• change the data type of the columns

  Oracle 10g version.
  I have a table with 150 columns.

  Do we have a query for this task?
  
  Thank you.

  Not knowing yet what you meet John:

  If your table is empty, you can use the datadictionary to generate a statement and run the query to a file that makes the DDL using dynamic SQL or spool and run that...

  Example:

  Tabel is aangemaakt.
  
  MHO%xe> select column_name, data_type from user_tab_columns where table_name = 'BLA';

• script to change the data type of column

  Hi gurus of the oracle.

  I have 190 tables in my database.

  I have the column type CHAR of all these tables data.

  I need to change the data type of CHAR in VARCHAR2 for all these tables...

  There the script to change the data type of all tables at once?

  Please help me in this regard.

  Thanks in advance

  Hello

  There is nothing built-in to Oracle SQL to do.  Maybe your front-end has certain characteristics.

  You can write dynamic SQL statements to do.  In other words, you can write a query that the output is a SQL script like this:

  ALTER TABLE TABLE_A CHANGE (A_TXT1 VARCHAR2 (5))

  A_TXT2 VARCHAR2 (10));

  ALTER TABLE TABLE_B CHANGE (B_TXT1 VARCHAR2 (5));

  with one row for each column of type CHAR.  Notice how the first line of output for each table begins with ALTER TABLE... but the later lines at the same table.  Similarly, the last line of a table (which will be the same as the first row, if the table has only one column of type CHAR) to end with a semicolon, but other lines are not.

  Here's a way to generate and execute such a dynamic script in SQL * more:

  -Disable the features that make the output easy to read, but hinder the execution
  SET FEEDBACK OFF
  SET LINESIZE 500
  SET PAGESIZE 0

  -Create fix_char.sql
  COIL c:\some_pathename\fix_char.sql

  SELECT THE CHECK BOX
  WHEN ROW_NUMBER () OVER (PARTITION BY table_name
  ORDER BY column_name
  )  = 1
  THEN 'ALTER TABLE ' | table-name
  || "CHANGE (").
  ELSE «»
  END
  ||        column_name
  ||        "VARCHAR2 (').
  ||        DATA_LENGTH
  ||        ')'
  ||        CASE
  WHEN ROW_NUMBER () OVER (PARTITION BY table_name
  ORDER BY column_name DESC
  )  = 1
  THEN '); "
  Output END AS
  Of user_tab_columns
  WHERE data_type = "CHAR".
  ORDER BY table_name
  column_name
  ;

  SPOOL OFF

  -Turn on the features that make the output easy to read, but hinder the execution
  SET FEEDBACK ON
  SET LINESIZE 80
  SET PAGESIZE 50

  -Fix_char.sql performance
  @c:\some_pathname\fix_char

  It's good to change all the CHARIOT of VARCHAR2 columns.  The CHAR data type is nothing trouble.

• change the data type of column in a view

  Hi gurus,

  Please suggest.

  
  I have been created as below in the region of production.

  CREATE OR REPLACE TYPE PROD. (OBJECT) ACE FEATURE_CUSTOM_LIST_OBJ
  TERMINAL_FEATURE_ID NUMBER (8).
  DATA_VALUE NUMBER (8)
  );
  /

  
  And the view is created below the base have the PROD. FEATURE_CUSTOM_LIST_OBJ

  CREATE OR REPLACE FORCE VIEW PROD. TERMINAL_FEATURE_TYPE
  (
  TERMINAL_FEATURE_ID,
  DATA_VALUE
  )
  AS
  SELECT
  TERMINAL_FEATURE_ID,
  DATA_VALUE
  TABLE)
  CAST)
  PROD. TERM_RELATED_REF_DATA. GET_TERMINAL_FEATURE_TYPE AS PROD. FEATURE_CUSTOM_LIST_TAB));

  Examples of data must be inserted into the display

  TERMINAL_FEATURE_ID	DATA_VALUE
  12	0
  12	1
  12	3
  11	THERE
  11	N

  If iam thinking is possible that we can change the data type of number of varchar2 data type column in a view?

  Or should I follow create or replace type as whenevr the nonnumeric data tries to bring into view
  sound by giving the number plsql for digital character conversion error since it is a number of data type here.

  I have been created as below in the region of production.

  CREATE OR REPLACE TYPE PROD. (OBJECT) ACE FEATURE_CUSTOM_LIST_OBJ

  OK - but it is a SCALAR - not a collection object

  And the view is created below the base have the PROD. FEATURE_CUSTOM_LIST_OBJ

  CREATE OR REPLACE FORCE VIEW PROD. TERMINAL_FEATURE_TYPE

  No - it isn't. Your type of object is a SCALAR - not a collection. You need create a view on a table or a collection that is treated as a table.

  DDL perspective you posted doesn't even mention your FEATURE_CUSTOM_LIST_OBJ.

  Have you tried using TO_CHAR to format the number as a string?

• 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.

• using case, but by changing the data type of diff

  Hi guys, I am creating a view and selecting in a column that has a value of-1, 0 or 1, it's very good and I was about to use a case statement to convert the - 1 to "n", but obviously I can't do what data types do not match, I can't change the data type of the original column until someone knows how I could achieve This or a similar output, for example, is there a way to add an extra column to the view and just copy the numbers to the horizontal except for when it is - 1, we will copy a "n" throughout. the new column might be char and we could convert the numbers to a char when their through copying. Is it possible to do and if so could someone explain or give me an example of how to do it.
  
  Thank you.

  An alternative to the above:

  case when col1 = -1 then 'N'
       else to_char(col1)
  end

  In the printing preferences, use the closest 'brochure' or 'thick' or other media type cardstock that you will find in the list of available paper types.

  Example:

  Control Panel > display icon > devices and printers > right click on your printer >

  Printing preferences > tab paper / quality > media

• To change the data type of control/led

  Is it possible to change the underlying data type of the indicator or a control?  I a VI that I want to use that accepts any type of data (essentially data varriant) and display it accordingly.  I have different controls selected to display data of different types in the sense of data vs decimal boolean data vs integer, but certain types of data will be of type uint32 vs int16 vs uint64 etc..  Is it possible to programmatically change the data type, so I need to have all the combinations of indicators?

  The short answer is no. The long answer is that LabVIEW has not 'generic' controls that allow you to display any type of data (apart from the variant of course). There are several ways to address this problem, but all require you as the programmer to manage explicitly each type of data you could possibly meet. Here are some possibilities (in no particular order), please let me know if you would like to help a particular implementation of these.

  1. Force incoming data to variant, use the info option to determine the data type of the original data in a case structure (open G can do this VERY easy), have an indicator on the front panel for each type of data you want and hide those unused
  2. Use a sub-group of experts on the front panel and sub - vi call of to view specific types (that lends itself very well to encapsulate your data in a class and you leave OOP allows to expand into different types of data)
  3. Use a tab with the variant (similar to option 1) control put each kind of data in its own tab, enable only the current
  4. Do a Control-X to accept a Variant option 1 under the hood
  5. Just as a string of format and use a string indicator

  That's all I can think of right now, once again, let me know if you need more information/help on the options.

• Change the Data Type to node e/s on PXI-7841R FPGA

  I would like to change the data type for the node FPGA of e/s on my card FPGA 7841R (simulation). So far, I have raw data (I16). I want to test something with the calibrated data (FXP).

  The cRIO, you usually go to the properties of module to change the calibration mode...

  I searched 7841R documentation and could not do any weather information this calibration mode was also available on this map.

  Any tips?

  Vincent

  The new maps in the series R offer node fixed point IO (for example, the SMU-7858R), but as mentioned all the old PXI based cards R-series offer only modes of measurement I16.

  Page 22 manual R series is about how to do this conversion: http://www.ni.com/pdf/manuals/370489g.pdf#page=22

  Specifically, it notes that you can calculate the voltage by (output Code I16) * 10.0V / (32 768).

  Even if this can use FPGA resources, it records the host do the same conversions. RT old target with slow processors doing the conversion of I16 or FXP to SGL on the FPGA has saved a lot of time CPU

• [Solved] When you change the file type for RAR files, it also changes the file type of the ISO XP files

  I tried to change the file type description, as well as in default and the icon for the rar and iso programs file types inmenu\ tools\folder options\file typest\advanced, but to change the settings on a file type automatically changes settings on the other.

  How can I do this via regedit?  What can cause a bug?

  Hello

  1. How are you sure that you change the individual file extension and not the entire folder?
  2. how exactly you try this?

  To change a name of file, all you have to do is right click on the file, and then click Rename, instead of the path you describe in the thread.

• You cannot change the output type and format in the page requests system - PeopleSoft process

  Hi all

  When I navigate to the PeopleSoft process scheduler page and try to run a process I see the output type and format web and txt only. I am unable to change the output type and format. All formats and types of output are marked as active in the system settings page. I'm super user of the system as well. I have as well the role of Admin ProcessScheduler. I would like to know if someone has already faced similar problems.

  Run the following SQL query to your OPRID:

  SELECT A.CLASSID, PSPRCSPRFL A.OVRDOUTDEST, PSOPRDEFN B WHERE B.PRCSPRFLCLS = A.CLASSID AND B.OPRID = '';

  Make sure that OVRDOUTDEST = 1.

  If it's 0 then you have to fix your configuration profile of the process as follows:

  -Main menu > PeopleTools > Security > list permission > CLASSID research (white list) back to top query

  -Go to the process tab

  

  -Click on "process the profile permissions

  

  S ' ensure that 'substitute an output Destination' is checked. Click OK, and then save.

  

  This should solve your problem.
