How to generate oracle sequence using Database Designer Transformer

I created Entity Relationship Diagram.I can generate Table relavant to that every entity.(using Database Design Transformer).Normaly the Database Design Transformer tries to find a suitable unique key that can be used as the primary key. If it cannot find one, it creates a surrogate primary key.it create sequence for that surrogate key.But I didn't want that.I want generate sequence only the attribute that have primary key.how can i do

So a digital pulse??

How to prevent Oracle from using an index when joining two tables ...

How to prevent Oracle from using an index when joining two tables to get an inline view which is used in an update statement?
O.K. I think I have to explain what I mean:
When joining two tables which have many entries sometimes it es better not to use an index on the column used as join criteria.
I have two tables: table A and table B.
Table A has 4.000.000 entries and table B has 700.000 entries.
I have a join of both tables with a numeric column as join criteria.
There is an index on this column in table A.
So I instead of
where (A.col = B.col)I want to use
where (A.col+0 = B.col)in order to prevent Oracle from using the index.
When I use the join in a select statement it works.
But when I use the join as inline view in an update statement I get the error ORA-01779.
When I remove the "+0" the update statement works. (The column col is unique in table B).
Any ideas why this happens?
Thank you very much in advance for any help.
Regards Hartmut

I think you should post an properly formatted explain plan output using DBMS_XPLAN.DISPLAY including the "Predicate Information" section below the plan to provide more details regarding your query resp. update statement. Please use the \[code\] and \[code\] tags to enhance readability of the output provided:
In SQL*Plus:
SET LINESIZE 130
EXPLAIN PLAN FOR <your statement>;
SELECT * FROM TABLE(DBMS_XPLAN.DISPLAY);Usually if you're using the CBO (cost based optimizer) and have reasonable statistics gathered on the database objects used the optimizer should be able to determine if it is better to use the existing index or not.
Things look different if you don't have statistics, you have outdated/wrong statistics or deliberately still use the RBO (rule based optimizer). In this case you would have to use other means to prevent the index usage, the most obvious would be the already mentioned NO_INDEX or FULL hint.
But I strongly recommend to check in first place why the optimizer apparently seems to choose an inappropriate index access path.

How to generate Webservices.xml using tool in Sun One App Server?

How to generate Webservices.xml using tool in Sun One App Server?

Hi,
The build.xml file should be in a directory from where
you are running the asant command.
To resolve the common.xml file not found error,
open your build.xml and check from which location the common.xml file is incuded.
In the sample application it is four directories above
the directory where build.xml is located.
You can copy the common.xml in the current directory and then change the following in your build.xml
<!ENTITY include SYSTEM "../../../../common.xml">
to <!ENTITY include SYSTEM "common.xml">
Hope this helps.
Get back in case you have more issues

How to generate pwm pulse using NI DAQ in MATLAB

hi everyone. please tell me how to generate pwm pulses using Ni DAQ card in MATLAB Simulink. if through coding is possible then post the corresponding code.....reply me

Make sure you have installed the Measurement studio support for VB 6.0 then you will be able to find examples in the folder below on win7 and 8.
C:\Users\Public\Documents\National Instruments\NI-DAQ\Examples
Narrow down to Analog Output and choose update voltage example for measurement studio.
You also have the possibility to use DAQ assistant if you have measurement studio installed. This function is a configuration type programming. After going through the configuration Wizard code is automatically scripted for you so that you can output the voltage you need. Read more about DAQ assistant in the blow link.

How to create a sequence using Toplink for DUAL table

Hi All,
How do I create below sequence using TOPLINK

Dheeraj

Hi Dheeraj,
Sequence Object should be created in Database and specify the type of sequence that will be used in toplink to create sequence value.For example,sequence objects created in database needs to be configured using Native Sequence.
For more information refer to the below link.Use JDeveloper Toplink Wizards for declarative programming of Toplink native Sequencing.

How to generate PN sequence?

Thank you in advance.
Now I'm converting Matlab codes into a LabVIEW code. While doing it, I don't know how to generate a PN sequence that I generated on Matlab using 'commsrc.pn' or 'seqgen.pn' function. I searched some threads, and found out that the Binary MLS VI can generate it, but I'm not sure it will generate the same sequence or not. Can anyone help me with this?

Does the PN sequence need to follow a particular distribution or constrain?
Kudos and Accepted as Solution are welcome!

How to find Oracle is using swap space or not?

Hi,
I have a SuSe Linux database server on which 2 Oracle 10g databases and one MySQL server is running.
I can see a very little swap space is being used in the server while there is almost 100% RAM utlization.
I want to know if my Oracle databases are using swap or not. If it is using, how much of swap being used currently by each Oracle database?
Can someone please guide me on how to do that?
Thanks in advance for your help.

How to generate random sequence numbers

Hello experts
Iu2019m writing a custom program and pulling data from VBAK & VBAP. As per requirement I also need to generate a sequence number randomly and finally store all data in text file and upload at server. The hiccup is I donu2019t know how to generate sequence numbers. Can somebody please show me how I can accomplish it?
Thanks a lot in advance

Find the below code,
data: lv_range type datatype-char0128.
call function 'RANDOM_C'
    exporting
      len_min   = 20
      len_max   = 20
      char_min = 1
      char_max = 20
    importing
      rnd_value = lv_range.
LV_RANGE param will have a random value..
If you need number you can use the FM "RANDOM_I4"
Thanks,

How to tell Oracle to use spindles efficiently?

I am creating an Oracle database on a server that has multiple disks and is running a RAID set. How do I tell Oracle to use all the disk spindles efficently by striping the data across all disks on the server?
Thank you!

I'm not using 8.0.5 anymore; I'm using 8.1.7, so I can't test
any theories on what will work in 8.0.5, but I believe I
remember that the "PRAGMA RESTRICT_REFERENCES (WNDS);" was only
required for packaged functions. Can you compile your function
all by itself, outside of the package, and just call it from
some procedure within the package? I think that would eliminate
the conflict between WNDS and DBMS_SQL.PARSE. I did a little
testing and the following seemed to work:
CREATE OR REPLACE FUNCTION GetMaxNum
(nTable IN VARCHAR2,
   year   IN NUMBER)
RETURN     NUMBER
IS
cid        INTEGER;
rows       INTEGER;
n          NUMBER (6);
BEGIN
cid := DBMS_SQL.OPEN_CURSOR;
DBMS_SQL.PARSE (cid,
      'SELECT    MAX (numero)'
|| ' FROM ' || nTable
|| ' WHERE     TO_NUMBER(TO_CHAR(date_,''YYYY''))='
              || year,
DBMS_SQL.NATIVE);
DBMS_SQL.DEFINE_COLUMN (cid, 1, n);
rows := DBMS_SQL.EXECUTE_AND_FETCH (cid, FALSE);
IF rows > 0
THEN
    DBMS_SQL.COLUMN_VALUE (cid, 1, n);
ELSE
    n := 0;
END IF;
DBMS_SQL.CLOSE_CURSOR (cid);
RETURN n;
EXCEPTION
WHEN OTHERS THEN
    DBMS_SQL.CLOSE_CURSOR (cid);
RAISE;
END GetMaxNum;
CREATE OR REPLACE PACKAGE GetMaxNumber_pkg
AS
PROCEDURE GetMaxNumber
    (nTable IN VARCHAR2,
     year   IN NUMBER);
END GetMaxNumber_pkg;
CREATE OR REPLACE PACKAGE BODY GetMaxNumber_pkg
AS
PROCEDURE GetMaxNumber
    (nTable IN VARCHAR2,
     year   IN NUMBER)
IS
    n          NUMBER (6);
BEGIN
    SELECT GetMaxNum (nTable, year)
    INTO   n
    FROM   dual;
END GetMaxNumber;
END GetMaxNumber_pkg;

DISPLAY not set.
Set DISPLAY environment variable, then re-run.
How to set DISPLAY environment variable.
Thanks,
Rafi.

Normally, you set DISPLAY to an IP address with the suffix : and 0.0: the IP address must match a machine able to display X11 windows.
Example with Linux bash shell:
export DISPLAY=192.168.0.1:0.0What is your OS version ? What is your shell (bash, ksh, sh, csh) ? How do you connect to the UNIX host ?
