Dapper中SELECT查出来之后根据结果返回值

var result = await connection. QueryAsync< DeliveryOrderException>(

@"SELECT

D.DeliveryOrder_ID AS DeliveryOrderId,

D.SAP_DeliveryOrder_ID AS SAP_DeliveryOrderId,

D.SAP_RequiredDate AS DeliveryDateTime,

CASE

WHEN D.PhaseStatusCode = 0 THEN 'PICKPACK'

WHEN D.PhaseStatusCode = 1 THEN 'STAGE'

WHEN D.PhaseStatusCode = 2 THEN 'LOAD'

WHEN D.PhaseStatusCode = 3 THEN 'INTRANSIT'

WHEN D.PhaseStatusCode = 4 THEN 'DELIVERED'

END AS Phase, R.DisplayCode AS Reason,

R.DisplayCode AS Reason

LEFT JOIN Customers AS C ON D.Customer_ID = C.Customer_ID

LEFT JOIN ReasonType AS R ON D.Reason = R.ReasonCode

                    WHERE D.ProgressCode = @progressCode

                    ORDER BY D.DeliveryOrder_ID DESC

                    OFFSET ( @pageNo - 1 ) * @pageSize ROWS

                    FETCH NEXT @pageSize ROWS ONLY", new { pageNo, pageSize, progressCode = DeliveryOrderProgressCode. Exception}
