获取帖子的所有 id 我通过自定义查询添加它

Question

现在我有这个查询：

$query1 =  "
INSERT INTO wpr9_posts
(post_date
, post_content
, post_title
, post_status
, post_name
, post_type)  
SELECT '2020-08-28 18:30:43'
     , image
     , name
     , 'publish'
     , id
     , 'post' 
  FROM play
 WHERE catid = 863
" ;
$loopids = $wpdb->query($wpdb->prepare($query1));

这个查询插入114行，添加到wpr9_posts表后，我需要将所有ids添加到tis表中才能添加到wpr9_postmeta表中，

$query2 =  "INSERT INTO wpr9_postmeta ( `post_id`,`meta_key`,`meta_value` ) 
SELECT '".$id1."', 'mp3url',`image` FROM `play` WHERE `catid` = '863'" ;
$wpdb->query(
    $wpdb->prepare($query2)
);

此查询仅添加一行，因为我使用以下方法仅获得一个 id：

$id1 =  $wpdb->insert_id;

所以，我需要将所有 id 插入 wpr9_postmeta

Answer 1

SQL server 中的@@IDENTITY、SCOPE_IDENTITY()、IDENT_CURRENT(‘table’)等查询执行后有多个获取插入的id。

INSERT INTO wpr9_posts (...) VALUES (...)
SET @LASTID = @@IDENTITY

INSERT INTO wpr9_posts (...) VALUES (...)
SET @LASTID = SCOPE_IDENTITY()

SET @LASTID = IDENT_CURRENT('dbo.wpr9_posts')

至于Mysql。很难工作。您可以声明一个开始游标和结束游标，在它们之间，您可以按以下方式运行查询

    declare start_pk int;
    declare end_pk int;

    set start_pk = last_insert_id(); -- lets say 100
    
    INSERT INTO wpr9_posts
(post_date
, post_content
, post_title
, post_status
, post_name
, post_type)  
SELECT '2020-08-28 18:30:43'
     , image
     , name
     , 'publish'
     , id
     , 'post' 
  FROM play
 WHERE catid = 863

    set end_pk = last_insert_id(); -- lets say 200
    -- result any ids in from 100 to 200 is your inserted id
