• How to recover the data type of a column in a table?

  Hello
  
  I want to retrieve the data type of a column in a table. At the moment I'm querying attribute 'OCI_ATTR_DATA_TYPE', but it is SQLT_CHR varchar2 and nvarchar2 data type columns. I need to make a distinction between these columns of two separate data types. Y at - it all API through which I could get the exact data type of a column, i.e. "nvarchar2?
  
  Thanks in advance.

  Hello

  It is not a very direct way to do it. What you can do is to call OCIDescribeAny on the table that you want to get information. You can then get the OCI_ATTR_CHARSET_FORM attribute for the column. If the value of the attribute that you get is SQLCS_IMPLICIT, that would mean its a varchar/char/varchar2 column regular. If you get SQLCS_NCHAR, this means that the column is NCHAR. You can get the example of it here:

  http://download.Oracle.com/docs/CD/B14117_01/AppDev.101/b10779/oci06des.htm#446491

  Just look for the section "Recovering for a Table column Datatypes".

• change the data type of a column

  Since the previous post: how to change the data type of column number to varchar2 in oracle10g
  
  Measures may be:
  create table TestTable (ColA varchar2 (5));
  Insert into TestTable values('12345');
  
  ALTER table TestTable Add (ColATemp number (5));
  setting a day of TestTable set ColATemp = ColA;
  
  ALTER table TestTable remove column ColA;
  change the column in table TestTable rename ColATemp CLC;
  
  My question is:
  If the table half million records
  
  setting a day of TestTable set ColATemp = ColA;
  
  will it be a good solution? Any performance issues? There is no index on this column.

  Sort while you do DDL, you will not be able to do any operation on the table. You the best suites you. It's a time operation, you can change the table to change the data type, but it may not work if some of the data in the table confirms no new data type of column.

  If (obj is Objetpersonnalise)

  {

  do something

  }

  or you could look at using getQualifiedClassName() or getDefinitionByName()

• How to set the date type date of work

  This is perhaps a silly question, but I can't seem to get the data type date to work for a member account. When I go to the planning application and choose an account I want to put in a date entry account, the web form seems to show that the setting of the date works for the account. I even put my account type to be saved hypothesis. For example, I expect to see the date formatted in 10/20/2009 when I enter this value in the web form under my account "Hire Date". I also checked the display options in the preferences of planning. If anyone knows if this function works even on 9.3 or 11.1?

  Hello

  Looks like you have not defined the order of evaluation of Auditors. Administration > Dimensions > evaluation order > select plan type > moving accounts to another window, apply.

• Display the data type of a column in the status bar

  Hi all

  n pl/sql developer, when I select a column in a table.

  If I clicked with the mouse on the column in the query results box, it shows me the type of data and the size of the column in the status bar

  Developer SQL does not by default,

  is there an option I can change to do the same task?

  Thank you

  No, you will need to open a popup DESC of the query to see the data types of the data returned.

• How to return the data type complex of a synchronous BPEL process

  Hi all
  I have created a synchronous BPEL process, so a partner customer link was automatically created in the project. Now the link partner of this client is to have input and output variable of type normal string where as my BPEL process finally returns a complex data type.
  In order to solve this problem, I took a processing activity and mapped the collection [variable returned by my BPEL process] to the chain of production of the customer but in this way I just get a single string to store the entire collection but I want that they separately.
  
  Can someone tell me, how to manage this scenario.
  
  Concerning
  Lokesh

  After creating the partner link and the invoke (to create the variables), change the element type of the response message to the complex type definition of your collection that appears in the XSD. You can do the same thing if you want to change the element type of the payload of the request message as well.

• How to force the data type in create table field?

  Hi all

  I need to force my table to create as follows

  Create table XYZ

  (Test varchar2 (10 CHAR)

  ...

  );

  When I run my Interface the script is

  Create table XYZ

  (Test varchar2 (10))

  ...

  );

  and the DBMS translated into

  Create table XYZ

  (Test varchar2 (10 BYTE),

  ...

  );

  I have the same problem with I$, C$, and so on.

  Best regards

  Hi all

  I fix my problem:

  In Phisical Tecnology, under ORACLE Tecnology, data TYPE, I modified the definition of VARCHAR2 in VARCHAR2(%L CHAR).

  (Before it was VARCHAR2 (%)).

• How to handle the data type DECIMAL MySQL converted to DOUBLE in OBIEE 10 gR 3?

  Hi all
  
  I have a problem in OBIEE 10g to I use the MySQL database as datasource direct to the server of the OBI and I have a column in a MySQL table which was designed as the DECIMAL data type (18.0).
  This column is used to measure a length, and values are included in seconds (without decimals), in the form as:
  "1200"
  in the MySQL database.
  
  After the import of the MySQL table associated with the repository of the OBI, the OBIEE converts the DECIMAL data type column to the DOUBLE PRECISION data type automatically.
  
  My goal is to reach the values in this form, certainly in the sense of the term (not at the time!):
  hh mm ss
  
  In order to accomplish, I tried to change the format of column with the ROUND function:
  ROUND (db.table.column / * 3600 * 2)
  
  The problem is that it doesn't work well if values can be divided with no rest for example
  original value: 7200
  new value (ROUND): 2
  
  In the case of my example:
  original value: 1200
  new value (ROUND): 0
  It's false, because 1200 seconds are not equal to 0 hours, I want to see two hours of _0.33333_ OR I much prefer more _0 hour 20 m_
  
  Anyone have any ideas?
  I tried to make a view of database and importing that type of CHAR data in the database, but is not the solution too, because if I filter BI app or try to make a SUM the BI would drop errors...
  
  Kind regards

• How to detect the data type is?

  Hello!

  I built a function of VI. But I want to make it safe - function could detect what type of data is connected to the inputs and only allow certain types of data cabling. How can I do this?

  Thank you

  You could look in polymorphic VI.  They will allow you to connect different types of data.  However, it is not really an option to "do not allow" it.

  If someone creates their own s VI in LabVIEW, then they should pay attention to details like the stress points.  Other than provide good documentation describing the function, inputs and outputs of a Subvi, it's not really necessary for the creator of the Subvi to prevent another programmer to use this Subvi wrongly.

• How to display the data type long using the select statement

  Hai All
  
  I have to select the text of a view. But the text is declared as long and I need to see full view
  
  When I use this
  
  Select the text in all_views where view_name = "DAILY_ATTEND_VIEW";
  
  I have got only half of a select statement
  
  Concerning
  
  Srikkanth.M

  Hello

  SQL> SET LONG 100000
  SQL> select text from user_views
    2   where view_name='MVIEW';
  
  TEXT
  ------------------------------------------
  select e.empno,e.deptno,d.dname
  from emp@sdblink e,dept@sdblink d
  where e.deptno=d.deptno
  

  But it is limited to sql alone. If you use the double click TOAD on the text column in the grid will show you the entire SQL views.
  Unfortunately, there is limitation to consider,
  The largest value that you return from the function would be 32 k (RETURN VARCHAR2), both.
