB_1074908119, AAB, 1074908119, 1, AM, 130.29   //Because price > 50, +22
AAB_1264907619, AAB, 1264907619, 1, AM, 386.49   //Because price > 50, +22
AAB_1294908319, AAB, 1294908319, 1, AM, 390.97   //Because price > 50, +22
AAB_1378254,    AAB, 1378254,    1, AM, 50.18   //Because price < 50, +14

阿尼尔解决了我的问题。感谢大家的努力!

You can use case statement. Here is the query. Substitute table names and column names.

select case when price < 50 then price + shipping cost else price end from your table;

Answer 1

您可以使用 case 语句。这是查询。替换表名和列名。

select case when price < 50 then price + shipping cost else price end from your table;
