F3区分大小写映射错误

Question

我目前正在使用来自脱脂框架映射器与MS SQL服务器：

$reports = new DB\SQL\Mapper($f3->get('DB'),'Reports'); 

我碰到下面的错误日志：

PDOStatement对象：[微软] [用于SQL Server的ODBC驱动程序11] [SQL Server]无效的对象名称'information_schema.columns'。

[C:/wamp32/www/lib/base.php:2032] Base->error(500,'PDOStatement: [Microsoft] 
[ODBC Driver 11 for SQL Server][SQL Server]Invalid object name 'information_schema.columns'.') 
[C:/wamp32/www/lib/db/sql.php:339] DB\SQL->exec('SELECT c.column_name AS field,c.data_type AS type,c.column_default AS defval,c.is_nullable AS nullable,t.constraint_type AS pkey FROM information_schema.columns AS c LEFT OUTER JOIN information_schema.key_column_usage AS k ON c.table_name=k.table_name AND c.column_name=k.column_name AND c.table_schema=k.table_schema AND c.table_catalog=k.table_catalog LEFT OUTER JOIN information_schema.table_constraints AS t ON k.table_name=t.table_name AND k.constraint_name=t.constraint_name AND k.table_schema=t.table_schema AND k.table_catalog=t.table_catalog WHERE c.table_name='Reports';',NULL,60) 

它提取的SELECT查询，并试图直接在服务器上运行它，并意识到这是一个区分大小写问题，因为当我运行它大写正常工作。

我的问题是，我无法找到如何绕过此或强制大写的查询。文档here没有提到这样的事情。

感谢您的帮助！

这是lib/db/sql.php文件中的解决方案。

您添加以下支援引擎的$ CMD阵列，在该模式功能：

'sqlsrv'=>array('SELECT '. 
        'C.COLUMN_NAME AS FIELD,'. 
        'C.DATA_TYPE AS TYPE,'. 
        'C.COLUMN_DEFAULT AS DEFVAL,'. 
        'C.IS_NULLABLE AS NULLABLE,'. 
        'T.CONSTRAINT_TYPE AS PKEY '. 
       'FROM INFORMATION_SCHEMA.COLUMNS AS C '. 
       'LEFT OUTER JOIN '. 
        'INFORMATION_SCHEMA.KEY_COLUMN_USAGE AS K '. 
        'ON '. 
         'C.TABLE_NAME=K.TABLE_NAME AND '. 
         'C.COLUMN_NAME=K.COLUMN_NAME AND '. 
         'C.TABLE_SCHEMA=K.TABLE_SCHEMA '. 
         ($this->dbname? 
          ('AND C.TABLE_CATALOG=K.TABLE_CATALOG '):''). 
       'LEFT OUTER JOIN '. 
        'INFORMATION_SCHEMA.TABLE_CONSTRAINTS AS T ON '. 
         'K.TABLE_NAME=T.TABLE_NAME AND '. 
         'K.CONSTRAINT_NAME=T.CONSTRAINT_NAME AND '. 
         'K.TABLE_SCHEMA=T.TABLE_SCHEMA '. 
         ($this->dbname? 
          ('AND K.TABLE_CATALOG=T.TABLE_CATALOG '):''). 
       'WHERE '. 
        'C.TABLE_NAME='.$this->quote($table). 
        ($this->dbname? 
         (' AND C.TABLE_CATALOG='. 
          $this->quote($this->dbname)):''). 
       ';', 
       'FIELD','TYPE','DEFVAL','NULLABLE','YES','PKEY','PRIMARY KEY'), 

希望这将有助于。
