MySQL过程将空结果返回给PHP

I have an issue where I wrote a stored procedure that inserts data into a bunch of tables and then finally returns and id by selecting it. when I execute the stored procedure in PHPMyAdmin, the data is inserted and the ID returned.

我有一个问题,我写了一个存储过程,将数据插入一堆表,然后通过选择它返回和id。当我在PHPMyAdmin中执行存储过程时,将插入数据并返回ID。

When executing the procedure from PHP using MySQLi, the data is inserted into the tables however when I check the results to retrieve the new id, the result seems to be blank. Any help here would be appreciated. I am not sure if the procedure returns empty results before it returns the result containing the row with the new ID. The Blank lines in the Execution results in phpMyAdmin is a bit of a bother to me?

当使用MySQLi从PHP执行过程时,数据被插入到表中,但是当我检查结果以检索新id时,结果似乎是空白的。任何帮助在这里将不胜感激。我不确定该过程在返回包含具有新ID的行的结果之前是否返回空结果。 phpMyAdmin执行结果中的空行对我来说有点麻烦?

instead of SET eventid = LAST_INSERT_ID(); write

而不是SET eventid = LAST_INSERT_ID();写

select LAST_INSERT_ID() into eventid;
