使用维表进行主表中不存在的数据组合

问题描述 投票：0回答：1

我有一个生成报告的存储过程。实际的报告有点复杂，因此我将尝试通过表格示例来尽可能简单地说明自己：

我的主表具有以下数据：

table1

╔════╦═══════╦═════════╦═══════╗
║ id ║ price ║ Item_id ║ name  ║
╠════╬═══════╬═════════╬═══════╣
║ 1  ║ 3     ║ 11      ║ item1 ║
╠════╬═══════╬═════════╬═══════╣
║ 2  ║ 5     ║ 22      ║ item2 ║
╠════╬═══════╬═════════╬═══════╣
║ 3  ║ 6     ║ 33      ║ item3 ║
╠════╬═══════╬═════════╬═══════╣
║ 4  ║ 7     ║ 44      ║ item4 ║
╠════╬═══════╬═════════╬═══════╣
║ 5  ║ 8     ║ 55      ║ item5 ║
╚════╩═══════╩═════════╩═══════╝

而且我有代码：

select id, 
         CASE 
             when price <= 2    THEN '01-02'
             when price <= 3    THEN '03-04'
             when price <= 4    THEN '05-05'
             when price <= 5    THEN '05-06'
             ...ETC
         END as price,
Item_id,
name
from table1

现在，根据我的数据，在这种情况下，没有价格“ when price <= 2 THEN '01-02'”，因此该选项不会出现在最终报告中，但是我希望它显示为0。

我知道为此，我需要对带有“维”表的左联接进行使用才能使用模板，但我不知道该如何实现。

我不确定它是否是一个包含我要显示的内容的所有组合的表，例如"'01-02'"，然后与之联接，但这似乎不起作用。

这是SP中的代码：
