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_IDDATA_VALUE
120
121
123
11THERE
11N

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.

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

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

  • 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 on large partitioned Table Tablet

    Hello

    I was tasked to change a certain NUMBER of collar to a colonel VARCHAR2

    It is usually an easy task, but I ran into several challenges due to the size of the table, the second major problem is the compression of the table.

    To begin with, the Table and index are 4.4 to and hold around 11 lines billion. That the Table is compressed, not the index.

    The first option was to add a new collar of VCHAR, update from the Col de NUM, file and then drop the colonel NUM


    We ran this test in the Test environment and because discovered Compression Table that you can only mark the column is not used, and it can only be moved permanently from the Table if you unzip the whole Table and run «...» REMOVE the UNUSED COLUMNS'.

    The second way is to create a separate Table copy with the values of the source of neck, then write to null to the source of neck, change data Type when its empty and then update the source again with the copy Table values.

    The second option, that's what I'm testing, but I work with nearly 30 million lines by daily score, inserts take very long to fill.

    How can I make faster inserts between the Source and the copy Table?

    What other channels follow to accomplish the task above?

    Concerning

    Stephan

    Nowhere in your proposed solution was necessary for you to understand why the data source changes, its as simple that to take what is ons the table (all the facts in the original post) and offering the best way on the basis of previous experience or oracle skills acquired over time.

    If you spent so much time and thought to help with a solution that you did on WHY complain, you could have provided some feasible solutions already.

    No thanks to your information irrelevant and unnecessary, I've implemented a solution already.

    1 export the Source Table

    2. create a 'replica Table' using the DDL source using a temporary table name

    3. import all Partitions in the Table new

    4. before the Cut-Over, synchronize the changes from the Source to the replica Table

    5 rename the Source

    5 rename the Table of replica for the Original Source Table name

    6. slide the original Source Table

  • change the data type of a column

    Since the previous post: how to change the data type of column number to varchar2 in oracle10g

    My question is:
    If the table half million records

    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.

  • 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

    We use the Oracle Database 11g Release 11.1.0.7.0 - 64 bit

    1. create the new column at the end of the table.

    Unfortunately, you posted in the wrong forum. This forum sql developer and your question belongs in the database - forum general question that the issue has nothing to do with the sql developer. As the forum title says "SQL Developer (not for general questions of SQL/PLSQL)".

    1. open a new thread in the General database forum.j
    Database General Discussions

    2. change this question to post the link to the new question and ask people to follow.

    3. Mark this question ANSWER so people will follow in the other forum

    If your question is to choose between the first choice that actually works
    >
    1. create the new column at the end of the table.
    2. run an update to populate the new column in the table
    3. remove the old column of table
    4 rename the new column for the original name of the column

    >
    You cannot rename the new column for the original column name (step #3) because this would have two columns with the same name. And you can move the old column of table (step #4) because you can never do step #3.

    What did you think?

    When you post in the other forum, you must provide the data types of the two columns involved: the old and you want to take it.

    If you can do it offline you can use a DEC (create the select table) to create a new table that contains the new column and data and does not include the data or the old column. Who would make the best because it could make the new table NOLOGGING and create the table and data in parallel.
