H2 DB - Column must be in Group By list

Question

i am using H2-DB to access static databases...

i have a table which looks like:

COUNTRY     STATE       CITY         LAT     LNG     COUNTRYID      S         


        

Answer 1

MySQL is broken in regards to this. It allows columns in the GROUP BY that are neither in the group by nor arguments to aggregation functions. In fact, the documentation warns against using this extension.

So you can do:

SELECT state
FROM DIYANET
WHERE COUNTRY = 'Germany'
GROUP BY STATE 
ORDER BY STATE;

Or something like this:

SELECT state, min(city), min(lat), . . .
FROM DIYANET
WHERE COUNTRY = 'Germany'
GROUP BY STATE 
ORDER BY STATE;

But SELECT * is not allowed and doesn't really make sense.
