• Columns of type OBJECT: how to store as SECUREFICHIERS

  I have a large table with a column of OBJECT type, each of which contains a good amount of data. It would be very compressible, if only it was stored as a navigation. Is there a way to specify that the LOB that Oracle uses to implement objects are stored as a navigation?
  
  Thank you

  Hi Gary,.

  You can set the parameter db_securefile, to enforce using securefile.
  You can also consider moving the lob to a compressed lob or dédupliquée.

• How to create a table with editable column values.

  Hello world
  I think it's very simple, but I am unable to find how to do this. This is my requirement. I need to create a table with n columns and 1 line initially. the user must be able to enter data into this table and click of a button must insert the data into the database table. Also, there should be a button at the bottom of the table to add 1 line to the table.
  
  I know how to do the insertion of data, but can someone please let me know how to create a table which allows the user to enter data and how to create a line button Add 1?
  
  
  Thanks in advance!

  Raghu,

  Go through the tutorial of Toolbox Page & Advanced section of the Guide of the OFA table.

  Step 1 - you need to create EO & VO from this EO. This EO will be table of database where you want to insert the data.

  Step 2 - create an advanced table region. (See this section in table advanced for more details)

  Step 3 - attach this VO in the BC4J region advanced Table component.

  Hi Ram,

  You must first set the out parameters as follows:
  ((OracleCallableStatement) oraCall) .registerOutParameter (5, OracleTypes.VARCHAR, 0, 10);

  Then execute the callable statement. After that, you can get the value as
  String value = oraCall.getString (5);

  Hope that helps.

• With CVI SQL Toolkit, how to add the new variable param column in a table.

  Dear all:

  I used the CVI Sql toolkit to create a database, but now I don't know how to add a new column to a table in variable param.

  I know, to add a column with the name of constant column could be down by below:

  DBImmediateSQL ((hdbc, "alter table table1 add column1 char [100]");

  But if Column1 is a param variablae how can I write the code? Please advise?  It will be appreciated if you could give me an example.

  Best regards!

  HI -.

  If you look at the parameters that you pass to the SQL function, you can see that the second parameter is a string constant. In your code, you can create an array of characters (string). You can then use sprintf to programmatically determine what will be the contents of this variable. In the function call, you can put the variable instead of the literal string, and you will have a customizable SQL statement.

  Hope this helps-

• How to create the Table using the column Drag and Drop feature

  Hello:
  I'm new to Data Modeler tool Oracle SQL dev and would like to know if there is a way to create a new table by reusing existing columns or groups of columns. The idea is to maintain consistency and save time of table design. If the columns created previously can be reused and require, drag and drop column in the right pane, then only new columns must be created manually.
  
  Any thoughts on this will be appreciated.
  
  Thank you!

  Yes - just change the name of the model table in the script (t_name = "table_template") then save this new transformation for later use.

  I don't know how to apply only some of the tables. Seems like something you could do to a secondary view level?

  Perhaps someone else on the forum can advise how to change the script to work on a subview only instead of the whole model.

  Hello

  U go.

  1 the interface:

  "Put a filter in your 1 on attr.name = array ' PRODUCT_CODE.

  In the map target TABLE2
  SERVICE_ID = TABLE1. SERVICE_ID
  PRODUCT_CODE = TABLE1. ATTR_VALUE

  Use SQL IKM append control

  Interface 2:

  "Put a filter in your 1 on attr.name = array ' PROVIDER '.

  In the map target TABLE2
  SERVICE_ID = TABLE1. SERVICE_ID
  PROVIDER = TABLE1. ATTR_VALUE

  Do SERVICE_ID as KEY (when you click the column target in properties, you can see KEY under properties of the target column) and use the incremental update of the IKM Oracle.

  PS: I assume that Oracle as the source and target.

  And you can refer to the documentation,

• How to update a table whose name column contains an ampersand?

  Hello
  
  I need to update a column whose column name contains an ampersand and cannot find a way to do it. Option is not there to have the name of the column changed.
  
  Ex:
  
  Aircraft UPDATE

  This property returns an error of missing an = sign
  
  I tried:

  does not work
  
  
  Any help is greatly appreciated.
  
  Thank you

  Not sure if you have this problem here.
  & could also has power not characters in the normal column names (didn't test).

  In this case, you will need to put the name of column ".»

  + example +.
  {code}
  Aircraft UPDATE
  The VALUE "d & f" = 1
  WHERE aircraft_code = '737';
  {code}

  Be aware that in this case the column name must be spelled exactly as if it was when the table was created.
  Included case.

  {code}
  Aircraft UPDATE
  THE "D & F" VALUE = 1
  WHERE aircraft_code = '737';

• How to upgrade a table within a trigger

  I have a simple question.
  Suppose I have the table TAB1 with fields F1 and F2 and I created the following trigger;

  for each line
  declare
  
  Tab1 v_F2. % Of F2 type;

  ORA-06512: at "INSERT_TAB1", line 47

• How to store values of TextField in table

  Hello

  I am trying to write a code to store values of TextField in a table. I know how to convert entire TextField. But after that, we have different integer variables. I can't understand how to store values of these whole different variables in a table by using a loop.

  public class ArrAvg {}

  Public Shared Sub main (String [] args) {}

  int arr [10] = new int [10];

  inputNumbers (arr);

  }

  void int inputNumbers (int arr [10]) {}

  int i;

  TextField field1 = new JTextField();

  TextField Field2 = new JTextField();

  Field3 TextField = new JTextField();

  String value1 = field1.getText ();

  String value2 = field2.getText ();

  String value3 = field3.getText ();

  val1 = Integer.parseInt (value1);

  val2 = Integer.parseInt (value2);

  val3 = Integer.parseInt (value3);

  for (i = 0; i < 10; ++ I) {}

  arr [i] = val1 (this should be replaced by val2 and after that by val3? I don't know how to do this)

  }

  }

  Some body please guide me.

  I have stored text field in ArrayList so i should traverse the ArrayList. But when i am converting the contents of Arraylist into integer, i am getting type mismatch despite the fact that my ArrayList is of String type.
  
  
  

  Yes - the ArrayList to string but you create an iterator for object

  Iterator itr = al.iterator (); getting iterator of arraylist to iterate through the items

  This method of "al.iterator" () returns the iterator; for your use case E-online String. See the API

  https://docs.Oracle.com/javase/8/docs/API/Java/util/ArrayList.html

  You set it to 'Iterator' which is NOT a generic, so only objects are returned.

  So get back to string.

  Create your instance of the iterator Iterator.

  Is it possible to avoid "iterator"?

  Why avoid it? Just use the appropriate iterator.

  The class has a 'size' and a method 'get (int index) '. So you can use a loop from zero to the 'size', but simply use the iterator.

• How to represent Nested table as variable/object in OIC

  Hi all
  
  I'm new to the BEAK.
  
  I now have the nested in my database table.
  Nested table:
  Create the type type1 as an object (name varchar2 (20));
  Create the type type2 as type1 table;
  create table table1 (varchar2 (20) col1, col2 type2) store col2 table nested as table2;
  
  Can someone help me to col2 as C structure/typedef to use it with OCIDefineObject?

  You can take a look at Chapter 11 of the Guide to the programmer of the OIC. Look at the Collections inside section. You can represent the nested as OCITable table *. In addition, you can generate a representation of the structure of your object using OTT type. Please let us know if that answers your question. In the case where you are not able to proceed please let us know.
