Expression #35 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'snowbear_data_analysis.f.的解决方法

这个错误通常在使用GROUP BY子句的SQL查询中出现,原因是SELECT语句中的某些列不在GROUP BY子句中,也没有被聚合函数(如SUM,MAX,MIN等)所处理。为了解决这个问题,你可以将SELECT语句中的所有非聚合列添加到GROUP BY子句中,或者使用聚合函数对这些列进行计算。
例如,如果你的查询如下所示:
```
SELECT col1, col2, COUNT(*)
FROM my_table
GROUP BY col1
```
并且出现了 "Expression #2 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'my_table.col2'" 的错误提示。那么你需要将SELECT语句修改为:
```
SELECT col1, col2, COUNT(*)
FROM my_table
GROUP BY col1, col2
```
或者使用聚合函数将col2列进行处理:
```
SELECT col1, MAX(col2), COUNT(*)
FROM my_table
GROUP BY col1
```
这样就可以解决这个错误了。

Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'kaixi_homecare.a.id'
这个错误是由于您在使用GROUP BY子句时,SELECT语句中的列不一致导致的。在GROUP BY子句中,您必须指定所有不聚合的列。在这种情况下,您需要将a.id列添加到GROUP BY子句中:
SELECT a.id, other_columns
FROM your_table_name AS a
GROUP BY a.id, other_columns
请注意,other_columns是您查询中的其他列。确保在GROUP BY子句中包含所有这些列,以解决此错误。
Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column
引用\[1\]、\[2\]和\[3\]都是关于MySQL报错的信息,其中提到了"Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column"的错误。这个错误是由于在使用GROUP BY子句进行分组查询时,SELECT列表中的某些列没有在GROUP BY子句中出现,并且这些列也没有被聚合函数包含,导致不兼容的错误。这个错误通常是由于MySQL的sql_mode设置为only_full_group_by引起的。解决这个错误的方法是要么将SELECT列表中的列添加到GROUP BY子句中,要么将这些列用聚合函数进行处理,以确保查询的正确性。
