我正在使用数据表v 1.10.19当我使用以下内容时,该组通过破坏分页并仅显示一页。
$where = "recipient='".$recipient."' AND grouped='' GROUP BY id DESC";
echo json_encode(
SSP::complex( $_GET, $sql_details, $table, $primaryKey, $columns, null, $where )
);
这是复杂的功能:
static function complex ( $request, $conn, $table, $primaryKey, $columns, $whereResult=null, $whereAll=null )
{
$bindings = array();
$db = self::db( $conn );
$localWhereResult = array();
$localWhereAll = array();
$whereAllSql = '';
// Build the SQL query string from the request
$limit = self::limit( $request, $columns );
$order = self::order( $request, $columns );
$where = self::filter( $request, $columns, $bindings );
$whereResult = self::_flatten( $whereResult );
$whereAll = self::_flatten( $whereAll );
if ( $whereResult ) {
$where = $where ?
$where .' AND '.$whereResult :
'WHERE '.$whereResult;
}
if ( $whereAll ) {
$where = $where ?
$where .' AND '.$whereAll :
'WHERE '.$whereAll;
$whereAllSql = 'WHERE '.$whereAll;
}
// Main query to actually get the data
$data = self::sql_exec( $db, $bindings,
"SELECT `".implode("`, `", self::pluck($columns, 'db'))."`
FROM `$table`
$where
$order
$limit "
);
// Data set length after filtering
$resFilterLength = self::sql_exec( $db, $bindings,
"SELECT COUNT(`{$primaryKey}`)
FROM `$table`
$where"
);
if(empty($resFilterLength)){$recordsFiltered="['1','2']";}else{
$recordsFiltered = $resFilterLength[0][0];
}
//$recordsFiltered = $resFilterLength[0][0];
// Total data set length
$resTotalLength = self::sql_exec( $db, $bindings,
"SELECT COUNT(`{$primaryKey}`)
FROM `$table` ".
$whereAllSql
);
if(empty($resTotalLength)){$recordsTotal="['1','2']";}else{
$recordsTotal = $resTotalLength[0][0];
}
//$recordsTotal = $resTotalLength[0][0];
/*
* Output
*/
return array(
"draw" => isset ( $request['draw'] ) ?
intval( $request['draw'] ) :
0,
"recordsTotal" => intval( $recordsTotal ),
"recordsFiltered" => intval( $recordsFiltered ),
"data" => self::data_output( $columns, $data )
);
}
问题是应该添加/更改哪些内容以添加对GROUP BY
子句的支持但是,我可以使用以下属性的数据表来显示GROUP BY DESC但是如果它是服务器端则会更好:
'order': [4, 'desc'],
更新:
由@scaisEdge建议:
对于第一个建议我改变了以下内容:
// Data set length after filtering
$resFilterLength = self::sql_exec( $db, $bindings,
"SELECT COUNT(`{$primaryKey}`)
FROM `$table`
$where"
);
至
// Data set length after filtering
$resFilterLength = self::sql_exec( $db, $bindings,
"SELECT COUNT(`{$primaryKey}`)
FROM `$table`".
$where
);
第二个建议:
从ssp :: complex json编码语句中删除了GROUP BY子句
// Main query to actually get the data
$data = self::sql_exec( $db, $bindings,
"SELECT `".implode("`, `", self::pluck($columns, 'db'))."`
FROM `$table`
$where
$order
$limit "
);
至
// Main query to actually get the data
$data = self::sql_exec( $db, $bindings,
"SELECT `".implode("`, `", self::pluck($columns, 'db'))."`
FROM `$table`
$where GROUP BY id DESC
$order
$limit "
);
完美的工作:)
两个建议
1)在这段代码中你应该使用字符串连接$ where
$resFilterLength = self::sql_exec( $db, $bindings,
"SELECT COUNT(`{$primaryKey}`)
FROM `$table` " . $where
);
2)似乎你有按组的限制和偏移顺序排序(和ID DESC组错误)
$where = "recipient='".$recipient."' AND grouped=''
GROUP BY id ORDER BY id DESC LIMIT 10 OFFSET 5";
经过上述更改后,可以通过ssp :: complex()语句轻松传递group by
子句或任何其他子句,如下所示:
$where = "recipient='".$recipient."' AND grouped=''";
$extra ='GROUP BY id DESC';
echo json_encode(
SSP::complex( $_GET, $sql_details, $table, $primaryKey, $columns, null, $where, $extra )
);
在SSP.CLASS.PHP的复杂功能中进行更改:
static function complex ( $request, $conn, $table, $primaryKey, $columns, $whereResult=null, $whereAll=null)
至
static function complex ( $request, $conn, $table, $primaryKey, $columns, $whereResult=null, $whereAll=null, $extra=null )
和
// Main query to actually get the data
$data = self::sql_exec( $db, $bindings,
"SELECT `".implode("`, `", self::pluck($columns, 'db'))."`
FROM `$table`
$where
$order
$limit "
);
至
// Main query to actually get the data
$data = self::sql_exec( $db, $bindings,
"SELECT `".implode("`, `", self::pluck($columns, 'db'))."`
FROM `$table`
$where $extra
$order
$limit "
);
