Question

我有以下问题：

INSERT INTO StatisticalConsultationAgreement VALUES (
   queryType, entityCode, entityType, queryClass,queryTables,period, 
   COUNT(queryClass),  SUM(numberRecords),  SUM(recordsFound),
   SUM(NorecordsFound), NOW(), 'system');
SELECT
   MONTH(EndDateTimeProcessing),YEAR(EndDateTimeProcessing),
   entityType,
   entityCode,
   queryType,
   queryClass,
   EndDateTimeProcessing as period
FROM agreementFile
WHERE 
  MONTH(EndDateTimeProcessing)=MONTH(DATE_SUB( CURDATE(), INTERVAL 1 MONTH )) 
  AND YEAR(EndDateTimeProcessing)=YEAR(CURDATE())
GROUP BY entityType,entitycode,queryType, queryClass;

当我运行查询时，我得到了下一个错误：

Error code 1111, SQL state HY000: Invalid use of group function
Line 1, column 1

Executed successfully in 0,002 s.
Line 5, column 2

为什么选择这个？

如何解决？

Answer 1

您没有对EndDateTimeProcessing进行分组，当您尝试执行插入操作时，无法确定应从分组行中选择哪个EndDateTimeProcessing值。解决方案是将其添加到组子句中：

 GROUP BY entityType,entitycode,queryType, queryClass, EndDateTimeProcessing;

或者您使用函数组作为MAX（），MIN（）等

最好的问候

正如Gordon Linoff所说，你也在将查询与INSERT混合，一切都应该通过查询得到。

正确的语法应该是：

INSERT INTO StatisticalConsultationAgreement
SELECT
   'queryType', --I don't know what is the query type so i put it on single quote
   entityCode,
   entityType,
   queryClass,
   queryTables,
   MAX(EndDateTimeProcessing), --Period put on group function MAX, but it cant be grouped below or put into another group function
   COUNT(queryClass),  --
   SUM(numberRecords), --  ASUMING THOSE ARE COLUMNS IN  agreementFile
   SUM(recordsFound),  --
   SUM(NorecordsFound),-- 
   NOW(),
   'system'
FROM agreementFile
WHERE 
  MONTH(EndDateTimeProcessing)=MONTH(DATE_SUB( CURDATE(), INTERVAL 1 MONTH )) 
  AND YEAR(EndDateTimeProcessing)=YEAR(CURDATE())
GROUP BY entityType,entitycode,queryType, queryClass;

查询字段MONTH(EndDateTimeProcessing),YEAR(EndDateTimeProcessing),已删除，因为我不知道应该在哪里

您在values中混合了select语句和insert语句。您只需要select。这是我对你想要的最好的猜测：

INSERT INTO StatisticalConsultationAgreement 
    SELECT queryType, entityCode, entityType, queryClass,queryTables,period, 
           COUNT(queryClass),  SUM(numberRecords),  SUM(recordsFound),
           SUM(NorecordsFound), NOW(), 'system'
    FROM agreementFile
    WHERE MONTH(EndDateTimeProcessing)=MONTH(DATE_SUB( CURDATE(), INTERVAL 1 MONTH )) AND
          YEAR(EndDateTimeProcessing)=YEAR(CURDATE())
    GROUP BY entityType, entitycode, queryType, queryClass;

但是，您还应在StatisticalConsultationAgreement声明中列出insert的列名。

SQL INSERT INTO SELECT语句无效使用组函数
