Question

我有如下表格

PARTICULAR  OPENING TRANSACTION ENDING
Expense     5456456   0         0
Expense      0        1232131   0
Expense      0        0         123123

但我希望得到如下信息

PARTICULAR  OPENING TRANSACTION ENDING
Expense     5456456  1232131    123123

是否可以使用sql查询实现此目的？

Answer 1

我想要SUM，我猜！

SELECT particular, 
       SUM(opening) AS total_opening, 
       SUM(transaction) AS total_transaction,
       SUM(ending) AS total_ending
  FROM your_table
 GROUP BY particular

Answer 2

听起来你只是想要

SELECT particular, 
       max(opening) opening, 
       max(transaction) transaction,
       max(ending) ending
  FROM your_table_name
 GROUP BY particular

Answer 3

假设交易，开始和结束仅对一行大于零，则以下内容将起作用

SELECT
   particular
   , MAX(opening) as opening
   , MAX(transaction) as transaction
   , MAX(ending) as ending
FROM 
  TBL_NAME
GROUP BY particular

一般来说，这个文档（oracle按功能分组）可能很有用：http://docs.oracle.com/cd/E17952_01/refman-5.5-en/group-by-functions.html#function_max
