Using count to count the number of occurrences of a primary key

Hi,
I'm relatively new to T-SQL and more of a SAS guy.
I just need to some help.
I have a table
CF_ID    Name
4444     Mark
4444    Mark
3321   Sarah 
All i want to do add in a new column to count the number of occurrence of the CF_ID. So my new table would be:
CF_ID    Name     New_column
4444     Mark       1
4444     Mark       2
3321     Sarah     1 
Any help would be gratefully appreciated.
Thank you
Umar Javed

Hello Umar,
You can use the
ROW_NUMBER (Transact-SQL) for this:
SELECT *, ROW_NUMBER() OVER (PARTITION BY CF_ID ORDER BY Name) AS New_Column
FROM yourTable

  • How do I count the number of occurrences of a string within a group of cells?

    Hello all, I'm trying to figure out how to count the number of times a child has completed certain tasks.  Here is a sample of the data (it is highly simplified here, but contains what I hope is needed to answer my question):
    Unnamed Table
    Objective
    John
    Ann
    Alex
    Dave
    Eric
    20a 20b 20c
    x
    20a 20b 20c
    x
    20a 20b 20c
    x
    x
    19b 20a
          x
           x
    20c 21b 22
         x
    What I am trying to do is count the number of times each child completed each objective - but I can't figure out how to go about splicing up the "objectives" fields for counting while still being able to compare them to whether or not the "child" has 'an x in the box' in that particular row.

    If I read your example correctly, John's counts should be 2 for 20a, 1 for 19b, 20b and 20c, and 0 for any other objectives listed.
    Here's an example that will work for your data set, assuming that any objective ma occur only once in each row of column A of the Main table. I've added an a to objective 22, but I think it is unnecessary, provided there is no objective 122, 221, etc.
    This uses a two step process.
    The table AUX extracts the objectives completed by each student, using the checkboxes in Main. Note that it also adds a space at the beginning and end of each string. This provides an extra character before the first objective code and after the last objective code in that row, used by the wildcard specification in the formula in the Summary table.
    Formula:
    Aux::B2: =IF(OFFSET(Data :: $A$1,ROW()-1,COLUMN()-1)," "&OFFSET(Data :: $A$1,ROW()-1,0)&" ","")
    Fill right to the last column and down to the last row of Aux.
    Summary uses COUNTIF to count the number of occurrences of each of the objectives listed in column A of that table.
    Formula:
    Summary::B2: =COUNTIF(Aux :: B,"=*"&$A2&"*")
    Fill right and down as the previous formula.

  • SSRS- Counting the number of occurrences

    Hi,
    I have table 1 filled with numbers 1-5. I need to count the number of occurrences for each number in table 2.
    For example,
    Table 1
    3
    4
    5
    4
    3
    Table 2 1-- 0 occurrences 
    2-- 0 occurrences

     5-- 1  occurrences
    Can I do this in a SSRS report?
    Thank you in advance!

    Hi Rebecca07,
    After testing the issue in my local environment, we can refer to the steps below to achieve your requirement:
    Drag a table from Toolbox to design surface.
    Delete the detail row (second row) and the third column.
    Right-click the first row to insert five rows after that row.
    Type the following expressions in each cell:
    numbers             occurrences
    1                        =count(iif(Fields!number.Value=1,1,nothing))
    2                        =count(iif(Fields!number.Value=2,1,nothing))
    3                        =count(iif(Fields!number.Value=3,1,nothing))
    4                        =count(iif(Fields!number.Value=4,1,nothing))
    5                        =count(iif(Fields!number.Value=5,1,nothing))

  • 'COUNT' the number of occurrences of a characteristic in BEx

    Good day all.
    3.x BEX.
    I want to count all the occurrences of a " Claim Number" in a BEx query.
    The u201CClaim numberu201D might have several u201Clinesu201D ie : Claim number u201CMMC123u201D has line 1, 2 and 3. I only want to count it as u20181u2019 Dealer claim number, not u20183u2019.
    I have a InfoObject "Counter" in DSO and transformation that counts all the lines, not just the claim numbers. If I set the counteru2019s key figure properties (calculate single value as..) to u2018minimumu2019, I will receive the correct quantity of lines when u201Cclaim numberu201D is displayed in the query results. BUT, I only want to display the total in the query (no detail).
    If I remove the Dealer claim number from the result, then the total displayed includes all the lines for the claim number as well.
    How do I get the correct quantity to display?
    Thanks in advance.

    Hi,
    Use exception aggregation for Keyfigure (counter) Properties with referce to the char Claim Number.
    Goto->Counter(KF)Properties->exception aggregationTab-->select refchar(Claim Number)-->ok.
    then u will get aggregation value.
    Hope it willhelp.

  • Count the number of unique values in column

    Hi
    I have a large numbers file (thousands of rows) with data for different dates. I need to calculate the number of unique (distinct) dates are in the spreadsheet.
    Does anyone know how to do this?
    Thanks,
    Bruce

    bpj,
    Let's say your date is in column B for this example and your first data row is Row 2. In another column you can enter into row 2: =IF(COUNTIF($B$2:B2, B)=1, 1, "") Summing the new column content will yield the number if unique dates.
    As badunit observes, this will result in sluggish document. If the number of possible dates is small compared to the number of rows of data, it would be better to make a table of possible dates and count the number of occurrences of each of those dates in the data, a COUNTIF function on the frequency data for the date range will give you the number of unique dates, possible much more efficiently.

  • Count the number of days in the selected range using Customer exit

    Hi Experts,
    we have requirment where user is asking to add a column to report, which will have 'count of days for which key figure is having values' for each of the months and the Header would be 'Day Count'
    Please let me know if its possible using Customer exit?

    Hi,
    In our report we have two characteristics site no. and product and we have 6 key figures of type quantity and Input for the report is Fiscal year/period
    So in the report Key figures are populated with values for respective site no. and product combination
    Now the user wants new column in report which will have header u2018Day countu2019 and it should Simply count the number of days in the selected range that have a volume different than 0 for key figure

  • Count the number of times a character is in a string using pl/sql

    I need to count the number of times ":" appers in the string ":XXX:CCC:BBB:".
    I have sound some solution using SQL but I do not want the context switch.
    Also I am on 10g so I can not use REGEXP_COUNT.
    Any help would be great.

    Hi,
    length(REGEXP_REPLACE(':XXX:CCC:BBB:','[[:alnum:]]'))counts all kinds of punctuation, spaces, etc., not just colons. Change any (or all) of the colons to periods and it will still return 4. Use '[^:]' instead of '[[:alnum:]]' if you really want to count just colons.
    Also, "SELECT ... FROM dual" is usually needed only in SQL*Plus or similar front end tools. In PL/SQL, you can call functions without a query, like this:
    x := NVL (LENGTH (REGEXP_REPLACE (txt, '[^:]')), 0);

  • Count the number of seeds using labview - new to labview

    hello,
    I am new to labview and need to create a VI to count the number of seeds being dropped.
    I understand you can do this using labview.
    please can someone direct me to a tutorial or an example to do this?
    I use a camera - how do you connect up the camera to work with labview?
    thanks

    You'll have to use IMAQ vision, an addon package that brings LabVIEW a series of tools for image analysis.
    There are a number of examples/solutions. Some deal already with particle counting.
    Although your question is rather vague, I suppose you want to get more info tahn the mere particle number (shape, color). That's definitely possible with LabVIEW, but will require a significant investment.
    There is a forum dedicated to Machine Vision where you'll get all the required help.

  • Count the number of cells used in a formula

    Is it possible to count the number of cells used in a formula?
    For example the following formula: "=Tabel 1 :: D45+D8+F7"
    The answer needed is 3

    From your description, it appears you could use SUMIF to get the totals.
    It's not necessary to know the number of times a name appears in the list to determine the sum of the numbers in the cell to the right, but if you have a separate need for that count, then COUNTIF will do the job.
    As the names may appear in more than one column, you'll need to use one iteration of the formula for each pair of columns containing name and associated number. In your description, there are names in columns C and E, with associated values in D and F respectively, and all of these cells are in the same table (which I'll name Table 1). I would calculate the totals on a second table (Table 2) containing a list of all of the names in column A, starting at A2, the COUNT of times each name is listed in column B, and the sum of the values in cells immeditely to the right of each name in column C.
    Table 2::B2: =SUM(COUNTIF(Table 1::C,A),COUNTIF(Table 1::E,A))
    Table 2::C2: =SUM(SUMIF(Table 1 :: C,A,Table 1 :: D),SUMIF(Table 1 :: E,A,Table 1 :: F))
    Select cells B2 and C2, then fill the formulas down each column.

  • How to use counters of PCI 6251 to count the number of pulses

    Hello,
    I have inputs from an optical encoder {pulse train} and i need to count the number of pulses for a short period of time to estimate the speed of the DC motor. Could you please tell me how to use the counters in PCI 6251 DAQ. I found something on DAQ STC, whichs says the input pulse should be connected to PF0 {ctr source}, but i have query where do i get the output {number of pulses counted in a particular period of time}.
    Looking for your reply.
    Thanks & Regards,
    bsnr

    Hi bsnr,
    Thanks for the post!
    In MAX (Measurement and Automation Explorer), if you find the device (DAQmx devices) and right-click, you can select pinouts - which should contain a table telling you which pins are what PFI lines.
    Then, in labVIEW, you need to generate some code to use the choosen coutner in a task to count digital edges. If your not sure on this, go to Help>>Find Examples>>Hardware I/O>>DAQmx>>Counters.. and take a look at some of the code provide.
    ps. It seems (maybe just your wording), but your expecting the counter output pin to provide the number of counted edges - this isn't the case.  
    Please let me know what you think?

  • Can i count the number of Mondays in a specific month with a formula?

    Hi
    I am looking for a streamlined way of calculating an amount to invoice for a job that I am paid for weekly, but for which I invoice monthly, meaning that I am invoicing different amounts each month, depending on how many Mondays fall in a given month (i.e. 4 or 5).
    So I am wondering if there is a function I can use to calculate the number of Mondays in a given month automatically and then I can use this value to multiply by my weekly charge to calculate the amount to invoice each month.
    Thanks

    Responses below apply to my earlier post.

    1. What part of the formula do I need to change to do the same for other days of the week, and for other years?
    No change for other years, as the full date is entered.
    I haven't looked at changes necessary to the version above to show results for other days. See below for a new table that does all days.
    2. Would it be possible to construct one table with the calendar for a whole year, which would generate a count for each day of the week, which I could then use as and when needed? Or would it make more sense to construct a separate table for each day of the week (as I am referring to in question 1)?
    Depends what information you need.
    If you need the count for only one week day, then a table showing only the count for that day of week will avoid having to search it out.
    If you need the number of occurrences of each weekday in each month, then a table showing those, with or without an attached calendar, is in order.
    Here's one that shows the count of each weekday for each month. It uses two formulas, derived from the earlier posts by Yvan and Jerry:
    B1: =DATE($A,COLUMN()-1,1)
    B2: =IF(AND(DAY(EOMONTH(B$1,0))>28,MOD(WEEKDAY(EOMONTH(B$1,0))+7-(ROW()-1),7)<(DAY( EOMONTH(B$1,0))-28)),5,4)
    The formula in B1 is filled right to M1, and the cells are formatted to show only the Month and Year. Note that the cells actually contain Date and Time values, which are used in the second formula's calculations.
    The formula in B2 is filled right to M2 and Down to M8.
    Day names in column A are entered directly and are not used in the calculations.
    The 4 digit year number is entered directly in A1. Change this number to change the year.

  • How to count the number of occurences of a character

    hi
    wat command is used to count the number of occurences of a charcter in a line?
    i have to count the number of '.' in a line

    FIND
    Searches for patterns.
    Syntax
    FIND <p> IN [SECTION OFFSET <off> LENGTH <len> OF] <text>
                [IGNORING CASE|RESPECTING CASE]
                [IN BYTE MODE|IN CHARACTER MODE]
                [MATCH OFFSET <o>] [MATCH LENGTH <l>].
    The system searches the field <text> for the pattern <p>. The SECTION OFFSET <off> LENGTH <len> OF addition tells the system to search only from the <off> position in the length <len>. IGNORING CASE or RESPECTING CASE (default) specifies whether the search is to be case-sensitive. In Unicode programs, you must specify whether the statement is a character or byte operation, using the IN BYTE MODE or IN CHARACTER MODE (default) additions. The MATCH OFFSET and MATCH LENGTH additions set the offset of the first occurrence and length of the search string in the fields <p> and <l>.

  • Is there a way to count the number of times an array moves from positive to negative?

    I have an array of values, and I need to find the number of times that the array changes signs (from positive to negative, or vice versa). In other words from a graphical standpoint, how many times a certain line crosses the x-axis. Counting the number of times the array equals zero does not help however, because the array does not always equal exactly zero when it crosses the axis (ie, the points could move from .1 to -.1).
    Thanks for you help. Feel free to email me at [email protected] I only have lv 5.1.1 so if you attach any files, they cannot be version 6.0.

    Attached is a VI showing the # of Pos and Neg numbers in an array, with 0 considered as non-Pos. It is easily modifiable to other parameters - including using the X-axis value as your compare point versus only Zero.
    This is a modified VI from LV (Separate Array.vi)
    Compare this with your other responses to find the best fit.

  • How do I count the number of records returned in the CMIS query

    How do I count the number of records returned in the query CMIS?
    SELECT COUNT(*) FROM ora:t:IDC:GlobalProfile WHERE ora:p:xRegionDefinition = \'RD_PROJETOS_EXCLUSIVOS\''}
    Euler Homero

    Hi Euler,
    interestingly enough, the reference guide for CMIS ( http://wiki.alfresco.com/wiki/CMIS_Query_Language ) that I found does not mention the COUNT function at all. On the other hand it states that: "The SELECT clause identifies which virtual columns to return in the result set. It can be either a comma-separated list of one or more queryNames of properties that are defined by queryable object types or * for all virtual columns."
    There are, however, some other posts like e.g. http://alfrescoshare.wordpress.com/2010/01/20/count-the-total-number-of-documents-in-alfresco-using-sql/ which state that they could make it working.
    Having asked in the WebCenter Portal forum, I assume that your content repository is WebCenter Content. The CMIS doc for the Content is available here: http://docs.oracle.com/cd/E23943_01/doc.1111/e15813.pdf (no COUNT there either). It does, however, mention explicitly that "CMIS queries return a Result Set where each Entry object will contain only the properties that were specified in the query.". This means your could rather investigate the Result Set. Note that there are also other means than CMIS how to get the requested result set (e.g. calling a search service directly via so-called RIDC).
    In the given context I am also interested what your use case is. OOTB CMIS in WebCenter Portal is used, for instance, in Content Presenter, where it is content rather than "parameters" what's displayed.
