我拥有的SQL是这样的：

SELECT *
FROM (SELECT O_ASSESSMENTS.ASM_SUBJECT_ID as "P Number", 
             O_ASSESSMENTS.ASM_ID as "Assessment ID", 
             O_ASSESSMENTS.ASM_START_DATE as "Assessment Start",  
             O_ASSESSMENTS.ASM_END_DATE as "Assessment End", 
             O_SERVICE_EVENTS.SEV_ID as "Event ID", 
             O_SERVICE_EVENTS.SEV_ACTUAL_DATE as "Event Start", 
             O_SERVICE_EVENTS.SEV_OUTCOME_DATE as "Event End",
             ROUND(O_ASSESSMENTS.ASM_START_DATE -O_SERVICE_EVENTS.SEV_ACTUAL_DATE,0) as "Likely",
             row_number() over(PARTITION BY  O_ASSESSMENTS.ASM_ID                                    
                               ORDER BY abs(O_ASSESSMENTS.ASM_START_DATE -  O_SERVICE_EVENTS.SEV_ACTUAL_DATE))as "Row Number"            
      FROM O_ASSESSMENTS 
      JOIN O_SERVICE_EVENTS
        ON O_ASSESSMENTS.ASM_SUBJECT_ID = O_SERVICE_EVENTS.SEV_SUBJECT_ID
      Where O_SERVICE_EVENTS.SEV_CODE IN ('ICS_E3','CPINVEST') AND 
            O_ASSESSMENTS.ASM_QSA_ID  IN ('AA1329','AA521') )
WHERE "Row Number" = 1

基本上，我们有两个表-
o_assessments和o_service_events，并且此SQL将最近的服务事件返回到评估中。现在，我想在查询中包含一些更复杂的信息，以使其对最终用户更有帮助-
即团队名称和工作人员名称。

不幸的是，团队和工作人员又在另一个表中（o_职责），并且通过asm_id与res_rec_id链接到o_assessments。

问题是，我真的不确定如何在上述sql中调用此表-因此，任何建议都将不胜感激！

我还想知道是否有可能调整现有查询以仅在“可能”字段的差为0（因为更大的值可能与该特定评估无关）时仅返回对应的事件。我知道我可以将其添加到where，但是如果我添加该行

and "Likely" = 0

它仅返回带有事件的评估，而不会突出显示任何问题（即没有相应事件的评估）。

我一直在使用SQL进行学习，但是目前有很多事情似乎真的超出了我的范围，因此，任何建议都将不胜感激！我不确定是要修改原始查询还是开始新查询，所以我希望我没有无意间违反任何规则。

好的，按照Mark的解决方案，这就是我的工作。
