我正在做一个有产品反馈的项目，我似乎已经走到了尽头，我需要通过从4个不同的表中收集数据并在产品名称下合并/分组来生成产品活动报告。我的表格如下：
+------------+
| ProductUSP |
+------------+
| intID |
| intProdID |
| chrProdUSP |
| chrRemarks |
+------------+
+------------------+
| ProductDetails |
+------------------+
| intID | --this is the same as the intProdID in the other tables
| chrProdName |
+------------------+
+---------------------+
| ProductActivity |
+---------------------+
| intID |
| intProdID |
| chrSalesActivity |
| chrPurchaseActivity |
| chrNewLauches |
+---------------------+
+-------------------+
| ProductVariety |
+-------------------+
| intID |
| intProdID |
| chrHighEndVariety |
| chrMidVariety |
| chrLowVariety |
+-------------------+
+----------------+
| ProductPricing |
+----------------+
| intID |
| intProdID |
| chrHighPricing |
| chrMidPricing |
| chrLowPricing |
+----------------+
问题是第一个表有一个产品ID的多个记录，所有其他表都有一个产品ID的记录，因此我在select语句中不断获取重复值。
我得到的结果如下：
ProdUSP1 | SalesActivity | HighVariety | HighPrice
ProdUSP1 | PurchaseActivity | MidVariety | MidPrice
ProdUSP1 | NewLaunches | LowVariety | LowPrice
ProdUSP2 | SalesActivity | HighVariety | HighPrice
ProdUSP2 | PurchaseActivity | MidVariety | MidPrice
ProdUSP2 | NewLaunches | LowVariety | LowPrice
ProdUSP3 | SalesActivity | HighVariety | HighPrice
ProdUSP3 | PurchaseActivity | MidVariety | MidPrice
ProdUSP3 | NewLaunches | LowVariety | LowPrice
我想按如下方式打印结果，只使用一个查询。
ProdUSP1 | SalesActivity | HighVariety | HighPrice
ProdUSP2 | PurchaseActivity | MidVariety | MidPrice
ProdUSP3 | NewLaunches | LowVariety | LowPrice
有任何变通方法吗？可能吗？ 我希望我已经清楚地解释了......
