• Generate the Sql Data model ER diagram

  Hello

  I want to use the Oracle Sql Developer Data Modeler to generate ER diagram for my schema. There are a lot of tables in this schema, so I would like to exclusively identify the tables that should be selected to generate my ER diagram.

  Basically, I want these table that are related to other tables here. The reason being, if I select all the tables in the schema, and then I went to these tables in the ER diagram which have nothing to do with other tables.

  Please can anyone suggest write queries that produce this data dictionary?

  Thank you.

• How to remove empty lines of chain between the relevant data?

  I have problems with the removal of empty lines of final my data output string.  I know this is simple to do, but I'm stuck in the same train of thought.  The file is a converted hex file that is written in a series of recordings.  Convert lines it is result in fa all that data should be deleted and the number of records adjusted accordingly.  I have the code to take the file, convert, delete all of the records with F and adjust the number of files, but I'm left with a gap in my file no matter my approach I can't remove the empty spaces regularly.  I have attached the file with spaces and the goal is to remove the spaces between the blocks of code, and spaces is not always in the same direction.  Thanks for any help.  If needed I can join the code I already developed if necessary.

  Darrick

  You can read the file line by line and write back only if the length of the string <> 0.  (or maybe <> 1 in the case of the character line appears in the string to a blank line.)

  However, there is probably a way to change the code you have now so that he does not write blank lines.  Without seeing the code, it is difficult to help.

• Difference between the true Date of the Hijra with date Hijri Oracle

  Hi all
  
  I'd appreciate if someone please let me the solution for this problem. In my application, I displays the Hijri Date using the NLS parameter. but the question that "I'm dealing with a deference between the date of the real Hijra with the date of the Hijra oracle."
  
  
  Assume that the actual Hijri date 18-SEP-2012 was 02/11/1433 in hijri but in oracle was 03/11/1433
  
  When I run the following query it shows me "1433/11/03", but the actual date of the Hijra is "" 1433/11/02.
  
  Select to_char (to_date ('20120918', 'YYYYMMDD'), ' DD/MM/YYYY', ' NLS_calendar = "' |') Hegira ARABIC ') FROM DUAL;
  
  
  IFTIKHAR

  Check

  FAQ on the calendar of the Hijra (Hijri) [ID 121061.1] Arabic
  and
  Conversion algorithm to Date in the Gregorian calendar until then Arab (Hijra) [ID 130551.1]

  Support of Oracle.

  If you have a file called lxecal.nlt file

  for Oracle 8 to $9i ORACLE_HOME/ocommon/sln
  for Oracle 10 g and more $ORACLE_HOME/nls

  so maybe that's the difference you see originally.

  Kind regards

• effectiveness of the sql data warehouse and star/snowflake schema

  Hello

  We use 11.2.0.3 and need to improve the performance of queries for reports.  schema of data warehouse star/snowflake

  In addition to indexing, partitioning with star_transformation enabled etc I'm condisriing impact of the following on the performance of the queries.

  makes central (more than 1 billion lines) is associated with a client of dimesnion (a few hundred thousand lines) which in turn joined with the latest version of the dimesnion (includes approximately 30 000 lines).

  The table with a few hundred thousand lines (client dimesnion) alwsys must be questioned as stored data against the version of the customer at the time-, we wonder just latest_customer what users want to see

  the most recent version of the attributes of customer to stop data being fragemented through several lines in the report.

  If consideration would be more efficient to create a dimension that is equivalent to the customer but also stores the most recent version of the client attributes on the line-this means customer dimensuion many more columns but queries could would avoid additional research of this array of rank k 30.

  Thoughts are - it would be a material advantage?

  At the monent users request latest_customer to say would get all customers belonging to a certain multiple string.

  If change as above, then they would be interviewing the customer with a few hundred thousand lines dimension.

  Thoughts?

  Thank you

  Because a lot depends on the model of data access and data dissemination, we cannot really much more than only sb.  However, keep in mind Oracle accesses data by blocks (copies blocks and sometimes several blocks), in order to become more broad lines could have a paradoxical effect of not getting enough blocks in memory until you need it.

  It can help to visualize how data should be obtained (google something like visual sql and Karen Morton or Jonathan Lewis), as well as see the estimate and rowcounts actual imagined different plans.

• Stuck between the SQL Setup and and SQL statement

  Hello
  
  There is an important application running on my system that is to
  MEMBER OF the service.
  
  First of all I would like to explain why I used MEMBERS ',
  I'll send a string (for example: #123 #124 #125) to the query and a function converts this string in an array of number.
  Then after I use this number inside my sql table.
  
  The reason I'm using this structure, in order to generate a dynamic IN the statement inside my sql. (IF you have another solution would be great)
  
  The most important point is; When I put this statement in the Setup SQL response is only ORA-00932: inconsistent data types: expected UDT got TANK
  
  Any response will be greatly appreciated.
  
  Thank you

  Object oriented stuff almost never provides better performance on the relationship. You should stay away FROM the MEMBER If performance is a factor. Instead of:

  WHERE expr MEMBER OF nested-table
  

  I would like to test:

  WHERE expr IN (SELECT column_value FROM TABLE(nested-table))

  To extract the values you need to wait for onDataLoaded. "data" parameter is a list of cards.

• Move vCenter base SQL Express to keep only the SQL data

  Hello, I found several articles on moving from sql express to full Sql but I have a few questions. Some of the items I fell on are: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1028601 now, a question I have is, article mentions reinstating the vcenter DB but is the db RAS (Single Sign-on) and update DB Manager, they are all have to fly over on the new server by following the same instructions? I'm sure they do, but I was wondering if special measures or the restitution order is important. Thank you

  Exactly. Add it to the MSDB. You can remove only database after the installation/upgrade.

• algorithm: show the relationships between the 2 data tables.

  I want to see '-connection path "between 2 tables given.
  Relationships of sample table:
  
  1 table a (ID)
  2. table B (ID A_ID), column "A_ID" has forced foreign key pointing to the column "A.ID.
  3. table C (ID, B_ID), points of 'B_ID' of column to column B in the table identifier.
  
  Entries in the algorithm: 'A' and 'C '.
  Outputs of the algorithm:
  ' (1) ' has '-of > 'B '->' C '.
  
  So put shorty that I give two strings as input to table names and identify those unique 2 lines in the table "user_tables. Now, these 2 tables have constraints of foreign keys pointing to some other tables in the database and possibly go through these pointers, so that we can draw 'A-> B-> C'. The relationship is defined somehow wuth series of paintings:
  USER_CONSTRAINTS
  USER_CONS_COLUMNS.
  
  How can I write this request carefully to see if 2 tales given have a relationship and how this relationship looks like, maybe there is way-table "B" or maybe C just of points in A.
