I have a table which has got a column with AUTO INCREMENT
. I have to retrieve the value of this column when inserting a new row (i need the value of the new row). I've read a lot about it and found different solutions, one is to use SELECT LAST_INSERT_ID()
. I've heard many different things about this. Can I or can i not use this? I am worried that another connection may insert a new row before I am able to call SELECT LAST_INSERT_ID()
, and therefore get the wrong ID.
To sum up, is it safe to use SELECT LAST_INSERT_ID()
? If not, how can I retrieve the last inserted id in a safe way?
I dont think that you need to worry about the case you are mentioning here.
From Mysql documentation:
The ID that was generated is maintained in the server on a per-connection basis. This means that the value returned by the function to a given client is the first AUTO_INCREMENT
value generated for most recent statement affecting an AUTO_INCREMENT
column by that client. This value cannot be affected by other clients, even if they generate AUTO_INCREMENT
values of their own. This behavior ensures that each client can retrieve its own ID without concern for the activity of other clients, and without the need for locks or transactions.

Although, i would love to read from others if they have different opinion.
