Insert into multiple table view
I have a view with multiple table query and and INSTEAD OF trigger on the view that inserts into multiple tables. When I attempt to do a commit out of a ADF Creation Form, I get the following error: ORA-01779: cannot modify a column which maps to a non key-preserved table ORA-06512: at line 1.
Has anyone had success inserting into multiple tables via a view that has more than one table?
Thanks,
Lisa
Lisa,
Sounds like your instead-of trigger may not be being called and you are trying to insert directly into the view.
I did write a [url http://stegemanoracle.wordpress.com/2006/03/15/using-updatable-views-with-adf/]blog entry about using a view with instead-of triggers last year.

I know there is Composite Transaction of inserting into multiple tables in SQL.
Is there a way where we can have inserts into multiple table at once ? If yes, can anyone please provide step by step procedure to achieve this

Inserting into multiple tables on one form using UIX
We are developing an application using struts and UIX. We would like to be able to insert into three tables on one form(view). How can we accomplish this?
This is more of an ADF question, you'll need to set up view object, than just drag it from the data control palette like normal.
If it's not already set up as a view in the db (split into multiple tables), you'll need to create a view object that includes all the fields you want, based on multiple entity objects. -
Hi all,
Apologies if any of the following sounds at all silly but I am fairly new to this so here goes...
I have 3 tables that require data insertion at the same time. The first table is the customers table, I then want to take the automatically generated custid from that table and inser it into 2 other tables along with some other data
Here's what I have so far which does not work:
CREATE PROCEDURE CustomerDetails.bnc_insNewRegistration @CustId int,
@CompanyName varchar(100),
@FirstName varchar(50),
@LastName varchar(50),
@Email nvarchar(254),
@HouseStreet varchar(100),
@Town smallint,
@County tinyint,
@Postcode char(8),
@Password nvarchar(20)
AS
BEGIN
begin tran
insert into CustomerDetails.Customers
(CompanyName, FirstName, LastName, EmailAddress)
Values (@CompanyName, @FirstName, @LastName, @Email)
set @CustId = (select CustId from inserted)
insert into CustomerDetails.Address
(CustomerId, HouseNoAndStreet, Town, County, PostCode)
values (@CustId, @HouseStreet, @Town, @County, @Postcode)
insert into CustomerDetails.MembershipDetails
(CustomerId, UserName, Password)
values (@CustId, @Email, @Password)
commit tran
END
GO
If anyone could help with this I would very much appreciate it as I am currently building an online store, if there's no registration there's no customers.
So to whom ever is able to help, I thank you whole heartedly :)I hope by now it is apparent that statements like "doesn't work" are not particularly helpful. The prior posts have already identified your first problem. But there are others. First, you have declared @CustID as an argument for your
procedure - but it is obvious that you do not expect a useful value to be supplied when the procedure is executed. Perhaps it should be declared as an output argument so that the caller of the procedure can know the PK value of the newly inserted customer
- otherwise, replace it with a local variable since it serves no purpose as an input argument.
Next, you are storing email twice. Duplication of data contradicts relational theory and will only cause future problems.
Next, I get the sense that your "customer" can be a person or a company. You may find that using the same table for both is not the best approach. I hope you have constraints to prevent a company from having a first and last name (and
vice versa).
Next, your error checking is inadequate. We can only hope that you have the appropriate constraints to prevent duplicates. You should expect failures to occur, from basic data errors (duplicates, null values, inconsistent values) to system issues
(out of space). I'll leave you with Erland's discussion for more detail:
erland - error handling.
Lastly, you should reconsider the datatypes you are using for the various bits of information. Presumably town and county are foreign keys to related tables, which is why they are numeric. Be careful you don't paint yourself into a corner with
such small datatypes. One can also debate the wisdom of using a separate tables for Town and County (and perhaps the decision to limit yourself to a particular geographic area with a particular civic hierarchy). Password seems a little short to me.
And if you are going to use nvarchar for some strings, you might as well use it for everything - especially names. Also, everyone should be security conscious by now - passwords should be encrypted at the very least.
And one last comment - you really should allow 2 address lines. Yes, two separate ones and not just one much larger one. -
Insert into multiple tables; grab id from first
I apologize if this has been answered elsewhere, but I tried
searching and got no results.
I'm trying to insert the contents of one form into two
tables. After inserting some fields into one table, I want to grab
the key/id from the first table into the second table with the
other fields.
I've tried a few different things, including trying to use
SCOPE_IDENTITY(), but just kept getting lots of errors.
The current version of my code works perfectly, *except for
the fact that it doesn't insert the ID*!
Can anyone tell me what I'm doing wrong? or offer another way
of doing this?
Thanks for your help, as usual.MarianneStone wrote:

The EmployeeID is not inserted because the getMyID query
cannot find the newly inserted record. When using a UUID to
identify the new records ..
<cfquery name="qAddDeptHead" datasource="#db#"
result="result">
INSERT INTO Employee(... , EmpUUID)
VALUES ( ... , '#CreateUUID()#')
</cfquery>
You have to use that _same_ UUID to find the record, _not_
create a new one.
<cfquery name="getMyID" datasource="#db#">
SELECT EmployeeID, EmpUUID
FROM Employee
WHERE Employee.EmpUUID='#UseTheSameUUIDFromTheFirstQuery#'
</cfquery>
As an aside, you could probably do this in two queries not
three. Just drop the second SELECT query and use an INSERT
INTO/SELECT .. FROM Table statement instead. Plus you should also
consider using cfqueryparam for your query parameters. It has many
benefits.

> Can anyone ... offer another way of doing this?
There are a few options. For ColdFusion 8, you could use the
result attribute. After running the INSERT you can grab the new
EmployeeID by using #yourResult.IDENTITYCOL#
<cfquery name="qAddDeptHead" datasource="#db#"
result="yourResult">
INSERT INTO Employee ( Columns here )
VALUES (... values here ...)
</cfquery>
For earlier versions, you can either use SCOPE_IDENTITY() or
a UUID value - as you are currently doing now.
> I've tried a few different things, including trying to

If you use SCOPE_IDENTITY() turn off the rowcount, or the
query variable "qAddDeptHead" may be undefined when you try and use
it.
<cfquery name="qAddDeptHead" datasource="#db#"
result="yourResult">
SET NOCOUNT ON;
INSERT INTO Employee ( Columns here )
VALUES (... values here ...)
SELECT EmployeeID AS NewEmployeeID
SET NOCOUNT OFF;
</cfquery>
<cfquery name="qNewEmpPosition" datasource="#db#">
INSERT INTO EmployeePositions(EmployeeID, .... )
VALUES ( #qAddDeptHead.NewEmployeeID#, ....)
</cfquery> -
Hi experts,
I would like to consulate if you can recommended on how to build a logic at the entity object. We have two tables or entites A and B and whenever a new record is inserted into table or entity A, a new record will be dependently inserted in table or entity B.
Can you please advise us on how to code this.Ok, now we know that there is a relation, still we don't see what kind of relation.
Then the next question it's how do you find out off there is a 'parent'?
Again, provide more detailed information.
What I can tell you right now it's that I don't see a problem implementing this using ADFbc.

Insert into multiple tables using a page variable
Hi Guys,
I was going to trawl the PL/SQL forum for this but as I need to use a page variable I thought I would try here first.
I have 4 tables 2 live and 2 archive, company_table, company_table_arch, product, product_arch the tables are set up with a company Id as the join.
you can have multiple products to a company.
what I want to do is have an archive button on a form that will select the current record on the company table, and insert it into archive then select all records with that id in the product table and insert them into the product_arch table.
I was thinking about doing this as a couple of page proccess, sound about right?
the other option was using a package,
is it possible to use page variables in a package? If so what is the sintax
cheers
BjornOK, I have got the basis of this working I press the archive button and the records update as per the code.
I have one problem however.
The button is on a form. and if the user updates the form then presses the archive button it copies the data before the table is updated (the table is updated using a save button).
One way round this would be to jump to an "are you sure?" page
Does anyone know a better way of doing this?
cheers

Efficient Way of Inserting records into multiple tables
Hello everyone,
Im creating an employee application using struts framework. One of the functions of the application is to create new employees. This will involve using one web form. Upon submitting this form, a record will be inserted into two separate tables. Im using a JavaBean (Not given here) between the JSP page and the Java file (Which is partly given below). Now this Java file does work (i.e. it does insert a record into two seperate tables).
My question is, is there a more efficient way of doing the insert into multiple tables (in terms of performance) rather than the way I've done it as shown below? Please note, I am using database pooling and MySQL db. I thought about Batch processing but was having problems writing the code for it below.
Any help would be appreciated.

Insert into two tables, how to insert multiple slave records
Hi, I have a problem with insert into two tables wizard.
The wizard works fine and I can add my records, but I need to enter multiple slave table records.
My database:
table: paper
`id_paper` INTEGER(11) NOT NULL AUTO_INCREMENT,
`make` VARCHAR(20) COLLATE utf8_general_ci NOT NULL DEFAULT '',
`model` VARCHAR(20) COLLATE utf8_general_ci NOT NULL DEFAULT '',
`gsm` INTEGER(11) NOT NULL,
PRIMARY KEY (`id_paper`)
table: paper_data
`id_paper_data` INTEGER(11) NOT NULL AUTO_INCREMENT,
`id_paper` INTEGER(11) NOT NULL,
`value` DOUBLE(15,3) NOT NULL,
`nanometer` INTEGER(11) NOT NULL,
PRIMARY KEY (`id_paper_data`)
I need to add multiple fields "value" and "nanometer"
Current form looks like this:
Make:
Model:
Gsm:
Value:
nanometer:
I need it to look like this:
Make:
Model:
Gsm:
Value:
nanometer:
Value:
nanometer:
Value:
nanometer:
Value:
nanometer:
and so on.
The field "id_paper" in table paper_data needs to get same id for entire transaction. Also how do I set default values for each field "nanometer" on my form the must be different (370,380,390 etc)?

Hi experts,
Im using ADDT to design a page that needs to insert one record into a master ALBUMS table, along with three records into a GENRES table, all linked by the primary, auto-incremented ALBUMS. ALBUM_ID.
Ive tried many different ways of combining the Insert into Multiple Tables wizard and the insert record wizard with Link Transactions, all with no luck. Either only the album info gets inserted, or a ALBUM_ID cannot be null error from MySQL. Here is the structure of the tables
ALBUMS
ALBUM_ID, INT(11), Primary, Auto_Increment
alb_name, varchar
alb_release, YEAR
USER_ID, int
alb_image, varchar
GENRES
ALBUM_ID, int, NOT NULL
GENRE_ID, int, NOT NULL
ID, int, primary, auto-increment

Insert data into multiple tables
Hi all,
I've a requirement where i need to insert data into multiple tables using PL/SQL procedure
Procedure should have two parameters
1. Table Name (parameter1)
2. Data (parameter2)
Based on these two parameters i need to insert data into table (parameter1) using data (parameter2)
ex:
Procedure insert_data (p_table IN VARCHAR2
,p_data IN -- what should be the datatype?
IS
l_statement VARCHAR2(2000);
BEGIN
-- insert data into tables
INSERT INTO p_table
values (....);
END insert_data;Thanks in advance!!BEDE wrote:
Amen to that!
So, I believe a better approach would be the following...
Suppose you have N datafiles with the same structure, and you wish to insert into the database the data from all those files.
For that, you should have a single table, named, say incoming_file_data, which should be structured more or less like below:
create table incoming_file_data (
filename varchar2(250) not null -- name of the file inserted from
,file_time timestamp -- timestamp when the data was inserted
,... -- the columns of meaningful data contained in the lines of those files
);And you will insert the data from all those files in this table, having normally one transaction for each file processed, for otherwise, when shit happens, some file may only get to be partially inserted into the table...
Maybe one good approach would be to create dynamically an external table for the file to be loaded, and then execute dynamically insert select into the table I said, so that you will have only one insert select for one file instead of using utl_file... RTM on that.If the file structures are the same, and it's just the filename that's changing, I would have a single external table definition, and use the alter table ... location ... statement (through execute immediate) to change the filename(s) as appropriate before querying the data. Of course that's not scalable if there are multiple users intenting to use this, but generally when we talk about importing multiple files, it's a one-user/one-off/once-a-day type of scenario, so multi-user isn't a consideration. -

Inserting data into multiple tables in jdbc
I am doing on file to jdbc. Now I got a requirement to insert data into multiple tables on the receiver side. How can I do this ?
Hi,
you are going to insert data into 4 tables in a sequence one after another , I see three options.
1) Stored procedure and 2) creating 4 statement data structure (one for each table)
The third option is writing a SQL with join for the 4 tables and use action command = SQL_DML. Example as follows....
Write SQL code and place it in access tag. Pass values for the columns using key tag...
<stmt>
<Customers action="SQL_DML">
<access> UPDATE Customers SET CompanyName=u2019$NAME$u2019, Address=u2019$ADDRESS$' WHERE CustomerID='$KEYFIELD$u2019
</access>
<key>
<NAME>name</NAME>
<ADDRESS>add </ADDRESS>
<KEYFIELD>1</KEYFIELD>
</key>
</Customers>
</stmt>

Fetch data from one table and insert into two tables in desired format
I have similar to the following data in a table and it is not normalized. The groupID is being used to group two records of similar nature.
DECLARE @OldDoc TABLE (oldDocID INT, groupID INT, deptID INT)
INSERT INTO @OldDoc (oldDocID, groupID) VALUES (1, NULL, 111),(2,NULL,111),(3,1,111),(4,NULL,333),(5,1,222),(6,NULL,333),(7,2,222),(8,2,333),(9,NULL,111),(10,3,222),(11,NULL,333),(12,3,444)
I need to process the data from the above table (@OldDoc) and write into two new tables (@NewDoc and @NewDocGroup) as follows.
oldDocID should be stored as newDocID when inserting to @NewDoc table. Only records with groupID NULL and one record (first one) per group should be considered (For example, oldDocID 5 is not considered as 3 and 5 belong to the same groupID 1) for insertion.
DECLARE @NewDoc TABLE (newDocID INT)
INSERT INTO @NewDoc (newDocID) VALUES (1),(2),(3),(4),(6),(7),(9),(10),(11)
All records from @OldDoc should be considered for insertion into @NewDocGroup table. OldDocID is inserted as NewDocID and deptID is as-is. Instead of groupID, the ID of the first record in the
group should be considered as parentNewDocID (For example, 3 is considered as parentNewDocID for newDocID 5 as 3 and 5 belong to the same groupID in @OldDoc table) for the newDocID.
DECLARE @NewDocGroup (newDocID INT, parentNewDocID INT, deptID INT)
INSERT INTO @NewDocGroup (newDocID, parentNewDocID, deptID) VALUES (1,1,111),(2,2,111),(3,3,111),(4,4,333),(5,3,222),(6,6,333),(7,7,222),(8,7,333),(9,9,111),(10,10,222),(11,11,333),(12,10,444)
How do I accomplish the above using SQL ? Thanks for the help.>> I have similar to the following data in a table and it is not normalized. The group_id is being used to group two records [sic] of similar nature. <<
Rows are not records. Tables have to have a key by definition. You do not do math with identifiers, so they should not be numeric. Let's ignore that error for now. In short, you are posting garbage. If you had followed Forum Netiquette, would you have posted
this?

Just like punch cards and mag tape data processing! Being old and being new are a status, not another kind of entity. But that is how mag tapes work. And you even use the verb "fetch" from tape files. This design flaw is called attribute splitting.

Think about your punch card mindset. Why did you physically materialize that redundant New_Documents table? Let me answer that: this is how you work with punch cards! In SQL we use a VIEW:

Why not use 5 as the parent? My guess is that you are trying to form equivalence classes. See:

Can select, but cannot insert into oracle tables using php.
I am having trouble inserting data into a tables in oracle using PHP. I can insert into the tables using baninst1, but nothing else. I can't even insert using the tables' owner. Every time I try I get the ORA-00492 error of table or view does not exist. However, I can run a select statement just fine. So far, baninst1 is the only user that can actually do inserts. I've triple checked all the table grants and everything is fine. Also, I can copy/paste the exact insert statement into SQL*Plus and it works with the correct user. It doesn't have to be baninst1. I've tried everything I can think of. I've tried putting the table name in quotes, adding the schema name to the table, checking public synonyms, but everything appears to be ok. I would greatly appreciate any suggestions others may have.
I'm using PHP 5.2.3 with an oracle 9i DB.Here is the code that doesn't work. It works only with baninst1, no other username will work and all I do is change the my_username/my_password to something different. This is one example function where I try to do an insert, but it doesn't work on any of the tables I try.

Oracle 10g performance degrades while concurrent inserts into a table
Hello Team,
I am trying to insert into single table via multiple threads, Some of these threads perform reasonably well but some will take really longer time, As the time goes on performance drastically degrades (even down by 500 to 600 times). With AWR report i see that there quite huge number of buffer gets there. I am not sure how can i reduce those. If i ran on a single thread this operation is consistent.
I tried quite a few options like
1. Increasing SGA Memory
2. Moving redo logs to another disk drive.
3. Trying it on a empty table
4. Trying it on a table which has huge data (4 Million rows)
5. I have even tried partitioning the table with HASH algoritm
Note: Each thread i am pupming equal amount of data (let say 25K rows).
Can any body suggest me a clue what could be the culprit here.
Thanks in Advance

Can you please guide me how do i do that, I am not aware of how to generate explain plan for that query.Since you have the trace file already (and I don't mean the tkprof output), you could do the following:
Read the trace file to find the statement you're interested id - the line above it will be a +"PARSING"+ line, and will include a reference to the statement hash_value look like +'hv=3838377475845'+.
Use the hash_value to query v$sql to get the sql_id and child_number;
Use the sql_id and child number in a call to dbms_xplan.display_cursor:
PARSING IN CURSOR #7 len=68 dep=0 uid=55 oct=3 lid=55 tim=448839952404 *hv=3413100263* ad='2f6ede48'
select ... etc. (the statement I want the plan for)
SQL> select sql_id , child_number from v$sql where hash_value = *3413100263*;
SQL_ID CHILD_NUMBER
053tyaz5qzjr7 0
SQL> select * from table(dbms_xplan.display_cursor(*'053tyaz5qzjr7'*,*0*));
PLAN_TABLE_OUTPUT
SQL_ID 053tyaz5qzjr7, child number 0
select /*+ use_concat */ small_vc from t1 where n1 = 1 or n2 = 2
Plan hash value: 82564388
| Id | Operation | Name | Rows | Bytes | Cost |
| 0 | SELECT STATEMENT | | | | 4 |
| 1 | CONCATENATION | | | | |
| 2 | TABLE ACCESS BY INDEX ROWID| T1 | 10 | 190 | 2 |
|* 3 | INDEX RANGE SCAN | T1_N2 | 10 | | 1 |
|* 4 | TABLE ACCESS BY INDEX ROWID| T1 | 10 | 190 | 2 |
|* 5 | INDEX RANGE SCAN | T1_N1 | 10 | | 1 |
Predicate Information (identified by operation id):
3 - access("N2"=2)
4 - filter(LNNVL("N2"=2))
5 - access("N1"=1)
Note
- cpu costing is off (consider enabling it)Regards
