我需要幫助創建基於此查詢在SSRS的表達在SSRS A = CountDistinct:如何創建基於查詢
SELECT COUNT(DISTINCT person_id) FROM person_table
WHERE (employed = 'Y' or title = 1)
or (start_date = '' or start_date = '00000000'
or start_date > CONVERT (VARCHAR,GETDATE(),112))
所有,我到目前爲止,這是
=CountDistinct(IIf(Fields!no_unresolved_allergies_ind.Value = "Y",Fields!MRN.Value,Nothing))
你可以發佈你的模式嗎? – bpachev
