-- [求助]sql 查询 null 和 “” 的处理
应该查出两条数据的，但只查出一条数据，该怎么改查询语句？自己搞定了
Sel ect * From (Sel ect top 50 Row_Number() Over(Order by [用车日期]) As [NO.],[_Identify],CONVERT(varchar(10),[用车日期],120) as [用车日期],[车辆牌照],[司机],[指挥],[车型],[计费车型],[用车单位],[二级单位或地点],[作业内容],[到场时间],[预计用时],[路单登记],[备注] From YW_排工明细 where DateDiff(dd,[用车日期],getdate()) <= 40 and ([司机] like \'%李%\' or [指挥] like \'%李%\') and [路单登记] not like \'%李%\' or [路单登记] is null ORDER BY [NO.]) As a Where [NO.] >= 1 And [NO.] <= 15

应该这样吧
... where DateDiff(dd,[用车日期],getdate()) <= 40 and ([司机] like \'%李%\' or [指挥] like \'%李%\') and ([路单登记] not like \'%李%\' or [路单登记] is null ) ORDER BY [NO.]) As a Where [NO.] >= 1 And [NO.] <= 15
