我使用datatable将数据列为服务器端脚本。
// DB table to use
$table = 'enquiry';
// Table's primary key
$primaryKey = 'enquiry_id';
// Array of database columns which should be read and sent back to DataTables.
// The `db` parameter represents the column name in the database, while the `dt`
// parameter represents the DataTables column identifier. In this case simple
// indexes
$columns = array(
array(
'db' => 'enquiry_date',
'dt' => 0,
'formatter' => function( $d, $row ) {
return date('jS M y', strtotime($d));
}
),
array('db' => 'parent_name', 'dt' => 1),
array('db' => 'child_name', 'dt' => 2),
array('db' => 'mobile', 'dt' => 3),
array('db' => 'emirate', 'dt' => 4),
array('db' => 'remarks', 'dt' => 5),
array('db' => 'enquiry_status_id', 'dt' => 6),
);
// SQL server connection information
$sql_details = array(
'user' => 'root',
'pass' => '',
'db' => 'lsn',
'host' => ''
);
/* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
* If you just want to use the basic configuration for DataTables with PHP
* server-side, there is no need to edit below this line.
*/
require( './server_side/scripts/ssp.class.php' );
echo json_encode(
SSP::simple($_GET, $sql_details, $table, $primaryKey, $columns)
);
这是我的php服务器端脚本,并且对于单个表工作非常好。
我希望在列出表格行时加入两个表格。但我找不到任何连接表或编写自定义查询的选项。
如果有可能,我怎么能加入表?

这里有两个表keyid相同的字段和其他字段提取
$sql_t="SELECT tabkey.keyid, table1.value, table2.value
FROM
(SELECT table1.keyid FROM table1
UNION
SELECT table2.keyid FROM table2) as tabkey
LEFT JOIN
table1 on tabkey.keyid = table1.keyid
LEFT JOIN
table2 on tabkey.keyid = table2.keyid;";

第1步:打开ssp.class.php
第2步:找到这一行..... FROM' $ table'
步骤3:删除单引号.... FROM $ table
步骤4:对另一个做同样的事情..... FROM' $ table' "
FROM $table"
步骤5:您现在可以将子查询添加到$ table
示例$ table ="(从my_list join中选择*)&#34 ;;
第6步:庆祝=)
