NULL values are inserted into interface table for read only columns

Hi, I developed a custom Integrator where some of the columns has to be displayed as read only in the layout. I am using SQL content to populate the data. When I upload the data NULL values are inserted into table interface? Is there any work around for this?
Thanks

Doesn't WebADI drive you insane at times?
I must say, when it's all working it looks great and it is very user friendly (end-user that is, NOT for developers!) but before you get to that stage… please please Oracle invest some time making Web ADI a bit more logical an coherent, get the obvious bugs out, please let us not have to update BNE tables anymore to get things done.
Anyway, I sorted this one out by setting the Width to zero (0) in the Layout. HTH.

How to Improve inserts into Template table for Query Processing

Hi guys!
I need your advice. How can i improve inserts into template table (/BI0/0P00000010 for exemple)? In my scenario i forced to load data from cube C_X to cubes C_1, C_2 and C_3.
To get a goal i created a transformations and a DTP process with delta upload to each of cubes (C_1, C_2, C3). And that proccess takes about 3 hours! (it doesn't matter 1.000 or 100.000 records). But when i tried to load data with full update (with a filter) a proccess get data takes about 1 minutes.
I traced process and saw that inserting into template table (which create each time when proccess started) take the longest time. How can i improve it?

Hi Mahendar,
It will require some efforts to investigate it so I propose to open a support ticket with Microsoft (through portal).
Your first question interest me and I am not sure if you are doing proactive or reactive real time reporting. You can try with
HBase for storing and retrieving data. HBase known for providing good read and write speed. If you are not comfortable writing HBase syntax then you can add an abstraction layer i.e. HIVE. It might take little more time when you
query HBase from Hive.
If you are doing real time analytic, then you can choose from Strom and Microsoft Azure Stream Analytic.

Incorrect data value when insert into oracle table

Would like to ask expert here, how could I insert data into oracle table where the value is 03 ? The case is like that, the column was defined as varchar2(50) data type, and I have a csv file where the value is 03 but when load into oracle table the value become 3 instead of 03.

implicit datatype conversion to NUMBER can result in leading zero to be eliminated.

Upload csv file and insert into a table for user

Hello,
i want to create a Page on which, the User of my Application can upload a semicolon delimited file and the data of the file should automatically be stored in a table.
I can upload the file and the file is then stored in the htmldb_application_files table.
But I do not no how to parse the file....
Can anyone help me or is there anyone who have done that before?
Thank you,
Tim

Tim...
Here is what I did in a similar situation.
Let the user download a csv file to use as an excel turnaround document.
I check digit the primary key. They are not supposed to touch that column.
They do their excel thing adding data in columns next to the ones they are updating. They now have the original and new data on the same row in the excel document. They save it on a share drive as a csv. A perl script wakes up and parses the csv. Verify's the check digit, checks that the old values still exist in the table... etc, and then does the update if all is well at the row level. The csv is replaced showing the success or failure of the update on each row.
Probably lots of other ways to accomplish this but I have gotten years of use out of the script. The original csv can come out of almost any application. Mine come from apex, discoverer and some excel queries.

Inconsistent inserts into detail table of master-detail form

Hello,
[I am not sure if this is a bug or user error, so I've also put this in the bug tracking system. Apologize for the 'duplication']
I have a master-detail form: Orders is the master, and Order_Details is the detail. I have noticed some inconsistent behavior when inserting the detail information.
On occasion, the row will be inserted, and a null value will get inserted into the database for the first column of the detail table; all the other data values will be inserted fine. There doesn't seem to be any pattern to when it happens. I wrote down the following test steps:
1. Enter new order information and click 'Create'
2. Click 'Add Row' button so can add order detail info
3. Enter detail row information
4. Click 'Add Row' (I do this so I can see the success message that the detail data was actually inserted)
5. Click 'Apply Changes' at the master level.
I ran a query on the order details table and saw that the data inserted correctly. Then I ran the following test:
1. Enter new order information and click 'Create'
2. Click Add Row button so can add order detail info
3. Enter detail row information
4. Click 'Add Row' (success message appears that detail was inserted)
5. Enter second detail row information
6. Click 'Add Row' (success message appears that detail was inserted, however, now in the first column of that second detail row - the product name field/column - the data does not appear. I only see my null text value. The data in the first detail row is all correct)
7. Enter third row detail information
8. Click 'Add Row' (success message appears that detail was inserted, and this row's information appears correctly, as does the first row's, but the second row is still showing a null value for the product name column)
9. Click 'Apply Changes' to get out of the form
A query of the order details table shows that a null value (-) has indeed been inserted into the table for the product name column of the second detail row.
This behavior also happens when I don't have a null value for the LOV (i.e., it defaults to the first row of the lookup table).
Has anyone seen this before? Am I entering the data incorrectly?
Thanks.

Tables in read only mode

Hi friends.
In my job we insert data in some tables, in the end of the month we do some operations with this data and for the next month we use other tables.
How do I change my tables for read only mode, because is so dangerous that for error erase the old tables?

Hi,
You can revoke all privs like insert, update, delete... from all other users for these tables. Then only the owner can do some damage.
If the database user is used by many different people and you rather don't trust them, copy the 'old' tables to another schema and don't spread the password.
And most important: Have backups in place!

Creating a button for inserting into a table

What I can't do, because I've never needed to, is to create in a page (where I have a Interactive report) a button that when is clicked performs a simple sql (for example an insert into a table using some page item values).
How can I do it?
Thanks

Here are some of the steps:
1) Create the button.
2) Then right click on the button name and select Create Dynamic Action
3) Give the DA a name, click next
4) On the "When" Step, Event should already be "Click" and the button name should be filled in
5) For Condition, you would have a condition for when you want the button display. Say, if your page items have a certain range of values then display this button. No condition means the button is always displayed.
6) For the "True Action" Step, for Action select "Execute PL/SQL Code"
    [There are other ways to do this, but this is straight-forward for me.]
7) The in the PL/SQL Code block enter say:
Begin
INSERT INTO EMP (EMPNO, ENAME, HIREDATE)
          VALUES (:P6_EMPNO, 'MARK1970', :P6_HIREDATE);
COMMIT;
END;   --- You would likely make them all page item variables
8) Here the part I'm not 100% sure of.
    For "Page Items to Submit", name the page items used in YOUR QUERY -- in my example these are P6_EMPNO,P6_HIREDATE   (Note no use of & or : or . here)
    Hmm. Start by putting nothing in the "Page Items to Return".   If that fails, then try the same page items P6_EMPNO,P6_HIREDATE there as well.
[ I'm too lazy to go run this down at the moment.]
9) I think that's it.

Record not inserting into the table through Forms 10g

Hi all,
I have created a form in 10g(10.1.2.0.2) based on just one table that has 4 columns(col1, col2, col3, col4).
Here col1, col2 and col3 are VARCHAR2 and col4 is date and all the columns are not null columns(There are no primary and foriegn key constrains, which means duplicates are allowed).
My form contains 2 blocks where block 1 has one text item (col1) and 3 buttons (Delete, Save, Exit).
And block2 is a database block and has col2,col3,col4 which are in tabluar layout frame displaying 10 records.
When the form is opened the cursor has to be in block1.col1 for querrying. Here i enter a value in col1, and then when I click on col2 in the block2, then I put execute_query in new_block_instance of block2, which displays the records.
The block2 properties are not updatable, insertable and query is allowed.
Everything is working good until here. But here in the block2 when I want to insert another record into the table, by navigating all the way down to the last empty record and entering the new values for col2, col3 and col4 And then Ctrl+S will display the message "*FRM-40400: Transaction complete: 1 record applied and saved.*" But actually the record is not inserted into the table.
I also disabled the col4 by setting the Enabled property to No, since while inserting new record the date have to be populated into it and it shouldnt be changed by the user. And im populating the sysdate into the new record by setting Intial Value property to *$$DATE$$*.
And another requirement which I could not work arround here is that, the col3 also should be populated with the username of the user while inserting.
please help me...

Hi Sarah,
I do not want to update the existing record. So I kept Udate Allowed to No in property palette for the items in block2.
Do I have to do this property at block level also?
I'm inserting a new record here.

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.

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:
CREATE VIEW New_Documents (new_doc_id)

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

How can I insert into a table other than the default table in a form

Hi,
I want to insert into a table with some fields value of a form of another table. I have written insert code On successful submission of that form, but after submit it gives the following error
An unexpected error occurred: ORA-06502: PL/SQL: numeric or value error (WWV-16016)
My code is like this
declare
l_trn_id number;
l_provider_role varchar2(3);
l_provider_id varchar2(10);
begin
l_trn_id := p_session.get_value_as_number(p_block_name=>'DEFAULT',p_attribute_name=>'A_TRANSACTION_ID');
l_provider_id := p_session.get_value_as_varchar2(p_block_name=>'DEFAULT',p_attribute_name=>'A_PROVIDER1');
l_PROVIDER_ROLE := p_session.get_value_as_varchar2(p_block_name=>'DEFAULT',p_attribute_name=>'A_PROVIDER_ROLE1');
if (l_provider_role is not null) and (l_provider_id is not null) then
insert into service_provider_trans_records(service_provider_id,transaction_id,role_type_id)
values(l_provider_id, l_trn_id, l_provider_role);
commit;
end if;
end;
Where 'PROVIDER1' and 'PROVIDER_ROLE1' are not table fields.
How can do that or why this error comes ? Any idea?
Thanks
Sumita

Hi,
When do you get this error? Is it while running or while creating the form.
Here is a sample code which inserts a non-database column dummy into a table called dummy. This is done in successful procedure.
declare
l_dummy varchar2(1000);
begin
l_dummy := p_session.get_value_as_varchar2(p_block_name=>'DEFAULT',
p_attribute_name=>'A_DUMMY');
insert into sjayaram903_1g.dummy values(l_dummy);commit;
end;
Please check in your case if the size of the local variable is enough to hold the values being returned.

Diffrence between backend insert and front end insert into a table.

I am developing a conversion program for tax exemption. For this program only ZX_EXEMPTIONS table is used to populate the data and we got confirmation from Oracle also regarding this.For inserting the data into this table we are taking the max of tax_exemption_id which is pk for this table and adding one to it and inserting into the table. But problem here is after inserting from back end we are not able to insert from front end.
It seems backend data is holding the tax_exemption_id which is suppose to reserve by front end data.Please explain the different behavior of populating of tax_exemption_id from front end and back end.

Hi,
i think the problem is that you are using max-value + 1 for tax_exemption_id. But as ZX_EXEMPTIONS is using sequence ZX_EXEMPTIONS_S
for primary key generation, you encounter situation that you are increasing PK Id for this table without increasing sequence value.
When trying to insert rows from front end - which probably uses sequence value - it tries to use a sequence value already used by your backend
process (which generated it by Maxvalue + 1) and would then encounter a primary key violation.
I think you should use sequence mentioned above to generate your PK Ids in backend process as well. And before doing so, check current value
of ZX_EXEMPTIONS_S, as you might need to rebuild the sequence in order to select nextval sucessfully for both frontend and backend.

How to insert into 2 tables from the same page (with one button link)

Hi,

email varchar2(50)
hire_date date
dept_id number
PK = emp_id
FK = dept_id
Notes
note_id number not null
added_on date not null
added_by varchar2(30) not null
note varchar2(4000)
emp_id number not null
PK = note_id
FK = emp_id
I want to do an insert into both tables via the application and also via the same page (with one button link). I have made a form to add an employee with an add button - adding an employee is no problem.
Now, on the same page, I have added a html text area in another region, where the user can write a note. But how do I get the note to insert into the Notes table when the user clicks the add button?
In other words, when the user clicks 'add', the employee information should be inserted into the Employees table and the note should be inserted into the Notes table.
How do I go about doing this?
Thanks.

Taking More Time while inserting into the table (With foriegn key)

Hi All,
I am facing problem while inserting the values into the master table.
The problem,
Table A -- User Master Table (Reg No, Name, etc)
Table B -- Transaction Table (Foreign key reference with Table A).
While inserting the data's in Table B, i need to insert the reg no also in table B which is mandatory. I followed the logic which is mentioned in the SRDemo.
While inserting we need to query the Table A first to have the values in TableABean.java.
final TableA tableA= (TableA )uow.executeQuery("findUser",TableA .class, regNo);
Then, we need to create the instance for TableB
TableB tableB= (TableB)uow.newInstance(TableB.class);
tableB.setID(bean.getID);
tableA.addTableB(tableB); --- this is for to insert the regNo of TableA in TableB.. This line is executing the query "select * from TableB where RegNo = <tableA.getRegNo>".
This query is taking too much time if values are more in the TableB for that particular registrationNo. Because of this its taking more time to insert into the TableB.
For Ex: TableA -- regNo : 101...having less entry in TableB means...inserting record is taking less than 1 sec
regNo : 102...having more entry in TableB means...inserting record is taking more than 2 sec
Time delay is there for different users when they enter transaction in TableB.
I need to avoid this since in future it will take more time...from 2 sec to 10 sec, if volume of data increases mean.
Please help me to resolve this issue...I am facing it now in production.
Thanks & Regards

Hello,
Looks like you have a 1:M relationship from TableA to TableB, with a 1:1 back pointer from TableB to TableA. If triggering the 1:M relationship is causing you delays that you want to avoid there might be two quick ways I can see:
1) Don't map it. Leave the TableA->TableB 1:M unmapped, and instead just query for relationship when you do need it. This means you do not need to call tableA.addTableB(tableB), and instead only need to call tableB.setTableA(tableA), so that the TableB->TableA relation gets set. Might not be the best option, but it depends on your application's usage. It does allow you to potentially page the TableB results or add other query query performance options when you do need the data though.
2) You are currently using Lazy loading for the TableA->TableB relationship - if it is untriggered, don't bother calling tableA.addTableB(tableB), and instead only need to call tableB.setTableA(tableA). This of course requires using TopLink api to a) verify the collection is an IndirectCollection type, and b) that it is hasn't been triggered. If it has been triggered, you will still need to call tableA.addTableB(tableB), but it won't result in a query. Check out the oracle.toplink.indirection.IndirectContainer class and it's isInstantiated() method. This can cause problems though in highly concurrent environments, as other threads may have triggered the indirection before you commit your transaction, so that the A->B collection is not up to date - this might require refreshing the TableA if so.
Change tracking would probably be the best option to use here, and is described in the EclipseLink wiki:

Fetch data from two tables and insert into one table

I have similar to the following data in two tables (@Plant, @PlantDirector) and need to consolidate into one table (@PlantNew) as follows.
DECLARE @Plant TABLE (PlantID INT, PlantName VARCHAR(100))
INSERT INTO @Plant (PlantID, PlantName) VALUES (1, 'Name One'),(2, 'Name Two'),(3, 'Name Three'),(4, 'Name Four'),(5, 'Name Five'),(6, 'Name Six')
Director data for the Plants exist in the following table. Assistant value 1 means Assistant Director and 0 means Director.
Data exists only for subset of plants and a Plant may have one or both roles.
DECLARE @PlantDirector TABLE (PlantID INT, PlantDirectorID INT, Assistant bit)
INSERT INTO @PlantDirector (PlantID, PlantDirectorID, Assistant) VALUES (2, 111, 1),(2, 222, 0),(4, 333, 0),(6,444,1)
The above data needs to be inserted into one table (@PlantNew) as follows:
PlantID in @Plant table is IDENTITY value and needs to be inserted as-is into this table.
PlantDirExists will get a value of 1 if at least one record exists in @PlantDirector table for a PlantID. PlantAssistantDirID and PlantDirID should be set to the corresponding PlantDirID or NULL appropriately depending on the data.
DECLARE @PlantNew TABLE (PlantID INT, PlantName VARCHAR(100), PlantDirExists bit, PlantAssistantDirID INT, PlantDirID INT)
INSERT INTO @PlantNew (PlantID, PlantName, PlantDirExists, PlantAssistantDirID, PlantDirID)
VALUES (1, 'Name One', 0, NULL, NULL),(2, 'Name Two', 1, 111, 222),(3, 'Name Three', 0, NULL, NULL),(4, 'Name Four', 1, NULL, 333),(5, 'Name Five', 0, NULL, NULL),(6, 'Name Six',1, 444, NULL)
How do I achieve the above using SQL ? Thanks.

like this
INSERT @PlantNew (PlantID, PlantName, PlantDirExists, PlantAssistantDirID, PlantDirID)
SELECT p.PlantID,
p.PlantName,
CASE WHEN pd.PlantID IS NULL THEN 0 ELSE 1 END,
PlantAssistantDirID,
PlantDirID
FROM @Plant p
LEFT JOIN (SELECT PlantID,
MAX(CASE WHEN Assistant = 1 THEN PlantDirectorID END) AS PlantAssistantDirID,
MAX(CASE WHEN Assistant = 0 THEN PlantDirectorID END) AS PlantDirID
@PlantDirector
GROUP BY PlantID)pd
ON pd.PlantID = p.PlantID
Please Mark This As Answer if it helps to solve the issue Visakh ---------------------------- http://visakhm.blogspot.com/ https://www.facebook.com/VmBlogs
You're missing a FROM
insert into @PlantNew

PlantAssistantDirID,
PlantDirID
FROM @Plant p
LEFT JOIN (SELECT PlantID,

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.
Thanks for looking.
