HSQL视图错误：表达式不在聚合列或分组列中

我在hsql中有一个创建视图查询，但每当我运行它时，它都会抛出以下错误：

表达式不在聚合列或分组列中：AGV.ID

我知道如果没有任何聚合表达式AVG、SUM、MIN、MAX，GROUP BY将无法工作，但我不知道如何修复我的查询。。 因为每个记录都需要按manifestID值分组

基本上，我试图通过组合3组select查询来创建一个视图

我尝试使用distinct，但运气不佳，因为如果我选择了多个列，它将不起作用。 这个查询在MYSQL中运行良好

我的问题是：

CREATE VIEW local_view_event_manifest(
        manifest_id,
        eventId, 
        eventType, 
        eventDate,

@弗雷德。。。 谢谢你的详细解释。。关于你的建议，我已经试过了。。但不知何故，我得到了这个错误：

错误：找不到表：语句[SELECT TABL_B.*FROM SELECT DISTINCT manifest_id FROM local.local_AGGREGATION_EVENT_manifest_DATA TABL_A]中的TABL_B错误代码：-22

以下是我的疑问：

SELECT TABL_B.* FROM (SELECT DISTINCT manifest_id FROM "local".local_AGGREGATION_EVENT_MANIFEST_DATA) TABL_A
LATERAL JOIN 
( SELECT 
    agm.manifest_id AS manifest_id,
    agv.id AS eventId,
    'AGGREGATION_EVENT' AS eventType,
    agv.event_time AS eventDate,
    md.manifest_id AS manifestID,
    agv.business_step_code AS businessStepStr,
    md.manifest_version AS manifestVersion,
    md.external_location AS externalLocation,
    md.remark AS remark,
    epc.code as epcCode,
    bloc.location_code as locationCode
    FROM

    AND bloc.id=agv.business_location_id
    AND agv_epc.epc_id=epc.id AND manifest_id = TABL_A.manifest_id  LIMIT 1 ) TABL_B

谢谢@fredt。。我注意到逗号的问题，并且已经添加到我的查询中。我也试着去掉连接词。但还是犯了同样的错误

ERROR: Table not found in statement [SELECT TABL_B.* FROM (SELECT
DISTINCT MANIFEST_ID FROM "local".local_AGGREGATION_EVENT_MANIFEST_DATA)
AS TABL_A, LATERAL] Error Code: -22

对于HSQLDB 2.2.x或更高版本：

使用GROUP BY时，所有选定的列都必须位于GROUP BY列表中，聚合列除外。在您的示例中，GROUPBY列表应该包含11列，而不是一列

您可以使用DISTINCT，如在SELECT DISTINCT COL1、COLB、COLC。。。没有分组。DISTINCT是一种快捷方式，用于对选择列表中的所有列进行分组

通常，GROUP BY意味着查询应该只为GROUP BY列表中的每一列值组合返回一行。允许使用聚合，因为它们可以将多行中的值合并为一个值

现在，如果您包括GROUPBY列表中的所有列，并且结果中有多行具有相同的manifestID值，则意味着您不能仅根据manifestID进行分组

更新：您对MySQL的查询结果表明，这方面的要求不是很严格。manifestId=BHBHBH的行超过20行，其他列中的值不相同。但是MySQL会随机返回其中一行。根据其他数据库（包括HSQLDB）支持的SQL标准，GROUPBY不是这样工作的。请参见MySQL专家的博客：

如果需要类似于MySQL输出的内容，则需要如下查询：

SELECT TABL_B.* FROM (SELECT DISTINCT manifestID FROM "local".local_AGGREGATION_EVENT_MANIFEST_DATA) TABL_A,
LATERAL 
( [YOUR SELECT STATEMENT WITHOUT GROUP BY] AND manifestID = TABL_A.manifestID  LIMIT 1 ) TABL_B

首先尝试使用视图中的一个选择，然后应用于其余选择

您可以通过在限制1之前按列名称添加订单来选择返回哪一行。

您可以发布一些具有预期结果的示例数据吗？hi Madhivan。。我已经添加了查询结果快照…我已经在顶部添加了我的预期结果快照：请参考此链接[通过分组查询结果]。感谢所有。。。很抱歉我没有及时回复。。我设法解决了它。。你们是对的。。我从hsql查询中删除了GROUPBY子句，并将select查询修改为具有DISTINCT属性
