I don't think its possible to do what you want in a single statement. Since
LAST_INSERT_ID() is set to the last insert id of the connection... and the
row you are inserting doesn't exist.. well.. until you create it, it will
always either be zero or the record BEFORE your next insert, ie:

OK, I can make an UPDATE after an INSERT but then I can't use UNIQUE for
the Coloumn with the CRC32...
Before I can make an Update, the Value is 0...

last_insert_id is on a per-connection basis i.e. it gives the last id
inserted using that particular connection. Therefore you will always get
the most recent ID that you inserted, not the most recent that anyone
.
- if one user inserts and retrieves the id, but between both one other
has inserted something the id returned will be the right one?
Last_insert_id() is consistent on a per-connection basis, meaning you
don't need to use lock (hopefullly !)

This seems fine to me as I don't want to lock the tables, and the

What you're describing cannot be achieved in the general case.
Yes, I know about this. What I plan is to remove the auto_increment. I will

(id int not null auto_increment, name varchar(255))
and did an SQLQuery thru JDBC
insert into TABLE (name) values ('test');
select last_insert_id() from TABLE;
but got the Exception
java.sql.SQLException: Invalid value for getInt() - 'q'
while successive running
Yea thanks for correct this, so I'm getting the right resultSet in
console...
but still having problem thru ConnectorJ, select last_insert_id() returns
a String to me, rs.getString(1) throws no exception.
Tea
You don't select last_insert_id() from table.
This will return
, name varchar(255))
also tried
test (id int not null auto_increment, name varchar(255))
and did an SQLQuery thru JDBC
insert into TABLE (name) values ('test');
select last_insert_id() from TABLE;
but got the Exception
java.sql.SQLException: Invalid value for getInt() - 'q'
while successive
is the code segment
String insertStmt = insert into test (name) values ('hi');
String queryStmt = select last_insert_id();
try {
stmt.executeUpdate(insertStmt);
ResultSet rs = stmt.executeQuery(queryStmt);
if(rs.next())
System.out.println(last insert id
Okay, I've seen just about every question on last_insert_id(), except this
one:
I am running MySQL on Win XP and when I generate a test table (test) with an
AUTO_INCREMENT column (aid) and a second column (a) then use an insert
statement like: INSERT INTO test (a) values (1); then: SELECT

LAST_INSERT_ID is held for the database connection, not agaist the
server
So, as long as you do not do another insert using the same database
connection, LAST_INSERT_ID will be fine.
(for database connection, $dbh=DBI-connect. )
No table locking required.

Nope. That doesn't do it either!
I go:
TRUNCATE TABLE my_table
Are you using InnoDB tables? You'll have to do something akin to ALTER
TABLE my_table AUTO_INCREMENT=1 ... at least according to Paul ... :)
I'm working with MySQL 3.23.36 so, according to MySQL, Paul Dubois, New
Riders running the query:
DELETE FROM my_table_name
should reset the auto-increment value... but it doesnt'.
What SQL do I use to reset the val.
You can't believe anything that book says. The author didn't even include
http://www.mysql.com/doc/en/SET_OPTION.html
last option(s)
maybe you can do somehting with that
