  • How to update one column from another table

    Hello

    We have some sellers who are defined as employees but without employee_id for some reason any.  So I would like to update the correct number of a view of HR records.  Here is what I tried:

    update of po.po_vendors x

    Define employee_id = (select apps.per_people_v7 person_id y)

    where y.first_name |' '|| y.last_name = x.vendor_name)

    Error received: a row subquery returns more than one line.

    If I use this instruction to check, I'm correct employee_id or person_id home:

    Select apps.per_people_v7 person_id y, po.po_vendors x

    where y.first_name |' '|| y.last_name = x.vendor_name

    When I checked/compared with some old posts here, I could not just see where I did mistake.  Please notify.

    Thank you

    Ning

    Because for the same vendor id, you have a (employee id) id of the person twice in the target table. As Boneist said "fix data, difficulty of the request, fix the requirement...". »

    How many sellers are there in your target table?

  • How can I use ColdFusion to change the structure of database?

    I have a project that requires me to import hundreds of PostgreSQL dBase tables.  Importing is quite simple.  However, I need to rename all the columns to meet my organization s naming conventions.  This forces me to precede a name data type the column name.

    For example... I have three columns NAME, LOCATION, and BRIAN.  These columns are of type varchar, number and date.  These columns must be changed so that new names of columns are vchar_name, num_location and date_edop respectively.

    Since there are thousands of columns, perform this task manually is not plausible.  I think I can use CF to perform the task for me, but I don't know how to do.

    Has anyone done a similar task and would be willing to share some code example?

    Thank you
    Lee

    IF you know how to make these translations with SQL, then you know how to do with ColdFusion.

    If you know only hot to preform these trnalations with a Databasse management tool, you must first learn the SQL used by the tool really to do these translations.

    You can pass ALL SQL instructions through a block of that includes your database management system, and the account used to connect to ColdFusion is allowed to use.

    P. S. it's this last point is important BECAUSE the States of web security well the normal DSN connected to ColdFusion must never have unnecessary permissions, such as create, modify, or remove tables.  So you can very well, (I hope so at least) need to create a special DSN with the necessary permissions for this task.  And, of course, don't let this DSN not be used for other taskes where permissions are not necessary.

  • How can I make sure that changes in a primary key (in the parent table) would also appear directly in the FOREIGN KEY in the child table?

    Forgive my question. I am very new to Oracle.

    How can I make sure that changes in the key primary supplier_id (concerning the supplier table) would also appear directly in the FOREIGN KEY (supplier_id) in the products table?

    Is that not all the primary key and FOREIGN KEY on?

    My paintings:

    I created 2 tables and connect to apply in the data base referential integrity, as I learned.

    CREATE TABLE - parent provider

    (the numeric (10) of supplier_id not null,)

    supplier_name varchar2 (50) not null,

    Contact_Name varchar2 (50).

    CONSTRAINT supplier_pk PRIMARY KEY (supplier_id)

    );

    CREATE TABLE - child products

    (the numeric (10) of product_id not null,)

    supplier_id numeric (10) not null,

    CONSTRAINT fk_supplier

    FOREIGN KEY (supplier_id)

    REFERENCES beg (supplier_id)

    );

    I inserted the following text:

    INSERT INTO provider

    (supplier_id, supplier_name, contact_name)

    VALUES

    (5000, 'Apple', 'first name');

    I expect that the supplier_id (5000) to the provider of the table also appears in the products table under key supplier_id having the same value which is 5000. But this does not happen.

    How to get there?

    Thanks in advance!

    Hello

    What is a foreign key in Oracle?

    A foreign key is a way to ensure referential integrity in your Oracle database. A foreign key means that the values of a table must appear also in another table.

    Ok!??

    What is now the right way to implement referential integrity in your Oracle database that the values of a table must also be included in another table?

    A foreign key referential integrity indeed enfore in ensuring that the value in the child table must have a corresponding parent key (otherwise you will encounter an error, as evidenced by "SomeoneElse"). However, it will never automatically insert a row in the other table.

    If you are looking for a solution that automatically inserts a record in the other table, maybe you should go for triggers:

  • When I update to Firefox, it changes all my fonts. How can I stop if so?

    I have windows 7. I'm stuck on 21.0 Firefox. Each update since then has changed my fonts to the point that I can't get back them. Even when I go and re - change fonts for what they should be, it is not correct. I need to restore my system to 21.0 to recover the correct fonts. I have several programs that I need the fonts to use them properly.

    I had the same problem. Thanks for the info above on how to solve this problem. To summarize how to fix:

    • Open a new window in FireFox.
    • Put this in the address bar: subject: config
    • You will see a list of parameters.
    • Search for: layout.css.devPixelsPerPx
    • Just right click and edit, and then enter a value like 1.0
    • Open a new window of FF and surf any web page.
    • If the width looks ok, you are finished with layout.css.devPixelsPerPx.
    • If the width is not ok, change layout.css.devPixelsPerPx to a slightly different number. On my system, I used 1.03.
    • After that, you can change your font size settings.
    • To do this, tap the tools, Options menu, content.

    The cause of the problem is newer versions of FF had the new thing called layout.css.devPixelsPerPx and its value has not been correctly initialized. The problem occurs to anyone who will update to the new version. It is a bug and should be fixed in the software.

    Nihar

    Hi, Nihar,

    You almost had it! You just need to correlate the subquery for the main UPDATE statement, like this:

    UPDATE     user_table     u     -- USER is a built-in function; it's not a good table name
    SET     password = ( SELECT  encrypt
                   FROM    reset     -- RESET isn't a very good table name, either
                   WHERE   serial     = MOD ( LENGTH (u.username)
                                             , 10
                                   )

  • How to change tables of waveforms?

    Hi, I hope you can help with this.

    I read 6 channels of analog data to a USB - 6008 1000 samples/second, 1000 sample blocks in a loop. The data come from DAQMX as an array of 6 waveforms.

    I want to (y) scale all data such as 0, 1, 2 channels are divided by 3 (because electronics has an op-amp of gain of 3 x on channels) and channels 3, 4, 5 are divided by 15 (because electronics has a 3 x the gain and there is a resistance of 5 ohms and I'm trying to measure the current).

    You might think it's ridiculously easy... but:
    (1) to "scale and offset" labview vi only works on waveforms (no tables of waveforms)
    (2) insert a node of matlab or matscript me does not work only the tables on waveforms,
    (3) with the help of a simple 'divide' VI, it is impossible to define the denominator as just one number... "3" !

    any ideas? as usual, it is the kind of problem, people have to face all the time

    Hi Dave,.

    That's how I'd do it - use the table of values of divisor.

    Hope this helps - example in lv 8.6.

  • How to update text or change the text in the TLF?

    Hello

    I can't update the text in a TLF. This should be pretty basic, but forget something.

    It's the pseudocode:

    pg_xml = new XML(str);
    textFlow = TextConverter.importToFlow(pg_xml, TextConverter.TEXT_LAYOUT_FORMAT);
    var tlf_sp = new Sprite();
    textFlow.flowComposer.addController(new ContainerController(tlf_sp, width, height));
    tlf_sp.x = posx;
    tlf_sp.y = posy;
    textFlow.flowComposer.updateAllControllers();
    addChild(tlf_sp);
    

    Elsewhere, the text should be updated:

    pg_xml = new XML(str);
    textFlow = TextConverter.importToFlow(pg_xml, TextConverter.TEXT_LAYOUT_FORMAT);
    //TODO: figure out how to update text! updateAllControllers doesn't work.
    //textFlow.flowComposer.compose(); //-- Didn't work.
    //textFlow.flowComposer.updateAllContainers(); //-- Though this couldn't be used, I was just trying out, but didn't work either.
    textFlow.flowComposer.updateAllControllers();

    I just need to update the content of a TLF, rather than recreating a new textflow. Any help will be much appreciated.

    If you are importing, the import process always produces a new TextFlow. You cannot import into an existing TextFlow.

  • Download massive updated the planned orders in table msc_supplies

    Hi all

    I need your suggestion below requirement:

    For item RM, we planned order suggested that the CPHA; before releasing it, we want to change Date of implementation and the amount of order, then output the last modified scheduled released automatically to create the PR in purchases & Payables.

    In order to change the planned orders of RM, we export order planned the Workbench of the CPSA in the worksheet and then change dates, quantity, etc. in the worksheet. We want this change data to insert in the table msc_supplies automatically with manually intervene them and followed by releasing these planned automatically orders to create a PR

    We want to know how to achieve this requirement. We want to know the available custom hook and script to insert record in to msc_supplies.

    Have a great day.

    Thank you

    Sanngo

    Hello

    We expect steps below:

    (1) export the planned RM command suggested by the CPSA to the spreadsheet or report.

    (2) prepare the csv file with mandorty field as shown below in the table, i.e. date, quantity, etc. and format the data according to the custom intermediate table created.

    (3) custom concurrent requests created, which is used to locate the data file and upload the data to a custom intermediate table.

    (4) of the intermediate table that we are download the same data in the database MSC_SUPPLIES table (make a validation here check) in the same program. After that a manually scheduled commands added to the table of MSC_Supplies and can be found in the CPSA workbench.

    (4) in the same concurrent application of custom, call "automatic rejection" to release these records of the base table of msc_supplies, where release_flag a value of 1.

    We want to know the required fields need to be updated in the staging table custom and the base table:

    ORGANIZATION_CODE

    ORGANIZATION_ID

    ITEM_SEGMENTS

    INVENTORY_ITEM_ID

    ORDER_TYPE_TEXT

    ORDER_TYPE (5)

    New quantity

    FIRM_QUANTITY

    Argument Plan_ID

    Transaction_id
