Php Zend DB无法模拟MS SQL的限制和偏移量

我正在使用Zend Framework 1.12访问MSSQL 2008服务器。我使用FreeTDS作为数据库驱动程序

我使用Zend_Db生成以下查询

 $obj_sel = $obj_db
          -> select ()
          -> from (array ('ps' => 'ProductStock'), array ('PLU', 'stock' => 'SUM(ps.stock)'))
          -> join (array ('pc' => 'ProductCatalogue'), 'ps.PLU = pc.PLU', NULL)
          -> join (array ('gl' => 'Gemini_Location'), 'ps.Location = gl.LocationID', array ('LocationID'))
          -> where ('ps.status = 1')
          -> where ('ps.PLU IS NOT NULL');
           > where ('pc.rootPLU >= ?', $this -> int_start_rootplu);
          -> group ('ps.PLU')
          -> group ('gl.LocationID')
          -> order (array ('ps.PLU', 'gl.LocationID'));

如果我运行并执行它，我会得到一个运行良好且正确的查询

SELECT "ps"."PLU", SUM(ps.stock) AS "stock", "gl"."LocationID" FROM "ProductStock" AS "ps"
 INNER JOIN "ProductCatalogue" AS "pc" ON ps.PLU = pc.PLU
 INNER JOIN "Gemini_Location" AS "gl" ON ps.Location = gl.LocationID WHERE (ps.status = 1) AND (ps.PLU IS NOT NULL) AND (pc.rootPLU >= 93838) GROUP BY "ps"."PLU",
    "gl"."LocationID" ORDER BY "ps"."PLU" ASC, "gl"."LocationID" ASC

但当我尝试向查询添加限制或偏移量时，如下所示：

 $obj_sel = $obj_db
          -> select ()
          -> from (array ('ps' => 'ProductStock'), array ('PLU', 'stock' => 'SUM(ps.stock)'))
          -> join (array ('pc' => 'ProductCatalogue'), 'ps.PLU = pc.PLU', NULL)
          -> join (array ('gl' => 'Gemini_Location'), 'ps.Location = gl.LocationID', array ('LocationID'))
          -> where ('ps.status = 1')
          -> where ('ps.PLU IS NOT NULL');
           > where ('pc.rootPLU >= ?', $this -> int_start_rootplu);
          -> group ('ps.PLU')
          -> group ('gl.LocationID')
          -> order (array ('ps.PLU', 'gl.LocationID'))
          -> limit (1000,2000);

我得到了SQL server拒绝执行的以下查询

SELECT * FROM (SELECT TOP 1000 * FROM (SELECT TOP 3000 "ps"."PLU", SUM(ps.stock) AS "stock", "gl"."LocationID" FROM "ProductStock" AS "ps"
 INNER JOIN "ProductCatalogue" AS "pc" ON ps.PLU = pc.PLU
 INNER JOIN "Gemini_Location" AS "gl" ON ps.Location = gl.LocationID WHERE (ps.status = 1) AND (ps.PLU IS NOT NULL) AND (pc.rootPLU >= 93838) GROUP BY "ps"."PLU",
    "gl"."LocationID" ORDER BY "ps"."PLU" ASC, "gl"."LocationID" ASC) AS inner_tbl ORDER BY "ps"."PLU" , "gl"."LocationID" DESC) AS outer_tbl ORDER BY "ps"."PLU" , "gl"."LocationID" asc

我得到以下错误：

SQLSTATE[HY000]：常规错误：4104常规SQL Server错误：检查来自SQL Server的消息[4104]（严重性16）[（空）]

我对MSSQL不像对MySQL或Postgres那么熟悉，所以我不得不假设顶级技术是正确的。然而，很明显，这里生成的SQL Zend DB并不正确

这是Zend DB中的已知问题吗？如果是这样，我如何解决它

ZF 1无法在SQL Server上正确实现分页，尽管ZF 2可以

我通过子类化Zend_Db_Adapter_Pdo_Mssql解决了这个问题：

class My_Zend_Db_Adapter_Pdo_Mssql extends Zend_Db_Adapter_Pdo_Mssql
{
    /**
     * @see Zend_Db_Adapter_Pdo_Mssql::limit()
     */
    public function limit($sql, $count, $offset = 0)
    {
        $count = intval($count);
        if ($count <= 0) {
            /** @see Zend_Db_Adapter_Exception */
            require_once 'Zend/Db/Adapter/Exception.php';
            throw new Zend_Db_Adapter_Exception('count parameter invalid: ' . $count);
        }

        $offset = intval($offset);
        if ($offset < 0) {
            /** @see Zend_Db_Adapter_Exception */
            require_once 'Zend/Db/Adapter/Exception.php';
            throw new Zend_Db_Adapter_Exception('offset parameter invalid: ' . $count);
        }

        if (0 == $offset) {
            $sql = preg_replace('/^SELECT\s+(DISTINCT\s)?/i', 'SELECT $1TOP ' . ($count+$offset) . ' ', $sql);
            return $sql;
        }

        $selectStart = stripos($sql, 'SELECT');
        $fromStart = stripos($sql, 'FROM');

        $orderby = stristr($sql, 'ORDER BY');

        if ($orderby === false) {
            $orderby = 'ORDER BY (SELECT 1)';
        }

        $sql = rtrim(str_replace($orderby, '', $sql));

        $selectParams = trim(substr($sql, $selectStart + 6, $fromStart - $selectStart - 6));
        $selectParams .= ', ROW_NUMBER() OVER (' . $orderby . ') AS [ZEND_ROW_NUMBER]';

        $sql = substr($sql, 0, $selectStart + 6) . ' ' . $selectParams . ' ' . substr($sql, $fromStart);

        $outerSql = 'SELECT * FROM (' . $sql . ') AS [ZEND_OFFSET_EMULATION]'
                  . ' WHERE [ZEND_OFFSET_EMULATION].[ZEND_ROW_NUMBER] BETWEEN '
                  . ($offset + 1) . ' AND '
                  . ($offset + $count)
                  . ' ORDER BY [ZEND_ROW_NUMBER] ASC';

        return $outerSql;
    }
}
