使用mfc 的CRecordset：：Open方法，执行一个长955个字节的sql语句出错，memcpy.asm的时候出错。是否对sql语句长度有限制还是怎地？sql server数据库。附：select TOP 1000 SerialNo,SMContent,SendTarget, LinkID,PAD2 AS ServiceInstance from SM_Send_SM_List where RCompleteHourBegin<=880 and RCompleteHourEnd>=880 and (RCompleteTimeBegin is null or (datediff(d,RCompleteTimeBegin,getdate()))>=0) and (RCompleteTimeEnd is null or (datediff(d,getdate(),RCompleteTimeEnd))>=0) and ( ( LEN(SendTarget)=14 and SendTarget not like '+8613%') or ( LEN(SendTarget)=11 and SendTarget NOT like '13%') or (LEN(SendTarget)<>14) and (LEN(SendTarget)<>11)) AND PRIORITY=(SELECT MIN(PRIORITY) FROM SM_Send_SM_List where RCompleteHourBegin<=880 and RCompleteHourEnd>=880 and (RCompleteTimeBegin is null or (datediff(d,RCompleteTimeBegin,getdate()))>=0) and (RCompleteTimeEnd is null or (datediff(d,getdate(),RCompleteTimeEnd))>=0) and ( ( LEN(SendTarget)=14 and SendTarget not like '+8613%') or ( LEN(SendTarget)=11 and SendTarget NOT like '13%') or (LEN(SendTarget)<>14) and (LEN(SendTarget)<>11)))
