Question

请帮我搞定。

输入

Part_Number,Part_Type,Description_1,Value1, Description_2,Value2,Description_3 Value3

EDG38305,Gauge, Compatibility,CTS, Location,Dashboard,Head Light,DISC

我需要这样的输出。

输出

Part_Number,Part_Type,Description_1,Value1, Description_2,Value2,Description_3 Value3

EDG38305,Gauge, '','', '','',Head Light,DISC

仅包含DISC的值列，其中包含相应描述，如果值3为DISC那么输出显示说明3和值3以及剩余电量剩余空白

谢谢大家

您可以使用以下查询

SELECT Part_Number,Part_Type,
      CASE WHEN  Value1 = 'DISC' THEN Description_1 ELSE '' END AS Description_1,
      CASE WHEN  Value1 = 'DISC' THEN Value1 ELSE '' END AS Value1,
      CASE WHEN  Value2 = 'DISC' THEN Description_2 ELSE '' END AS Description_2,
      CASE WHEN  Value2 = 'DISC' THEN Value2 ELSE '' END AS Value2,
      CASE WHEN  Value3 = 'DISC' THEN Description_3 ELSE '' END AS Description_3,
      CASE WHEN  Value3 = 'DISC' THEN Value3 ELSE '' END AS Value3

您必须根据要检查的所需静态值数来更改IN子句

在多列中搜索值
