Dynamic table with random records

What I'm trying to do is to select random records from a table and display them in a dynamic table with columns maximum equal to 3 and the 4th record to be on a new line. Here is what I have at the moment and he strives to select random records, but has no function to define the columns of a table. If there is a easier way feel free to let me know. I tried different ways to do it, but none seem not to work.

< CFQUERY NAME = "getItems" DATASOURCE = "absi" >
SELECT catfit.*, modcats.*, prodmat.*, prod.* FROM catfit, modcats,.
prodmat, prod WHERE prodmat.prodid = catfit.prodid and catfit.catid is modcats.catid
ORDER BY ASC modl < / cfquery >

< cfif getItems.recordCount >
< cfset showNum = 3 >
< cfif showNum gt getItems.recordCount >
< cfset showNum = getItems.recordCount >
< / cfif >
< cfset itemList = "" > "".
< cfloop to = "#getItems.recordCount # '1' = ' index 'i' = >"

< cfset randomItems = ListAppend (randomItems, random) >

To start a new line after 3 disks, do something like this.

You should also know that your approach is very inefficient in what you bring to cold fusion more data that you need. First you select all fields from 3 tables when you don't seem to use all the. Then, you select all the records and you only want to use 3. There are better ways out there, but they are specific db and you didn't say what you use.

  • create a table with 2000 records

    Hello

    can someone guide me to create a table with 2000 records
    the columns and data types are as follows
    number of inventory_item_id
    number of organization_id
    number of process_flag
    transaction_type varchar

    number of min_minmax_quantity

    process_flag is always have a value of 1, set_process_id always has the value 3 and transaction_type should be done with the update and the remaining columns will have different values

  • Dynamic table with drop-down lists

    I have a dynamic array with a header row, row in Section, and footer.

    Section has the cells (columns) next: Cell1 (drop-down with locations), button (to remove the line), CCode (RAL color Code), CName (name of the color).

    I start with 1 row.

    now what I want to do is, when they select in Lignesde for example RAL 1003 (rawValue '1') then in CName must appear the name "yellow signal" (rawValue '1').

    I am using javascript

    My first problem is how do I know what value is chosen, because this does not work:

    If (this.rawValue == 1)

    {

    xfa.host.messageBox ('Today')

    }

    and on the other hand, how to set the CName value

    because it affects only in the first cell CName:

    xfa.form.DataSheet.TechnicalInformation.Markings.THatchPatterns.Section.CName.rawValue

    = '1';

    Please help me, I'm totally lost

    solved the problem, instead on the change event to put the script on the exit event.

    and the trick is the following line:

    xfa.resolveNode ("THatchPatterns.Section [" + this.parent.index + "]"). This.rawValue = CCode.rawValue

    Want to get answers that work?  Then make sure that the CREATE TABLE and INSERT statements you post too much work.  Test (and, if necessary, correct) your statements before committing.  You have a stray "." in the first INSERT statement for received_bills and receikved_bills.status is defined as VARCHAR2 (5), but all values are 6 characters long.

    There are 5 lines in send_bills that are similar to the

    10 OCTOBER 2015 19 A1

    Why do you want that 2 rows like this in the output, not 1 or 3, or 4 or 5?  Is it because there are 2 matching rows in received_bills?  If so, you can do something like this:

    WITH rec AS

    (

    SELECT the reference, payment, code

    , ROW_NUMBER () OVER (PARTITION BY datum, payment, code)

    ORDER BY NULL

    ) AS r_num

    OF received_bills

    Situation WHERE = 'SUCCESS'

    )

    send AS

    (

    SELECT the reference, payment, code

    , ROW_NUMBER () OVER (PARTITION BY datum, payment, code)

    ORDER BY NULL

    ) AS r_num

    OF send_bills

    )

    SELECT send.datum, send.payment, send.code

    REC, send

    WHERE send.datum = rec.datum

    AND send.payment = rec.payment

    AND send.code = rec.code

    AND send.r_num = rec.r_num

    ;

    Note that the main request is very similar to the query you posted, but the last condition has changed.

    If you need to insert these lines in another table, you can use this query in an INSERT statement. There is no need of a loop, or for any PL/SQL.

  • Create a table with blank records

    Hello

    I want to create a form in a table to insert several records! However, I have difficulties to identify ways to display the form as 'not empty' i.e. no table existing records appear on the form. I tried to resolve the query, the form is based on the 'automatic' query returns no records, but this caused the fields "disappear". Can anyone recommend the best way to do it (if possible)

    Kind regards

    Kevin.

    Kevin,

    In this case what you can do, is make the unconditional dynamic action and change your query does not return all records.

    select
        "EXPENSE_ID",
        "DESCRIPTION",
        "SPEND_DATE",
        "SPEND_COST"
      from "#OWNER#"."EXPENSESSPEND"
     where 1=2
    

    See you soon,.

    Hello world


    I created a dynamic table with button to add a line


    Please can someone tell me how to avoid the overlapping of dynamic array objects below when several lines are created?


    what I wish is that the table bumps everything on its way like MSWord packaging option


    Please provide a flash tutorial if you can train a lot of people ask this topic

    Hello

    Use fluid page layout to avoid overlapping of table on other objects. This fluid layout must be set on the container parent (form/subform) of the table. Put also other objects in the same container. It results in dynamic container resizing, whenever the new row is added.

    $arrGroups = explode (",", $strGroups);

    If (in_array ($UserName, $arrUsers)) {}

    Thank you for your time!

    Nowhere on this page I see that you have found the "UserID" variable that is used to query the database of cars everywhere.

    You must get that table "user" when a successful connection occurred.

    Go to your login page and find the code which queries the database (it will look something like the below, your request will be slightly different)

    $LoginRS__query = sprintf ("SELECT username, password loginUsers WHERE username = %s AND password is %s",

    MAKE SURE YOU add to THE QUERY "UserID" (see below.) This is the column of your 'user' table and the foreign key record unique identifier in your table 'cars')

    $LoginRS__query = sprintf ("SELECT UserID, username, password AND password loginUsers WHERE username = %s is %s",

    Then, find the lines of code below:

    $LoginRS = mysql_query ($LoginRS__query, $MyConnection) or die (mysql_error ());

    $loginFoundUser = mysql_num_rows ($LoginRS);

    Include these two lines of code directly after the above code:

    $row = mysql_fetch_assoc ($LoginRS);

    $UserID = $row ['UserID']

    Can find these lines of code:

    If {($loginFoundUser)

    $loginStrGroup = "";

    Declare two session variables and assign them

    $_SESSION ['MM_Username"] = $loginUsername;

    $_SESSION ["MM_UserGroup"] = $loginStrGroup;

    Add this line of code directly after the above code:

    $_SESSION ['username'] = $UserID;

    Now, go to the login page of success (whatever you call that)

    Find the code at the top of the page below:

    If (! isset {})

    session_start();

    }

    Add the line of code below:

    If (! isset {})

    session_start();

    $userID = $_SESSION ['username'];

    }

    Look for the query:

    @mysql_select_db ($database_MyConnection, $MyConnection);

    $query_cars = sprintf ("" SELECT * FROM cars WHERE UserID = %s ", GetSQLValueString ($colname_cars,"int")");

    $query_limit_cars = sprintf ("%s LIMIT %d, %d", $query_cars, $startRow_cars, $maxRows_cars);

    $cars = mysql_query ($query_limit_cars, $MyConnection) or die (mysql_error ());

    $row_cars = mysql_fetch_assoc ($cars);

    and replace with:

    @mysql_select_db ($database_MyConnection, $MyConnection);

    $query_query_cars = "SELECT * FROM cars WHERE userID ="$userID "";

    $query_cars = mysql_query ($query_query_cars, $MyConnection) or die (mysql_error ());

    $row_query_cars = mysql_fetch_assoc ($query_cars);

    $totalRows_query_cars = mysql_num_rows ($query_cars);

    Now, you can pass the details of the car associated with the user ID in the 'user' table and a foreign key in the table "cars."

    You probably want to use a / while loop to get all the information from the database. With a DW repeat region behavior.

    I want just a dynamic SQL code for the insert with FORALL statement would adopt as well as collections.

    Doesn't make much sense.

    Extract you the data from the SQL engine in the table of the record type. If the output data that cursor SQL must be read in the SQL engine and copied into the memory of PL/SQL engine.

    Then, you send that VERY SAME DATA back to the SQL engine to be used by a SQL insert cursor.

    Where is the logic behind the extraction of data from SQL in a PL/SQL table structure and then push this same structure table on the SQL engine database? What is the purpose to send data on a detour of underperforming and non-scalale through the PL/SQL engine?

    You have any justification (technical or functional wise) to back up this absurd approach?

    Why this can be achieved using a single SQL cursor that does both the choice (extraction) and (in bulk) insertion - using the plain old INSERT... SELECT structure?

    And if the insert is variable, then what? Create a dynamic INSERT... SELECT cursor and execute it (using bind values). This simple... Right?

  • DB update multiple records in a table with a form

    I'm developing an online proofing system that displays a number of images and then allow the client to approve each image, but also to comment.

    I currently have a configuration table with the different elements (an image dynamically takes its name, details about the image and the required form fields). See this Image for layout

    I would then apply a repeat region (the number of signs vary) and you want to update all records with feedback from the customer and approval with a single form. How this is done? I downloaded a trial of the Toolbox for developers, but the documentation is horrible. I'd be willing to buy an extension that will allow, as appropriate.

    I found an extension that does this in two minutes:

    Great software, highly recommended. Easy to figure out and got this "problem" solved quickly.

  • I'm trying to generate a table of random numbers 30. After each 5 readings a new vi must open and indicate to the user than 5 readings were made. and continue with the generation of the table again.

    because I don't have a sensor now, I am currently generating a table of random numbers 30. After each 5 readings a warning should be given to the user 5 readngs are completed. This cycle must be repeated. the size of the table is 30.

    Please help me, waiting for response as soon as possible.

    Once I have the transducer, I'll take 30 analog samples and then after each 5 smaples this wraning will be displayed din a new VI

    Use a while loop with a delay time representing your sampling interval.

    Use is equal to the count Terminal to see if 4, then 4th iteration = 5th sample.

    Use a box structure. The real deal will only run on the 4th iteration.

    In the case of true place a Subvi with your message of your choice in the front panel. Go to the properties of the VI window and set ' open the front panel when it is called.

    The condition to closing of attention is not given to your description.

    Consider that rather than usign a Subvi to do this, you can use the "dialog box one/two/three button" or "display message" live in the palette "user interface and dialogue."

    Please try it out and send your own VI. Do not provide us with a working solution.

    Kind regards

  • Best way to generate a record per day from a table with the dates of the FEP/exp

    Hello

    A table equipped with various attributes and a date of eff and exp. for example Attributeto, 05/01/2012, 16/05/2012

    We want to create another table in this table for a record per day. for example 16 documents.

    What is the best way to achieve this in OWB?

    Thank you

    Assuming that you have a calendar table, then you can reach your rate table corresponding to the date table schedule between the table rates start date and end date.

    Something like:

    Select a.rate, rate_table b., calendar_table b.
    where b. between a.start_date and a.end_date

    should translate easily into a join of two tables in OWB?
