Insert into temporary table

I migrate procedures MS SQL Server to Oracle.
In MS SQL SSERVER the use of instructions INSERT with procedure results which are in storage or dynamic instructions EXECUTE in place of VALUES clause is permissible. This construction is similar to INSERT/SELECT but we have to do with EXEC instead of SELECT. The part of EXEC should include exactly one resulted collection about the equivalent types to the types of table columns. In case of the stored procedure, we can pass on proper parameters, use the form of EXEC('string') and even call up wideranging procedures or remote control procedures from different servers. Calling up remote control procedures from different server, which place data in temporary table, and later realizing join with obtainable data, we can construct diffuse joins.
For example. I want insert results stored procedures sp_configure, proc_obj in temporary table.
1)INSERT #konfig
exec sp_configure.
2)
CREATE PROCEDURE proc_test
@Object_ID int,
AS
SET XACT_ABORT ON
BEGIN TRAN
CREATE TABLE #testObjects ( Object_ID int NOT NULL )
INSERT
#testObjects
EXEC
proc_obj @Object_ID,3,1
COMMIT TRAN
RETURN(0)
go
I don't know how migrate for example code to Oracle? Please examples in pl/sql.
Best regards.

Direct Path Insert into temporary table

Hi,
I made the following experiment (temp_idtable is a temp table with a single column id, V_PstSigLink is a complex View):

As you can see, with /*+ APPEND*/ there will be much less REDO generated.
How can it be?
1. /*+ APPEND*/ only doesn't mean that there shouldn't be REDO generated, does it? For that one has to declare the table with NOLOGGING.
2. In the doc there is a statement that for temp. tables there is no REDO log generated, just UNDO (and REDO only for UNDO).
Where is the difference coming from?
If I use Direct Path (APPEND) for a temp table, where will be the table populated - in the Buufer Cache or directly in a temporary segment on the disk?

Hi John,
I'm a little confused about your statement " Oracle does not cache data blocks until they are read from a table.". I wanted to make a little experiment with KEEP Buffer Cache to see weather I can 'pin' the content of a temp table. But before getting to pin I realized an interesting behavior. Please see this sqlplus log:
SQL> create global temporary table temp_ins(id NUMBER);

1 row created.
SQL> insert into temp_ins values (2);

I realized exectly the opposit of your statement! Oracle apparently cached the content of the temp table before it read from it!! Could you please explain why? Now I'm going to try it with a normal table...

Create and insert into temporary table

Dear all,
I want to create an temporary table and insert data from select statement and order data by field in that table, at the end i want to drop temporary table.
CURSOR rob_twin
IS
SELECT t.tarj, s.b24, date, status, fii, acnt, mbr, pviv, type
FROM
p6.tarj t
p6.stb24 s
p6.cuet c
WHERE .......
--now I want to create table and insert above data (from cursor rob_twin)
--after that I need to order data by t.tary from new table
--finally I want to drop this table
Thank you for your help.
Regards,
Robert

The point is in Oracle you do not create the temporary table at run-time, use it, and drop it again.
But you can create a GTT (Global Temporary Table) once and then it stays in the data dictionary, just like a normal table. The "temporary" part is simply that the data is temporary, can only be seen in this one session, and will go away either on commit or when the session ends.
So first you create a global temporary table with the columns you wish. Using either ON COMMIT DELETE ROWS or ON COMMIT PRESERVE ROWS you decide whether data in this GTT should survive across transactions or not.
Your logic could then be to populate this GTT with data from your remote database using INSERT INTO gtt_table SELECT ... FROM ...@dblink
Then work with that data in the GTT as you would with any normal local table
And finally either you simply commit your transaction and the data in the GTT goes away (if you did ON COMMIT DELETE ROWS), or you just DELETE gtt_table.
You do not continually create and drop a GTT. The table definition is permanent - it is only the data that is temporary.
Edit:
PS: As Karthick stated above - for almost any usual purposes it is likely to be possible to solve the problem without having to use GTT's. Usually even with db_links it can be done with suitable SQL and joins without having to use a GTT. But if that turns out to be one of those rare occasions where that is hard - then the above is the way to go ;-)

How to insert a table data into temporary table

Hi
Can anyone help me to insert a table data into temporary table.
Thanks
Navin

If you could provide a (simplified) example of the data you have and the output you're attempting to get, that would probably be quite helpful. I'm not sure that I understand exactly what you're trying to do here...
1) It sounds like you know the structure of the result set you're trying to generate. So it would be possible to create a temporary table once (at the same time that you create all your other tables) and write procedural PL/SQL code that would step through the data, write data to the temp table, select the data out of the temp table, and return a REF CURSOR. That would tend not to be the way that an Oracle developer would do things (there are exceptions, of course), but it would work.
2) I don't see any inherent problems in using sub-selects and inline views to do whatever aggregation you're trying to do on the secondary tables, which would allow you to get the output in a single query. For example, given an ORDERS table and an ORDER_DETAILS table,
SELECT o.customer_id, o.invoice_number, SUM( od.line_item_cost ) total_cost
FROM orders o,
order_details od
WHERE o.order_id = od.order_id
GROUP BY o.customer_id, o.invoice_number3) If you do need to use procedural logic, I would tend to look into the use of pipelined table functions or to read the data into an in-memory collection and to manipulate and return that collection.

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.
Thanks,
Sharmila

Inserting into a table which is created "on the fly" from a trigger

Hello all,
I am trying to insert into a table from a trigger in Oracle form. The table name however, is inputted by the user in am item form.
here is what the insert looks like:
insert into :table_name
values (:value1, :value2);
the problem is that forms does not recognize ::table_name. If I replace :table_name with an actual database table, it works fine. However, I need to insert to a table_name based from oracle form item.
By the way, the table|_name is built on the fly using a procedure before I try to insert into it.
Any suggestion on how can I do that? My code in the trigger is:
declare
dm_drop_tbl(:table_name,'table) // a call to an external procedure to drop the table
dm_create_tbl(:table_name,'att1','att2');
insert into :table_name
values (:value1, :value2);
this give me an error:
encounter "" when the symbol expecting one.....

Hi ,
You should use the FORMS_DDL built_in procedure. Read the on-line documentation of forms ...

Problem while inserting into a table which has ManyToOne relation

Problem while inserting into a table *(Files)* which has ManyToOne relation with another table *(Folder)* involving a attribute both in primary key as well as in foreign key in JPA 1.0.
Relevent Code
Entities:
public class Files implements Serializable {
@EmbeddedId
protected FilesPK filesPK;
private String filename;
@JoinColumns({
@JoinColumn(name = "folder_id", referencedColumnName = "folder_id"),
@JoinColumn(name = "uid", referencedColumnName = "uid", insertable = false, updatable = false)})
@ManyToOne(optional = false)
private Folders folders;
public class FilesPK implements Serializable {
private int fileId;
private int uid;
public class Folders implements Serializable {
@EmbeddedId
protected FoldersPK foldersPK;
private String folderName;
@OneToMany(cascade = CascadeType.ALL, mappedBy = "folders")
private Collection<Files> filesCollection;
@JoinColumn(name = "uid", referencedColumnName = "uid", insertable = false, updatable = false)
@ManyToOne(optional = false)
private Users users;
public class FoldersPK implements Serializable {
private int folderId;
private int uid;
public class Users implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer uid;
private String username;
@OneToMany(cascade = CascadeType.ALL, mappedBy = "users")
private Collection<Folders> foldersCollection;
I left out @Basic & @Column annotations for sake of less code.
EJB method
public void insertFile(String fileName, int folderID, int uid){
FilesPK pk = new FilesPK();
pk.setUid(uid);
Files file = new Files();
file.setFilename(fileName);
file.setFilesPK(pk);
FoldersPK folderPk = new FoldersPK(folderID, uid);
// My understanding that it should automatically handle folderId in files table,
// but it is not…
file.setFolders(em.find(Folders.class, folderPk));
em.persist(file);
It is giving error:
Internal Exception: java.sql.SQLException: Field 'folderid' doesn't have a default value_
Error Code: 1364
Call: INSERT INTO files (filename, uid, fileid) VALUES (?, ?, ?)_
_ bind => [hello.txt, 1, 0]_
It is not even considering folderId while inserting into db.
However it works fine when I add folderId variable in Files entity and changed insertFile like this:
public void insertFile(String fileName, int folderID, int uid){
FilesPK pk = new FilesPK();
pk.setUid(uid);
Files file = new Files();
file.setFilename(fileName);
file.setFilesPK(pk);
file.setFolderId(folderId) // added line
FoldersPK folderPk = new FoldersPK(folderID, uid);
file.setFolders(em.find(Folders.class, folderPk));
em.persist(file);
My question is that is this behavior expected or it is a bug.
Is it required to add "column_name" variable separately even when an entity has reference to ManyToOne mapping foreign Entity ?
I used Mysql 5.1 for database, then generate entities using toplink, JPA 1.0, glassfish v2.1.
I've also tested this using eclipselink and got same error.
Please provide some pointers.
Thanks

Hello,
What version of EclipseLink did you try? This looks like bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=280436 that was fixed in EclipseLink 2.0, so please try a later version.
You can also try working around the problem by making both fields writable through the reference mapping.

Chris

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.
Regards

How to insert into a table with a nested table which refer to another table

Hello everybody,
As the title of this thread might not be very understandable, I'm going to explain it :
In a context of a library, I have an object table about Book, and an object table about Subscriber.
In the table Subscriber, I have a nested table modeling the Loan made by the subscriber.
And finally, this nested table refers to the Book table.
Here the code concerning the creation of theses tables :
Book :
create or replace type TBook as object
number int,
title varchar2(50)
Loan :
create or replace type TLoan as object
book ref TBook,
loaning_date date
create or replace type NTLoan as table of TLoan;
Subscriber :
create or replace type TSubscriber as object
sub_id int,
name varchar2(25)
loans NTLoan
Now, my problem is how to insert into a table of TSubscriber... I tried this query, without any success...
insert into OSubscriber values
*(1, 'LEVEQUE', NTLoan(*
select TLoan(ref(b), '10/03/85') from OBook b where b.number = 1)
Of course, there is an occurrence of book in the table OBook with the number attribute 1.

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

Hi,
I have the following 2 tables....
Employees
emp_id number not null
name varchar2(30) not null
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.

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.

(old_doc_id INTEGER NOT NULL PRIMARY KEY,
group_id INTEGER,
dept_nbr INTEGER NOT NULL
REFERENCES Departments (dept_nbr));
INSERT INTO Old_Documents(old_doc_id, group_id, dept_nbr)
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),

>> I need to process the data from the above table (Old_Documents) and write into two new tables (New_Documents and New_Documents_Groups) as follows. <<
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.
Do you have a Male_Personnel and Female_Personnel table? NO! It is just Personnel!
>> old_doc_id should be stored as new_doc_id when inserting to New_Documents table. Only records [sic] with group_id NULL and one record [sic] (first [sic; no ordering in a table] one) per group should be considered (For example, old_doc_id 5 is not considered
as 3 and 5 belong to the same group_id =1) for insertion. <<
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)
AS
SELECT old_doc_id
FROM Old_Documents;
>> All records [sic] from Old_Documents should be considered for insertion into New_Documents_Groups table. The old_doc_id is inserted as new_doc_id and dept_nbr is as-is. Instead of group_id, the ID [sic: which identifier??] of the first [sic: tables
have no ordering like a deck of punch cards] record [sic] in the group should be considered as parent_new_doc_id (For example, 3 is considered as parent_new_doc_id for new_doc_id 5 as 3 and 5 belong to the same group_id in Old_Documents table) for the new_doc_id.
<<
Why not use 5 as the parent? My guess is that you are trying to form equivalence classes. See:

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
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
from @PlantDirector
GROUP BY PlantID)pd
ON pd.PlantID = p.PlantID

Insert into temporary table
