有两个表
在资格表中，如果员工的类别类别为MED_COPAY，MED_COINS，RX_DED，RX_COPAY，则Dependent也应符合这些类别的条件。
所以基本上我需要以下类型的输出，其中硬币，copay＆amp;如果员工没有categoryID = MED_DED，则可扣除列应位于单独的行中，因此不应将该记录包含在employee＆amp;的输出中。依赖记录。
索赔表中的服务类型列如下
H =医疗（MED_COPAY，MED_DED＆amp; MED_COINS）
P = Pharma（RX_COPAY，RX_DED＆amp; RX_COINS）
这是索赔表

答案 0 :(得分：1)
正如我之前提到的，您有一个非常严重的数据库设计问题，使查询变得困难。无论如何它是：
SELECT Patient_First_Name,
Patient_Last_Name,
CASE RIGHT(CategoryId,5)
WHEN 'COINS' THEN Coins
WHEN 'COPAY' THEN Copay
ELSE Deductible END StrangeValue,
CASE WHEN categoryId IS NULL THEN 'MED_DED'
ELSE categoryId END categoryId
FROM claim c
LEFT JOIN Eligibility e
ON e.Dependent_First_Name IS NULL
AND e.Dependent_Last_Name IS NULL
AND categoryid IS NOT NULL
AND (Service_Type = 'H' AND CategoryId IN ('MED_COPAY', 'MED_DED', 'MED_COINS'))
ORDER BY patient_first_name DESC, patient_last_name, categoryid, coins DESC
我不确定自己是否了解自己的需求，但这会回复你所说的预期。
编辑： 遗憾
SELECT Patient_First_Name,
Patient_Last_Name,
CASE RIGHT(CategoryId,5)
WHEN 'COINS' THEN Coins
WHEN 'COPAY' THEN Copay
ELSE Deductible END claimValue,
CASE WHEN categoryId IS NULL THEN 'MED_DED'
ELSE categoryId END categoryId
FROM claim c
LEFT JOIN Eligibility e
ON e.Dependent_First_Name IS NULL
AND CategoryId IN ('MED_COPAY', 'MED_DED', 'MED_COINS')
