SUM Of Report Field With Expression Which Has COUNT Aggregate Function
Hi everyone,
I have created a report which has 3 groups. The report output as shown below. I am having trouble getting the SUM of Total Credtis for each Org.
Can't seem to get the total 42 and 16 (highlighted), but can get total unists 11 and 13. I get expression contains aggregate function. This is because Units assessed is the Count of IDs (details hidden from the report).
Report has three groups Org , Assessor and Unit.
Can someone please help me with this?
Appreciate help.
Thank you,
Ski
Org 1(Group1)
Unit Credits Units Assessed(# of Trainees) TotalCredits
Assessor 1 Unit 1 2 4 (Count of Ids) 8 (2*4)
Assessor 2 Unit 2 1 2 2 (1*2)
Assessor 3 Unit 3 5 2 10 (5*2)
Unit 4 2 1 2
Assessor 4 Unit 5 10 2 20
--------------------------------------------------------------------------------------------------------
11 42 -----------------------------------------------------------------------------------------------------------
Org 2
Assessor 3 Unit 1 2 3 6
Assessor 4 Unit 6 1 10 10

COunt Function In Report
I am creating a report that will print the customer's Invoices grouped by SalesPerson. I created a variable in the dataset so that it sets to the status of the invoce to Paid, Not Paid and Partial. All is working fine so far. I have a groupfooter for each salesperson where I want to print the total no. of invoices for that SalesPerson that are PAID, NONPAID and Partaial. So on the expressions of that fields, I have the following code. It allows me to print the report, but it prints #Error for the value of thoses field I also want to print the the same fields in the report total area. Any ideas ?? =Count(Fields!Document_No_.Value)having (Fields!InvStatus.Value = "PAID") =Count(Fields!Document_No_.Value)having (Fields!InvStatus.Value = "UNPAID") =Count(Fields!Document_No_.Value)having (Fields!InvStatus.Value = "PARTIAL")

COUNT Occurrences Of Value In Aggregate Query
I have a table as below: COMPUTERNAME, COUNTER, REASON WXP-13Failed WXP-1113Failed WXP-38Failed WXP-910Failed WXP-117Success What I would like to do is create a percentage of Success vs. the Failed for the same Computername. Problem is when I use Group by I cannot tell the COUNTER of the Success anymore. This is what I have been using: SELECT COMPUTERNAME, SUM(COUNTER) AS COUNTERTOTAL FROM ReturnTable GROUP BY COMPUTERNAME Thank you. The above query actually targets a result table from another query, but that should not matter.

Assign Aggregate Count Results To Variable
I have an aggregate transform that outputs two columns, a group by (DT_STR) and a count(column name) (DT_UI8). The results are put into a Recordset Destination. When I attempt to map these columns to variables in a Foreach Loop Container (using a Foreach ADO Enumerator), I get the error: Error: 0xC001F009 at ExtractNNRPersonUpdates: The type of the value being assigned to variable "User::NNRPersonCount" differs from the current variable type. Variables may not change type during execution. Variable types are strict, except for variables of type Object. Error: 0xC001C012 at Foreach Household Loop Container: ForEach Variable Mapping number 2 to variable "User::NNRPersonCount" cannot be applied. The variable mentioned in the error message is setup as a UInt64. I've tried all other integer data types and nothing works. I also tried changing the data type of the count coming out of the Aggregate transform but received a warning stating this isn't possible. Any idea what I may be doing wrong?

Using Aggregate Function
I want to use the Aggregate function in Reporting services for a drilldown report. The field to be aggregated is a Percentage field. It is based on an analysis services datasource There are 3 groups for the drilldown Company -> Branch -> Employee The detail level has the individual sales The lowermost group 'Employee' shows the percentage sales for each employee The next level 'Branch ' shows the percenatge sales for all employees in that branch The uppermost level 'Company' shows the percentage sales for all branches in the company When I try to give the scope for the aggregate function at the 'Branch' level it fails Aggregate(Fields!TAT_Percent.Value,"grp_Employee") Aggregate(Fields!TAT_Percent.Value,"grp_Sales_Details") where grp_Employee is the name of the Employee grouping and grp_Sales_Details is the name of the details group I get the error "The scope parameter must be the name of a scope where all containing grouping scopes have group expressions which are simple field references" I have tried the aggregate function without scope and that too doesnt work. What am I doing wrong? .

Single Value From An Aggregate Function
Hey everyone, I'm looking for a way to insert a count of a set of records into a table and then read that table and produce an XML file from that dataset. The problem that I'm coming across is that when you do this type of query you have to specify one of the values from the table and then get a count for the number of records of that particular range of values. The table that I am trying to get the data from will look something like this: ItemID ModuleID Description ......1 2869 blah blah blah2 2869 blah blah blah3 2869 blah blah blah4 2690 bit bit bit5 2690 bit bit bit6 2690 bit bit bit So I count the 2869's and 2690's and place the ModuleID and the count of the ItemID's in another table. Then I need to extract the data from the table and put it into an XML file that is readable by the ReadXML method in ASP.NET. So far I've got the SPROC to do only one record at a time but I would like one that does the whole table rather than one at a time using a parameter.

Aggregate Function "aggrevating Me!!!"
Hello folks, I am trying to do a simple query on SQL 7.0 using sql query analyzer on a hugh db. Here is the query: select logid,count(logid) from tablename group by logid order by logid desc compute sum(count(logid)) The results should be a large number say 10471066...and what am I getting 104710 yeap the last two digits got truncated. Now I know that I should get 10471066 because I also queried with count(*) and count(logid) without compute and numbers are same. Interestingly when I use rollup it gives me the numbers I am expecting. select logid,count(logid) group by logid with rollup order by logid desc This mystery is driving me crazy. What is it that I am doing wrong with compute or am I missing something. Any and all help or hints are appreciated. Thanks in advance...I'll get a good night sleep else this problem will keep daunting me.... HP

Aggregate Function Trouble
Problem 1: Suppose I have a table T( A, B, C, D, E ) I want to retrieve D, E for all rows which have minimum C when we do a group by on A and B. The query would look something like SELECT D, E FROM T HAVING C = MIN( C ) GROUP BY A, B Unfortunately, SQL server gives the error that D, E are not in a group by clause. One way is: SELECT T.D, T.E FROM T, ( SELECT A, B, MIN( C ) AS F FROM T GROUP BY A, B ) AS T1 WHERE T.A = T1.A AND T.B = T1.B AND T.C = T1.F What I want to know is whether there is a simpler way of doing this or not, kinda like the first illegal query. Problem 2: Suppose in the query SELECT A, B, CASE WHEN C = 'A' THEN 1 WHEN C = 'B' THEN 2 END ORDER I want to do MIN( ORDER ). The simple way would be SELECT A, B, MIN( CASE WHEN C = 'A' THEN 1 WHEN C = 'B'' THEN 2 END ) But this gives an error. There is a way: SELECT T.A, T.B, MIN( T.C ) FROM ( SELECT A, B, CASE WHEN C = 'A' THEN 1 WHEN C = 'B'' THEN 2 END AS C ) AS T but I want to know if there is a simpler way to do this (kinda like the first illegal query).

Aggregate Function/Join Troubles
Hey, I am running into trouble performing a second join on a column while using aggregate functions over that table. What I think is happening is that the aggregate values (sum, avg, count) are being multiplied because I am joining on the same table a second time, but I don't know how to fix or avoid this problem. Here's the query: --- SELECT CAST(ro.xing_tc_no AS INT) AS loc_id, SUM(ro.total_fatal) AS tot_fatal, SUM(ro.total_serious) AS tot_serious, SUM(ro.total_minor) AS tot_minor, COUNT(ro.report_no) AS tot_accidents, AVG(ro.NO_OCCUPANTS) AS num_occupants FROM UserHotspots uh LEFT JOIN rods_k_crossing AS rkc ON rkc.location_id = uh.CrossingID LEFT JOIN rods_occurrence AS ro ON rkc.tc_location_nbr = ro.xing_tc_no GROUP BY ro.xing_tc_no --- The second join is also performed on rods_k_crossing and that is when the sums, avgs, and counts get multiplied. If I take that second join out the numbers come out fine. Thanks for any help!

Aggregate Function - Tough Query For Me...
I currently have the following query: Quote: select distinct a.memberFirstName, a.memberLastName, c.ChapterName, d.divisionName, count(f.memberID) as numMembers FROM Members a INNER JOIN groupLeaders b ON a.memberID = b.memberID Inner JOIN Chapters c ON c.chapterID = b.chapterID LEFT JOIN divisions d ON d.divisionID = c.divisionID Inner Join groupsOfEight e ON e.groupLeaderID = b.groupLeaderID Inner Join groupOfEightMembers f ON f.groupOfEightID = e.groupOfEightID Group BY a.memberFirstName, a.memberLastName, c.chapterName, d.divisionName Order By divisionName, numMembers This query returns me the names of all of my Group Leaders, their Chapter, Division, and the number of members they have selected to be in their group. Now, instead of the number of members in each Group I would like to know the total number of Members in each division to appear in the count. [NOTE: All chapters have a division, linked by a divisionID in the "Chapters" table -- I need to get a count of all the "ChapterMembers" [chaptermembers is a table also] that are in the Division. Here is the query I started to build before I ran into serious trouble: Quote: select a.divisionName, count('c.memberID') as numMembers From Divisions a Inner Join Chapters b On b.divisionID = a.divisionID Inner Join chapterMembers c ON c.chapterID = b.chapterID Left Join Members d ON d.memberID = c.memberID LEFT Join groupLeaders e On e.memberID = d.memberID Group By a.divisionName This particular query returns only the DivisonName and the number of Members in the division as expected. However, when I try to select the information for the GroupLeader (first & last name) I am forced to add memberFirstName to the Group By statement which changes my Count... Have I done an okay job of explaining the problem? The goal here is to select all of the GroupLeaders first & last name, their chapterName, divisionName, and the total number of members in the division. Thanks for any advice! Zoop

Please help! using System; using System.Data; using Microsoft.SqlServer.Server; using System.Data.SqlTypes; using System.IO; using System.Text; [Serializable] [SqlUserDefinedAggregate( Format.UserDefined, //use clr serialization to serialize the intermediate result IsInvariantToNulls = true, //optimizer property IsInvariantToDuplicates = false, //optimizer property IsInvariantToOrder = false, //optimizer property MaxByteSize = 8000) //maximum size in bytes of persisted value ] public class Concatenate : IBinarySerialize { /// <summary> /// The variable that holds the intermediate result of the concatenation /// </summary> private StringBuilder intermediateResult; /// <summary> /// Initialize the internal data structures /// </summary> public void Init() { this.intermediateResult = new StringBuilder(); } /// <summary> /// Accumulate the next value, not if the value is null /// </summary> /// <param name="value"></param> public void Accumulate(SqlString value) { if (value.IsNull) { return; } this.intermediateResult.Append(value.Value).Append(','); /// I want to change to comma to a variable } /// <summary> /// Merge the partially computed aggregate with this aggregate. /// </summary> /// <param name="other"></param> public void Merge(Concatenate other) { this.intermediateResult.Append(other.intermediateResult); } /// <summary> /// Called at the end of aggregation, to return the results of the aggregation. /// </summary> /// <returns></returns> public SqlString Terminate() { string output = string.Empty; //delete the trailing comma, if any if (this.intermediateResult != null && this.intermediateResult.Length > 0) { output = this.intermediateResult.ToString(0, this.intermediateResult.Length - 1); } return new SqlString(output); } public void Read(BinaryReader r) { intermediateResult = new StringBuilder(r.ReadString()); } public void Write(BinaryWriter w) { w.Write(this.intermediateResult.ToString()); } }

Aggregate Function Task Issue
We have a Data Flow Task. Inside this, we have a OLE DB Data Source which calls and executes a stored procedure. We use a Row Count Task to count the number of rows returned by the OLE DB Data Dource Task. Then, we use an aggregate function task to get the sum of all the rows of one particular column that is returned from the OLE DB Data Source. The issue here is that we want to assign the sum value returned by the Aggregate Function Task to a User Variable named User::Variable. We have tried to assign this by using @User::Variable and User::Variable, but neither of those return the expected value. If there is any other method to do the same then let us know. We have checked the that the row count is greater than zero. Any help would be very much appreciated. Thanks in advance.

Aggregate Function - Group Scope
Hi There, I need to sum some group totals in higher groups. A regular sum doesn't work for this case, so I am trying to add a group scope to the sum function. =sum(Fields!GrossHours.Value,"TableRow6") =sum(Fields!GrossHours.Value,"GroupName") =sum(Fields!GrossHours.Value,"EmployeeNameGroup") I am trying to sum the value in TableRow6 (which is the group 4 header) in group 3. The name of the group in the group sorting properties dialog box is: EmployeeNameGroup. All my attempts get the same error: The value expression for the textbox has a value that is not valid for an aggregate function. The scope parameter must be set to a string constant equal to the name of a containing group, containing data region or the name of a dataset. Thanks for reading. Paul O

Aggregate Function/Ambiguous Trouble
I'm a newb and this has been giving me a trouble for a while. Code Block SELECT class.classcode, classname, instrFirst, instrLast, csDay, CONVERT(nvarchar(30), csStart, 8), CONVERT(nvarchar(30), csEnd, 8) FROM class, class_section, instructor WHERE class.classcode = class_section.classcode Group By className Order By classname, csNum; Msg 8120, Level 16, State 1, Line 1 Column 'class.classCode' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause. class and instructor and class_section are their own tables but classcode and instrID are foreign keys on the class_section table. If anyone can explain this as clearly as possible that would be great (the help examples are usually too complicated)

Cannot Perform An Aggregate Function On An Express
as a follow on from my last post, here is my sql to give the sum of all payments we have recived for a particular batch of data , dependant upon the rate. Select SUM(Case dp.ReceivedByID When 2 Then dp.PaymentAmount * (cn.DirectRate / 100) When 1 Then dp.PaymentAmount * (cn.FeeRate / 100) Else dp.PaymentAmount * ((cn.FeeRate + cn.FieldRate) / 100) End) From dbo.DebtPayment dp, dbo.ImportBatchItem bi, dbo.Debt d, dbo.Contract cn where cn.ClientContractID=d.ContractID AND d.Debtid=dp.DebtID AND dp.DebtID=bi.ItemID AND bi.ImportBatchID=101 AND cn.ClientID=1021 cn.DirectRate is the current contract rate. This rate can be changed at any time on the system. i have created a table that stores the the rate for a particulat time frame. with the sql to return ruturn the rate for a time period, client & contract like so. select cfc.ComRate from dbo.mContractFeeChange cfc where cfc.ClientID=1021 and cfc.contractid=12 and someDate >= cfc.StartDate AND someDate <= cfc.EndDate when i plum this as a sub-query into my main query as so Select SUM(Case dp.ReceivedByID When 2 Then dp.PaymentAmount * ( (select cfc.ComRate from dbo.mContractFeeChange cfc where cfc.ClientID=1021 and cfc.contractid=12 and dp.PaymentDate >= cfc.StartDate AND dp.PaymentDate <=cfc.EndDate)/ 100) When 1 Then dp.PaymentAmount * (cn.FeeRate / 100) Else dp.PaymentAmount * ((cn.FeeRate + cn.FieldRate) / 100) End) From dbo.DebtPayment dp, dbo.ImportBatchItem bi, dbo.Debt d, dbo.Contract cn where cn.ClientContractID=d.ContractID AND d.Debtid=dp.DebtID AND dp.DebtID=bi.ItemID AND bi.ImportBatchID=101 AND cn.ClientID=1021 I get the following error.
