參數索引超出範圍（1>參數數目，爲0）。 Mysql vs Java

Question

在mysql中運行以下查詢時，它工作得很好。

SELECT 
    a.feed_date, a.partner_name, 
    SUM(a.count) as InputCount, 
    SUM(CASE when (b.count is null) then 0 else b.count end) as OutputCount 
FROM 
(SELECT year,week,partner_name, feed_date, count 
    FROM op_dev.op_stats 
    WHERE partner_name IN ('xyz, INC.','abc') 
    AND mkt_elig_cd='Y' 
    AND rel_grp_type_no='00000' 
    AND feed_type='SellerChar') AS A 
LEFT OUTER JOIN 
    (SELECT year,week,feed_date, partner_name, count 
    FROM opt_dev.op_stats 
    WHERE partner_name IN ('xyz, INC.','abc') 
    AND mkt_elig_cd='Y' 
    AND rel_grp_type_no='00000' 
    AND feed_type='MSF') AS B 
ON A.partner_name = B.partner_name 
    AND A.year=B.year 
    AND A.week=B.week 
GROUP BY A.week,A.year; 

然而，當我使用相同的查詢字符串，並把它通過Java代碼，它給我以下錯誤：

java.sql.SQLException: Parameter index out of range (1 > number of parameters, which is 0). 

可有人請幫我指出是什麼導致這個問題。

Answer 1

貌似你試圖執行查詢，並指定參數（檢查java和休眠），但查詢沒有參數。

Answer 2

GROUP BY子句必須包含選定的列。如果沒有選擇列，GROUP BY子句可以使用任何列。 你可以試試這個：

SELECT partner_name, feed_date, 
    SUM(CASE WHEN feed_type='SellerChar' THEN count ELSE 0 END) OVER(PARTITION BY year,week,feed_type) AS InputCount, 
    SUM(CASE WHEN feed_type='MSF' THEN count ELSE 0 END) OVER(PARTITION BY year,week,feed_type) AS OutputCount 
FROM op_dev.op_stats 
WHERE partner_name IN ('xyz, INC.','abc') 
    AND mkt_elig_cd='Y' 
    AND rel_grp_type_no='00000' 
    AND (feed_type='SellerChar' OR feed_type='MSF')
