我尝试了两种方法来完成这项工作:
multi_query:
$sql = "START TRANSACTION; INSERT INTO songs (title, disco, deleted) VALUES ('".$titol."', '".$codi."', '0'); SET @last_id = LAST_INSERT_ID(); INSERT INTO lyrics (`lyricsOri`, `lyricsTra`, `song`, `deleted`) VALUES ('".$lyricsO."', '".$lyricsT."', @last_id, 0); COMMIT;";
connection()->multi_query($sql);
和交易:
connection()->begin_transaction(MYSQLI_TRANS_START_READ_ONLY);
connection()->query("START TRANSACTION;");
connection()->query("INSERT INTO songs (title, disco, deleted) VALUES ('".$titol."', '".$codi."', '0');");
connection()->query("SET @last_id = LAST_INSERT_ID();");
connection()->query("INSERT INTO lyrics (`lyricsOri`, `lyricsTra`, `song`, `deleted`) VALUES ('".$lyricsO."', '".$lyricsT."', @last_id, 0);");
connection()->query("COMMIT;");
connection()->commit();
connection()->close();
所有记录均记录良好,但歌词表上的歌曲列除外,其值为 NULL 。
有人可以帮我吗?
谢谢!

此多个查询一个接一个地执行,因此LAST_NSERT_ID()适用于任何情况。
您可以结合使用这两种技术来达到所需的目的:
connection()->begin_transaction(MYSQLI_TRANS_START_READ_ONLY);
connection()->query("START TRANSACTION;");
connection()->multi_query("INSERT INTO songs (title, disco, deleted) VALUES ('".$titol."', '".$codi."', '0');SET @last_id = LAST_INSERT_ID();INSERT INTO lyrics (`lyricsOri`, `lyricsTra`, `song`, `deleted`) VALUES ('".$lyricsO."', '".$lyricsT."', @last_id, 0);");
connection()->query("COMMIT;");
connection()->commit();
connection()->close();
现在,在相同的查询执行流中声明并使用了var,以便可以正常工作。
干杯!
