Sql 两个存储过程结果集的合并应该在数据库端还是在API端进行？

下面是API，我需要创建一个新的存储过程来返回它。“MemberCard”前面的上部有一个可以输出它的存储过程，“MemberCard”的子细节也有自己的存储过程。如何以下面相同的格式组合这两个存储过程的结果集？还是Java API应该合并2个sp的结果集

样本响应：

以下是将resultset合并到单个SP中的操作

假设您的表名是Member（主表）和MemberCard（子表），并且从Member到MemberCard具有一对多关系

左键连接主（成员）和子（成员卡）表，该表将生成单个结果集。这将为每个membercard生成一行，这意味着如果一个成员有多个membercard，您将获得重复的成员详细信息；如果成员没有membercard，则membercard的值为空

在JavaAPI中，您可以对成员执行内存分组，并生成所需的对象结构

存储过程的示例查询

SELECT 
 M.Action,
 M.CardNumber,
 M.MemberMobilePhone,
 M.SMSValidation,
 M.MemberToken
 --Other fields from Member table
 MC.OctopusID,
 MC.BrandPicGFile,
 MC.CardTypeName,
 MC.CardExpiryDate
 -- Other fields from MemberCard table

FROM Member M
LEFT OUTER JOIN MemberCard MC ON MC.MemberId = M.MemberId
--Your filter conditions etc

你没有提到合并到单SP中的目的，但是如果你想减少数据库调用，那么你可以考虑上面的方法。此外，如果您的结果集很大，请在SQL查询中应用分页

谢谢，你的回答足够了。
