How to call mysql_insert_id
A long time ago, I posted this query: If I use the auto-increment feature for a couple of normallized relations, how do I insert into them? Specifically, when I insert into a relation with the autoincrement feature on the primary key, how do I get the value of the index on the newly created row so I can use that the value of a foreign key in another relation? That's database specific, and you haven't specified a database. * In MySQL - mysql_insert_id() How do I call this function? I was hoping I could use SQL such as SELECT mysql_insert_id() FROM XYZ but I discovered that does not work. I'm using a mixture of java and perl. I see in my old documentation that PHP programmers can call such a function. Thanks, Siegfried

Thanks, JP. And will this work for multi-threaded, multi-user applications?

Siegfried Yes: The last ID that was generated is maintained in the server on a per-connection basis. This means the value the function returns to a given client is the most recent AUTO_INCREMENT value generated by that client. The value cannot be affected by other clients, even if they generate AUTO_INCREMENT values of their own. This behavior ensures that you can retrieve your own ID without concern for the activity of other clients, and without the need for locks or transactions. See http://dev.mysql.com/doc/mysql/en/information-functions.html and look for LAST_INSERT_ID().

How To call mysql_insert_id
Hi, I am a newbie in MySQL. I use an auto_increment to insert to one of the column. How do I get the value inserted? The documentation seems to suggest using mysql_insert_id() function. But when I tried to call it using Select mysql_insert_id() or Select mysql_insert_id() from TABLE_NAME gives me error. I tried to find something in the doc, but it does not really help. Please help. Thanks in advance. Reuben D.

RE: How To call mysql_insert_id
You were close to it. But he way to get the last inserted item on AUTO_INCREMENT field is for example: id = mysql_insert_id(mysql); printf(The last insert is: %d\n, id); And mysql is what was return to you when you open your connection to the database.

The documentation seems to suggest using mysql_insert_id() function. But when I tried to call it using Select mysql_insert_id() or Select mysql_insert_id() from TABLE_NAME mysql_insert_id() is the C API function for obtaining that value. Use LAST_INSERT_ID() instead: SELECT LAST_INSERT_ID() You don't want SELECT LAST_INSERT_ID() from TABLE_NAME, probably. That will give you the insert-id value once for each row in TABLE_NAME. gives me error.
