Cross Database Insert on rows

Is there a standard way to insert rows into a table and get the last inserted value for the identity column back ?
e.g. Oracle does'nt support IDENTITY or AUTONUMBER on insert as a sequence is desired. This creates a huge problem for writing cross database insert code.
Most of the times the last value inserted for the identity column has to be returned so it can be used in a database transaction.
Say User wants to insert data into an User table which has the following columns...
user_id int (PK) Auto generated number
firstname VARCHAR(20)
lastname VARCHAR(20)
In Sybase or SQL Server The user would just call
insert into User (firstname,lastname) values ('John', 'Doe') and then call select @@identity to get the last value of the PK inserted.
However in Oracle the insert method first needs to know the name of the sequence from where the value of the PK needs to be obtained. Then it has to use that value to insert row in the table.
If the sequence is Seq_User
select Seq_User.nextval from dual and then
insert into User (user_id,firstname,lastname) values (last_value, 'John', 'Doe')
Now if a user has written code using JDBC for Sybase and the Database is migrated to Oracle, He has to go changing all his inserts!!!
Is there a way to write cross database code so that user does not have to worry about changing his code for all the inserts?
Any help is greatly appreciated.
Thanks,

This has been discussed here already.
As far as I know there is no standard way.
Maybe you can make an own "standard" solution by doing your logic in a stored procedure which returns the new ID value.
So you can move all DBMS specific stuff into the stored procedure.
Of course there's a need of adapting this to each target DBMS.
Can you reduce the number of needed SPs by making them more generic?
Very similiar solution - if you like it more - would be to make generic methods, in a base class or interface and overwritten/reimplemented for each target DBMS.
There could be a good use of inheritance and polymorphism in this task which SPs don't provide (except for those DBMSses who allow Java-coded SPs, but that would be platform dependant again).

Inserting Multiple Rows into Database Table using JDBC Adapter - Efficiency

I need to insert multiple rows into a database table using the JDBC adapter (receiver).
I understand the traditional way of repeating the statement multiple times, each having its <access> element. However, I am just wondering whether this might be performance-inefficient, as it might insert records one by one.
Is there a way to ensure that the records are inserted into the table as a block, rather than record-by-record?

Hi Bhavesh/Kanwaljit,
If we have multiple ACCESS tags then what happens is that the connection to the database is made only once. But the data is inserted row by row.
Why i am saying this?
If we add the following in JDBC Adapter..logSQLStatement = true. Then incase of multiple inserts we can see that there are multiple
Insert into tablename(EMP_NAME,EMP_ID) VALUES('J','1000')
Insert into tablename(EMP_NAME,EMP_ID) VALUES('J','2000')
Doesnt this mean that rows are inserted one by one?
Correct me if i am wrong.
This does not mean that the transaction is not guaranted. Either all the rows will be inserted or rolled back.

Sumit

HI,
I have used below code for getting details from databse. Now i have to insert a row in the database.
Kindly let me know how can i use below code for inserting a row in the database. or should i make any change in its viewObject's Query.
If there is any another way of inserting data in database through method binding please let me knoe that.

Kindly help me to shortout this.

How to eliminate inserting Duplicate rows into database using JDBC Adapter

File->Xi->JDBC
In above Scenario if the file has two rows their values are identical, then how can we eliminated inserting Duplicate rows into database using JDBC Adapter

Database is a consumer of a SERVICE (SOA!!!!!!).
Database plays a business system role here!!!!
Mapping is part of an ESB service
Adaptor is a technology adapted to ESB framework to support specific protocol.
ESB accomplish ESB duties such as transformation, translation, routing. Routing use a protocol accepted by the consumer. In a JDBC consumer it is JDBC protocol and hence it a JDBC adaptor.
There is clear separation on responsibilities among business system and ESB. ESB do not participate in business decision or try to get into business system data layer.
So who ever are asking people to check duplicate check as part of mapping (an ESB service) may not understand integration practice.
Please use an adaptor module which will execute the duplicate check with business system in a plug and play approach and separate that from ESB service so that people can build integration using AGILE approach.
Thanks

Database trigger to insert duplicated rows on audit table

Hi
It is possible to insert duplicate rows (at the moment database generate PK violation constraint for one specific table) within an audit table ?
Certain code like this is not working, always the whole transaction makes a rollback and audit table will be empty:
CREATE OR REPLACE TRIGGER USER.audit_TABLE_TRG
before INSERT ON USER.TABLE
REFERENCING NEW AS NEW OLD AS OLD
FOR EACH ROW
BEGIN
declare
V_conteo number(1) := 0;
duplicate_record EXCEPTION;
begin
select count(*)
into V_conteo
from USER.TABLE
where <PK conditions>
if V_conteo > 0 then
begin
INSERT INTO USER.AUDIT_TABLE
(<>)
VALUES
(<>);
raise duplicate_record;
exception
when duplicate_record then
INSERT INTO USER.AUDIT_TABLE
(<>)
VALUES
(<>);
raise_application_error(-20019,'Duplicated column1/column2:'||:NEW.column1||'/'||:NEW.column2);
when others then
dbms_output.put_line('Error ...'||sqlerrm);
end;
end if;
end;
END;
/

>
Exactly this is my problem , one only transaction (insert into audit table and try to insert into target table), the reason of this post is to know whether exists another way to insert all the intent duplicate records on target table into one audit table, you right ,maybe I can add one date column and modify the PK on audit table but my main problem still happens.
>
Can I ask you why you want to go trigger route for this if your intention is only to capture the duplicate records? Assuming that you are on at least on 10gR2, you can look at DML error table. If you go this route, there is no need for additional overhead of trigger, code failures, etc.
Oracle can automatically store the failed records in an error table which you could later on investigate and fix it or ignore it.
Simple example:
SQL> create table emp (empno number primary key, ename varchar2(10), sal number);
Table created.
SQL> insert into emp values(1010, 'Venkat', 100);
1 row created.
SQL> commit;
Commit complete.
Create error table to log the failed records
BEGIN
DBMS_ERRLOG.create_error_log (dml_table_name => 'emp');
END;
Now let's insert a duplicate record
SQL> insert into emp values(1010, 'John', 200) ;
insert into emp values(1010, 'John', 200)
ERROR at line 1:
ORA-00001: unique constraint (VENKATB.SYS_C002813299) violated
Now use the log table to capture
SQL> insert into emp values(1010, 'John', 200) LOG ERRORS INTO err$_emp ('INSERT') REJECT LIMIT UNLIMITED;
0 rows created.
Now check the error log table and do whatever you want
SQL> r
1* select ORA_ERR_MESG$, empno, ename, sal from err$_EMP
ORA_ERR_MESG$
EMPNO
ENAME
SAL
ORA-00001: unique constraint (VENKATB.SYS_C00
2813467) violated
1010
John
200
1 row selected.This will also capture when you do
INSERT INTO EMP SELECT * FROM EMP_STAGE LOG ERRORS INTO err$_emp ('INSERT') REJECT LIMIT UNLIMITED;
You can capture the whole record into the log table. All columns.

Insert multiple rows of records into the database

The codes below allow me to insert a row of record into the database. How would I changed these to insert multiple rows at once? Please help!
String sql = "INSERT INTO EMPLOYEES" +
"(First_Name, Last_Name, Title, Phone) " +
" VALUES " +
PreparedStatement statement = conn.prepareStatement(sql);
statement.setObject (1, First_Name);
statement.setObject (2, Last_Name);
statement.setObject (3, Title);
statement.setObject (4, Phone);
boolean returnValue = statement.execute();

Hi mystiqueX,
As wmolosho has suggested in his answer to this very same question that you also posted to the JavaServer Pages forum, you can create a batch of inserts and perform them using the "executeBatch()" method. I will use Craig's sample code to demonstrate:
(Note that this code is untested!)
conn.setAutoCommit(false);
PreparedStatement statement = conn.prepareStatement(sql);
// assume you have an array of objects here
for (int i = 0; i < data.length; i++) {
statement.setString(1, data.getFirstName());
statement.setString(2, data.getLastName());
statement.setString(3, data.getTitle());
statement.setString(4, data.getPhone());
statement.addBatch();
statement.executeBatch();
conn.commit();If you are not familiar with it, allow me to suggest looking at the Making Batch Updates lesson on the Java Tutorial.
Hope it helps.
Good Luck,
Avi.

Is this the fastest way to insert 100k rows into a database?

I'm looking to insert ~100k rows into a database as fast as possible. I'm connected to the database through a small LAN with static IP adresses. The target database is running my SQL. Here's the fastest I've gotten the code so far. Task manager shows that it's only sending like 2.5mbps. If I take the size of the 2D array (64MB) and divide by the time it takes to transfer it currently, I calculate ~160kbps. Is that the best I can hope for with the NI DB Toolkit?
CLD (2014)

Hi,
Use DB Tool Insert Data VI to insert the data in the database.
You can insert complete row data at a time. No need to insert single-single element in database this will reduce your code performance.

Can not insert a row to a table from Oracle DBA Studio

Hi,
I try to use the Oracle DBA Studio to create a table and put some test data in it. Here is what I found:
I start Oracle DBA Studio on the client machine by connecting to an Oracle server 8i (8.1.7). I create a simple table called Test with two columns: one is USER, VARCHAR2, 10; and the other is USER2, CHAR, 2. After that, I right click on the table name and select "Table Data Editor" from the popup menu. The table editor window shows up. I type in the value 'AA' and 'BB' in the grid of two columns. Then I click the Apply button. An error message box popped up:
ORA-00928 missing SELECT keyword.
I click Show SQL button. The SQL statement is as following:
INSERT INTO "TASYS"."TEST" (USER ,USER2 ) VALUES ('AA' ,'BB').
I copy the statement to SQL Plus and run it. The same error is generated. But if I remove (USER, USER2) from the statement, it inserts a row without complaint. In other word, the database will not allow to insert if individual columns are list. I realize something must wrong with the new server and client installed and could not figure out what happening. Hope someone can help.
Thanks.

I am not sure, but could it be that USER is a keyword or predefine word. Check Oracle'slist of predefine/keyword

ODI - SCD Type 2 - Insert new row error

Hi All,
For Dimension I have a surrogate key, a natural key, and a column with "overwrite on change", start_date, end_date, current_record_ind. When I run the interface with the default SCD Type 2 for SQl server, this runs fine. But when I change that one column from "overwrite on change" to "insert new row", it fails on the update step. What should I be looking for anf fixing.
Thanks for your time and help.

DB: SQL Server 2008.
IKM = IKM MSSQL Slowly Changing Dimension
Error Message: ODI-1228 - Incorrect syntax near the keyword from.
Code: update T
set
from database.dbo.Dim_type as T,
database.dbo.I$_Dim_type as S
where T.Cd = S.Cd
and T.Current_rec_ind = 1
and IND_UPDATE = 'U'
To overcome the issue, I have commented the update code in the Knowledge module and the insert works, but for this one it is ok, but I have requirements where one column needs to be overwritten and other column changes will require to add a new record. How to handle both?
Thanks for your time.

How to identify date & time of insertion of rows in a table

Hi,
Is it possible to identify the date & time of insertion of rows in a table?
for example:
Table name: emp
I have rows like this
emp_code name dept
pr01 ram edp
ac05 gowri civil
pr02 sam pro
i want to know the date and time of the insertion this( ac05 gowri civil).
Could you please help me.....
Thanks in advance....

psram wrote:
sorry for the confusion. I dont want to store date and time. I said that for example only.
I have table which consists of thousands of rows. I want to know the insertion date & time of a particular row.
Is it possible?So, if I have a table that stores a load of employee numbers, do you think I could get the database to tell me their names?
If you don't store the information, you can't query the information.
Ok, there are some dribbs and drabbs of information available from the back end of the database via the SCN's, Archive Logs etc., but those sort of things disappear or get overwritten as time goes by. The only way to know the information it to ensure you store it in the first place.
So, in answer to your question, No, there isn't a true and reliable way to get the data/time that rows were inserted into the table, unless you have chosen to store it alongside the data.

Please anyone help me out, on how to get this concept started.

Hello,
I have a way to do this, but it would take some hand coding on your part. If you feel comfortable hand writing php code and doing manual database calls, specificaly database INSERT calls you should be fine.
Create a custom form using the ADDT Custom Form Wizard that has all the rows and fields you need. This may take a bit if you are adding the ability for up to 20 rows, as per your diagram of the form area. The nice thing about using ADDT to create the form is that you can setup the form validation at the same time. Leave the last step in the Custom Form Wizard blank. You can add a custom database call here, but I would leave it blank.
Next, under ADDT's Forms Server Behaviors, select Custom Trigger. At the Basic tab, you enter your custom php code that will be executed. Here you are going to want to put your code that will check if a value has been entered in the form and then do a database INSERT operation on the Stock_table with that row. The advanced tab lets you set the order of operations and the name of the Custom Trigger. By default, it is set to AFTER. This means that the Custom Trigger will get executed AFTER the form data is processed by the Custom Form Transaction.
I usually just enter TEST into the "Basic" tab of the Custom Trigger. Then set my order of operations in the "Advanced" tab and close the Custom Trigger. Then I go to the code view for that page in Dreamweaver and find the Custom Trigger function and edit the code manually. It's much easier this way because the Custom Trigger wizard does not show you formatting on the code, and you don't have to keep opening the Wizard to edit and test your code.
Your going to have to have the Custom Trigger fuction do a test on the submitted form data. If data is present, then INSERT into database. Here's a basic example of what you need to do:
In your code view, the Custom Trigger will look something like this:
function Trigger_Custom(&$tNG) {
if($tNG->getColumnValue("Item_1")) {
$item1 = $tNG->getColumnValue("Item_1");
$textbox1_1 = $tNG->getColumnValue("Textbox_1");
$textbox1_2 = $tNG->getColumnValue("Textbox_2");
$textbox1_3 = $tNG->getColumnValue("Textbox_3");
$date1 = $tNG->getColumnValue("Textbox_3");
$queryAdd = "INSERT INTO Stock_table
(item, Qty_In, Qty_Out, Balance, Date) VALUES($item1, $textbox1_1, $textbox1_2, $textbox1_3, $date1)"
$result = mysql_query($queryAdd) or die(mysql_error());
This code checks to see if the form input field named Item_1 is set. If so, then get the rest of the values for the first item and insert them into the database. You would need to do this for each row in your form. So the if you let the customer add 20 rows, you would need to check 20 times to see if the data is there or write the code so that it stops once it encounters an empty Item field. To exit a Custom Trigger, you can return NULL; and it will jump out of the function. You can also throw custom error message out of triggers, but this post is already way to long to get into that.
$tNG->getColumnValue("Item_1") is used to retrieve the value that was set by the form input field named Item_1. This field is named by the Custom Form Wizard when you create your form. You can see what all the input filed names are by looking in the code view for something like:
// Add columns
$customTransaction->addColumn("Item_1", "STRING_TYPE", "POST", "Item_1");
There will be one for each field you created with the Custom Form Wizard.
Unfortunately, I don't have an easy way to do what you need. Maybe there is a way, but since none of the experts have responded, I thought I would point you in a direction. You should read all you can about Custom Triggers in the ADDT documentation/help pdf to give you more detailed information about how Custom Triggers work.
Hope this helps.

Error while Insert new Row in Entity Base View Object

Hi,
can someone tell me the reason of following problem? :
There is a Entity Base View object, which is Binded as ADF Table in a JSFX Page.
I took the standard operations from the Control Panel: CreateInsert, Commit and Rollback.
Places them a ADF Buttons.
Whenever i am trying to insert a Row, after commit i am getting the ORA Error: ORA-01410: invalid ROWID.
By the way: The Entity Object is using the RowID as Primary Key.
When i press commit a second time, the the Row is inserted in the Database.
Any Idea, how to workarround this ORA Error?
Thank You!

n by default if you had no pkconstrainst in db,
in jdev default rowid as prim key.
as john said make the key as proper.
and do it.
if you have db constrainst in db.
it can be achived by dbconstrainstname with ora.
what am saying dbconstranist name will map it ora.

Is this with the Travel database or another database?
If it's another database then make sure your columns
allow nulls. To check this in the Server Navigator, expand
your DataSource down to the column.
Select the column and view the Is Nullable property
in the Property Sheet

OBIEE 11g caching question - cross database joins

Hi, I'm seeing something strange (a.k.a. not wanted) in OBIEE (11g, not sure that version matters).
I have a simple data mart that contains spend information. The supplier dimension contains keys that can be used to join it to detailed supplier information and supplier address information in our ERP system (that sits in a different database / on a different box). In the OBIEE physical layer I've created a cross database join between the supplier dimension table and the ERP tables that contain the address info.
Here's the odd behavior I'm seeing. If I write an answers request to select the supplier, some address info, and total spend for fiscal year 2010, I'm seeing OBIEE fire off two queries (this I expect):
A) Select supplier, address key, and total spend for fiscal year = 2010 against the spend mart
B) select address_key and associated address info against the ERP system (no limit on this query, it pulls back all rows from the address table)
OBIEE then does an internal join itself and serves up the results, everything is correct. But here's what's "wrong" - if I then run the exact same answers request, but change the fiscal year to 2009, I again see OBIEE firing off the two queries. What I expected and/or want to see is that, since the entire result set from query #B doesn't change at all, that it wouldn't have to rerun this query. However, it seems to be.
Is there any way to get #B to cache so that, for any subsequent query that contains supplier address info, OBIEE can pull it from cache instead of rerunning the query (which is pretty slow)? I really thought it would do that, but it doesn't seem to be.
Thanks!
Scott

Hi,
Could you give a bit more of context for this case? The table in SQL server; Is it a dimension and the one in Oracle DB is a fact? I am guessing, you have set up the driving table here. Have you given a try taking it off, and let BI Server do the filter in memory?
