Last_insert_id()

Hi all,
I am using container manager entity beans.
I have inserted a new row into my mysql database, primary id is of auto_increment and I am trying to retrieve the new id created.
I have used em.createQuery("select last_insert_id()") , and I get a bunch of errors.
Would anyone be able to help me or help me get on the right path.
Regards,
Deniz

MySQL Transaction last_insert_id

Can anyone tell me how to get the last inserted id when in transaction ?
I have to do inserts in several tables.
Problem is when inserting into one table my auto_increment id of the table should be used as a foreign key in the next table and so on.
I think when in transaction I cannot query for the last_insert_id with my existing connection, because it is not yet committed.
Is there a (standard) way to solve this problem ?

It depends what you mean by "standard". Standard to MySQL, you could use this:
SELECT LAST_INSERT_ID();
Some vendors provide driver-specific extensions to allow retrieval of such a value.
If you want a more portable solution then you could create a stored procedure to carry out the insert and have it return the ID as an out value.
There are other techniques, but I don't think there's a "standard" way to retrieve this value on insert, because this isn't a "standard" SQL feature in the first place.
Oh, and as far as I know most users couldn't care less about the duke dollars thing - they're not actually useful in any way.
Patience is a virtue.

How can you update to the same row when........

Ok so now I have Session variables working correctly and come
to find out that my host creates a new DB connection for each page
displayed. So the Last_Insert_ID() will not work because of the new
connection each time. What are my options for updating a row after
an insert. I am using MySQL 4.1 and CF 7.
Thanks
Shane

Hi Sankalan, thanks for your input. I am trying now to get
the following code to work on the Insert page and keep getting this
error "Element AD_ID is undefined in LASTINSERTID"
Not sure what is wrong but I have tried many different
changes and it still will not clear the error.
Any help would be great.
Shane
<cfparam name="SESSION.Last_Insert_id" default="1">
<cflock scope="Session" timeout="30" type="Exclusive">
<cfset SESSION.LAST_INSERT_ID=#LastInsertid.AD_ID#>
</cflock>
<cfquery name="LastInsertID" datasource="saa">
SELECT LAST_INSERT_ID() AS AD_ID;
</cfquery>
<cfoutput>#LastInsertid.AD_ID#</cfoutput>

Anyone know how to insert to multiple tables on Dreamweaver?

Hey everyone,
I'm a bit of a newbie at PHP and am trying to create my first "dynamic" site. I have a registration table with fields idNo (primary key & auto-increment), username, password, email. I also have another table called profile with fields idNo, location, musicalInfluences, aboutMe etc. All of these fields except idNo have the default value of "update." What I want to be able to do is add a second insert statement to the user registration behaviour so that I can have the idNo number added to the profile tables as well as the registration table. That way the registration and profile are linked by idNo and I can create a record-set do automatically populate the profile table on my profile page when the user logs in. All of the different profile traits would say "update" and I can then use an update server behaviour for the user to update there profile.
I might be approaching this the wrong way so I'm open to suggestions on how to create a user login and linked profile page. One thing I could not work out was how, when the user clicks login with the correct credentials, I was supposed to separate a first time user, directed to the create profile page, from a user who has already created a profile page and just wants to see it. The only way I could think of was by using the default method explained before and then having an update page. Sorry if that was a bit of a waffle. Here is my code. Any help would be much appreciated!!
This is the script that I have included on my registration page. I just extracted the php and used an include to keep the html page tidy.

you can use a trigger in mysql. this trigger is for new records in your registration table. you can use mysql's last_insert_id() to get the last record inserted. just search for mysql triggers to get more info. note that this is not php code, it is mysql.

I dont know what table names and fields you have but
say you have a table called XYZ which has a primary
key field called keyID.
So in order to get the last row inserted, you could
do something like
Select *
from XYZ
where keyID = (Select MAX(keyID) from XYZ);
Good Luckwhat gubloo said is correct ...But this is all in MS SQL Server I don't know the syntax and key words in MYSQL
This works fine if the emp_id is incremental and of type integer
Query:
select      *
from      employee e, (select max(emp_id) as emp_id from employee) z
where      e.emp_id = z.emp_id
or
select top 1 * from employee order by emp_id descUday

Algorithm help

i have an issue trying to figure out the proper way to insert records into a database table. i apologize if this is more a database question than a java question but i didn't know where else to turn.
my issue is trying to understand the best way to deal with autoincremented primary key fields used as row ids when you would need to use them for other detail and line tables. lets say it is a user table and i insert a user into it and its id is created off the autoincrementor...i proceed to want to add records to other tables and link them to this user i need to know what the id incremented to?
so is the following algie correct:
synchronize {
insert record;
get max(id) from table;
thx, graeme.

hmm, yes good point. i just read up on the mysql
docs some functions that are connection specific so
that can be sure the value retrieved won't be
affected by other connections:If you set the isolation level properly and do things in a transaction you'll be fine.
>
i.e. last_insert_id(). thanks for the reply i'm
going to look into these sequencers of oracle as well.Bad idea. This is MySQL-specific. The instance you use this function, your code isn't portable anymore. At least hide that implementation behind an interface if you must.
It's SEQUENCE, not sequencers.

JClient: after INSERT and COMMIT does not show the primary textfield value

1. In my JClient master-detail form: When I insert a new record, enter data, and commit the changes... the master-panel's primarykey textfield is BLANK, when it should show the new auto-incremented number from the MySQL database. I have to close and open the form again to refresh that field again.
2. In order to properly save new records in the detail-panel, I have to insert and save the above master-panel first. Is this the way JCLient handle master-detail forms?
Thanks.

Hi. Thanks for sharing your advice.
Re my problem,
if we have to refresh data by requery,i suggest you should use the way below:
private JUNavigationBar navBar = new JUNavigationBar(true,false,true,false,true);
navBar.setModel(JUNavigationBar.createPanelBinding(panelBinding, navBar));
// after insert ,call this method
navBar.doAction(navBar.BUTTON_EXECUTE);Tried this out but my textfield still won't get refreshed. Here is the code I came up with:
    private JUNavigationBar navBar = new JUNavigationBar() {
            public void doAction(int button) {
                if (button == JUNavigationBar.BUTTON_INSERT) {
                    super.doAction(button);
                    navBar.doAction(navBar.BUTTON_EXECUTE);
                    return;
                super.doAction(button);
        };Re your problem,
I am developing application with JDev + MySQL,encounted another problem,
how can i get the primary key supported by auto_increment column after insert?
i constructed a vo whose sql statement is
select last_insert_id() as last_id to get the value of auto_increment column.
i found it can't get the right value unless commit the transaction.
Would u please tell me your way?Based on what I experienced, we dont have to do the SELECT statement above. MySQL does auto-increment the primarykey but the JClient form just cant show it immediately, unless we close and re-open the form.
What did I do to refresh the primarykey during insert? Please note that I got this solution accidentally coz I'm still a newbie in Java.
A user want to add a record:
1. He presses the Insert button.
2. He enters data into a component (ex. textfield)
3. The component's action-performed event is fired, and the following code is run:
        DCJboDataControl dc = (DCJboDataControl)panelBinding.getDataControl();
        ApplicationModule am = dc.getApplicationModule();
        Transaction tr = am.getTransaction();
        dc.commitTransaction();
        ViewObject vo = am.findViewObject("TblaccountsView1");
        vo.executeQuery();
        vo.last();It simply commits the transaction, goes to last (new) transaction, and lets the user continue his data encoding.
Hope it helps and I hope theres an even better way to do this.

Database toolkit - stored procedure doesn't work in labview

Hello,
I have written simple procedure that works good when I run it from workbench but doesn't work from labview. I want to insert some data and get primary key of inserted id:
CREATE DEFINER=`root`@`localhost` PROCEDURE `new_procedure`(
IN emp_id_val int,
IN project_id_val int,
IN work_mode_val int)
BEGIN
insert into work_managment.sessions (emp_id,project_id,work_mode)
values (11,1,1);
SELECT LAST_INSERT_ID();
END
and why that doesn't work when I call it from labview?
when i replace last inserted id with:
select max(session_id) as session from work_managment.sessions;
it works good in labview
What could be the problem??

It could be that there is something screwy with LV, but given that it uses standard interfaces for comm with the DBMS, I would not expect that. A much more realistic possibility is that the toolkit is mucking things up. (A fairly common occurrence.)
Try bypassing the toolbox -- which you don't really need anyway -- an talk directly to the ActiveX or .net interface.
Also, what DBMS? What drivers are you using?

How can I use a mySQL database schema with numeric auto increment primary key instead of GUID?

Hello!
I'm using the TestStand "MySQL Insert (NI)" database schema with GUID as primary key. So everything works fine.
But I prever using numeric values as primary key, because the database is in conjunction with another database which uses numeric values as primary key.
Is this possible?
Has anyone an idea how I can modify the "Generic Recordset (NI)" for use with MySQL?
Thanks!
Configuration:
Microsoft Windows XP
TestStand 3.1
MySQL 4.1.12a
MySQL ODBC 3.51 Driver
Brosig

Adam -
The TestStand Database Logging feature does not allow you to run a separate SQL command after executing the command for a statement(table), so I do not think that you can use an auto incrementing column for the tables. There is just no way to get it back in a generic way. One option that I tried is something similar to the Oracle schema where you call a store procedure to return a sequence ID for each record that you want to add.
So you would have to create the following sequence table in MySQL:
CREATE TABLE sequence (id INT NOT NULL);
INSERT INTO sequence VALUES (0);
Then create a stored procedure as shown below that will increment the sequence value and return it in a recordset:
CREATE PROCEDURE `getseqid`()
BEGIN
        UPDATE sequence SET id=LAST_INSERT_ID(id+1);
        SELECT LAST_INSERT_ID();
END
Then update the MySQL tables to use INT primary and foreign key values, so the TestStand MySQL SQL file to create all tables would have text like this:
CREATE TABLE UUT_RESULT
ID    INT PRIMARY KEY,
~
CREATE TABLE STEP_RESULT
ID    INT PRIMARY KEY,
UUT_RESULT   INT NOT NULL,
~
Then update the schema primary and foreign key columns in the TestStand Database Options dialog box to be INT to match the table. For the primary key columns, you will have to set the Primary Key Type to "Get Value from Recordset" and set the Primary Key Command Text to "call getseqid()". This will call the stored procedure to determine the next value to use as the ID value.
Hope this helps...

Best Practice: Combine prepared statements with ;

Hi,
I would like to know what the best prctice is for combining prepared statements to give the query below
INSERT INTO my_table (value) VALUES (?); SELECT LAST_INSERT_ID()The reason for this is that i have written a simple DB wrapper to handle my database connections and queries based on a property file containing sql strings. I would prefer not to change this wrapper code, but be able to specify combined queries in the sql string if possible.
Thanks in advance

Have you thought about using Batch statements ?

Javax.servlet.ServletException: Before start of result set

I have a page where i want to put items that have been entered into a bean and put them into my SQL database. Firs of all i want to insert some value into my question table and then I use the SELECT LAST_INSERT_ID() function in mySQL to get the last incremented ID from the first statement. As you can see I then want to use this ID and insert it into the other statements to relate the tables but I get an exception which is shown below. The frist insert staemet works fine when the rest is commented out but when i try it with the other 2 insert statements it throws this back at me.

further to Limo2kz's problem, LAST_INSERT_ID() will return 0 if the last INSERT statement actually has inserted 0 records. this could happen if the previous INSERT attempt has failed.
as far as i can remember, you should find out if the account or user that you are currently using to connect to MySQL database is allowed to do more SQL executions and create more SQL connections at certain given time (i.e., 10 executions in 1 hour, 10 connections in 1 hour). otherwise, you would have subsequent SQL exceptions because the database server won't allow you to execute them, thus giving you a null ResultSet.

Once again: Does MySQL allow multiple querys in one database transaction???

Hello to ALL!!!
The problem is:
I'm trying to make simple query (database: "myDB" (engine:
myisam/innodb - doesn't mater) with one table: "Info" with two
columns: "Id" (autoinc), "info_c" (varchar):
<cfif structkeyexists (form, "name")>
<cfquery datasource="myDB" name="qDB" >
INSERT into Info (info_c)
VALUES ('#form.name#');
SELECT @@identity AS Id
</cfquery>
</cfif>
<cfform>
<cfinput type="text" name="name">
<cfinput type="submit" name="submit">
</cfform>
BUT after "Submit" I get:
Error Executing Database Query.
You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to
use near '; select @@identity as Id' at line 2
Please, tell me WHY???
I have:
MySQL
Server information:
MySQL version: MySQL 5.1.25-rc-community via TCP/IP
Clent Information:

Great THANKS for your answers!!!

> SELECT @@identity AS Id
AFAIK, MySQL uses LAST_INSERT_ID(). @@IDENTITY is MS SQL
specific. Though SCOPE_IDENITY() is recommended over @@IDENTITY.
What version of CF are you using? ColdFusion supports the
"result" attribute, which will return the ID value for simple
inserts. See the documentation for details
http://livedocs.adobe.com/coldfusion/8/Tags_p-q_17.html
> Do JDBC drivers for MySQL prohibit the use of multiple
queries
> in a single database transaction???
For security purposes this is disabled by default. To enable
it you must modify your datasource url

Possible thread issue?

I'v now come across a code problem that I simply cannot understand what is happending here.
The code is part of a cfc module that is behind a web-service.
The problem here is the transID.
When you start putting a bit of load on this code, the transID gets mangled/confused/....
When looking at the first cflog here, the trans id is the correct value is an thedatabase table.
However, after the values are assigned to stTrans, the trans id is different! It is that of another tx that happend later on...
Nowere is the transID updated in the code between the two cflog's. The value in the cflog is correct, as it is this value that I receive on the other side of the WebService module....
Here is the logfile output

I found a problem when I did code optimizationon the other side of the webservice. First thought it was the web service, but trace it right down to this bit of code on the one server.
This is happening on my Mac's VM's running CentOS 5.2 and Coldfusion 8 on top of that.....
