• Creation of data Mart: OWB, SSIS or the use of Oracle?

  I'm working on creating a data mart as a new application for my work. I am a developer pl/sql, but I have no experience in DW. I am looking at what technology to implement this. Each instance of the project for which I work is quite complicated to deploy. Therefore, the easiest way.
  
  Could someone advise me on the use of Oracle Warehouse Builder? be useful to use it to create a simple data mart?
  
  Could I have all of the features needed in a mini - data warehouse by simply using jobs of oracle for the planning of the ETL process created in pl/sql (bulk collect) without using another tool? Is this possible? We do not want to use SSIS.
  
  The DB is 10g EE R10.2.0.1.0, but we could move to 11g as needed
  
  Help with that I will be grateful.

• Monitoring of the use of Oracle dialog

  Hello
  
  After installing JDeveloper 11.1.1.5.0 (and other versions of 11g before that) and from JDeveloper for the first time, a "Oracle use Tracking" dialog box appears with the message
  "In order to continuously improve our products, Oracle is interested in learning about the use of the product.

• Getting the line without the use of hierarchical query values

  Hi all
  
  
  I want to know the hierarchical values without using a hierarchical query. I have two tables EMP, DEPT
  
  EMP table is to have two columns (empid, mgrid)
  DEPT table is to have two columns (deptid, empid)
  
  Data of the EMP
  
  1,
  2, 1
  3, 2
  4, 3
  
  Data DEPT
  
  10, 1
  
  Each time, I gave deptid = 10, I need to know the this deptid empid then who is this empid (child levels as well). In this case, the output should be
  1
  2
  3
  4
  
  I don't want to use hierarchical query.
  
  Thanks in advance.
  
  
  Thank you

  You can use the RECURSIVE subquery, if you are 11 GR 2, like this

  SQL> with EMP (empid,mgrid) as
    2  (
    3  select 1,null from dual union all
    4  select 2, 1 from dual union all
    5  select 3, 2 from dual union all
    6  select 4, 3 from dual
    7  ),
    8  dept(deptid,empid) as
    9  (
   10  select 10, 1  from dual
   11  ),
   12  t(empid,mgrid) as
   13  (
   14  select empid,mgrid
   15  from emp e
   16  where empid in (
   17      select d.empid
   18      from dept d
   19      where deptid = 10
   20                  )
   21  union all
   22  select e.empid,e.mgrid
   23  from emp e, t
   24  where e.mgrid = t.empid
   25  )
   26  select *
   27  from t;
  
       EMPID      MGRID
  ---------- ----------

           3          2
           4          3
  

  Yet, the question is valid - why can't use you a hierarchical query?

• Question the use of the certificate for ODSEE 11.1.1.7.0

  Hello

  I have a few questions about certificates.

  (1) do I need to renew the original self-signed certificates created when the DS was created, if I'm not currently using the secure port?

  (2) do you have any suggestions as to a good resource to explain the use and implementation of certificates in ODSEE?

  Thank you

  Bill

  Hello

  Use of ldaps (LDAP over SSL) is optional, so no need to renew the certificates if you do not use encryption to access or LDAPS attribute

• 'CREATE JAVA' error: ORA-29506: derived from the USING clause invalid query

  Hello
  
  I created a table with the following attributes:
  
  name varchar2 (200);
  LOB_DATA blob
  
  
  I loaded a java source file in the lob_data blob.
  
  I then called the SQL:
  
  create or replace and compile the java source named "RemoteCommand" using blob
  Select lob_data from str_blob_table where name = 'RemoteCommand.java ';
  
  and I get the error:
  
  ORA-29506: invalid query from the USING clause
  ORA-00936: lack of expression
  29506 00000 - "query invalid derived from USING clause.
  * Cause: The USING clause does not form a valid query.
  * Action: Correct the USING clause.
  
  
  
  If I simply copy and paste the query part of the USING clause:
  
  Select lob_data from str_blob_table where name = 'RemoteCommand.java ';
  
  I get a valid result in SQLDeveloper.
  
  
  Any thoughts on what is happening here?
  
  A few notes:
  1. it is a 8i database.
  2. it works very well on a 9i database, but according to the SQL reference for 8i, it should work as well.
  
  Thank you
  Brent

  Try to delete "select" in the USING clause, that is to say change the SELECT BLOB SUPPORT... for BLOB to HELP... The original form of the syntax of JAVA to CREATE did not expect the SELECT token must be explicitly provided. Somewhere between 8i and 9i the parser was changed to try the provided text as well as what, with SELECT prefixed. So a CREATE JAVA statement you tried working in 9i but in 8i fails because SELECT would always be added before you try using the clause as a query, resulting a SELECT duplicate token.

• rules of the clues in the text and oracle query using matches

  Dear all,
  
  I would like to ask questions about the function of rules and matches the oracle text.
  I followed a lead in the oracle text application developer guide.
  I have a table of rules like this:
  
  1 oracle
  2 larry or ellison
  3 oracle and text
  market share 4
  
  Then I create an index in this table. This is necessary for the matches function call. Here's the syntax:
  
  create index queryx on queries (query_string)
  indexType is ctxsys.ctxrule;
  
  Then, I noticed that the result on DR$ QUERYX$ I table as follows:
  
  0 2 2 1 LARRY (BLOB)
  MARKET 0 4 4 1 (BLOB) {MARKET} {ACTION}
  0 1 1 1 ORACLE (BLOB)
  0 3 3 1 ORACLE (BLOB) {TEXT}
  0 2 2 1 ELLISON (BLOB)
  
  What I want to ask is why do the words 'share' and 'text' appear in the DR table $ QUERYX$?
  
  When we use the function of the matches, it can search on the result of the index and therefore he walls can't find the word 'action '. Thus, when for example I ask like this:
  
  Select query_id queries where matches (query_string, "it only to share ten percent of all products sold") > 0
  
  It will give 0 results since no words in "it only to share ten percent of all products sold ' was in the index table. But in fact it could possibly be classified as category 4 rules which is "market share".
  
  I tried this in a large data set and get the same result.
  Here are my rules generated from my collection of document:
  
  1 {REQUIREMENTS of} & {ELICITATION}
  1 {REQUIREMENTS of} ~ {ELICITATION} & {ACTOR}

  Share market means that the market immediately followed word on the part of the word, so if you don't have the word share then is not a match. If she had walked or hand, then he would be looking for just one part.

  DATEs do not include fractions of a second. If you don't mind losing fractions of a second, you can simply remove them before pass the string to TO_DATE, like this

  TO_DATE ( REGEXP_REPLACE ( varchar2_column
                  , '\.[0-9]*$'
                  )
       , 'YYYY/MM/DD HH24:MI:SS'
       )
  

  REGEXP_REPLACE will remove the decimal point and any numbers after him. If the string does not contain a decimial, it is correct: REGEXP_REPLACE returns the immutable string in this case.

  If the fraction of a second is important, use a TIMESTAMP instead of a DATE column (and use the TO_TIMESTAMP instead of TO_DATE function).

• Need to improve the performance of oracle query

  That one will be faster? can you provide some statistical data. It will be good if you share an oracle for this documentation.
  
  Thank you

  Well, that's your requests, your data contained in your database, on your hardware... Anything that can have an impact. So who better to check if there is no difference in performance than yourself?

  Enable SQL tracing, run the statements, then analyze trace (with the help of tkprof or similar) files and look at the differences.

• How to use a parameter query to select and display the data in the table of the façade

  I am using Access 2007 database
  I want to select the specific data in the database using control of the chain as 'select product, size, weight of ProductInfo where barcode (chain control) =?'  and also display the same table of façade.

  I use the connected database toolkit.
  I saw the example of the parameterized insert, but it did not help to use parameterized select query, as well as to display data of parameterized select query.

  I looked for example on parameterized select query, but I don't have any.
  So pls guide me how to do this. I would like to know the other method (if any) that the use of parameter query to perform the same thing.

• Generate a page based on a query variable in another page?

  Hello. I am trying to generate a page based on data from a single line in a table (not a report, such as the look of the page may be in a table). I've set up a report containing a list of all the lines where the first column consists of links; each link loads the new page and sends the value of the display of the link as a query variable.
  
  How to access the database without having to create a report? I think that PL/SQL and dynamic content is involved, but my knowledge in Application Express is Rusty at best.

  If you have a page parent with a report, you can create a column in the column link properties and link, you would choose an image and the elements on your page in which target you want to pass your values:

  1. report of the attributes / add column link (link on the right side)

  2. change your link column and go to the section "links in the column".

  3. choose the link image

  4. indicate your target page

  5 specify the (probably hidden) element on your page target to pass values to

  6 specify the column that contains the value of the key

• The use of bind variables in dynamic query created for Ref Cursor

  Hello
  
  I'm in a situation where there is a Ref cursor to which the query is built execution based on a loop. This is why the number of links would be known until the program runs.
  The application is currently using literals instead of bind variables.
  
  code snippet of the above is
  strSql: = "select * from emp where 1 = 1 and ().
  
  loop cursor1
  If cond is true then
  strSql = strSql | "ename = ' |" Cursor1.ColumnName;
  end loop;
  
  Open cursor2 for strSql;

  He's referring to the coding style. He is currently using concatenated literal, and the goal is to change it to use the bindings.

  If I understand this it is known as method 4 dynamic SQL and requires DBMS_SQL. There are examples autour but they vary according to the type of statement being generated - SELECT statements require column lists to be parsed, unlike the INSERT/UPDATE/DELETE.

  This came up recently on my current project and I hit a demo. Here a table of names and values accepted procedure and had to build these in a single WHERE clause along the lines of

  AND t_names(i) = t_values(i)
  

  for an undetermined number of elements in the array. For this demonstration, I used a table that we called "attribute" (don't ask) which has columns including 'attribute_id' and 'name', and I need to build a query along the lines of

  select description from attribute where attribute_id = :b1 and name = :b2
  

  by the way '1012' and 'ISIN' respectively. (I use a table better and after a CREATE statement for her but I have to rush right now, sorry).

  declare
     k_sql_base        constant varchar2(500) := 'select description from attribute';

• Question about the use of constant variables in forms

  As I am still very new to forms, please forgive my ignorance, if the answer to my question is very simple. I'm trying to understand how to use constant variables in my application Forms. For example, if I want the return code of constants for the configuration application (not, mind these are examples):
  
  RC_SUCCESS CONSTANT PLS_INTEGER: = 1;
  RC_FAILURE CONSTANT PLS_INTEGER: = 0;
  RC_YEAR_DATA_NOT_FOUND: = 50;
  
  Then in a module I created, if I wanted to check the return code against one of the constants I would do:
  
  DECLARE
  RC PLS_INTEGER;
  BEGIN
  GET_YEAR_DATA ('2000 ', rc);
  IF rc = RC_YEAR_DATA_NOT_FOUND THEN
  -Make an error handling
  END IF;
  END;
  
  I know that you can declare constants within the individual procedures or packages, but I can't find information on how to do it in the world for the application. I read on the use of global variables in forms, but only the CHAR data type and the fact that the value can be modified doesn't really fit for this purpose have I missed something? Is there a config file or something for the Web server that can be used to configure these?
  
  Any help would be appreciated.
  
  Thank you

  To declare constants create a Package specification in a pll and deifne all your vitals, something like:

  PACKAGE PK_CONSTANTS IS
    RC_SUCCESS CONSTANT PLS_INTEGER := 1;
    RC_FAILURE CONSTANT PLS_INTEGER := 0;
    RC_YEAR_DATA_NOT_FOUND := 50;
  END;
  

  Then attach this pll for all your forms-modules and use it as

  IF rc = PK_CONSTANTS.RC_YEAR_DATA_NOT_FOUND THEN
    ..
  END IF;
  

  A word on exceptions or errors: to me more clear (and in the case of exceptions even better) to throw an exception only to hide behind return-codes.
