not use GROUP by for special processing, the default classification is to set the entire result to a class.Select stat, counter (*) zip_count from zip_codes group by state; ST ZIP_COUNT -- --------- AK 360AL 1212AR 1309AZ 768CA 3982
In this example, we use the state field for classification. If we want to sort the results BY zip_codes, we can use the order by statement. The order by clause can use columns or group functions.Select stat, counter (*) zip_count from zip_codes group by state order

BKJIA Editor's note: The latest device on the Nokia MeeGo platform has been exposed recently, but it is probably a tablet. This article is the latest MeeGo Core 1.1.90 test report of the current online version. The pass rate of MeeGo Core 1.1.90 is 100%, and the overall quality remains stable.
The Obexd and telepathy-Qt4 software packages were updated and no other issues were found during the test.
