Mathematical functions on db TinyInt columns does not work?

I have several columns with integers stored using the SQL TINYINT data type. I am trying to add the columns and pass the average of Coldfusion:

< name cfparam = "avgrating" default = "#rsgetratings.ratingone # + #rsgetratings.ratingtwo # / 2" >

and #avgrating # guard display text without running the mathematical function as such:

2.000000 + 2.500000 / 2

You must put the variables in brackets, so that they are treated

#((rsgetratings.ratingone + rsgetratings.ratingtwo) / 2) #.

  • Satellite A100-499 - function for the WiFi button does not work

    Hello, I have a Toshiba Satellite A100 - 499 PSAA9E.

    I formatted my laptop and installed XP with SP3. I downloaded and installed the drivers (in the right order) for this OS of the toshiba - Europe.com and everything is going well except Fn + F8. It is assumed that this combination has toggle Wifi & Bluetooth. When I switch side 'off' position and I press the keys, appears a message saying that I should switch to position 'on' but when I switch lateral position 'on' and I press Fn + F8 it does nothing.

    If I want to disable the wi - fi I have to do it with other methods: the function key does not work correctly.

  • Date filter column does not work

    Hello

    I use jdeveloper 11.1.2.4.

    I have a table with a side of column and the date filter.

    The date comes from a view object, based on an attribute of type Timestamp.

    The format is: MM/DD/YYYY.

    When I enter a date or choose a date in the date picker and press on enter the table is empty.

    Why the date filter does not work?

    Thank you very much!

    Thus, it is a problem.

    In order to work, you must somehow truncating HH part, the same as if you were doing SQL tronque().

    There are several ways to do it, but, maybe you can change SQL of VO and add a new truncated attribute one?

    And rather original attr, you can filter a new?

  • 2 text flow 2 individual images for column span column does not work

    Can I put in place of master pages so that each page has a 2 col frame and cover so setting column works?

    Thanks for the help.

    Jon

    OK, I think I know what is happening.

    Primary text blocks behave a little differently blocks of ordinary text on the master page. With a regular set of frames related masters, you hold down the SHIFT key when you move the text to enable auto-flux of an image to the image and have automatically added images and pages. Primary text blocks are designed to work with Smart Text Reflow and you simply click the cursor loaded inside of them and STR returns to add pictures and pages. If you hold down the SHIFT key while trying to text in a primary text block which frame is skipped, and new ordinary frames are drawn by using your column guides. You can see that cheek if you look at the cursor loaded – as soon as you press the SHIFT key, it will pass icon text in parentheses (to indicate that the text will be placed into an existing framework) the boom wave within a difficult angle (to indicate the text will be "automatic formatting" in a thread of new frameworks rather than use any existing framework).

    Set up your document originally with two columns, which makes your main text frame a frame of two columns, but this also means that if the main frame is ignored during the auto-flux, you will get two independent columns per page.

    Bottom line here is just a click away within your framework and not hold down the SHIFT key. And turn on Smart Text Reflow to primary in the preferences text blocks if you had it.

  • filter on a column does not work? PHP

    I have a column (payment_type) in the php database that is in a table called host_payments. It has values that can be called 'depot' in the column

    I want to exclude this value

    I made my request

    "SELECT * FROM plus_signup, host_payments WHERE plus_signup.userid = host_payments.payment_userid AND plus_signup.latestPaymentMade = 0 AND plus_signup.payment_option = 1 AND host_payments.payment_type = 'deposit" ";

    It works and appears all the records that have deposit and works very well, but then I add exclusion

    "SELECT * FROM plus_signup, host_payments WHERE plus_signup.userid = host_payments.payment_userid AND plus_signup.latestPaymentMade = 0 AND plus_signup.payment_option = 1 AND host_payments.payment_type! = "deposit" «;"

    Then, I get the error return

    You have an error in your SQL syntax; consult the manual for your version of the MySQL server for the right syntax to use near '! = ' deposit "on line 1

    I tried not to mention the "depot" and changed to file

    then get the following error

    You have an error in your SQL syntax; consult the manual for your version of the MySQL server for the right syntax to use near '! deposit =' at line 1

    can someone give me advice?

    Thank you

    It's pure speculation, but it might be worth trying:

    "SELECT * FROM plus_signup, host_payments WHERE host_payments.payment_type! = 'depot' AND (plus_signup.userid = host_payments.payment_userid AND plus_signup.latestPaymentMade = 0 AND plus_signup.payment_option = 1) ";

    Hi user7417334,

    How did you define this measure? Did you do in the general tab (' logical use existing columns as source ")? If so, try to specify it instead on the Data Type tab.

    (1) uncheck "use logic existing columns...". »
    2) click the Data Type tab
    3) double-click your physical source
    (4) in the new box, make sure "Display unmapped columns" is checked
    5) click on the button next to your new column name
    (6) specify your formula here
    7) click OK until you return to the window of Data Type
    8) click the aggregation
    (9) set the SUM aggregation
    (10) save RPD and recheck your report.

  • How is it possible that Firefox 3.6.28 with intelligent search functions and the latest version does not work?

    I noticed that when I'm on Firefox 3.6.28, try to look for something, not looking but sometimes opens directly the most appropriate result. It's amazing and really fast. Why this feature is not included in the latest version.
    Thank you

    When you type words in the address bar, Firefox will search using any motor is selected in the search bar. You can install a "Browse by name" or a "I m Feeling Lucky" search engine

    If you want the search engines separate in the address bar and the search bar, install the module keyword search.

    The reasoning was that 'Browse by name' and "I m Feeling Lucky" are far from perfect. Rather than risking to send users to sites that are not what they were looking for, it was decided that always show the results of the research was a better option.

  • Adpatch function of e-mail notification does not work

    Hi all

    I'm about to apply a huge patch (12.1.1 patch) which will have at least 12 hours. When I was testing this before that I have answered the question about 'Yes' email notification and added my email address, but for some reason adpatch did not send email when a worker failed.

    How can I study the origin of this problem? Where adpatch reads information from the SMTP server of?

    Any comment is appreciated.

    Thank you

    You must configure the e-mail of the BONE - test telnet SMTP to perform according to them (how to perform a significant Telnet SMTP test to troubleshoot Java Mailer to Send Notifications by e-mail [753845.1 ID]). If you can send an e-mail message from the operating system, you should be able to receive emails from adpatch session.

  • Really simple question, function and scroll stop bar does not work

    I worked on different parts of this VI separately, when I put it together the scroll bar and stop working stopped button.

    In the individual VI, both are in the while loop. In the end, I was a scroll bar and a stop to apply every 5 while loops.

    I tried to take the helm of scrolling in and out of the first loop to attach to the rest, but it still doesn't work.

    I'm sure that there is a simple answer that is really stupid, but I played with him for a while.

    I have attached the VI am I train both to false data (in order to test the colored boxes).

    Thank you!

    You have a typical problem of beginner because of the lack of understanding of data flow. Run the code using execution highlighting, and look at the diagram to see.

    1. Your stop is outside any loop and so will be read only by the code only once at the beginning of the program.
    2. Your scroll bar is read in the first loop. All the other loops cannot begin until the first loop finished and since (1) is true, it will never happen if the value Boolean false when the code begins.

    Why do you have so much code duplication? 95% of the code for the loop is the same and can be reused. I don't know that the whole thing could be written using 5% of the total code. Put everything in a loop, iterate over the table 2D to get all values. Don't forget to put a little wait inside the while loop.
