Sequence of triggers

• SDDM 4.10.866 - sequences and triggers

  Is the automatic creation of triggers and known to operate in 4.10.866 sequences.

  Logic model has an ID.

  I have templates for relaxation and sequence set at the level of physics/preferences/Oracle.

  Model relational column is set to global autoincrement.

  I have no name of sequence or a trigger generated

  When I add a physical model, I don't see any sequences or triggers generated.

  Simon

  Ah ok.

  I thought that the physical model would be the lower level representation of what would be generated automatically as the DDL output.

  I generated successfully all the required sequences and triggers by changing the relational model.

  Thanks for your help.

• Sequences and triggers

  I feel terribly stupid, that I can't fight another beginner problem, I can't find anywhere with the right information.
  
  I want to create a sequence that is the primary key of a table, which starts at 1 and increments by 1. Whenever I insert a line in the table I want it to trigger this sequence in the primary key. IE, I want to insert the names of film, and I want the number of films for the PK. (I.e. count of 1 foot per film).
  
  I think you'd need a sequence and a trigger. The sequence defined as the primary key when you create the table.
  I did all that. Creates a Table with the primary key of the sequence I created before hand. Then, I tried to create a trigger to trigger before each insertion.
  
  Here's the SQL code of the sequence
  

   CREATE SEQUENCE   "MOVIE_NUMBER"  MINVALUE 1 MAXVALUE 200 INCREMENT BY 1 START WITH 9 NOCACHE  NOORDER  NOCYCLE

  And here is the SQL code for my trigger
  

  CREATE OR REPLACE TRIGGER  "BI_MOVIES" 
    before insert on "MOVIES"               
    for each row  
  begin   
      select "MOVIE_NUMBER".nextval into :NEW."MOVIE_NUMBER" from dual;  
  end; 

  Here is my SQL Table
  

  CREATE TABLE  "MOVIES" 
     (     "MOVIE_NUMBER" NUMBER(28,100) NOT NULL ENABLE, 
       "QUALITY" VARCHAR2(10), 
       "PRODUCER" VARCHAR2(80), 
       "YEAR_PRODUCED" NUMBER(1,5), 
       "DESCRIPTION" VARCHAR2(4000), 
        CONSTRAINT "MOVIES_PK" PRIMARY KEY ("MOVIE_NUMBER") ENABLE
     )
  /
  
  
  CREATE OR REPLACE TRIGGER  "BI_MOVIES" 
    before insert on "MOVIES"               
    for each row  
  begin   
      select "MOVIE_NUMBER".nextval into :NEW."MOVIE_NUMBER" from dual;  
  end; 

  If I enter a figure in the primary key 'MOVIE_NUMBER' (via the GUI APEX object browser), then it gives me

  error ORA-01438: value larger than specified precision allowed for this column

  If I enter any number in "MOVIE_NUMBER", then I get

  error ORA-06502: PL/SQL: numeric or value error: number precision too large ORA-06512: at "MOVIE_LIST.BI_MOVIES", line 2 ORA-04088: error during execution of trigger 'MOVIE_LIST.BI_MOVIES'

  MOVIE_NUMBER data type is NUMBER (28,100), so I have trouble that it is larger than the specified accuracy? I don't know what's happening or why it doesn't work.
  Any help would be greatly appreciated.
  
  Thank you
  Tom

  If it's just a primary key, make a number and do not give a clarification. A sequence is just a unique number and if its your PK you don't care really what number.

  If movie_number is a unique identifier, create a unique constraint on this column with any precision you need.

• What is the outbreak of shooting sequence in the following example?

  Hai,

  If we have a table with the name 'XXSample '.
  

  Now let's write triggers on the table as follows

  "before the table insert level".

  "before the level of line insertion.
  

  "after the table insert level".

  'after insert row level.

  What is the sequence of triggers... What trigger fires in the order means.

  Its documented triggers

  Execution is like that.

  1. before the insert statement level

  2. before the level of line insertion

  3. after the level of line insertion

  4. after the insert statement level

• Sequence of keys generated by their Summit

  Thank you

  Hello

  Ok.
  If you create form by using Wizard of the Apex, the step where you set the source for the primary key columns,
  you select the existing sequence. So, you see a sample how to do it.
  Apex will generate an additional process that populate the primary key of the sequence

• Reinstall XP Media mouse stops working then install

  Hi all, hope someone can help!

  I reinstall XP and I get a dialog box for my Audio Driver, but my mouse and keyboard stop working so I can't click the boxes to continue the installation? any ideas?

  Thank you

  Brook

  How do you reinstall your system?  You boot from a DVD or you press a key at the beginning of the boot sequence that triggers an install from a recovery partition?  If you use a recovery partition, maybe this partition is corrupted as well (disk crash?).  In this case, drag the backup DVD that you did when you got your machine and try to start those.  Usually a part of a resettlement total of causes Windows reformatting the hard drive. If get you there, choose the full format, not the "quick" format

  If you think you may have hardware problems, you can try to use another machine to create Linux Livecd such as Knoppix orUbuntu , and boot from that (use the 'Try Me' mode if Ubuntu).  If you have hardware problems, then the start of these CDs would probably fail as well.

• Feature line with key oracle.jbo.key is not found

  I've seen similar issues posted here but no go in enough detail to help me solve the problem I have just started using Oracle ADF a few hours ago.

  I have connected to our oracle successfully database and set up the display of an entity based on a base table which seems to have worked very well. When I run AppModule I see all the fields of the fine table, but when I change a content of columns to a valid value, and then click validation I get this error: "line entity with key oracle.jbo.key [all fields in table] is not found in the table" even though I don't know why, because it is without a doubt.

  The base table is a table of configuration when a new record is added manually a sequence is triggered to autopopulate the column id of the table. I read that this trigger could be the problem but I'm not sure why, as I'm only an update on an existing id, not create new ones?

  User, tell us your version of jdev, please!

  The framework must be a primary key defined on a table that you want to update. It will be weird if your doe not table a PK. define a pk in the table (if you cannot change the db, you can define the pk in the framework and try again.

• Identity columns Oracle 12 c in the entity of the ADF

  Hello

  All the PCs in my diagram have their values provided by the new identity column feature in Oracle 12 c. Previously, during backup with sequences and triggers, I would choose the DBSequence type for the attribute PK in my ADFBC entity.

  I can leave Type BigDecimal, uncheck the required box and check "Update on insert", and then the PK is filled in the DB and the entity. However, it is a desirable solution at least.

  How can I tell ADF 12.1.3 I use identity columns, so that I can undo a mistake 'attribute is required?

  User, this feature is not currently supported in 12.1.3. As you have already discovered, you can create a table in 12 c with IDENTITY and use it in ADF (g 11 or 12 c). To some extent, this works. However, you cannot define a relationship master detail using the IDENTITY as PK feature will be created in the DB only after insertion. So in the EO attribute PK remains empty until you at least have published data and refresh the attribute to get the DB assigned ID.

  For an insert master detail, this would mean that you must wait until the parent gets his id before you can set the necessary FK in detail. You can do this, but it's the work you have set yourself.

  ADF uses the DBSequence data type for this kind of work. Here a negative number is assigned to the new line of master and as FK details until the transaction is committed. Then, negative numbers are exchanged by the framework with the now valid PK and FK.

• What is the best way to move the data from the app and Server data structures?

  Hi guys,.
  
  I developed my application locally with Apex 4.2 and Oracle 11 g XE on Windows 7. Not far away, it is time to move the application to a server Oracle Apex. I guess that Exim is the way to go app. But what about the APA tables and data (tables/as 'customer' and 'account' created specially for the application)? I've been using a modeling tool, so I can run a DDL script to create the database server data structures. What is the best way to move the application data on the server? Is it possible to move the structures and data in a single process?
  
  Thank you

  There is probably another way to get here, but in Developer SQL, on the navigation tree, expand objects until your table, right-click, and then click EXPORT... you will see all the options. It is a tedious process and it sucks IMO, but yes, it works. This is zero especially because 1) it's a table at a time, 2) If your data model is robust and has constraints and sequences and triggers, then you will need to disable all for the insert and we hope you can re-enable constraints, etc. without hitch (good luck, unless you have only a handful of tables)

  I prefer to use the oracle EXP command-line to export an entire schema, then the server target, I use IMP to import the schema. In this way, it is almost true. This makes the dirty life if you develop multiple applications in a single schema, and I felt pain - however - it is much easier to drop the tables and other objects is to create them! (thus, even if the process of EXP/IMP moved more than you wanted to "move".. blow everything you don't want on the target after the fact...)

  You can use method datapump oracle too.

  If not, what can be done, IF you have access to both servers of your instance of SQL developer (or if you can tnsping both already from the command line, you can use SQL * MORE), is to run a script that will identify the objects of your applications apex (usually by the prefix for the names of objects, such as % EBA_PROJ_ etc.) and do all the manual work for you. I've created a script that does just that so that I can pass data from dev to prod servers on a dblink. It is difficult because of the order that must be executed to disable constraints and then turn it back on and of course, more complicated if don't always precede you ALL your "objects demand '... (tables, views, triggers, sequences, functions, procs, indexes, etc.)

• auto increment column

  Hello
  
  I have a total of 700 tables, each table has a column that must be incremented automatically.
  
  I am thinking to create distinct sequences and triggers for all tables.
  
  Is there a different approach that could be followed or sequence-trigger is the best option available.
  
  
  * This database has been migrated from MySQL where auto-increment option is available for columns contrary to oracle.
  
  Please notify.

  Salman Qureshi says:

  So I want to generate a trigger too.

  Still not clear what triggers have to do with the automatic generation of the column values. You will probably have to ask them about the details of trigegrs self-generation of values? If you just need automatic generation of values, sequences are what you need.

  Salman

  Using a trigger to fill the column ID with the value of the sequence, you don't have to worry about the application 'forget' to do. Some DBA or developer is once of sqlplus and forget to do. Placing him in a trigger, there is simply no way to properly fill the column in question.

• How to solve problems online datamove for 1 of 3 SQL Server 2008 migration.

  I have 3 databases SQL Server 2008 I need to migrate to Oracle 11 g 2 with data only. For all the databases that I can capture, convert and deploy the database target. I can also do this with success a data movement for 2 databases online. The third database runs for about 2 hours and gives a message that the migration completed with success, but not a single line of any of the tables invades. How to understand what failed. I see nothing in the reports with SQL Developer (3.2.20.09). To save time and since I'm only interested in the tables, indexes, and data, after capturing the model, I remove developer QL, views, procedures, functions, sequences and triggers before disguised step.

  Hello

  did you remove the views, procedures, functions, etc. of the model only convert to the database where you have the problem or did you do the same for all three database?

  Did you look at the MIGRLOG table in your repository of migration? It contain useful information?

  Impdp is not flexible about the non-table objects.
  If you want these objects to be imported, then the objects must be deleted before you run impdp.

• I did something wrong with EXPDP / IMPDP

  So I made an export of 10.2.0.1

  expdp abc/def@ghi tablespace=abc directory=data_pump_dir dumpfile=abc12192011.dmp logfile=abc12192011.log

  move the dumpfile to another machine and everything done import

  impdp abc/def@ghi directory=data_pump_dir dumpfile=abc12192011.dmp logfile=impabc12192011.log

  I thought she would incorporate everything in it... but miss me objects - VIEWS, PROCEDURES, FUNCTIONS, PACKAGES, SEQUENCES (curiously, TRIGGERS are there - most of them failed with no SEQUENCE is created), etc.
  
  My question is am I doing something wrong? If this is not the case, how to import these objects into the new machine?

  You export/import a tablespace. This tablespace contains all the views, indexes, triggers, sequences you want. So instead of tablespaces, you need to specify the patterns that you want to export, than doing the same thing in impdb too.

  You can do expdp help = y for more details on the syntax.

  schemas expdp TEST_DIR dumpfile = SCOTT directory = scott/tiger@db10g = SCOTT.dmp expdpSCOTT.log = logfile

  Impdp scott/tiger@db10g schemas is SCOTT = TEST_DIR dumpfile = SCOTT.dmp logfile directory is impdpSCOTT.log

• For the Animation play button

  I have an animation of 2 very simple state. The first State has no picture the last State for all images. I have a single button that appears at the end of the two State. I have the set button to return to the State when you click on it.

  Here's what I need to do - I need to have again (refresh) when the play button is simple click at the end state 2. Is this possible? For now, it's just lies to Virgin State 1.

  Thanks for any help.

  Here's a quick example. The buttons are outside the animation, but I don't think that this should be a problem. It was done in Flash Catalyst 5.5.

  The key is to look at a sequence of actions since the trigger button is clicked. What I did say first of all the component of the animation to goto State 1 (I have add a quick transition from State 2-> State 1). I then added another sequence that triggers the change of State to State 2.
