我在下面有以下代码，我相信它会加载数据库。至少如果我在database.php配置中更改某些内容（如主机名字符串），它将会死亡。但是，我可以执行sql。这个确切的SQL在命令行中工作正常。我只是想弄清楚错误是奇怪的，它在命令行中找不到表。
my_ci_code.php
db = $this->load->database('eapplication',TRUE); <-- this is ok, doesnt die
$qry_string="SELECT dbo.EAPPLICATION.DATE_COA FROM dbo.EAPPLICATION WHERE (dbo.EAPPLICATION.CODE IN (2, 3))";
$query = $this->db->query($qry_string); <-- dies here
echo "number of rows:" . $query->num_rows();
database.php中
$db['eapplication']['hostname'] = 'Driver={SQL Server Native Client 11.0};Server=10.3.33.333;Database=eapplicationDB;';
$db['eapplication']['username'] = 'userA'; //'';
$db['eapplication']['password'] = 'password'; //'';
$db['eapplication']['database'] = 'eapplicationDB'; //'';
$db['eapplication']['dbdriver'] = 'odbc';
$db['eapplication']['dbprefix'] = '';
$db['eapplication']['pconnect'] = FALSE;
$db['eapplication']['db_debug'] = TRUE;
$db['eapplication']['cache_on'] = FALSE;
$db['eapplication']['cachedir'] = '';
$db['eapplication']['char_set'] = 'utf8';
$db['eapplication']['dbcollat'] = 'utf8_general_ci';
$db['eapplication']['swap_pre'] = '';
$db['eapplication']['autoinit'] = TRUE;
$db['eapplication']['stricton'] = FALSE;
