如何在SQL甲骨文

Question

行合併我的表像下面

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

但我希望得到像下面

PARTICULAR OPENING TRANSACTION ENDING 
Expense  5456456 1232131 123123 

是否有可能的信息，以實現這一目標使用SQL查詢？

Answer 1

這聽起來像你只是想

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

Answer 2

假設交易，開場和結束時都大於零的只是一排，下面將工作

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

在一般情況下，本文檔（的oracle組功能）可能是有用的：http://docs.oracle.com/cd/E17952_01/refman-5.5-en/group-by-functions.html#function_max

Answer 3

你想SUM它，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
