validation for each 1,000 records to be inserted in the select statement

Hi, I have the following INSERTION in the SELECT statement.
The SELECT statement (who joined) data fo about 6 crores. I need to insert this data into another table.

Please suggest me the best way to do it.
I use the INSERT in the SELECT statement, but I want to use the statement commit for each 1,000 records.

How can I do this...

insert into emp_dept_master 
 select e.ename ,d.dname ,e.empno ,e.empno ,e.sal 
   from emp e , dept d
  where e.deptno = d.deptno       ------ how to use commit for every 1000 records .

Thank you

Method 4 is the best

You could combine method 3 and 1 (without dynamic SQL)

Method 2 is the less optimal solution from the list.

Menu Module v2 supported for the selected state?

I can't understand if v2 menu module supports the selected state. I remember reading somewhere that it was planned to produce in the future, but it seems that the file /ModuleTemplates/Menu/Default/container.html has accommodations for her.
A resource if so, it would be appreciated.

By default I did, the JavaScript code is there in the updates page and not different from the normal version in this respect.

Record is not inserted into the transparent Table Forms 10g
Hi all

I have the built in 10g (10.1.2.0.2) form.

Basically, the form has 2 blocks.
1 block with a single element, where we enter a value and press on enter (this place you block2 and run the query).
Block 2 (tabular) will get the records. This block2 have now 3 columns (caseid, userid, date).

Now when I insert a new record, I just need to get the caseid only. And username and date must be filled in automatically.
I can fill fields username and the DATE.
And when I enter a value element of the block 2 caseid and then Control + S(to insert the record and Save the transaction),.
I get the message saying FRM-40400: transactions: 1 applied and saved records.
But when I ask again for the same thing, I do not have is the record inserted into the table.
Why is this happening?

Help please...
Drop the trigger for INSERTION WE (do not comment code or write NULL) and move your code to INSERT before trying.

In general, Yes, if the function is a function table, you can do something like:
```
select  t.col1,
        t.col2,
        f.col1,
        f.col2,
        f.col3
  from  table_name t,
           table(some_table_function(param1,...paramN)) f

Not finding the correct syntax for the select statement

Hello

The following statement works very well and gives the expected results:

prompt
prompt Using WITH t

with t as
  (
   select a.proj_id,
          a.proj_start,
          a.proj_end,
          case when (
                     select min(a.proj_start)
                       from v b
                      where (a.proj_start  = b.proj_end)
                        and (a.proj_id    != b.proj_id)
                    )
                    is not null then 0 else 1
          end as flag

          from t t2
         where t2.proj_end <= t.proj_end
       ) s
  from t;

As an academic exercise, I wanted to rewrite the above statement without using the WITH clause, I tried this (amongst dozens of other tests - I hit a mental block and cannot understand):

I found that someone else has had this problem, but solution of Matt necessary use of the configuration editor. I followed the instructions, but by clicking on the Advanced tab, there was no Config Editor tab in order to execute the next step of the solution.

Media Center is Reporting insufficient disk space for each record programmed

Since the upgrade to Windows 8 Media Center reports that there is not enough disk space for each scheduled TV recording despite there are currently more than 1 TB of free space. The programs record very well, but it is impossible to tell when it is a genuine issue (for example, a program conflict) as an indicator of each scheduled recording is also problematic.

There is a simple solution to this in Media Center as an administrator (which implies that there may be a problem of permissions with Windows 8). However, I also use an XBox 360 as an Extender and there is no known method to apply this workaround to an Extender then it continues to be a lack of disk space for each unique record.

I tried completely removing the recorded TV folder, followed by a reboot to allow Media Center services recreate the folder, but it does not solve the problem. I checked all the settings and Media Center reports that it has enough free space to save more than 400 hours of television, but he's still complaining lack of disk space for each individual scheduled recording.

Any ideas?

I found a solution that worked for me on another thread.

See the post from Steve Scoltock on executing a recovery job in the computer management application, here:

http://answers.Microsoft.com/en-us/Windows/Forum/windows_8-Winapps/Windows-8-TV-recording-problem-with-Windows-Media/f9695954-246F-4C59-8d1b-3729a81feee9?page=1&TM=1352456456164

It worked for me. I hope this guy helps too.

Hello

Solution by using a loop in BPEL;
1 count the number of nodes for ReceiptDetails.
2 create a counter for loop through each node ReceiptDetails. Use a while loop in BPEL
3 search T1743512 (table) with DeliveryNo and the line. Make sure that you select the correct line from the ReceiptDetails node element node. This can be done using the counter example of xpatch ns2:ReceiptBatch / ns2:Receipt / ns2:ReceiptDetails [counter] / ns2:Line. Please use the DB adapter.
I guess that the DeliveryNo can only appear once in the document following your example.
4. for each receiptDetails you write a record in table too T2743002. Please use the DB adapter.
5. Since the time increment the counter. This is to ensure that the while loop stops at the point where the counter is greater then the number of nodes to ReceiptDetails.

I think a better solution is to make the loop in PL/SQL. It will be faster. You specify an input of type of collection in your pl/sql package parameter. Assign all items receiptDetails and DeliverNo line to the PL/SQL package. Within PL/SQL unravel you the closure. With a little luck, you have the T2743002 in the same schema to create the record too. Otherwise create synonyms of the database or database links.

Good luck

Thank you

Stored procedure or Tigger in order to update to 20,000 records every night?
Hello world

I have a question about stored procedure or trigger.

Here's the situation:

I need to empty 20,000 records in table A in the database of progress to a B in Oracle table, every night. This is done by a planner and it's fine. Now, I need to update the table C for these 20,000 records in table B, either during the discharge of A to B, or after the dump is done.

Which way you think it's better in terms of performance for 20,000 records to be updated in table C.

1 - Update table C in the discharge of A to b: specify a trigger for each record added to table B, do the update in table c. (meaning it will unleash 20,000 times)

2 - Update table C after the dump from A to B is done: specify a stored procedure and call it by a scheduler to do the update to table C (which means that the cursor must navigate 20,000 files and do the update for each of them in table C)

Any ideas would be greatly appreciated.

Mona
I agree that the second option is better, but it took me by surprise:

user2372480 wrote:
2 - Update table C after the dump from A to B is done: specify a stored procedure and call it by a scheduler to do the update to table C (* which means that the cursor must navigate 20,000 files and do the update for each of them in table C *)

I interpreted that as a record by the other treatment as in:
```
OPEN CURSOR
LOOP
-- update a single record here
END LOOP
```
If this is the case, try and combine all the updates in a single SQL statement if you can. If this is not the case, try treatment in bulk.

HTH!
