FetchXML and Aggregate Functions (multiple datasets if necessary)

In fetch xml,
How do I do conduct aggregate functions (most recent, sum, average) on retrieved columns, based on matches with another column.
let's say column a has a value of "Timothy."
How do I then find the total number of column b that also have a value of 'Timothy?'
But then the next value of column a is 'John.'
I would then want to display the total number of column b that have a value of 'John?'
If this is totally impossible, could introducing another dataset help?
Sql is not available here and fetchxml can only do so much.  So this is going to have to be done with variables in the actual report.

  • Analytic function and aggregate function

    What are analytic function and aggregate function. What is difference between them?

    hi,
    Analytic Functions :----------
    Analytic functions compute an aggregate value based on a group of rows. They differ from aggregate functions in that they return multiple rows for each group. The group of rows is called a window and is defined by the analytic_clause. For each row, a sliding window of rows is defined. The window determines the range of rows used to perform the calculations for the current row. Window sizes can be based on either a physical number of rows or a logical interval such as time.
    Analytic functions are the last set of operations performed in a query except for the final ORDER BY clause. All joins and all WHERE, GROUP BY, and HAVING clauses are completed before the analytic functions are processed. Therefore, analytic functions can appear only in the select list or ORDER BY clause.
    Analytic functions are commonly used to compute cumulative, moving, centered, and reporting aggregates.
    Aggregate Functions :----------
    Aggregate functions return a single result row based on groups of rows, rather than on single rows. Aggregate functions can appear in select lists and in ORDER BY and HAVING clauses. They are commonly used with the GROUP BY clause in a SELECT statement, where Oracle Database divides the rows of a queried table or view into groups. In a query containing a GROUP BY clause, the elements of the select list can be aggregate functions, GROUP BY expressions, constants, or expressions involving one of these. Oracle applies the aggregate functions to each group of rows and returns a single result row for each group.
    If you omit the GROUP BY clause, then Oracle applies aggregate functions in the select list to all the rows in the queried table or view. You use aggregate functions in the HAVING clause to eliminate groups from the output based on the results of the aggregate functions, rather than on the values of the individual rows of the queried table or view.
    let me know if you are feeling any problem in understanding.
    thanks.

  • Any difference between distinct and aggregate function in sql query cost???

    Hi,
    I have executed many sql stmts patterns- such as:
    a) using a single table
    b) using two tables, using simple joins or outer joins
    but i have not noticed any difference in sql stmts in cost and in execution plan....
    Anyway, my colleague insists on that using aggregate function is less costly compared to
    distinct....(something i have not confirmed, that's why i beleive that they are exactly the same...)
    For the above reffered 1st sql pattern.. we could for example use
    select distinct deptno
    from emp
    select count(*), deptno
    from emp
    group by deptno select distinct owner, object_type from all_objects
    select count(*), owner, object_type from all_objects
    group by owner, object_typeHave you found any difference between the two ever...????
    Note: I use Ora DB 10g v2.
    Thank you,
    Sim

    distinct and aggregate function are for different uses and may give same result but if u r using aggregate function to get distinct records, it will be expensive...
    ex
    select distinct deptno from scott.dept;

  • Self Join and Aggregate Functions

    Hi all,
    I am trying a query in TOAD where I need to use an aggregate function MAX and a self join using a subquery. Its working fine when there is no aggregate function but when I tried to use the MAX function then its running for infi time. Is it because of the invalid joins? or because of the usage of the self join and aggregate func?
    The query contains some other tables too....
    Any one please help....
    Thanks in advance,
    G

    Toad will bring back a limited set of rows and present them to you giving the impression that the work is done. Adding an aggregate function requires the entire resultset to be traversed.
    Yes, post the 2 queries to verify what I am saying.

  • SQL query using Group by and Aggregate function

    Hi All,
    I need your help in writing an SQL query to achieve the following.
    Scenario:
    I have table with 3 Columns. There are 3 possible values for col3 - Success, Failure & Error.
    Now I need a query which can give me the summary counts for distinct values of col3 for each GROUP BY of col1 and col2 values. When there are no values for col3 then it should return ZERO count.
    Example Data:
    Col1 Col2 Col3
    abc 01 success
    abc 02 success
    abc 01 success
    abc 01 Failure
    abc 01 Error
    abc 02 Failure
    abc 03 Error
    xyz 07 Failure
    Required Output:
    c1 c2 s_cnt F_cnt E_cnt (Heading)
    abc 01 2 1 1
    abc 02 1 1 0
    abc 03 0 0 1
    xyz 07 0 1 0
    s_cnt = Success count; F_cnt = Failure count; E_cnt = Error count
    Please note that the output should have 5 columns with col1, col2, group by (col1,col2)count(success), group by (col1,col2)count(failure), group by (col1,col2)count(error)
    and where ever there are NO ROWS then it should return ZERO.
    Thanks in advance.

  • Crystal Reports and connecting to multiple tables in a dataset - I'm Going Crazy!!

    This is my first application, first report and first everything.  Wouldn't you know the report I am trying to produce is probably more difficult!!  What is happening is that I have a form(screen) up in my application with the information displayed on it from a recrod in a table that I want to put on a report to be view and/or printed and eventually down the road I want to incorporate a signature.  One step at a time though, here is what I have accomplished.  I have created the report, I have gotten it to display in the viewer but it will not push the data from the table that I want displayed.  It only displays the text that I have typed on the form.  This is a Visual Basic application created in Visual Studio 2005 using a SQL database.  If you need more information then just ask and I will try to fumble through and tell you what I know.  (Oh and to top it off............I am also trying to get information to display from other tables also (codes connected to descriptions etc.))
    Any help would be really appreciated as I have went through tutorials, read white papers, tech notes and anything else I can find but I just can't get it to work!!
    Thanks!

    You do need to give more information. To better help, we would need to know the database, when you say SQL do you mean SQL Server, how you created the dataset, whether there are multiple tables in a single dataset or multiple datasets, etc.
    The report appears to be running so the underlying issue as you know will likely be the dataset. You may want to confirm the dataset does in fact have data in it.  Returning a simple count will let you know there are rows. If you used the components rather than code to create the objects you can also see the data returned in the fill process.
    Once you know you have data in the dataset, you can check your reports connection to the dataset.
    Just hang in there... the problem is probably a simple fix. I am sure others will follow on with more suggestions.

  • Database Aggregate Functions and Oracle Discoverer

    Hello Guys.
    There are a lot of aggregate function inside the database, unfortunatelly some of them are not directly accesible from Oracle Discoverer.
    For example :
    STATS_BINOMIAL_TEST
    STATS_CROSSTAB
    STATS_F_TEST
    STATS_KS_TEST
    STATS_MODE
    STATS_MW_TEST
    STATS_ONE_WAY_ANOVA
    STATS_T_TEST_*
    STATS_WSR_TEST
    What is the best way to incorporate this kind of function in Oracle Discoverer ?
    Thanks

    While Discoverer today is unable to recognize these Oracle Database functions, we are looking at adding this capability into the product. If you think this is important, please take the poll at http://oraclebi.blogspot.com/2006/04/must-have-in-discoverer.html
    Also, if you can spare a few minutes, do send me a mail at abhinav.oracle at gmail.com with a brief description of a use case that describes where and how these functions would be used.

  • Selecting both a aggregate function and another field

    I am trying to do something very simple but I am not sure of the syntax.
    I would like to select all of the petid's and find the count of the pets in a given city, both from the same table, Pets.
    Can somebody please help me with this?
    Thanks

    Hi,
    An aggregate function will give you one row of output per group.
    For example, if you use the aggregate COUNT function to get the total number of rows in a whole table, then you can only have one row of output, representing the whole table, so, if I understand the problem, you can't (easily) use an aggregate function.
    Almost all of the aggregate functions have analytic counterparts, that can produce the same results without collapsing the result set into one row per group.
    I think this is what you requested:
    SELECT  petid
    ,       COUNT (*) OVER (PARTITION BY 1)  AS total_cnt
    FROM    pets
    WHERE   city    = 'Paris'  -- or whatever
    ;Sorry, I'm not at a database now, so I can't check, but I think you don't need the PARTITION BY clause, so you can also say:
    ,       COUNT (*) OVER ()  AS total_cntThe keyword OVER marks this as an analytic, rather than an aggregate, function.
