Question

我正在尝试将数据插入到2个表中。客户连接表和设备表。我有一个表单定义“源设备”，“源插槽和端口”和“源FNN”，目标设备值以及客户连接值。

我想在'cust_port'表中插入源和目标系统端口，并将FNNS作为cust_port值和客户连接值插入。

请注意：源值可以为空，目标值可以为空，但不能同时为两者。即，必须至少有源和/或目的地值。如果空白值为空白，我不希望将空值写入设备表（cust_port）。

我尝试了多次插入，但我无法让它工作。

try{

$insert_cust_port="INSERT INTO cust_port (
    system_name, 
    slot_no, 
    port_no, 
    port_fnn
    ) VALUES (
    :system_name_source,  
    :slot_source,
    :port_source    
    :source_fnn
    ),( 
    :system_name_dest,
    :slot_dest,
    :port_dest,
    :dest_fnn   
    )";

$insert_cust_conn="INSERT INTO cust_connections (
    short_name, 
    source_fnn, 
    dest_fnn, 
    service_type,
    ladder_side
    ) VALUES (
    :short_name,  
    :source_fnn, 
    :dest_fnn, 
    :service_type,
    :ladder_side    
    )";

我通过将查询拆分为3个插入解决了这个问题：第一次插入设备的源信息第二个目的地到设备第3位是客户信息。

这样可以轻松检查是否设置了值。我也会将其设置为使用交易。

try{

$insert_cust_port_source="INSERT INTO cust_port (
    system_name, 
    slot_no, 
    port_no, 
    port_fnn
    ) VALUES (
    :system_name,  
    :slot_no,
    :port_no,   
    :port_fnn
    )";

$insert_cust_port_dest="INSERT INTO cust_port (
    system_name, 
    slot_no, 
    port_no, 
    port_fnn
    ) VALUES (  
    :system_name,  
    :slot_no,
    :port_no,   
    :port_fnn   
    )";

$insert_cust_conn="INSERT INTO cust_connections (
    short_name, 
    source_fnn, 
    dest_fnn, 
    service_type,
    ladder_side
    ) VALUES (
    :short_name,  
    :source_fnn, 
    :dest_fnn, 
    :service_type,
    :ladder_side    
    )";


//prepare query for excecution
    $database->query($insert_cust_port_source);

             //bind the parameters
                $database->bind(':system_name', $system_name_source );
                $database->bind(':slot_no', $slot_source );
                $database->bind(':port_no', $port_source );
                $database->bind(':port_fnn', htmlentities($source_fnn) );
// Execute the query
$database->execute(); 


    $database->query($insert_cust_port_dest);

             //bind the parameters

                $database->bind(':system_name', $system_name_dest );
                $database->bind(':slot_no', $slot_dest );
                $database->bind(':port_no', $port_dest );
                $database->bind(':port_fnn', htmlentities($dest_fnn) );         
// Execute the query
$database->execute(); 


    $database->query($insert_cust_conn);

             //bind the parameters
                $database->bind(':short_name', '$short_name' );
                $database->bind(':source_fnn', htmlentities($source_fnn) );
                $database->bind(':dest_fnn', htmlentities($dest_fnn) );
                $database->bind(':service_type', '$service_type' );
                $database->bind(':ladder_side', '$ladder_side' );
// Execute the query
$database->execute();

插入具有多个值的多个表
