Sql 统计过去5分钟内特定日期、特定商店、特定终端在过去5分钟内的交易数量

我正在尝试计算当前事务在过去5分钟内发生的事务数

CALL_DAY    TRANS_TIME  STORE_NUM   TERMINAL    CUSTOMER_NUMBER
20130201    10:46:04    1111               1                  1
20130202    17:09:19    1111               2                  2
20130202    17:10:30    2222               3                  3
20130202    17:11:35    2222               3                  3
20130202    17:13:26    2222               3                  4

以上是发生的所有单独交易。我试图找出在过去5分钟内，在特定的一天、特定的门店号、特定的终端发生了多少笔交易，并为每一行创建一列，说明每笔交易的编号

CALL_DAY    TRANS_TIME  STORE_NUM   TERMINAL    CUSTOMER_NUMBER
20130201    10:46:04    1111               1                  1
20130202    17:09:19    1111               2                  2
20130202    17:10:30    2222               3                  3
20130202    17:11:35    2222               3                  3
20130202    17:13:26    2222               3                  4

到目前为止，我已经将日期和时间转换为如下所示的datetime函数。然后，我尝试使用DATEADD函数，但这并没有实现我试图找到的结果。有人知道如何做到这一点吗

/* Converting to DATETIME */
Data NEW_FILE ; 
SET DATA.MY_FILE; 
new_call_day = input(compress(call_day),yymmdd8.);  
format new_call_day date9.;                         
new_time = input(compress(trans_time), HHMMSS8.);   
format new_time HHMM5.;                            
dtetime  = dhms(compress(new_call_day),0,0,compress(new_time)); 
format dtetime datetime22.                                
RUN;

在此之后，我尝试了DATEADD，但它没有为我想要的每一个创建一列。我被卡住了。。。也许我走错路了？

TL；博士 使用SQL子查询。它们速度很快，特别是如果您可以将执行传递给DBMS并且易于维护的话

PROC-SQL-NOPRINT； 创建表格Work.TransWithCount AS 选择STORE_NUM 航空站 ，TRANS_DT , 选择计数* 从工作中。转换为T 其中T.STORE\u NUM=P.STORE\u NUM T终端=P终端 和T.TRANS_DT>=P.START_DT T.TRANS_DT=P.START_DT

我不知道你说的“试过约会”是什么意思。这不是SAS函数…您正在查看多少数据？这是数百万行吗？数十亿？这将有助于查看一些示例输出数据…您希望如何处理上述示例输入数据DateAdd是一个SQL SERVER函数，SAS中的等效函数是INTCK。我正在处理大约10万行。抱歉，我不准确，我尝试使用DATEADD bc SAS，也可以使用SQL。
