• 6 random numbers without repetition

  I'm doing a generator of 6 random numbers between 1 and 48. When the user clicks a button randomly 6 numbers appear in 6 different textFeilds. The problem is that I don't want the same number twice. How can I generate 6 different random numbers without using back and out of the service?

  import flash.events.Event;

  Stop();

  btn.addEventListener (MouseEvent.CLICK, random1);

  function random1 {(evt:Event)}

  display1. Text = "";

  Display2.text = "";

  Display3.text = "";

  display4. Text = "";

  display5. Text = "";

  display6. Text = "";

  var r1 = Math.floor (Math.random () *(1+48-1)) + 1;

  var r2 = Math.floor (Math.random () *(1+48-1)) + 1;

  var A3 = Math.floor (Math.random () *(1+48-1)) + 1;

  var r4 = Math.floor (Math.random () *(1+48-1)) + 1;

  Take the first six of the mixed table

  var list: Array = nums.splice (0.6);

  assign values to the textfields

  for (var j: uint = 1; j<=6;>

• Add values for them to table without accidental

  Hi I am writing a program for research at penn state behrend. It is designed to take a pressure transducer values and calculate pressure losses. My teacher wants to gather incriments of 10, their average values and then store all means when the user chooses you to start saving. I use a loop for to bring values and the average of the 10 output collected values in a table. After 10 averages are collected the program to output these values in a table. I can't understand how to continue to add to this table without overwriting the previous values. Any help would be appreciated. I'm uploading what I have so far. Thank you

  In the code the first comment is wrong in fact, I think, this one:
  "There is no table built in oracle, you must declare your own."
  I remember there are some types of collection of the system, if I not mix with something, I remember there was a sort of like they were undocumented, so we can say legally that the comment in the code has always been right.

• Potential problems for tables without primary keys and unique keys

  GoldenGate 11.2.1.0.3/Solaris 10
  DB: Oracle for Oracle (Source and target is 11.2.0.3)
  Topology: unidirectional
  
  
  In our one-way configuration GG, little of the tables being replicated is not a primary key or a Unique key.
  
  Last week when we have implemented GG for the test, we received warnings for these table below.
  

  GGSCI > add trandata WMHS_UD.crtn_dtl
  
  2013-01-12 11:34:33  WARNING OGG-00869  No unique key is defined for table 'CRTN_DTL'. All viable columns will be used to represent the key, but may not guarantee uniqueness.  KEYCOLS may be used to define the key.
  
  Logging of supplemental redo data enabled for table WMHS_UD.crtn_dtl.

  Replication seems to work very well for these tables.
  
  Googling, I think that there may be performance degradation when you replicate tables without PK or the United Kingdom.
  
  But are there other potential problems such as data of a certain kind not replicated to the lack of PK/UK?

  It really depends on the data.

  By default, GG is combining all columns as a virtual primary key but don't no conflict control by default. So when you can be sure that the record you insert into the table is unique, then it will work.
  BUT as soon as you insert the same record, which is already inserted, then you will encounter problems.

  Let me show what happens when you use an initial charge because it makes it easier to describe:
  We start at 10:00 the capture for a table. Now, you insert a record at 10:00 in the tables. When you now start an initial charge to 10.02, then check you have inserted in the database to 10.01 will be repeated two times. During the IPL as the initial charge is made to 10.02 and it includes data of 10.01 AND it will be replicated again through the process of capture/replicate.

• You would design Tables without primary key?

  If you were asked to design a schema, if you create a table (however irrelevant) without a primary key? For example, a 'unprofessional' table such as a logging of errors table that records exceptions thrown from stored procedures, create you this table without a primary key?

  In a relational database you define und work with entities (tables) and you put in relationship to each other by joins. An entity must by definition always be identified by a unique key.
  If you don't know what kind of unique key identifies your entries in the table, it is almost certain that working from home in your datamodel and table designs had not been made. Your database objects contain tables, and they must have a unique identifier. Often it is a primary key (PK) composed of several columns.

  By definition a datamodel that contains the tables without primary keys is nomore a relational datamodel and one of the fundamental bases for the creation of a relational database is violated.

  Frankly I do not understand why Oracle allows the tables without primary key. Another system such as SAP R/3 are more stringent. Primary keys are required in the SAP and believe, when starting, it is sometimes tedious to define the primary key structures, but it's the basis of designing together relational datamodel you will put in place. You now SAP is based often on a DB ORACLE layer. They could do it, and these "extend" their functionality. But they are smart guys in Walldorf, and they always refrained to do. It's a good guess to believe, they have a good reason for it.

  Tables without primary key are NO relational tables, they are dungpiles. As Oracle needs priimary key itself in order to operate a relational database, ROWID have been defined. ROWID is the primary keys of the tables where the customer does not have a PK. But nice as ORACLE is, they strongly recommend not to use these ROWID in the application or database layer. ROWID is no identifier object that are stable in time and space (eg. two different databases in a distributed design oder a DEV and PROD-system).

  Definition of PK implies certain rules for the programming of your application and your DML operations. Especially you often MERGE in a relational table instead of simply INSERT'ing piece in a dungpile.

  When it later on with SELECT large datavolumes dataaccess, again the differences between well-defined joins (all based on the PK-relations) and joins non-unique keys will be the order of magnitude. Not only that, the latest degrades in performance much more quickly with the growth of result sets. When you start fumbling with no UNIQUE INDEXES, speed up performance in the operations of dungpiling you are already closer to hell than on a sunny day in the world of relational data.

• Truncate a table without removing the redo log

  Hi Experts,
  
  Could you please tell me is it possible to truncate a table without removing the Redo log. In fact, I know it is not possible, but some body asked me the same question, and I want to be sure before answering him.
  
  Help, please.

  You can restore data from a backup or export.

  You cannot use FLASHBACK to recover the data unless you use GR 11, 2 and that you have prepared (using TOTAL RECALL) for this in advance.

• &lt; af:table &gt; without a scroll bar?

  jDev Version: 11.1.1.13.0
  
  Is it possible to display a < af:table > without a scroll bar?
  My requirement is to display the rows of the table such that all lines should be displayed but no scroll bar. The height of the table should expand automatically when the number of lines increases. In my case the table shows a scroll bar.
  I'm keeping the element of array inside a < af:panelGroupLayout layout = "vertical" >
  
  Any help much appreciated...

  Definition of the attribute autoHeightRows on your table will make the Extensible table according to the number of rows you enter (the value can be derived through EL). Note that you must set contentDelivery immediate on the table, too.

• Add a simple table without one logical join to another table (OBIEE 10 g)

  Sometimes I want to just show a simple table without a logical join to another table in the repository. However, every time I move the layer Business model and mapping and an audit of overall coherence, he tells me that he has a logical join and I am forced to create another table to join her. Creating a dimension-fact relationship. There are times where I need this relationship and I want to just display some data. Is anyway to circumvent this?
  
  Thanks in advance!

  Yes, you must create a join. You can't take one table to MDB layer. You can create an alias for the table. Join this alias and the base through any common column table and take the two tables in MDB and table you want to the presentation layer.

  Another way is to create a view in the physical layer. Write a select statement as

  Select Table primary_key

  Where primary_key is the primary key of the base table. Join the base table of view ith and repeat the steps defined for the Alias.

  Kind regards

• Insert values into a table from another table without duplicates

  Hello
  
  I have a table with a field called ID; This field has duplicate values of ID.
  
  Then I have an empty table B (with the same fields of the table A) and I want to insert the values of the ID (on the table) without duplicates.
  
  Can you help me?
  
  
  Thank you much in advance.

  Hello

  If your table has duplicate values, then you cannot add a UNIQUE constraint. In this case, you will need to use a roundabout way or remove duplicates before imposing the constraint. Hope it answers your question.

  see you soon

  Two standard methods to compare the tables are either to use DEFINED such as UNION, UNION operations or LESS.
  Or use a FULL OUTER JOIN.

  If the structure of the table is the same and that you want to compare all the columns, then set them operators are the best way.

  If you want to compare only on one or more columns and want to see the other columns, then a FULL OUTER JOIN is the best way.

  Here is an example

  select A1, A2,
        count(distinct sourcetable) cnt_tables,
        count(sourcetable) cnt_records,
        count(case when sourcetable = 'A'  then 1 end) record_is_in_A,
        count(case when sourcetable = 'B1'  then 1 end) record_is_in_B1,
        count(case when sourcetable = 'B2'  then 1 end) record_is_in_B2
     (select 'A' sourceTable, a.* from tableA a
      union all
      select 'B1' sourceTable, b1.* from tableB1 b1
      union all
      select 'B2' sourceTable, b2.* from tableB2 b2
     )
  group by A1, A2
  having  count(distinct sourcetable) < count(sourcetable) ;
  

  It is an example. It will show you the records that have duplicate data in the following tables.
  If you want to display all records that are in A but not in B1, you can add a few other checks.
