Question

我这里有一个奇怪的问题.. 我正在使用codeigniter for PHP，我正在使用一个名为datatables的库。您可以在此链接https://github.com/IgnitedDatatables/Ignited-Datatables/wiki/Function-Reference找到它无论如何，我在以下结构中有以下查询..

 <?php

public function GetQuery(){

 $this->datatables->select('tablessc.Name As region,p.name As name,tabled.test As test,
                                  MAX(CASE WHEN p.id= p.cid and flavor = 2  THEN \'Pass\' ELSE \'Fail\' end) as \'Pass\'
                                  ')
                          ->from('drinks p');
                          $this->datatables->join('tableb ', 'tableb.id=p.pid','inner');
                          $this->datatables->join('tablec','tablec.TerritoryId=tablec.TerritoryId','inner');
                          $this->datatables->join('tabled','tablec.AccountId=tablec.AccountId','inner');
                          $this->datatables->join('tables','d.AccountId = tabless.AccountId ','inner');
                          $this->datatables->join('tablessc','tablesc.Code = p.region and sc.CodeGroup =\'Region\'','inner');

                          $this->datatables->where('region >','0');
                          $this->datatables->where('p.location','0');

                          $this->datatables->group_by('tablessc.Name');
                          $this->datatables->group_by('p.id');
                          $this->datatables->group_by('p.name');
                          $this->datatables->group_by('atabled.test');

echo $this->datatables->generate();
}
?>

这是我得到的错误

[Microsoft][SQL Server Native Client 10.0][SQL Server]Column 'country' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.


SELECT * 
FROM FROM drinks p 
INNER JOIN tableb ON tableb.id=p.pid 
INNER JOIN tablec ON tablec.TerritoryId=tablec.TerritoryId 
INNER JOIN tabled ON tablec.AccountId=tablec.AccountId 
INNER JOIN tables ON d.AccountId = tabless.AccountId 
INNER JOIN tablessc ON tablesc.Code = p.region 
    and sc.CodeGroup ='Region' 
WHERE region > '0' 
    AND p.location = '0' 
GROUP BY tablessc.Name
    ,p.id
    ,p.name
    ,atabled.test

问题在于，当我只想选择我要求的列时，为什么要尝试选择所有列。我得到错误（聚合函数）的原因是因为它试图选择所有列

另请注意，如果我将此查询放在microsoft sql server上的相同结构中，我不会收到错误

SQL试图选择所有列而不是几个
