问题

This question already has an answer here:

MySQL and the chance of the wrong id being returned by LAST_INSERT_ID() (1 answer)

Closed 6 years ago.

I've a database with hundreds of records which inserted in each seconds, I have the below insert query and I want to know the insert id of this query:

   $currQuery = $pdo->prepare("INSERT INTO some_table (...... )");
   $currQuery->execute("....");
   $queryInsertId = $pdo->lastInsertId();

I just want to know that is it safe to use lastInsertId() while I having hundreds of new records in every seconds? any ideas?

回答1:

Yes it is safe. It returns the last insert id for the connection.
