Question

SELECT 
    dm.DISTRICT_NAME ,      
    od.REGULAR_WORKERS_COUNT,
    od.DAILY_OR_CASUAL_WORKERS_COUNT,
    od.CONTRACT_WORKERS_COUNT,
    od.TOTAL_COUNT
FROM
    ORG_DETAILS od with (NOLOCK)
INNER JOIN 
    DISTRICT_MASTER dm with (NOLOCK) ON od.DISTRICT_ID = dm.DISTRICT_ID
GROUP BY
    dm.district_name

我有这个代码，我希望用zone_name对表进行分组。我收到了一个错误。

错误讯息：

列'ORG_DETAILS.REGULAR_WORKERS_COUNT'在选择列表中无效，因为它不包含在聚合函数或GROUP BY子句中。

Answer 1

你应该试试这个： -

SELECT 
    dm.DISTRICT_NAME ,      
    COUNT(od.REGULAR_WORKERS_COUNT),
    COUNT(od.DAILY_OR_CASUAL_WORKERS_COUNT),
    COUNT(od.CONTRACT_WORKERS_COUNT),
    COUNT(od.TOTAL_COUNT)
FROM 
    ORG_DETAILS od with (NOLOCK)
INNER JOIN 
    DISTRICT_MASTER dm with (NOLOCK) ON od.DISTRICT_ID = dm.DISTRICT_ID
GROUP BY 
    dm.district_name

Answer 2

SELECT 
    dm.DISTRICT_NAME ,      
    sum(od.REGULAR_WORKERS_COUNT),
    sum(od.DAILY_OR_CASUAL_WORKERS_COUNT),
    sum(od.CONTRACT_WORKERS_COUNT),
    sum(od.TOTAL_COUNT)
FROM 
    ORG_DETAILS od with (NOLOCK)
INNER JOIN 
    DISTRICT_MASTER dm with (NOLOCK) ON od.DISTRICT_ID = dm.DISTRICT_ID
GROUP BY 
    dm.district_name

group by子句不起作用
