所以我有以下代码 - 由第三方供应商编写。任何人都可以建议应该使用哪些索引来防止书签查找？您是否也需要UDF的内容？
SELECT reportTbl.ReportDBID,
case when reportTbl.ResultStatus = 'P' then 'PRELIMINARY'
when reportTbl.ResultStatus = 'I' then 'INTERIM'

LEFT OUTER JOIN cdrOth WITH (NOLOCK) ON reportTbl.ordID = cdrOth.SegCrossReferenceDBID
WHERE
patientTbl.recNumber ='111111111'
and reportTbl.ResultStatus IN ('G', 'H','I', 'J')
and reportTbl.DiagnosticServSectID IN ('E', 'F')
and reportTbl.UniversalServiceCode NOT IN ('A', 'B', 'C', 'D') -- there are roughly 750 options so using NOT IN is easier
ORDER BY ReportDBID
