How can I get a query to count a number of channels?

I want the query to count, to me, how many holidays, there are in the USA in my table. But I'm not sure how to retrieve the result of a string or varchar2 data type. That's what I've tried so far.

Select count (COUNTRYVIS) < < this column contains all the countries visited
of "IT220_HOLIDAYDETAILS" < < this is the table where the column is
where COUNTRYVIS = 'USA' < < this is the result, I want to count

ORA-00904: 'USA': invalid identifier < < this is im error message get, is there a way to count the channels?

Thanks in advance!

This has nothing to do with the APEX. Please post any fundamental questions of SQL on the + {forum: id = 75} + forum.

In any forum OTN, alll code must be posted wrapped in .

Tags as described in the FAQ:

select count(COUNTRYVIS) -- this column contains all the countries visited
from "IT220_HOLIDAYDETAILS" -- this is the table where the column is
where COUNTRYVIS = "USA" -- this is the result i want it to count

You seem to have trouble with the distinction between identifiers and literals text. Tip: Use the double quotes, other apostrophes.

Note that quoted identifiers are usually not a good idea.

  • HP Officejet Pro 8610: How can I get a report with the total number of pages printed on my HP Officejet Pro 8610?

    The number of pages that print is so critical to a choice to use the "HP Instant ink Plan' or not, how can I find the total number of pages that I printed on my brand new (installed 2 days ago) 8610?  And if I can, there are a total of 'resettable' or working capital?  Don't see anything in the user guide and a search gives nothing usable on this blog.

    Wireless printer installed on an old PC with Windows XP SP3.  I also of course install with cable network but so far it works well on my home network without a network cable.  Is there any operating system, I also have a laptop Lenovo Vista on which I can install this printer.

    Please do not answer I can find total by counting the number of pieces of paper that I have.  Surely the inner workings of this beautiful machine must have the requested data as well as HP can say my consumption if I select the monthly plan of ink!

    This 8610 was a good buy (net $89,00 after the resumption of my six years, Deskjet J36xx) at Office Depot/Max who has of course influenced my decision to purchase.  So far, I am very happy with the print quality and speed, have not yet tried the scanner and will probably never use the fax machine since I have no land line phone.

  • How can I get several hyperlinks to display in the query output?

    I uses two tables to list all a school sport teams. The table of sport lists all team data aggregated by gender. The second table uses the sportID of the first table to associate a team calendar.  The problem is not all the teams do not have a calendar.

    I'm trying to post a link to these teams with schedules. I compare the two tables, the sport and the calendar and a CFIF statement allows to compare the 2 sportIDs in the output to determine the teams who have a schedule.  If the two sportIDs corresponds to a hyperlink is displayed.

    Unfortuanetely, only one link will be displayed, even if there should be three links. Here is my code:

    Table to display aggregated by gender teams

    "< name cfquery ="getSports"datasource =" #application.database # "" >

    Choose between the sexes, team, levels, sportID

    sports

    Group sex, team, levels, sportID

    < / cfquery >

    Table used for the sportID of already created calendars

    < name cfquery = "getID" datasource = "#application.database #" >

    Select sportID

    annexes

    SportID group

    < / cfquery >

    I then compare the sportIDs and if they match, I then display a hyperlink

    "< cfoutput query ="getSports"group 'sex' = >"

    < h1 "> teams #gender < / h1 >"

    < ul >

    < cfoutput >

    < li >

    < cfif getID.sportID EQ getSports.sportID > <a href = "teams.cfm? sportID = #sportID #" >< / cfif >

    #team # < cfif levels GT "" >(#levels#) < / cfif > //levels is used to differentiate the J.V. and Varsity. "." Usage levels not all of the teams

    < cfif getID.sportID EQ getSports.sportID > </ a >< / cfif >

    < /li >

    < / cfoutput >

    < /ul >

    < / cfoutput >

    How can I get the other teams to display their links?

    Thank you gentlemen, since everyone was suggesting an outer join, I took out my trusty Manual of ColdFusion and learn about them. I've added the sum() for the query:

    Select sports.gender, sports.team, sports.levels, sports.sportID, sum (schedules.sportID) AS expected

    sports

    opening hours of the outer join left on sports.sportID = schedules.sportID

    Group of sports.gender, sports.team, sports.levels, sports.sportID

    So add the following to the output:

    And everything works perfectly. Once again, life is beautiful!

  • How can I get a name of table 1, column A, if column B is a negative number and insert the names of table 2?

    How can I get a name of table 1, column A, if column B is a negative number and insert the names of table 2?

    What is the formula?

    You can do this with a column of "index" in table 1, as this assistance:

    The formula in C2, filled to the bottom:

    IF (B =<>

    That increments a counter each time that it finds a negative number in column B.

    In the second table, you can retrieve a list of negative values in this way:

    The formula in A2, filled to the bottom:

    = INDEX (array 1::A, CORRESPONDENCE (LINE (−1, Table 1::C), 0))

    It takes the line number, the formula is activated, subtracts 1 to the header line and look up the result in the column of table 1 C.  If it finds a match, it feeds the line number to the INDEX page with retrieves the value of the column of table 1A.

    To hide the red triangles of signage wrap the IFERROR formula, like this:

    = SIERREUR (INDEX (table 1::A, CORRESPONDENCE (LINE (−1, Table 1::C), 0)),"")

    Of course, you can also simply filter on column B without the need to set up a column from another table or index.

  • How can I get the USB-Quad08 with Dasylab encoder channel data

    Hello

    I'm reading the pulse signal of USB-Quad08 with Dasylab V10, but every time I got the error message "this Committee has no meter 9513.

    I have configured the jury with Instacal and the test hardware is ok. I used the module 'Entry meter' (Modules--> inputs / outputs--> MCC - DAQ--> Counter Input) to read the signal of the channel meter. "Entry 9513 counter" displayed and I na not change settings. After connecting a graphic recorder module I run the application. The error message appeared.

    I noticed that USB-Quad08 Council has counter 9513. But why the error occurs?  How can I get his channel encoder signal?

    PS. I can get with Dasylab DIO signals, but I can't any signal with TracerDAQ, even I can't find USB-Quad08 in his list of DAQ devices.

    Please contact Measurement Computing.

  • How can I get the digital power meter?

    How can I get the digital power meter?

    I use a method similar to the example below to measure the market factor using the inputs of a multifunction data acquisition meter.  If the duty cycle is 0% or 100% for a given period, DAQ reading times out and returns an error.  In this case, I would get the digital state of the counter of entry so I can put as cycle to 0% or 100%.  I want to do it without knowing the digital port and line the entrance of counter... for example I would like to continue referencing DAQ/ctrX since I already have this information.

    The application uses an M series: PXI-6229 DAQ and LabVIEW 2011 to make a system customized for VeriStand.

    https://decibel.NI.com/content/docs/doc-12396

    For the moment I wired the block diagram to add a case structure to check the meter ID and string constants to set the identifier of digital input, as they share the physical connection.  As much as I can say that makes the specific code for the PXI-6229 (or any DAQ with only two counters that share connections with p2.1 and p) 1.4

    I have attached the VI sub.

    When the device is used with a different data acquisition, I can add the connection and/or separate control.  Looks like at least one will be necessary given that the meter can only detect the edges... I think it was the piece of information I needed.

    Thanks for your help!

  • How can I get my Photo, library etc to open?

    When I click on start, then on picture library and others, it does nothing. When I right click on image lib and then choose open, nothing happens.  How can I get the lib to open?

    Hi Henryjd,

    Thanks for posting your query in the Microsoft Community Forums.

    I see that you are unable to open the photo and the library on the computer. I would appreciate if you can help me with the following information.

    1. what version of Windows you are using on the computer?

    2. don't you make changes on the computer before this problem?

    Start the computer in safe mode and check if the problem persists, if the question does not persist then perform the clean boot and check if the problem resolves.

     

    Step 1

    Safe mode starts Windows with a limited set of files and drivers. Startup programs do not work in safe mode, and only the basic drivers needed to start Windows are installed. Please click the below mentioned link.

    http://Windows.Microsoft.com/en-us/Windows7/start-your-computer-in-safe-mode

    Step 2

    To help resolve the error and other messages, you can start Windows by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

    http://support.Microsoft.com/kb/929135

    Note: follow step 3 to reset the computer to start as usual after the boot process.

    It will be useful.

    Let us know if you encounter problems with Windows in the future. We will be happy to help you.
