Question

这是我的表batchmaster，其中包含batchname，subbatchname，records

等列

BatchName    SubBatch   records     
12032014     raw1_0     2  
12032014     raw1_0     2  
12032014     raw1_1     2  
12032014     raw1_1     2     
12302014     raw7_0    150  
12302014     raw7_0    150

我希望得到输出，例如使用不同的batchname，subbatch和不同子补丁的记录总和。

BatchName    SubBatch   records  
12032014     raw1_0     4  
12032014     raw1_1     4 
12302014     raw7_0   300

Answer 1

这对你有用

SELECT BatchName,SubBatch,SUM(records) AS SumRecords
FROM batchmaster
GROUP BY BatchName, SubBatch

Answer 2

我同意Conrad Lotz的询问。

试试这个

DECLARE @batch_master TABLE
  (
     BatchName VARCHAR(50),
     SubBatch  VARCHAR(50),
     records   INT
  )

INSERT INTO @batch_master
VALUES      ('12032014',
             'raw1_0',
             '2'),
            ('12032014',
             'raw1_0',
             '2'),
            ('12032014',
             'raw1_1',
             '2'),
            ('12032014',
             'raw1_1',
             '2'),
            ('12302014',
             'raw7_0',
             '150'),
            ('12302014',
             'raw7_0',
             '150')

SELECT *
FROM   @batch_master

SELECT batchname,
       subbatch,
       sum(records)
FROM   @batch_master
GROUP  BY batchname,
          subbatch

Answer 3

 SELECT BatchName,SubBatch,SUM(records) AS Records
    FROM urTableName
  GROUP BY BatchName, SubBatch

Answer 4

尝试以下方法：

SELECT BatchName,SubBatch,SUM(records) AS Records
FROM Table
GROUP BY BatchName, SubBatch

使用不同列进行求和
