我正在尝试转换这个:http://www.datatables.net/examples/server_side/server_side.html
对于使用SQLSRV,这是我到目前为止的代码:
<?php
ini_set("memory_limit",-1);
define('IN_INDEX', 1);
require_once 'config.php';
$aColumns = array( 'ID', 'CardNumber');
/* Indexed column (used for fast and accurate table cardinality) */
$sIndexColumn = "ID";
/* DB table to use */
$sTable = "ActivityLog";
/*
* Paging
*/
$sLimit = "";
if ( isset( $_GET['iDisplayStart'] ) && $_GET['iDisplayLength'] != '-1' )
{
$sLimit = "OFFSET ".$_GET['iDisplayStart']." ROWS
FETCH NEXT ".$_GET['iDisplayLength']." ROWS ONLY ";
}
/*
* Ordering
*/
if ( isset( $_GET['iSortCol_0'] ) )
{
$sOrder = "ORDER BY ";
for ( $i=0 ; $i<intval( $_GET['iSortingCols'] ) ; $i++ )
{
if ( $_GET[ 'bSortable_'.intval($_GET['iSortCol_'.$i]) ] == "true" )
{
$sOrder .= $aColumns[ intval( $_GET['iSortCol_'.$i] ) ]."
".addslashes( $_GET['sSortDir_'.$i] ) .", ";
}
}
$sOrder = substr_replace( $sOrder, "", -2 );
if ( $sOrder == "ORDER BY" )
{
$sOrder = "";
}
}
/*
* Filtering
* NOTE this does not match the built-in DataTables filtering which does it
* word by word on any field. It's possible to do here, but concerned about efficiency
* on very large tables, and MySQL's regex functionality is very limited
*/
$sWhere = "";
if ( $_GET['sSearch'] != "" )
{
$sWhere = "WHERE (";
for ( $i=0 ; $i<count($aColumns) ; $i++ )
{
$sWhere .= $aColumns[$i]." LIKE '%".addslashes( $_GET['sSearch'] )."%' OR ";
}
$sWhere = substr_replace( $sWhere, "", -3 );
$sWhere .= ')';
}
/* Individual column filtering */
for ( $i=0 ; $i<count($aColumns) ; $i++ )
{
if ( $_GET['bSearchable_'.$i] == "true" && $_GET['sSearch_'.$i] != '' )
{
if ( $sWhere == "" )
{
$sWhere = "WHERE ";
}
else
{
$sWhere .= " AND ";
}
$sWhere .= $aColumns[$i]." LIKE '%".addslashes($_GET['sSearch_'.$i])."%' ";
}
}
/*
* SQL queries
* Get data to display
*/
$sQuery = "
SELECT COUNT (*) OVER () AS ROW_COUNT ".str_replace(" , ", " ", implode(", ", $aColumns))."
FROM $sTable
$sWhere
$sOrder
$sLimit
";
$rResult = sqlsrv_query( $sQuery ) or die(print_r(sqlsrv_errors()));
/* Data set length after filtering */
$sQuery = "
SELECT @@ROWCOUNT
";
$rResultFilterTotal = sqlsrv_query( $sQuery ) or die(print_r(sqlsrv_errors()));
$aResultFilterTotal = sqlsrv_fetch_array($rResultFilterTotal);
$iFilteredTotal = $aResultFilterTotal[0];
/* Total data set length */
$sQuery = "
SELECT COUNT(".$sIndexColumn.")
FROM $sTable
";
$rResultTotal = sqlsrv_query( $sQuery ) or die(print_r(sqlsrv_errors()));
$aResultTotal = sqlsrv_fetch_array($rResultTotal);
$iTotal = $aResultTotal[0];
/*
* Output
*/
$output = array(
"sEcho" => intval($_GET['sEcho']),
"iTotalRecords" => $iTotal,
"iTotalDisplayRecords" => $iFilteredTotal,
"aaData" => array()
);
while ( $aRow = sqlsrv_fetch_array( $rResult ) )
{
$row = array();
for ( $i=0 ; $i<count($aColumns) ; $i++ )
{
if ( $aColumns[$i] == "version" )
{
/* Special output formatting for 'version' column */
$row[] = ($aRow[ $aColumns[$i] ]=="0") ? '-' : $aRow[ $aColumns[$i] ];
}
else if ( $aColumns[$i] != ' ' )
{
/* General output */
$row[] = $aRow[ $aColumns[$i] ];
}
}
$output['aaData'][] = $row;
}
echo json_encode( $output );
?>
运行此程序时,我收到此错误:
数组 ( [0] => 数组 ( [0] => IMSSP [SQLSTATE] =>IMSSP [1] => -14 [代码] => -14 [2] => 向sqlsrv_query传递了无效参数。 [消息] => 向sqlsrv_query传递了无效的参数。) ) 1
以下是我与 SQL Server 2008 建立连接的方式:
$pdo = new PDO("sqlsrv:Server=$DB_HOST;Database=$DB_DBNAME", $DB_USER, $DB_PWD);
我不太确定实际问题是什么,也看不到要检查的行号。
编辑:我正在使用的 HTML:
<table id="mainTable" class="table table-hover table-bordered table-striped table-condensed" >
<thead>
<tr>
<th>ID</th>
<th>CardNumber</th>
</tr>
</thead>
<tfoot>
<tr>
<th>ID</th>
<th>CardNumber</th>
</tr>
</tfoot>
</table>
</div>
</div>
</div>
<script type="text/javascript" charset="utf-8">
$(document).ready(function() {
$('#mainTable').dataTable( {
"bProcessing": true,
"bServerSide": true,
"sAjaxSource": "http://localhost/datatables.php"
} );
} );
</script>
最后,我在Michael Berkowski的帮助下修复了它
这是我的最终代码:

$serverName = ""; //serverNameinstanceName
$connectionInfo = array( "Database"=>"", "UID"=>"", "PWD"=>"");
$conn = sqlsrv_connect( $serverName, $connectionInfo);
