Based on the given marks for each student in different subjects. Student is marked as failed if marks in any subject is less than 30.
I want to see if student has passed or failed using Informatica PowerCenter.
Input:
Please see the image of Student table
My approach is to normalize the input data as below:
A 50,80,60
b 29,45,50
Then use substring to see if any value seperated by comma(,) is less than 30, then Mark his as Fail.
Please suggest.
DESIRED OUTPUT:
A PASS
B FAIL
Just use an aggregator grouped by studentid returning min(Marks). The next transformation would be an expression to set a boolean based on whether the min value passed from the aggregator is above 30 or not. Is this your homework?

I'm with a non-profit. We divide the state up into 16 regions for administrative purposes. I'm trying to find out how many members live in each region. We have 4 different types of members too. There's a table that lists all the members. There is also a table in which we have listed all the towns in the state and put in which of our regions the town is in. For the first member type the record has the value "1" in the TYPE field. I'm trying to write an expression that basically says this. If the TYPE field has a "1" in it, then the condition is true, return 1. Else return 0. Then sum up all the ones.
I didn't build the database or the query. This is the expression that was already there: INDIVIDUAL: Sum(IIf([Membership.TYPE]=1,1,0)) The sum that it comes up with just doesn't make sense.
Edit: I hope I did this right. Here is a table showing what information the query returns except for the 502 and the 96 which I put there as a check. The values in that one column add up to 502 but they should add up to 674. The 96 should be 113.

I have a table containing the following: Five Y/N fields and a calculated field [Priority Results] that totals the number of 'Yeses' from those five y/n fields. I'm trying to create another calculated field that will return a value of Low, Medium or High dependent on the number of boxes that have been checked. [Priority Results] currently returns the values 0 through -5. Low = 0 & -1, Medium = -2, High = -3 or lower. I've tried SEVERAL different versions of If/Then, If/Else, Iif statements and always receive a syntax error. I've read a lot of different sites and the following expression seems to be the most commonly used, but I'm still getting the error. Anyone have any ideas? I've even tried this statement on a non-calculated field and can't get it to work.
IIf([Priority results]<="-1","Low",IIf([Priority results]="-2","Medium",IIf([Priority results]>="-3","High")))
Here are the calculated field [Priority results] properties.
Expression:
[Class Non-Attendance]+[Instructor Referral]+[Late Registration]+[Low Starting GPA]+[Talon Log-in]
Result Type: Long Integer
enter image description here
The part of the table this question relates to has the following fields:
Class Non-Attendance: Yes/No
Instructor Referral: Yes/No
Late Registration: Yes/No
Low Starting GPA: Yes/No
Talon Log-In: Yes/No
Priority Results: Calculated field counting the Yes/No fields above
Priority Outcome: Calculated field (that isn't working) prioritizing based on Priority Results
Don't put parameters for number fields in quotes.
Consider:
IIf(Abs([Priority Results])<=1, "Low", IIf(Abs([Priority Results])=2, "Medium", "High"))
In a query or textbox, expression could be:
Switch(Abs([Priority Results])<=1, "Low", Abs([Priority Results])=2, "Medium", True, "High")
Parts of the question still confuse me, which is why this answer will be brief. You have a calculated field PriorityOutcome based on another calculated field PriorityResults and that is the problem. Access doesn't calculate PriorityResults before calculating PriorityOutcome. Instead Access says PriorityResults doesn't exist yet and passes null to PriorityOutcome resulting in either an error or a silent fail.
There are several fixes you can mix and match. You can repeat the calculation for PriorityResults inside PriorityOutcome: wasteful but often the fastest solution. You can also add a code module with public functions to do part or all of the calculations. Then refer to those public functions in your calculated fields Access intellisense can find public functions.
I am trying to make a query for approval of documents, where the result display the name and signature with date. How can I get the date for two people approving the document?
Select Uname
case when stepcode=1 then 'approver1' end as 'name of person'
case when stepcode=1 then 'approver1' end as ' date of signed noted'
case when stepcode=2 then 'approver2' end as 'date of signed approved'
from table
I tried this, but only one result showed up. Only the name, signature and date of the first approval displayed.
We can only answer this by making some assumptions:
the field stepcode denotes what stage of the sign off process the record is at
value of 1 means noted and value 2 means approved. A value of 0 means nothing has happened yet
approver1 and approver 2 are NULL if the action has not yet taken place
If all of the above is true, then there should be no requirement to have a CASE statement for the fields... just including the fields within the SELECT statement will bring the values through if they have been completed.
Some validation of data might be required here though if you are not getting the results you are expecting. Running some rough counts for each of the steps and for where they have values in the approver fields would help to make sure your code is working. The following should give you something to work with:
SELECT
stepcode
COUNT(TableID) AS NumberAtStep
FROM table
GROUP BY stepcode
Using these counts, you can then run your statement without the CASE statements and run a manual count to ensure you are seeing the right number of records with the relevant populated columns for each step.
Further information will be required to delve into your problem further however
I have a table with three columns, in column 1 I have a name and column 2 I have a quantity.
I want to look up column 1 and return the value in column 2.
I used to the expression below and it wouldn't return what I wanted.
=Lookup(fields!NAME.Value, "Paul" ,1 , 0)
Could anybody tell me what expression I need to use?
You are close, sort of. To use the Lookup function properly, you need to change some things. Here is an example using the Lookup function.
=Lookup(Fields!Field1.Value, Fields!Field1.Value, Fields!Field2.Value, "DatasetB")
It takes 4 parameters. The first is the field/value from the current (in scope) data set that you want to be the value to match in the lookup data set. The second is the field in the lookup data set to match on. The third in the field to return when a match is found, and the last parameter is the name of the lookup data set.
Based on the expression in your question, it may actually work like this:
=Lookup("Paul" , Fields!NAME.Value, Fields!QUANTITY.Value , "DataSet2")
Of course, hard coding the name in the first parameter is probably not what you want to do.
My dataset currently has 12 rows of data. Each representing data for a month. I would like to have variance of a column between to rows, the rows being last & last but one i.e., latest month and previous month's data.
It could have been simple if I were to work on tablix but thats not the case. I want those values for a textbox.
Any ideas on it anyone?
I hope you are using SSRS 2008R2:
R2 introduced the Lookup function that is perfect for this scenario.
=Lookup( Fields!ProductUID.Value ,Fields!ProductID.Value,Fields!Price.Value,"PriceDataSet")
The Lookup function above will evaluate the first parameter ("Fields!ProductUID.Value") in the current dataset, then look for a matching value in the field specified in the second parameter ("Fields!ProductID.Value") in the dataset specified in the fourth parameter. The value of the third parameter is then evaluated in that row of the dataset and returned.
A little convoluted, but very helpful.
In your case, you can use this in a textbox with a calculated a static number:
=Lookup(
Month(DateAdd(DateInterval.Month, -1, GetDate())),
Fields!MonthID.Value,
Fields!Name.Value,
"DataSet1")
This should calculate a number for last month, then look for a match in DataSet1.
In this example I have a tablix with Statecode and name as below
enter image description here
Suppose you want to display the name of state of CA, write an expression as -
=Lookup(
"CA" ,
Fields!StateCode.Value,
Fields!StateName.Value,
"ReportData"
)
This will return 'California' in the text box
I ran across this post while trying to solve a similar problem but with columns of double data type. Not sure why but SSRS did not want to return my first row using LOOKUP in combination with ROW_NUMBER in SQL(If someone can solve that all the better). I ended up using a SUM(IIF) instead. Hopefully, this is useful for someone else.
=Sum(IIF(Fields!RowNum.Value=1,CDBL(Fields!MyNumericColumn.Value),CDBL(0)))
Note: If SSRS complains about data types, just cast both parts of the IIF to the desired data type.
