How to determine the number of rows in the database and save the result to a local variable?

Hello

I'm a newbie in the use of TestStand, databases and SQL, and now I've met difficulties. I use TestStand 2014 (32 bit).

I have a need to know the number of rows in a database and save that number in a local variable. I tried to practice using the database of the Types of step provided with TS. I tried to use the following in a SQL statement:

Locals.NumberOfRows = ("SELECT COUNT (*) FROM TEST_TABLE")

It returns an error: specified value is not the expected type. My goal is possible in this way, or I'm doing this completely wrong?

Thank you for your response, Norbert. I have a database of who wins new values at random, and sometimes I need the exact number of rows in this table.

I managed to achieve my goal by using the SQL statement: "SELECT COUNT (*) as Rowcount OF TEST_TABLE", followed by a data GET operation, which records that number of lines in a local variable.

  • How to determine the number of highlight ' to write ' for DAQmx generate analog output?

    On the configuration of the stage for DAQmx generate analog output, there is a field "value to write.  I can't find any explanation for what it is, how it determines the value to enter, nor what he writes.  I am trying to go through the tutorials and it cling.

    Someone would give an explanation?

    Hello

    To write value specifies the value to write in the channels, lines or ports selected in string parameters. In other words, this value will be the value of your DC output (for example if you enter 5, your output will be 5V). To get information on different fields in SignalExpress, access help"context-sensitive help. A pane will appear in your work environment that displays the coordinates of the field when you place your pointer over them.

    For new users of SignalExpress:

    Generation of DC signals with NI DAQmx devices: step in the DAQmx build, select 1 sample (on request) in the generation Mode dropdown. You can select a programmatic input to generate, or you can remove the check mark from the check box use programmatic input and specify a value for generating in the field of value to write . NOR-DAQmx help also provides additional information about the data generation.

  • How to determine the ROWNUM in a Master detail form

    Hello

    I work in a master detail form with controls and information in order of points; I have created a process that allows users to select a product on a tabular presentation ID and the next column is filled automatically with the Product Description.

    To achieve this, I followed some instructions by Denes Kubicek (http://apex.oracle.com/pls/otn/f?p=31517:241), but my case is slightly different:

    < ul > I use a form tabular-created by Wizard, instead of manual tabular form; and < /ul >
    < ul > instead of using another page as a Popup to pass the parameter of the ROWNUM, I use a plugin called "tabular form Super LOV" which is a modified version of Super LOV the SkillBuilders who works on tabular forms. < /ul >

    The product ID is returned in the line by the plug-in; but in the case of the Description of the product, it is always returned in the first row; and my problem is that I don't know how to determine the line where the user clicked to call the plugin.

    I created an example in apex.oracle.com in case someone wants to look at:
    Workspace: ediazjorge
    User name: test
    Password: test
    App name: Sample App
    The app number: 1550

    BTW, I use Apex 4.1.1.00.23 and Oracle DB 10.3.2.

    Thanks in advance,

    See what {message identifier: = 10436048}

    OR

    {message: id = 10458307}

    You must use something like below

    //in your case currIndex means the ROWNUM value you have
    $('input[name="f03"]')[currIndex].val('some thing')
    

    And for the jquery selector try this

    $('img[alt="Popup Lov"]')
    
  • How to determine the amount of memory shipped on the PXI-5114

    How to determine the amount of memory onboard, I have on my PXI-5114?

    Thanks in advance.

    Hello

    I'm sorry I didn't know you already had the map.  There is a property for NO-Scope node to determine the total amount of available memory that we can then divide down to get the memory available per channel.  Please see the vi and help below:

    This gives a shot, just drop it in a VI that you use and if it should return your memory cards.  If you don't have a LabVIEW I can probably retrieve the purchased version by querying your serial number.

    Kind regards

  • How to determine the location of a Windows 7?

    I want to know how Windows 7 to locate a comphuter.

    Thank you

    There are two ways that windows can determine the location of the computer.  The most common is through the ip address.  The Ip address is assigned to the netwrok by the ISP.  You can determine the location of his similiarly IP network how to determine the place of a phone number of his area code.

    Also what you do online can casue of many sites infer you the location.  For example, if you use goolge to search a lot of things in Minneapolis, they deduce that you live in this area will serve as announcements concerning this area.

  • System tablespace allocation how oracle determines the size of the measure

    Hello

    It may be a silly question, but the I must request and obtain a few knowdge

    Assume that the allocation_type tablespace is system so how oracle determines the initial measurement and size max measure?

    Osama has provided useful links to the information you need. I'll just add with locally managed tablespace that the maximum number of spans is always unlimited even if you specify a value in the storage of declaration of establishment clause. Oracle does not take into account the value you provide and will with unlimited. I consider this unfortunate since in most cases, I know how large tables can reach and if the table extends beyond that point a developer made a mistake.
