Number nav to display records

Hello;
I've created a navigation numbered to make cycling in the DB records. When I created it, it was based on catagoryID. There are a number of categories, and this would put a navigation in the records like this:
1. 2. 3. more > the Previuos Word would appear if you are entered in the records. The net asset value will also automatically if records grew, (more added)

Now, I change things on this 'soft' I don't use categories, but simply want to scroll the setting records 10 records on the page at a time, and only using the DB ID records to scroll. I changed the code and it's the slightest mistake on me now. Here is the code I use:

< cfset CurrentPage = GetFileFromPath (GetTemplatePath ()) >
< cfparam name = default "PageNum_GetRecord" = "1" >
"< cfquery NAME ="tracking"datasource =" "#sitedatasource #" username = "#siteUserID #" password = "#sitePassword #" >
SELECT ID, REMOTE_ADDR, HTTP_USER_AGENT, TRACK_DATE
FOLLOW-UP
WHERE ID = #ID #.
ORDER BY ID
< / cfquery >

< cfparam name = "StartRowOptional" default = "1" >
< cfparam name = default "LignesMax" = "10" >
< cfset numRows = tracking.recordCount >
< cfif StartRowOptional gt numRows > < cfset StartRowOptional = Max(startRow-maxRows,10) > < / cfif >
< cfset EndRowOptional = Min ((StartRowOptional + method - 10), Evaluate numRows) >

< body >
< cfoutput query = "tracking" STARTROWOPTIONAL = "" #StartRow # "LignesMax =" #maxRows #">"
#all my output is here.
< / cfoutput >
< cfmodule
"' model = '... / CFdocs/pageNav.cfm.
totalItems = "" #numRows # ""
numPerPage = "" #maxRows # ""
StartRowOptional = "" #startRow # ""
URL = "#CGI. SCRIPT_NAME #? ID = #ID # & StartRowOptional = #startRow #">"

My error is:

ID of the variable is undefined.


The error occurred in C:\websites\108392zj7\admin\tracking.cfm: line 7

5: < cfset CurrentPage = GetFileFromPath (GetTemplatePath ()) >
6: < cfparam name = "PageNum_GetRecord" default = "1" >
"7: < cfquery NAME ="tracking"datasource =" "#sitedatasource #" username = "#siteUserID #" password = "#sitePassword #" >
8: SELECT ID, REMOTE_ADDR, HTTP_USER_AGENT, TRACK_DATE
9: FOLLOW-UP


Can someone help me understand what it is that I'm missing and why my ID is not présicer?

Thank you

Hi Phoenix,

I have 1 question.

In your query

SELECT ID, REMOTE_ADDR, HTTP_USER_AGENT, TRACK_DATE
FOLLOW-UP
WHERE ID = #ID #.

The #ID # whence?

You also say that 'it's the ID in the DB that is assigned for each record

What is actually the #ID #?

Everything is within a ... ?

In this case, he explains why you get an error 'Variable ID is undefined' because in your code, nothing raises the #ID #.

It is also a good practice to specify the scope of your variables for example, variables.ID, form.ID, url.ID, etc.

I tried a similar example with Next, Previous links and it works fine.

Here is the code below.

I hope this helps.

Kind regards
Yogesh

  • BI Publisher - how to display the number of lines displayed at the bottom of the table on each page

    Hello

    We are the conversion reports Actuate BEEP and not able to understand how to view "Accum.Total = < n >" at the bottom of each page. In the attached report to operate it, "Accum.Total = < n >" must be displayed at the bottom of each page where < n > is the number of lines displayed on the current page and previous page.

    For example, if there are 10 rows in the result set, if the 1st page displays 4 rows, 2nd page displays 3 rows and 3rd page is 3 lines and then Accum.Total = 4 on page 1, Accum.Total = 7 on page 2 and Accum.Total = 10 on page 3.

    Note that we use the property table "allow the lines to break Pages = False" as we do not want a specific line can be split across pages.

    I enclose a sample of report actuate, rtf, BEEP and XML report for testing file.

    Approach used so far-

    1 > I tried to put the counter in the footer, but it seems that only the fields that come directly from the IC can be used on the header/footer. No matter what form text field or variables defined in the report.

    2 > I used approach given in the link below. Using this approach, I am able to view a coded value hard at the bottom of every page (just below the table) but his does not work for the variable (in my case the counter c1).

    https://blogs.oracle.com/xmlpublisher/entry/continued

    3 > on Google, I found a few articles on the page break conditionally as display only certain numbers on a page or the page by section break but in our case, its dynamics and its number of lines to display on a page is driven by data, so I could not think of a certain condition to use in "Condition." ": If" for use as a page break.

    As you said already FETCH retrieves the next line, if any. A query is a request is a request. It returns a result set. A query that uses aggregates returns a result set. A query that does not aggregate returns a result set.

    Your simple COUNT (*) SELECT query returns a result set that consists of a LINE and a line a ONE COLUMN of type NUMBER. Although there is only one column in the result set, what is returned is a RECORD or a LINE. That's why you have to report your data cursor return type a document using the % ROWTYPE or % TYPE attributes or a record structure.

  • How to set the number of lines displayed in a classic report when running?

    Hello

    Our client has several hardware configuration standard customer and want to allow end-users to choose their 'view profile' at the time of the connection. This "display profile" would contain some predefined values for these configurations material and supposed to give various parameters that must set the number of lines displayed in a classic regional report.

    I tried to provide parameters on the report of the region, but he has refused to accept anything other than numeric values. Is it possible to do?

    Best regards, Tamas

    The link is about the closest correlate in the documentation to the description of the attribute Number of Rows (point) .

    Looks like you tried to write - in vain - a name string or change of item in the attribute Number of Rows . The attribute Number of Rows (point) is the one that can actually do. For a list of items in the application, click the icon of the flashlight next to her.

  • Sum on multi block record for only displayed records

    Dear all,

    I've been invited below question on interview session and I really do not come upwards with a logic to accomplish.

    In a multi record block, not the displayed items property has the value 10. In this block, an element is placed named current_rate (Number data type).

    While the form is running, it will display 10 records, and I need to display the sum of the current_rate for these 10 records. When I scroll to display multiple records, this amount must also be changed based on the record number of display. Is it possible to make forms to operate this way?

    Please advice.

    Thank you and best regards,

    The roots.

    Another way - create element (e.g. "sum") in a block of control (for example, "cb") and write this:

    -Prior REQUEST for the block of data (for example "E1")

    : cb.sum: = 0;

    -After REQUEST for the block of data (for example "E1")

    : cb.sum: =: cb.sum +: emp1.salary;

    Query the property size array in a data block (specifies the maximum number of records Form Builder to retrieve from the database at the same time)

    must be 0 (default = the number of records can display the block, as indicated by the property of block number of records displayed).

    1. when I create text boxes, the label is displayed to the left of the text box. How can I display label above the text box
    CGH

    Label
    TextBox

    Instead of

    Text box label

    2. when I ask report showing my data, that it shows that 15 records per page, for the next set of records, I need to click on the following icon at the bottom of the table to go to the next page.
    How can I view all on the same page?

    Thanks for help

    1. simply check this using the Horizontal / Vertical alignment of attribute in the section of the label of the element of the Page definition.

    2. in the report of the attributes, the value of the plan of paging None; and the number of rows and number of maximum lines to more than the number of rows that will be returned by the report query.

    (You should only ignore this last you really know that the number of lines make this a reasonable option.) Nobody is going to want to scroll through thousands of lines or wait 5 minutes for total information overload. You wouldn't be popular with your admins/ISP network due to the excessive bandwidth consumed either.)

  • Reduce the number of cells displayed by indicator table

    When I'm hacking through a few screws I inherited, I often create a table indicator to track data.  I have an oversized indicator, i.e. perhaps seven cells for what turns out to be a five-element array.

    I can easily increase the number of cells is displayed but seem not to be able to reduce their.

    Y at - it a trick I'm missing?

    When you first place a 1 d table control or an indicator, LabVIEW is unclear if you can stretch it horizontally or vertically.

    The RESIZE tool, that you get so something on the lower right.

    Once you have decided that you want to extend vertically, if you want to resize once again, the point of RESIZING is at the bottom of the Center.

    If you have it stretched horizontally and want to resize again, the point of RESIZING is the center of the right side.

    Is - this good user interface?   No, if you ask me.  But nobody asked me.  It's the way it is, however.

    Hello

    I hope that you can adapt the solution in #5 response above to your table.

    Here is another common way to do this sort of thing, by using a NOT EXISTS subquery:

    SELECT *.

    Contract_coverages m - m is hand query

    WHERE DOES NOT EXIST)

    SELECT 0

    S contract_coverages - s is subquery

    WHERE s.contract_id = m.contract_id

    AND s.coverage_id = 4444

    )

    ORDER BY contract_id, coverage_id

    ;

    EXISTS subqueries are almost always correlated with their Super request.  Why?  Discuss.

  • Number of instances + display

    Hi, I'm currently having a problem with getting the instance Manager to count and display the current number of subforms.

    I have a TextField called TextField117 in a subform called Row24, which is in a subform called Set2.

    I also have a button called 1 button that creates a new instance of Set2 each time on it.
    What I'm trying to make, is that TextField117 gets automatically filled with the # whenever the button is clicked, so in the first set2(the original), it will show 1.

    Then when the button is clicked, it will create an another set2 which has its own textfield117 and I want that textfield117 to display 2. (a meter). and so on... 3, 4... 5 6...


    If there is someone who could help, I'd appreciate it. Thank you!

    Hello

    If you set TextField117 to calculate - read-only and put the code in the calculate event you can have the field contains the value you want

    in the calculate event, you can write the reference_syntax necessary to access the parent set2 and retrieve the index with the following:

    this.rawValue = (this.parent.parent.index + 1) m:System.NET.SocketAddress.ToString ();

    Depends on how many parents must Access set2, must be paid according to the hierarchy...
