  • Update a table with one column of another

    Oracle 11g
    Hello

    i'im trying to update the two columns of table SUPPORT (SUPPORT_X, SUPPORT_Y) with two columns of table POST_HTA_BT (POSTHTABT_GPS_X, POSTHTABT_GPS_Y)

    Understand that the two tables have the colum below:

    SUPPORT (SUPPORT_ID, SUPPORT_PLAQUE, POSTHTABT_ID, SUPPORT_X, SUPPORT_Y,...)

    POST_HTA_BT (POSTHTABT_ID, POSTHTABT_GPS_X, POSTHTABT_GPS_Y,...)

    The SUPPORT_PLAQUE has type varachar. Except the keys, the other columns are varchar type in both tables.

    The point here is to update the support_x, support_y with posthtabt_gps_x and posthtabt_gps_y.But before the update we have Sheik if the fifth number of the support plate is a number of characters from "0" to "9"and the rest of the caracter of the support_plaque is '00000'

    Please note that the support_plaque is stored in the table with the form: "0025800000!"

  • Update of table with invalid identifiers

    Hello!

    I use a third-party plug-in and that comparisons of chemical structures. I want to update a table with the values of the other when the plugin matches two rows. However, I'm a problem invalid identifier.

    Two tables:
    PLATES: a VARCHAR2 columns of PLATE_SMILES, IN_DB
    INVEST: a VARCHAR2 columns of SMILES

    The operator is a binary: jc_compare (PLATE_SMILES, SMILES) = 1 (or 0 if they do not match)

    I want my query to say: "If comparison SMILES, PLATE_SMILES = 1, define IN_DB = 1 for row" - effectively asking if PLATE_SMILES exists in the table INVEST.

    I tried a number of "renditions", all identifiers not valid donations. Here is an example:

    Update (select plate. PLATE_SMILES, plate. IN_DB, invest. SMILES
    plate PLATES
    INVEST invest
    WHERE jc_compare (PLATE_SMILES, SMILES) = 1)
    set plate. IN_DB = 1;


    ORA-00904: "FLAT". "" IN_DB ": invalid identifier


    I hope that this should be an easy fix, and any help is greatly appreciated!

    Yes, a SQLite database will persist between battery pulls.  The database is registered either to internal MEM or removable media (not the device memory), depending on which is available on your device.

    In general, its not considered a best practice to remove your table as soon as it is empty and re - create it again when you want to add data.  This adds extra overhead fresh for the final, delete and insert first for a given table.  Instead, define and finalize your drawing before you create your table.  Once created, review the static schema.

    That being said, for development purposes, it may be easier to provide an easy way to drop your tables while you develop your schema.

    See you soon,.

  • Export an ADF table with default column order

    Hello

    Jdev 11.1.1.5.0

    We have ADF Table with column drag and drop option. Also we have implemented ADF Table with excelHTMl type of export.

    Everything works as expected. Only problem is if we try to exchange a few columns by drag-and - drop option and then export the table, we receive the order of the columns with brewing. But our demand is, the user must obtain the export with the initial order table by default.

    It would be great, if you can suggest an idea to export the ADF table with default column order.

    Thanks in advance,

    MSR.

    I realized the required functionality. We can restore the default order of the columns to aid

       Function richeTableau = this.getFetchResultsTable ();
       Iterator rItr = rTable.getChildren () .iterator ();
       {while (rItr.hasNext ())}
           ((RichColumn) rItr.next ()).setDisplayIndex(-1);
       }

    Then we can call the real export help feature

       FacesContext context = FacesContext.getCurrentInstance ();

  • Best way to update a table with separate values

    Hi, I would really appreciate some advise:

    I need to regularly perform a task where I update 1 table with all the new data that has been entered in another table. I cannot perform a complete insert because this will create data duplicated each time it works, so the only way I can think of is the use of cursors in the script below:


    CREATE OR REPLACE PROCEDURE update_new_mem IS
    tmpVar NUMBER;

    CURSOR c_mem IS
    SELECT nom_membre, member_id
    OF gym.members;
    CREC c_mem % ROWTYPE;


    BEGIN
    OPEN c_mem.
    LOOP
    SEEK c_mem INTO crec;
    EXIT WHEN c_mem % NOTFOUND;
    BEGIN
    UPDATE gym.lifts
    Name = crec.member_name
    WHERE member_id = crec.member_id;
    EXCEPTION
    WHEN NO_DATA_FOUND THEN NULL;
    END;
    IF SQL % NOTFOUND THEN
    BEGIN
    INSERT INTO gym.lifts
    (name, member_id)
    VALUES (crec.member_name, crec.member_id);
    END;
    END IF;
    END LOOP;
    CLOSE C_mem;

    END update_new_mem;



    This method works, but y at - it a (faster) easier way to update another table with new data only?

    Thank you very much

    Almost anything would be better than this treatment of slow-by-slow loop.

    You don't need a procedure, you should just use MERGE for this. See the examples in the section of the MERGER of the doc of the SQL language
    http://docs.Oracle.com/CD/B28359_01/server.111/b28286/statements_9016.htm

    MERGE INTO bonuses D
       USING (SELECT employee_id, salary, department_id FROM employees
       WHERE department_id = 80) S
       ON (D.employee_id = S.employee_id)
       WHEN MATCHED THEN UPDATE SET D.bonus = D.bonus + S.salary*.01
         DELETE WHERE (S.salary > 8000)
       WHEN NOT MATCHED THEN INSERT (D.employee_id, D.bonus)
         VALUES (S.employee_id, S.salary*.01)

  • 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.

  • Unique table with several columns or several tables split?

    Hello

    user13024762 wrote:
    I have a table EMP that has column EMP_ID, EMP_NAME MGR_ID, MGR_NAME, SALARY, EXP_IN_MNTHS, EXP_IN_YRS... etc with multiple columns

    I have the following tables
    EMP-> EMP_ID, EMP_NAME

    Each row in the table emp thie represents a separate employee. I guess other columns in the emp table might be birth_date, social_security_number and status (by example, 'Active', 'Leave', 'complete'). Here's what an employee has (at least) one of. If there is a one-to-many relationship between an employee and an attribute, then you probably want another table for this attribute.

    BISHOP-> EMP_ID, MGR_ID, MGR_NAME

    There is a one-to-many relationship between employees and managers? In other words, an employee may have 2 or more managers? If Yes, then you need another table.
    If there is only a one-to-one relationship between employees and managers (in other words, if an employee is never more than 1 Manager) so why don't you just have a mgr_id column in the emp table?
    Managers are also used for? (This is often the case, as in scott.emp and hr.employees.) If so, do not store their names in the EME and tables of mgr. Store name (and date of birth and other information) in the table emp only and, if you need a table of Bishop, just the emp_id and mgr_id column.

    SAL-> EMP_ID, SALARY

    There is a one-to-many relationship between the employees and wages? In other words, an employee may have 2 or more treatments? If so, how will you use the values? Is a special treatments in some way, as it will be used more often than others? (In other words, you may have a current and past wages salary, but the last wages are rarely used.)
    If you never have more than 1 salary for a given employee, why not just have a sal column in the emp table?

    EXP-> EMP_ID, EXP_IN_MNTHS, EXP_IN_YRS

    There is a one-to-many relationship between the employees and what whether you store in this table?

    etc. with more tables

    What is the best based on

    (1) performance and data recovery
    (2) ease of use
    (3) maintainability

    A one-to-many relationship requires an additional table. If an employee can have up to 3 managers, don't have mgr1, mgr2 and mgr3 columns in the emp table. Use a separate table, with up to 3 lines for the same employee, instead.
    For 1-1 relationships, it is usually best to not have separate tables.

  • Table with 300 columns

    While talking with a friend, he told me that sometimes he uses tables with 300 columns that will be available only once for the extraction of information. For me, it's a little strange because 300 columns looks like a large number of columns for me...

    Have tables with columns as is common practice in the data warehouse? If Yes, can you explain to me on what situations, this can happen and how often?

    Concerning

    We have tables with columns of cca 150.

    You should know that we don't talk to relational systems which are standardized. Its common practice when building data warehouse. Number of columns in the tables will depend on the complexity and the size of your warehouse and the number, size and complexity of your source systems.

    Point is that even now, when the data warehouse is "done", we still add/remove columns changes to warehouse such as changing the source systems.

    I can reproduce the effect in 11.2.0.1 - but not in 12.1.0.1.

    drop table tbl_1;

    create table tbl_1

    as

    Select rownum id

    , lpad ('* ', 50,' *') padding

    of the double

    connect by level<=>

    ALTER TABLE tbl_1 ADD (NUMBER col_4 by DEFAULT 100);

    --> slow in 11.2.0.1; fast 12.1.0.1

    ALTER TABLE tbl_1 ADD (DEFAULT col_4 NUMBER 100 NOT NULL);

    --> Quick 11.2.0.1 and 12.1.0.1

    A SQL trace for two operations (11g) shows that the altar slow (without the constraint explicit non-null) made explicit (and tedious) update of any row in the table:

    Update 'TBL_1"set"COL_4"= 100

    call the query of disc elapsed to cpu count current lines

    ------- ------  -------- ---------- ---------- ---------- ----------  ----------

    Parse        1      0.00       0.02          0          1          0           0

    Run 1 11,63 33.56 8336 1016125 2053531 1000000

    Fetch        0      0.00       0.00          0          0          0           0

    ------- ------  -------- ---------- ---------- ---------- ----------  ----------

    Total 2 11,63 33,58 8336 1016126 2053531 1000000

    The other trace file does not contain the explicit Update. I guess in the optimized case that oracle stores somewhere that col_4 has the value 100 and updates only the line of the block after completing DML operations. But that's just a guess.

  • How to update the table with the number management

    Hello

    I need as there is a loc_tab of the created table as below,

    CREATE TABLE loc_tab
    (
    Country_ID NUMBER,
    country_code VARCHAR2 (3),
    country_name VARCHAR2 (50).
    State_ID NUMBER,
    state_code VARCHAR2 (3),
    state_name VARCHAR2 (50).
    city_id NUMBER,
    city_code VARCHAR2 (3),
    city_name VARCHAR2 (50)
    );

    I inserted records like below,
    COUNTRY_ID     COUNTRY_CODE     COUNTRY_NAME     STATE_ID     STATE_CODE     STATE_NAME     CITY_ID     CITY_CODE     CITY_NAME
    
              IND          INDIA                    TN          TAMIL NADU          CHN          CHENNAI
              IND          INDIA                    TN          TAMIL NADU          TRI          TRICHY
              IND          INDIA                    TN          TAMIL NADU          CMT          COIMBATORE
              IND          INDIA                    TN          TAMIL NADU          MDU          MADURAI
              IND          INDIA                    AP          ANDHRA PRADESH          HYD          HYDERABAD
              IND          INDIA                    AP          ANDHRA PRADESH          SEC          SECUNDRABAD
              AUS          AUSTRALIA               QLD          QUEENSLAND          BRI          BRISBANE
              AUS          AUSTRALIA               TAS          TASMANIA          HB          HOBART
              AUS          AUSTRALIA               TAS          TASMANIA          CCE          CITY OF CLEARANCE
              AUS          AUSTRALIA               TAS          TASMANIA          BUR          BURNIE
    Now, I wanted to update the table such that all ID columns are updated with running number.

    Each ID columns should get incremented so that, for Country_ID column corresponding to "India" If country_id is 1, that there must be one for all the lines with the name as "India". Likewise for "Australia".

    In the case of State, she also has the same logic with numbers repeated until the very name of the State comes.

    For the city, it of course will hold separate ID only because the name of the city will not get duplicated.

    This update must be done in the normal way using simple SQL such as no PLSQL don't like looping, etc... is involved.

    Here are the contents of the table, and that's how the table should be updated,
    COUNTRY_ID     COUNTRY_CODE     COUNTRY_NAME     STATE_ID     STATE_CODE     STATE_NAME     CITY_ID     CITY_CODE     CITY_NAME
                                            
    1          IND          INDIA          1          TN          TAMIL NADU     1     CHN          CHENNAI
    1          IND          INDIA          1          TN          TAMIL NADU     2     TRI          TRICHY
    1          IND          INDIA          1          TN          TAMIL NADU     3     CMT          COIMBATORE
    1          IND          INDIA          1          TN          TAMIL NADU     4     MDU          MADURAI
    1          IND          INDIA          2          AP          ANDHRA PRADESH     1     HYD          HYDERABAD
    1          IND          INDIA          2          AP          ANDHRA PRADESH     2     SEC          SECUNDRABAD
    2          AUS          AUSTRALIA     1          QLD          QUEENSLAND     1     BRI          BRISBANE
    2          AUS          AUSTRALIA     2          TAS          TASMANIA     1     HB          HOBART
    2          AUS          AUSTRALIA     2          TAS          TASMANIA     2     CCE          CITY OF CLEARANCE
    2          AUS          AUSTRALIA     2          TAS          TASMANIA     3     BUR          BURNIE
