大神们，帮我找下问题呢。写SQL的时候，数据能查出来，当时做报表的时候却报错。

select a.ACTUAL "粘度",a.test_date_time "时间" from "WIP"."PARAMETRIC_MEASURE" as a,"WIP"."PARAMETRIC" as b

where a.measure_name = 'MXCPS'

and a.MEASURE_GROUP =  'NDZDSC'

and right(b.RESOURCE_BO ,8)= 'MIXIV031'

and a.TRANSACTION_ID=b.TRANSACTION_ID

and a.test_date_time between '${DATEDELTA(TODAY(),-30)}' AND '${TODAY()}'
