Ok, here's the condensed form. I have three main tables to draw data from:
StudentData - PK is the student's ID Number. Contains contact info, their current status ('00' for none, 'P' for Probation, 'S' for Suspension), and cumulative gpa data.
CourseData - PK is the CRN. Contains just the abbreviated subject and the course number (IE ECON 200)
StudentCourses - PK is an AutoNum. Many-to-Many relationship table between StudentData and CourseData. Also contains stats for the particular student's class (grade, credit hours, etc).
So some sample data would look like:
-
StudentData
ID: 12345678
Name: John Doe; ...[Other contact info]; 00; CumCreditHours: 100; CumCoursePoints: 190
-
CourseData
CRN: 0001; Abbrev: ECON; CourseNumber: 101
CRN: 0002; Abbrev: CSCI; CourseNumber 201
-
StudentCourses
AutoNum: 1
StudentID: 12345678; CRN: 0001; Grade: A-; Credits: 3
AutoNum: 2
StudentID 12345678; CRN: 0002; Grade: B; Credits: 3
-
At this point, this is how I have things set up:
First, a query runs that finds all of the courses a student takes and converts the letter grades into a point value. Another query based on the first sums the point totals and the credit hours. A third query takes those totals and calculates the GPA by dividing their point total by the credit hour total.
Separately, a query runs that calculates the student's cumulative GPA by taking their cumulative points and hours from the StudentData table (again dividing the points by the hours).
Then, another query takes both the semester GPA, cumulative GPA, current status, and cumulative credit hours and calculates the recommended action for the student. So for our example data it would look like:
_
SemesterGPA: 3.33; CumulativeGPA: 1.90; CurrentStatus: 00; CumulativeCreditHours: 100
_
I have the formula to determine their recommended action set up as a series of nested IIF statements that looks like:
IIf([CurrentStatus]="00" And [CumulativeGPA]<2 And [CumulativeCreditHours]>=12 And [CumulativeCreditHours]<=23,"PFY",IIf([CurrentStatus]="00" And [CumulativeGPA]>=1.7 And [CumulativeGPA]<=1.99 And [CumulativeCreditHours]>=24,"P",IIf([CurrentStatus]="00 " And [CumulativeGPA]<2 And [SemesterGPA]<2 And [CumulativeCreditHours]<12,"W",IIf([CurrentStatus]="00" And [CumulativeGPA]>=2 And [CumulativeGPA]<=2.5 And [SemesterGPA]<2 And [CumulativeCreditHours]>=12,"WUP",IIf([CurrentStatus]="00" And [CumulativeGPA]<1.7 And [CumulativeCreditHours]>=24,"SUSP",IIf([CurrentStatus]="P" And [CumulativeGPA]<2 And [SemesterGPA]>=2 And [CumulativeCreditHours]>=12,"CP",IIf([CurrentStatus]="P" And [CumulativeGPA]>=2 And [SemesterGPA]<2 And [CumulativeCreditHours]>=12,"SPCP",IIf([CurrentStatus]="P" And [CumulativeGPA]>=2 And [CumulativeCreditHours]>=12,"RP",IIf([CurrentStatus]="P" And [CumulativeGPA]<2 And [SemesterGPA]<2 And [CumulativeCreditHours]>=12,IIf(IsNull([PriorSuspension]),"S(FD)","D(SD)"),"None")))))))))
For our example, John Doe's recommended action would be 'P' since his current status is 00, he has over 24 cumulative credits, and his cumulative gpa is between 1.7 and 1.99.
Now for the problem: I would like to be able to make a report that can filter by the recommended action. I've detailed the issues I've had previously, but in short, the way I have the reports set up now (with the information being displayed in a sub-report inside a report that is based on the StudentData table to provide the aforementioned queries with the StudentID) doesn't allow me to do this because the field I want to filter by exists in the sub-report and not the main report (and you can't set the filter properties for a sub-report).
Any ideas?
Ok, I've got this to work now. I realized that as I was calculating the semester GPAs that I had grouped the results together by ID at some point during the process. This allowed me to remove the part of the initial query that grabbed the ID number from the form. Since the last query in the process linked everything together by student ID, the individual records held all of the information I needed and everything fell into place after that.
I half expected something simple like this to be the answer to my problem, but I'm still disappointed that it took me this long to figure it out...
Anyway, thanks to anyone who might have been thinking of possible solutions for this problem.

I am working on a report to show the total number of hours an employee spent working. Our company tracks labor hours by Service Request and Work Order so I need to bring totals for each into the report.
I created two datasets- one for Work Orders and one for Service Requests. Ideally, I would like to combine the total number of Work Order hours with the total number of Service Request hours and present that number listed by employeeID since both datasets have the employeeID field.
I thought it would be as simple as:
=(SUM(Fields!TOTALHOURS_WO.Value, "DataSet1") + SUM(Fields!TOTALHOURS_SR.Value, "DataSet2"))
I don't get an error, however, I am getting a number which repeats for each employee so I know I'm doing something wrong.
Any help is greatly appreciated.
Mal,
As #StevenWhite mentioned, LOOKUP is probably the function you are looking for.
Here is an example for you. For the example datasets:
EmployeeID | TOTALHOURS_WO
-----------------------------------
123 | 12
456 | 3
EmployeeNum| TOTALHOURS_SR
-----------------------------------
123 | 2
456 | 5
You will note that each table in a SSRS report needs a DataSet assigned to it. I will assume your table is using our first DataSet, which we will name "DataSet1". The second dataset above will be "DataSet2".
For your total hours you will use an expression. It should look something like this:
=TOTALHOURS_WO + LOOKUP(Fields!EmployeeID.Value, Fields!EmployeeNum.Value, Fields!TOTALHOURS_SR.Value, "DataSet2")
So you will be adding the TOTALHOURS_WO from your local dataset to the result from the LOOKUP function. What lookup is doing is taking the first field from your local dataset, finding a match in the dataset provided to the function (as a string), and returning the field from the row it matched to. The last parameter is the dataset to search.
Just in case you get an error... it's always a good idea to cast data to the type you want to work with in case it comes in wrong. So...
=CINT(TOTALHOURS_WO) + CINT(LOOKUP(Fields!EmployeeID.Value, Fields!EmployeeNum.Value, Fields!TOTALHOURS_SR.Value, "DataSet2"))
This assumes you have a one to one match on employee ID. If you have to SUM both fields you can try this:
=SUM(CINT(TOTALHOURS_WO)) + SUM(LOOKUPSET(Fields!EmployeeID.Value, Fields!EmployeeNum.Value, CINT(Fields!TOTALHOURS_SR.Value), "DataSet2"))
SUM for TOTALHOURS_WO will give you the SUM in your current table group (so make sure you are grouping by staff ID in the table). It will then add it to the SUM of LOOKUPSET. LOOKUPSET works the same as lookup but returns an array of matches instead of the first.
Hope this helps.
I have a table with records each representing an appointment. I have the name of the contactthe appointment is with, and the date. In another table I have a field that contains how many appointments each contact is supposed to have during the day. There are 12 entries for each contact, because some are expected to have different numbers during different months.
I am able to call up the data for the appropriate contactfor the appropriate month. It looks great in the graph when I count up the number of entries for Contact A and put next to it the expected number of entries from the related table.
The problem I'm running into now is that I need to add up all of the expected appointments between all of the entities. So:
::ContactName:: ::appointments:: ::expected::
Contact A 12 10
Contact B 33 34
Contact C 18 27
Getting the roll up for the actual appointments is easy, a simple COUNT summary field in a subsubsummary section. But what of the expected? Because ContactA had 12 appointments that means that there will be 12 records for them, so putting a summary field for the expected column is would return 120 for all Contact A's. Instead, given the dataset above, I need the calculation to return 71. Does this issue make sense? Any help would be greatly appreciated.
If I am following this correctly, you need to divide the amount of expected appointments between the entries of the group, then total the result. So something like:
Sum ( Entities::Expected ) / GetSummary ( sCount ; EntityID )
(this would be easier if we knew the names of your tables and fields).
P.S. The term "entity" has a specific meaning in the context of a relational database. Consider using another term (e.g. "contacts").
Added:
Using your example data, you should see the following results in the above calculation field:
in the 1st group of 12 records: 10 / 12 = .8333333333333333
in the 2nd group of 33 records: 34 / 33 = 1.0303030303030303
in the 3rd group of 18 records: 27 / 18 = 1.5
When you sum all this up (using a summary field defined as Total of this calculation field), you should get 71 (or a number very near 71, due to rounding errors).
Note: in the above calculation, sCount is a summary field defined in the Appointments table as Count of [ any field that cannot be empty ], and EntityID is the field by which your records are sorted and grouped (and it must be a local field).
I'm fairly new to php / mysql programming and I'm having a hard time figuring out the logic for a relational database that I'm trying to build. Here's the problem:
I have different leaders who will be in charge of a store anytime between 9am and 9pm.
A customer who has visited the store can rate their experience on a scale of 1 to 5.
I'm building a site that will allow me to store the shifts that a leader worked as seen below.
When I hit submit, the site would take the data leaderName:"George", shiftTimeArray: 11am, 1pm, 6pm (from the example in the picture) and the shiftDate and send them to an SQL database.
Later, I want to be able to get the average score for a person by sending a query to mysql, retrieving all of the scores that that leader received and averaging them together. I know the code to build the forms and to perform the search. However, I'm having a hard time coming up with the logic for the tables that will relate the data. Currently, I have a mysql table called responses that contains the following fields,
leader_id
shift_date // contains the date that the leader worked
shift_time // contains the time that the leader worked
visit_date // contains the date that the survey/score was given
visit_time // contains the time that the survey/score was given
score // contains the actual score of the survey (1-5)
I enter the shifts that the leader works at the beginning of the week and then enter the survey scores in as they come in during the week.
So Here's the Question: What mysql tables and fields should I create to relate this data so that I can query a leader's name and get the average score from all of their surveys?
You want tables like:
Leader (leader_id, name, etc)
Shift (leader_id, shift_date, shift_time)
SurveyResult (visit_date, visit_time, score)
Note: omitted the surrogate primary keys for Shift and SurveyResult that I would probably include.
To query you join shifts and surveys group on leader and taking the average then jon that back to leader for a name.
The query might be something like (but I haven;t actually built it in MySQL to verify syntax)
SELECT name
,AverageScore
FROM Leader a
INNER JOIN (
SELECT leader_id
, AVG(score) AverageScore
FROM Shift
INNER JOIN
SurveyResult ON shift_date = visit_date
AND shift_time = visit_time --depends on how you are recording time what this really needs to be
GROUP BY leader ID
) b ON a.leader_id = b.leader_id
I would do the following structure:
leaders
id
name
leaders_timetabke (can be multiple per leader)
id,
leader_id
shift_datetime (I assume it stores date and hour here, minutes and seconds are always 0
survey_scores
id,
visit_datetime
score
SELECT l.id, l.name, AVG(s.score) FROM leaders l
INNER JOIN leaders_timetable lt ON lt.leader_id = l.id
INNER JOIN survey_scores s ON lt.shift_datetime=DATE_FORMAT('Y-m-d H:00:00', s.visit_datetime)
GROUP BY l.id
DATE_FORMAT here helps to cut hours and minutes from visit_datetime so that it could be matched against shift_datetime. This is MYSQL function, so if you use something else you'll need to use different function
Say you have a 'leader' who has 5 survey rows with scores 1, 2, 3, 4 and 5.
if you select all surveys from this leader, sum the survey scores and divide them by 5 (the total amount of surveys that this leader has). You will have the average, in this case 3.
(1 + 2 + 3 + 4 + 5) / 5 = 3
You wouldn't need to create any more tables or fields, you have what you need.
I have to get distinct rows sum in SSRS expression.
**StudentId TestScoreMath CurriculumEnrolled EnrollStatus**
100 200 Nursing Enrolled
100 200 Physical Enrolled
200 100 Tech Enrolled
Total Student TestScoreMath should be 300 not 400. I tried using the expression
=Sum(Fields!TestScoreMath .Value, "table1_Group3")
How can I SUM the value of TestScore of distinct students? I need this only in SSRS.
In SSRS 2005, this is not too easy. I would add embedded code to keep a running total. You can have the custom code to check to see if the current student ID matches the last. If so, then don't add another test score to the total. Or you could group by Student ID and call your custom code only in the header or footer of that group.
This sample shows totaling all rows: you'll need to add to this to track the studentID.
Hey. I have 160 columns that are filled with data when a user fills a report form out and submit it. A few of these sets of columns contain similar data, but there needs to be multiple instance of this data per record set as it may be different per instance in the report.
For example, an employee opens a case by a certain type at one point in the day, then at another point in the day they open another case of a different type. I want to create totals per user based on the values in these columns. There is one column set that I want to target right now, case type. I would like to be able to see all instances of the value "TSTO" in columns CT1, CT2, CT3... through CT20. Then have that sorted by the employee ID number, which is just one column in the table.
Any ideas? I am struggling with this one.
So far I have SELECT CT1, CT2, CT3, CT4, CT5, CT6, CT7, CT8, CT9, CT10, CT11, CT12, CT13, CT14, CT15, CT16, CT17, CT18, CT19, CT20 FROM REPORTS GROUP BY OFFICER
This will display the values of all the case type entries in a record set but I need to count them, I tried to use,
SELECT CT1, CT2, CT3, CT4, CT5, CT6, CT7, CT8, CT9, CT10, CT11, CT12, CT13, CT14, CT15, CT16, CT17, CT18, CT19, CT20 FROM REPORTS COUNT(TSTO) GROUP BY OFFICER
but it just spits an error. I am fairly new to mysql databasing and php, I feel I have a good grasp but query'ing the database and the syntax involved is a tad bit confused and/or overwhelming right now. Just gotta learn the language. I will keep looking and I have found some similar things on here but I don't understand what I am looking at (completely) and I would like to shy away from using code that "works" but I don't understand fully.
Thank you very much :)
Edit -
So this database is an activity report server for the days work for the employees. The person will often open cases during the day. These cases vary in type, and their different types are designated by a four letter convention. So your different case types could be TSTO, DOME, ASBA, etc etc. So the user will fill out their form throughout the day then submit it down to the database. That's all fine :) Now I am trying to build a page which will query the database by user request for statistics of a user's activities. So right now I am trying to generate statistics. Specifically, I want to be able to generate the statistic of, and in human terms, "HOW MANY OCCURENCES OF "USER INPUTTED CASE TYPE" ARE THERE FOR EMPLOYEEIDXXX"
So when a user submits a form they will type in this four letter case type up to 20 times in one form, there is 20 fields for this case type entry, thus there is 20 columns. So these 20 columns for case type will be in one record set, one record set is generated per report. Another column that is generated is the employeeid column, which basically identifies who generated the record set through their form.
So I would like to be able to query all 20 columns of case type, across all record sets, for a defined type of case (TSTO, DOME, ASBA, etc etc) and then group that to corresponding user(s).
So the output would look something like,
316 TSTO's for employeeid108
I hope this helps to clear it up a bit. Again I am fairly fresh to all of this so I am not the best with the vernacular and best practices etc etc...
Thanks so much :)
Edit 2 -
So to further elaborate on what I have going on, I have an HTML form that has 164 fields. Each of these fields ultimately puts a value into a column in a single record set in my DB, each submission. I couldn't post images or more than two URLs so I will try to explain it the best I can without screenshots.
So what happens is this information gets in the DB. Then there is the query'ing. I have a search page which uses an HTML form to select the type of information to be searched for. It then displays a synopsis of each report that matches the query. The user than enters the REPORT ID # for the report they want to view in full into another small form (an input field with a submit button) which brings them to a page with the full report displayed when they click submit.
So right now I am trying to do totals and realizing my DB will be needing some work and tweaking to make it easier to create querys for it for different information needed. I've gleaned some good information so far and will continue to try and provide concise information about my setup as best I can.
Thanks.

Maybe you can go to my photobucket and check them out, should let me do one link, there is five screenshots, you can kind of see better what I have happening there.

The query you are looking for would be very long and complicated for your current db schema.
Every table like (some_id, column1, column2, column3, column4... ) where columns store the same type of data can be also represented by a table (some_id, column_number, column_value ) where instead of 1 row with values for 20 columns you have 20 rows.
So your table should rather look like:
officer ct_number ct_value
1 CT1 TSTO
1 CT2 DOME
1 CT3 TSTO
1 CT4 ASBA
(...)
2 CT1 DOME
2 CT2 TSTO
For a table like this if you wanted to find how many occurences of different ct_values are there for officer 1 you would use a simple query:
SELECT officer, ct_value, count(ct_value) AS ct_count
FROM reports WHERE officer=1 GROUP BY ct_value
giving results
officer ct_value ct_count
1 TSTO 2
1 DOME 1
1 ASBA 1
If you wanted to find out how many TSTO's are there for different officers you would use:
SELECT officer, ct_value, count( officer ) as ct_count FROM reports
WHERE ct_value='TSTO' GROUP BY officer
giving results
officer ct_value ct_count
1 TSTO 2
2 TSTO 1
Also any type of query for your old schema can be easily converted to new schema.
However if you need store additional information about every particular report I suggest having two tables:
Submissions
submission_id report_id ct_number ct_value
primary key
auto-increment
------------------------------------------------
1 1 CT1 TSTO
2 1 CT2 DOME
3 1 CT3 TSTO
4 1 CT4 ASBA
5 2 CT1 DOME
6 2 CT2 TSTO
with report_id pointing to a record in another table with as many columns as you need for additional data:
Reports
report_id officer date some_other_data
primary key
auto-increment
--------------------------------------------------------------------
1 1 2011-04-29 11:28:15 Everything went ok
2 2 2011-04-29 14:01:00 There were troubles
Example:
How many TSTO's are there for different officers:
SELECT r.officer, s.ct_value, count( officer ) as ct_count
FROM submissions s JOIN reports r ON s.report_id = r.report_id
WHERE s.ct_value='TSTO'
GROUP BY r.officer
