How to maintain a sequence of number for each execution of the view
Hi allI would like to implement a vision that returns the sequence number (say, at 1 and increment a (num = num + 1)) for each performance.
for example, first, it should be 1 and then for the excution second it takes 2...
What is the best way to implement this scenario?
Please advice me...
Thank you
You cannot do it directly:
SQL> create sequence s
2 /
Sequence created.
SQL> create view s_view
2 as
3 select s.nextval s_value
4 from dual
5 /
select s.nextval s_value
*
ERROR at line 3:
ORA-02287: sequence number not allowed here
You could:
SQL> create or replace
2 function s_func
3 return number
4 is
5 v_retval number;
6 begin
7 select s.nextval
8 into v_retval
9 from dual;
10 return v_retval;
11 end;
12 /
Function created.
SQL> create view s_view
2 as
3 select s_func s_value
4 from dual
5 /
View created.
SQL>
However, sequence will be calculated that whenever view column is referenced:
SQL> select ename,
2 s_value
3 from emp,
4 s_view
5 /
ENAME S_VALUE
---------- ----------
MILLER 1
CLARK 2
KING 3
ADAMS 4
SMITH 5
JONES 6
FORD 7
SCOTT 8
JAMES 9
MARTIN 10
WARD 11
ENAME S_VALUE
---------- ----------
ALLEN 12
BLAKE 13
TURNER 14
14 rows selected.
SQL> select ename,
2 s_value,
3 s_value
4 from emp,
5 s_view
6 /
ENAME S_VALUE S_VALUE
---------- ---------- ----------
MILLER 15 16
CLARK 17 18
KING 19 20
ADAMS 21 22

FORD 27 28
SCOTT 29 30
JAMES 31 32
MARTIN 33 34
WARD 35 36
ENAME S_VALUE S_VALUE
---------- ---------- ----------
ALLEN 37 38
BLAKE 39 40
TURNER 41 42

You could create the deterministic function, but it does not guarantee still sequence value will be calculated once per request.

Hello
It makes no sense to do it in PL/SQL when you can do it with SQL.
SQL is generally more efficient than PLSQL.
And can you explain why you don't want to use analytical functions?
This will update your table using a MERGE statement and an analytic function:
MERGE INTO line_table lt USING ( SELECT ROWID rid, header_value, row_number() OVER(PARTITION BY header_value ORDER BY ROWNUM) rn FROM line_table ) src ON (src.rid=lt.ROWID) WHEN MATCHED THEN UPDATE SET lt.line_number = src.rn;
The result is less to:
HEADER_VAL LINE_NUMBER

How can I connect my Cruz Tablet for my connection to the internet the computer?
Original title: How can I connect to my cruz Tablet
How can I connect my Tablet cruz for my connection to the internet the computer
Hello
Thanks for posting your question in the Microsoft Community.
I imagine the inconvenience that you are experiencing. I will certainly help the question of fixing.
To help you suggest several steps to solve the problem, I would appreciate if you could answer the following questions:
1. What is the model of the Cruz tablet number?
2. How do you access Internet for your computer? It is through a wired connection or wireless?
Follow the steps below:
a. connect a network cable to the tablet computer if the Tablet has a network card. High-speed modems have an output connection to which you connect the network cable and then connect it to a computer or router.
b. display wireless networks in network settings options. Select a wireless network, and then click on connect. In the areas of Wi - Fi hotspot, you may need to open a Web page to accept the terms of the license before plugging in.
c. sign to a computer network or a network mobile broadband. Some tablet computers have connections to data network integrated such as the type that personal digital assistants (PDAS) and the use of cell phones. You need to register for an account with the provider of service associated with the integrated network. Alternatively, you can sign up for broadband wireless services and to access broadband that plugs into a USB port with an adapter.

You add a separate title and/or caption for each picture in the metadata Panel, and then refer to these metadata fields in the slideshow with a text field.

Loading the default limits for each execution
Hello
My situation is like this:
I spend my sequence using the sequential model. Usually, the sequence is executed, 'in the loop', which means that when once the sequential model is launched, we can test unit after unit until we want to put an end for some reason any. The sequence is load dynamically by the sequential model and download after executing the step to discharge option.
In the sequence, we use limits. Default TS limits similar to below.
All our limitations change during execution depending on what unit we test and on what stage is the unit.
Problem:
I thought that if the sequence is loaded dynamically, it is unloaded when executing the next time that the next unit will be tested the default values of the container limits will be charged (in response to being dynamically loaded and unloaded at the step which called the main sequence is executed). Unfortunately, it seems that when we realize continous test the test limits have not returned to the default value, as expected, but they are a superposition of the limits assigned by previous executions. Of course
Issues related to the:
1 are my expectations about the behavior of TS are correct?
2. how to impose default deadline to be 'reset', the default value for each run of the sequence, not only the first execution of sequential model?
MimiKLM wrote: I am worry the speed of loading, you talked about associated to your solution, but potential problems with memory. Let say, I called the main sequence of 1000 times without breaking execution. So instead of having one copy of the sequence called with wiped/reset all variables and properties I have 1000 copies in the memory. I would call it a waste to have 1000 copies only because I need to have the properties and variables deleted.
The copy exists only during the execution of the sequence. Once the execution of the sequence is complete, the copy will be destroyed/released. At least as long your code modules do not hold their own reference to it somewhere (which generally do not do).
If you call from the main sequence 1000 times in a loop, you must still do not have a runtime copy into memory at once. The difference is a new copy is created (and destroyed once that the sequence is made running) each time, rather than create a copy only once and reuse. There is a performance hit in this call of your sequence which is somewhat proportional to the size of your sequence, but unless your sequence is really huge, or test you execution is extremely fast, you probably won't see the difference.
Hope this helps to clear things up,
