• Comment of tables and columns are included in the Data Modeler

  Hi all
  I used Oracle SQL Developer Data Modeler (Version 3.0.0.665) and created a data model for my project. I sent an email a PDF version of the data model to our systems analyst. She asked if I could re - create the data model and include table and column comments. Is this possible and if so how this work is it?
  
  Thank you for your comments,
  
  Seyed

  Seyed salvation,

  I used the Data Modeler and create a report. The report included 36 .csv files

  What is the purpose of this 'report' task, because 36 files csv does not sound like report to me. Watch "files > reports" feature - you can generate reports for your model. -for any model, single table or tables belonging to specific subview. The report of the complete table contains additional details, so if you need these comments, then only you can create a template and select column comments appear only. So some general information table will be also included.

• Tables and lists are necessary!

  I really like to use the Muse and it's perfect for simple sites. However, even simple sites must:

  Feature	Reason
  Tables	Because sometimes a list of items must be presented in a table (list of classes to think or a school play - they are tabulated in the real world. Why not to muse? There are reasons to use tables that are not trained in the old way of online content available! It's silly that the Muse team cannot understand this!
  Lists	It is a natural part of the web. It's a shame that it has been ignored for years Can't understand why Muse build this! We arrived at the Moon - why we cannot build lists?

  EverNote, Onenote, Dreamweaver, Word... even this forum supports the two concepts... why not Muse?

  Support to the lists is 20141.

  Support of tables is not there yet.

• Tables and frames, are that they still a good idea to use in design

  What I know about SEO that they are not really a good idea.

  They seem to be able to be done in css, so is the best way to go...?

  Aren't good ideas, especially executives.

  Mainly, minimal tables used for data forms perhaps.

  If you can do without, so it is best to do. If you must use then do so, but in moderation.

• All tables and xml are be NULL problem

  Hello guys

  I'm working on a project that uses the format of loading xml, e4x and intensively, table manipulation and it was fine but now I'm stuck on a strange problem.  All code was beautiful and application work and respond in a desired way, but then mystourisly it stopped working and started to return NULL values in almost all the tables of the (internal) actionscript and XML varibales.
  
  Now every time I have to load the xml file and set the loaded xml internal variables, internal values get only NULL instead of data.
  The same is the situation with the berries, I created a few components in mxml, and when I passed them to reference tables, the code gets compiled successfully, but again Array has only null values [that code worked very well too]

• Why mandatory columns of the Base tables and interface are different?

  Hi guys, I support provider in PA (ap_suppliers) thanks to the Interface table (ap_suppliers_int), but my confusion is that ap_suppliers have 8 required columns, but its interface ap_suppliers_int have only 2 column.why? mandatory and also with these 2 columns also load records.
  
  Kind regards
  Shakeel khan

  Yes sometimes it is and also depends on the current configuration of oracle. Some of the fields are automatically generated.

  sometimes better to analyze the package to interface and then use the interface programs.

  Thank you

• SubVis computer - which is compiled by calling Vi and who are not

  I have a request in which a compiled exe dynamically load a Subvi (sub-VI-A).

  The Subvi then statically calls a Subvi (sub-VI-B) who calls statically another Subvi (sub-VI-C)...

  All the SubVis are part of a source distribution is copied on the remote computer with the executable file.

  If I change the Sub-VI-A or sub-VI-B on the remote machine, I see these changes when sub-VI-A is called.

  However, the changes in the Sub-VI-C (on the remote machine) are never seen when sub-VI-A, B... are executed.

  In fact, I can delete sub-VI-C on the remote computer without any problem.

  However, if I delete sub-VI-B, sub-VI-A raise an error because it cannot find slot-VI-B.

  I'm completely confused.   Why is sub-VI-C compiled in sub-VI-B, but sub-VI-B is not compiled into the Sub-VI-A?

  Sub-VI-C is also used within the executable itself?

• Dimension to build using the SQL table and process to populate the SQL table

  I have a dimension in a cube that is manually* built by one of our power users. Now, I have to get all the information of members of this dimension in a SQL table (example: with columns... Level0, level0property, level1, level1property etc...) to use this table in the STUDIO for the responsibility of the Member.
  
  Is there any easy process to do this? Currently I am building each line manually in the SQL table and there are 1100 + members in that manually built dimension. Please advice.

• Creating a unique index frame on a one-to-many table and search

  Hello
  
  I was properly put in place of the full text index on multiple columns on the same table (using the MULTI_COLUMN_DATASTORE preferences), but now I have a situation with a table of one-to-many data collection (with a CF of a lookup table), and I need to get columns through two of these tables. Code example below, several of my chatter after the code block:
  

  CREATE TABLE SUBMISSION
  ( SUBMISSION_ID             NUMBER(10)          NOT NULL,
    SUBMISSION_NAME           VARCHAR2(100)       NOT NULL
  );
   
  CREATE TABLE ADVISOR_TYPE
  ( ADVISOR_TYPE_ID           NUMBER(10)          NOT NULL,
    ADVISOR_TYPE_NAME         VARCHAR2(50)        NOT NULL
  );
    
  CREATE TABLE SUBMISSION_ADVISORS
  ( SUBMISSION_ADVISORS_ID    NUMBER(10)          NOT NULL,
    SUBMISSION_ID             NUMBER(10)          NOT NULL,
    ADVISOR_TYPE_ID           NUMBER(10)          NOT NULL,
    FIRST_NAME                VARCHAR(50)         NULL,
    LAST_NAME                 VARCHAR(50)         NULL,
    SUFFIX                    VARCHAR(20)         NULL
  );
  
  INSERT INTO SUBMISSION (SUBMISSION_ID, SUBMISSION_NAME) VALUES (1, 'Some Research Paper');
  INSERT INTO SUBMISSION (SUBMISSION_ID, SUBMISSION_NAME) VALUES (2, 'Thesis on 17th Century Weather Patterns');

  INSERT INTO ADVISOR_TYPE (ADVISOR_TYPE_ID, ADVISOR_TYPE_NAME) VALUES (1, 'Department Chair');
  INSERT INTO ADVISOR_TYPE (ADVISOR_TYPE_ID, ADVISOR_TYPE_NAME) VALUES (2, 'Department Co-Chair');
  INSERT INTO ADVISOR_TYPE (ADVISOR_TYPE_ID, ADVISOR_TYPE_NAME) VALUES (3, 'Professor');
  INSERT INTO ADVISOR_TYPE (ADVISOR_TYPE_ID, ADVISOR_TYPE_NAME) VALUES (4, 'Associate Professor');
  INSERT INTO ADVISOR_TYPE (ADVISOR_TYPE_ID, ADVISOR_TYPE_NAME) VALUES (5, 'Scientist');
  
  INSERT INTO SUBMISSION_ADVISORS (SUBMISSION_ADVISORS_ID, SUBMISSION_ID, ADVISOR_TYPE_ID, FIRST_NAME, LAST_NAME, SUFFIX) VALUES (1,1,2,'John', 'Doe', 'PhD');
  INSERT INTO SUBMISSION_ADVISORS (SUBMISSION_ADVISORS_ID, SUBMISSION_ID, ADVISOR_TYPE_ID, FIRST_NAME, LAST_NAME, SUFFIX) VALUES (2,1,2,'Jane', 'Doe', 'PhD');

  COMMIT;

  I want to be able to create a text index to group these fields:
  
  SUBMISSION_ADVISORS. FIRST NAME
  SUBMISSION_ADVISORS. LAST_NAME
  SUBMISSION_ADVISORS. SUFFIX
  ADVISOR_TYPE. ADVISOR_TYPE_NAME
  
  I looked at DETAIL_DATASTORE and USER_DATASTORE, but examples of Oracle Docs for DETAIL_DATASTORE leave me a little confused. It seems that this should be fairly simple.
  
  Ideally, I try to avoid creating new columns and keeping a minimum shutter adjustments. But I'm open to any suggestion. Thanks for your time and your thoughts.
  
  -Jamie

  I would create a procedure that creates a virtual with labels document, what is the multi_column_datatstore behind the scenes. Then I would like to use this procedure in a user_datastore, so the result is the same for several tables as a multi_column_datastore for a table. I would use auto_section_group or another type of Group of sections, so that you can search from WITHIN as with the multi_column_datastore. Please see the demo below.

• partion tables and indexes

  Hi all
  
  DB: 10.2.0.4
  
  Is that we can convert a normal table into partitioned tables?
  If Yes, then what is the existing indexes on this table?
  
  IM totally new about partitioning (Table and Index). I read the oracle docs but still have confusion with local and global index (score and no-partion)...
  
  
  Please suggest...
  
  Kind regards.

  >

  >
  You can use the EXCHANGE PARTITION to do. See this article from the Oracle base
  Partitioning of an existing Table using the EXCHANGE PARTITION
  http://www.Oracle-base.com/articles/Misc/partitioning-an-existing-table-using-Exchange-partition.php

  Or you can use for DBMS_REDEFINITION do directly

  See this article from the Oracle base
  http://www.Oracle-base.com/articles/Misc/partitioning-an-existing-table.php

  You can also create a new table and INSERT the data from the old table.

  The option you are using could depend on indexes how you have, if you intend to keep them all and if the indexes on the partitioned table must be either local or global.

  To refine the new partitioned table, you really need evaluate each index to determine that the index should be global or local, and if the index should also be partitioned.

  There isn't any point to create a new table with the same indexes if you want to redefine all the indexes. You would be better of the backup of the original and then table drop indexes before conversion.

  See the VLDB and partitioning Guide

• New tables and indexes created do not appear in the view dba_segments

  Hi all
  
  I created 3 tables and indexes, but these items do not appear in dba_segments views. Is this a normal behavior? Previously, with dictionary managed tablespace, I can specify the least possible to create, at the table/index is created. But I don't know how works the locally managed tablespace. Please do advice. Thank you much in advance.
  
  I am using Oracle 11 g R2 (11.2.0.1.0) for Microsoft Windows (x 64), running on Windows 7.
  
  To reproduce this problem, I created the tablespaces as follows:
  
  CREATE TABLESPACE CUST_DATA
  DATAFILE ' d:\app\asus\oradata\orcl11gr2\CUST_DATA01. DBF' SIZE 512K
  AUTOEXTEND ON NEXT MAXSIZE 2000 K 256K
  MANAGEMENT UNIFORM LOCAL 256K SIZE MEASURE
  SEGMENT SPACE MANAGEMENT AUTO;
  
  CREATE TABLESPACE CUST_INDX
  DATAFILE ' d:\app\asus\oradata\orcl11gr2\CUST_INDX. DBF' SIZE 256K
  AUTOEXTEND ON NEXT MAXSIZE 2000 K 128K
  MANAGEMENT UNIFORM LOCAL 128K SIZE MEASURE
  SEGMENT SPACE MANAGEMENT AUTO;
  
  CREATE TABLE CUSTOMER_MASTER (CUST_ID VARCHAR2 (10))
  CUST_NAME VARCHAR2 (30),
  E-MAIL VARCHAR2 (30),
  DATE OF BIRTH,
  ADD_TYPE CHAR (2) CONSTRAINT CK_ADD_TYPE CHECK (ADD_TYPE ("B1", "B2", "H1", "H2")),
  CRE_USER VARCHAR2 (5) DEFAULT USER,.
  CRE_TIME TIMESTAMP (3) DEFAULT SYSTIMESTAMP.
  MOD_USER VARCHAR2 (5).
  MOD_TIME TIMESTAMP (3),
  CONSTRAINT PK_CUSTOMER_MASTER PRIMARY KEY (CUST_ID) USING INDEX TABLESPACE CUST_INDX)
  TABLESPACE CUST_DATA;
  
  SQL > SELECT TABLE_NAME, nom_tablespace
  USER_TABLES 2
  3 WHERE TABLE_NAME LIKE '% CUST. "
  
  TABLE_NAME, TABLESPACE_NAME
  ------------------------------ ------------------------------
  CUSTOMER_MASTER CUST_DATA
  
  SQL > SELECT INDEX_NAME, nom_tablespace
  2 FROM USER_INDEXES
  3 WHERE TABLE_NAME LIKE '% CUST. "
  
  INDEX_NAME TABLESPACE_NAME
  ------------------------------ ------------------------------
  PK_CUSTOMER_MASTER CUST_INDX
  
  
  SQL > SELECT nom_segment, SEGMENT_TYPE, nom_tablespace, BYTES
  2 FROM WHERE USER_SEGMENTS;
  
  no selected line

  An extension to what Sybrand said:

  There is a parameter called differed_segment_creation, who runs the behavior.

  If it is set to TRUE (the default), no segments will be allocated until you fill your table / index.

  Try to insert a row. You will see your table and index in dba_segments.

  See for more information

• Partitioned Tables and indexes

  Hello
  
  
  I have a question on the table and index partitioning. My scenario is:
  
  Charge 2 mio records in table T once a month. Loaded records are added to existing records, and once loaded data is never changed.
  At some point, I want to delete the older recordings, so I intend to this partition table.
  
  T table looks like:
  

  create table t (id       number(10) not null  constraint t_pk primary key,
                  period   number(10) not null,
                  contract number(10) not null,
                  attr     number(10) not null);
  
  create unique index t_ux1 on t(contract,period);
  
  create index t_ix2 on t(period);

  My plan is to partition T over the period, and I'm trying to read through the concepts
  http://download.Oracle.com/docs/CD/B19306_01/server.102/b14220/partconc.htm#g471747
  
  
  My question is now, how to manage the indexes, the t_pk, the t_ux1 and the t_ix2. Concepts of say,
  
  «1. If the table partitioning column is a subset of index keys, use a local index.»
  
  "2. If the index is unique, use a global index. If this is the case, you are finished. »
  
  
  So, that's how I read it
  -t_pk is unique, so this should be global
  -t_ux1 of columns is a subset, unless I have misunderstood (?), which should be local
  -index t_ix2 column is the same as the partitioning column, so it must be local
  
  Is this right, this t_ux1 should be a local partioned index, even if the period is the second column in the index?
  
  If true, what will happen when a partion fell?
  
  
  I am new in this area, so please feel the comment as you wish.
  
  
  Concerning
  Peter

  A partitioned index locally can only be defined as unique if the partition key is part of the columns in the index. Imagine what the database would have to do if this is not the case: in order to verify if a newly added or updated value violates the uniqueness, it will have to travel all the partitions in a serialized operation - means that no one else could do the same thing at the same time. Since he is a killer of serious scalability in terms of locking and contention, this is not allowed.

  So: Your T_UX1 index can be defined as a unique index that is local because it contains the partition key. Although the index is not prefixed ("Prefix" means that it is divided by the left side of the columns in the index) which means that there may be access patterns where all partitions should be scanned or the optimizer cannot use a method of size of effective partition according to the way the index is reached.

  Your T_PK index cannot be set as local because it must be unique (you can not use a local non-unique index in this case), but does not contain your partition key. It must be a global index. An overall index can be partitioned as well (different from the underlying table) but it doesn't have to be.

  Depends on how you access your data you have not T_IX2 index when partitioning by this key because it corresponds to the partition key and therefore could not actually be used by the mechanism of partition pruning that limit your query to the scores of individuals.

  If you have more than one MAS environment where running queries are used longer, you should be fine with the index the in general (because they could be analyzed in parallel in parallel operations), but if you have an OLTP environment, then you should avoid local no prefix indexes due to the potential problem that you need to analyze all partitions.

  Be borne in mind that with partitioning adds an important layer of complexity to other areas: in particular the options available to the optimizer and analyze cost optimizer statistics. Depends on how you access your statistical data must be maintained on several levels now (level of score and at the global level, in the case of subpartitioning may be still at this level). If your data is important and you rely on "global" level statistics (these are always the case when the optimizer at the time analysis cannot limit access to a single partition) then in the pre - 11 g databases analyze these "global" level statistics can take a lot of time and resources, since actually , you need data several times (once for the partition and even global level).

  Presenting this partitioning may mean other potential problems in terms of execution that change (not for the better sometimes) plans and how to effectively collect statistics. Note that g 11 addresses the issue of 'statistics' by introducing the so-called "extra" global statistics. Greg Rahn wrote a [blog note | http://structureddata.org/2008/07/16/oracle-11g-incremental-global-statistics-on-partitioned-tables/] on this nice feature.

  >

  If true, what will happen when a partion fell?

  Since you're already on 10g, you can specify the database to update the scores of the local index using the UPDATE of the INDEX clause, while 9i could maintain only an overall index and it is up to you to rebuild the local index partitions after the partition DDL on the table (according to the DDL operation).

• How FLASHBACK all TABLEs and indexes in a certain pattern for a restoration of p?

  Today I read a few web pages on how to use FLASHBACK to restore to a Restore Point.
  
  Unfortunately, all of these examples show just how to restore a single TABLE for example
  
  FLASHBACK TABLE t to RESTORE POINT before_we_do_anything;
  
  But how can I FLASHBACK all TABLEs (and indexes and other dependent objects) in a certain pattern to a one-step restore point)?
  
  FLASHBACK myschema.* to before_we_do_anything POINT of RESTORATION;
  
  does not work.
  
  Peter

  There is nothing like that. However, you could flashback the entire database to a point in time. It would of course have implications through patterns all the good.

• Easy to change the owner of the TABLE (and according to indexes and views) available?

  I want to change the Owver from a TABLE (and the owner of all VIEWS and INDEXES in function).
  The only way that I know so far is something like
  
  CREATE TABLE < newschema >. < table_name > select * from < oldschema >. < tablename >;
  
  Then, slide old TABLE
  Recreate it possible all the CLUES and the views.
  
  It is kind of bulky.
  Especially when I don't know what indexes exist for a certain TABLE.
  When I investigate this and I have found 4 indexes so much work needs to be done.
  
  Is there a shorter, smarter way to accomplish the task.
  I prefer a SINGLE task of all-for-statement
  
  :-)
  
  Thank you

• What is the difference between a table and a subform?

  What is the difference between a table and a subform in LC forms? Please post your answers about the merits and demerits of using subforms instead of tables.

  Hello

  a table is simply a set of subforms with a particular role.

  It is easier to handle the tables if they must be dynamic (add or remove lines, show or hide lines when page breaks appear etc..).

  And Designers UI has some dialogue prepared in the object palette to simplify the settings of the tables.

  For subforms, dialog boxes are more frequent, so you have yourself a little more script.

  But at least you can do everything with subforms as you can do with tables.

  The only one who is not very good with tables we work when you wrap arrays in other tables.
