I have a requirement to hide a column, if no value exits in that column. But i have a grouping(Parent : Employee Number, Child: Category) in the report. In some of the group result may have value, but some of then does not have.
Example screen shot attached.
If you check the above image, second employee(Shiju) does not have Category. So for the second employee(Shiju) - need to hide Category column.
I tried with "Column Visibility" option and Column Groups > select Column > write expression in "Hidden" property. Following is the expr.
=iif(CountDistinct(Fields!Cat.Value) = 0,True,False)
These two options did not work.
Please give any solution for this.
Thanks in advance.
Your expression is almost correct, you just need to format the 0 else it will treat it as nothing:
=IIF(CountDistinct(Fields!cat.Value)=cint(0),true,false)
The other thing to check is that the field is actually null or nothing rather than blank strings or spaces.

I want to add a column called "Sweep" that contains bools based on whether the "Result" was a sweep or not. So I want the value in the "Sweep" column to be True if the "Result" is '4-0' or '0-4' and False if it isn't.
This is a part of the table:
I tried this:
ALTER TABLE "NBA_finals_1950-2018"
ADD "Sweep" BOOL;
UPDATE "NBA_finals_1950-2018"
SET "Sweep" = ("Result" = '4-0' OR "Result" = '0-4');
But for some reason, when I run this code...:
SELECT *
FROM "NBA_finals_1950-2018"
ORDER BY "Year";
...only one of the rows (last row) has the value True even though there are other rows where the result is a sweep ('4-0' or '0-4') as shown in the picture below.
I don't know why this is happening but I guess there is something wrong with the UPDATE...SET code. Please help.
Thanks in advance.
NOTE: I am using PostgreSQL 13
This would occur if the strings are not really what they look like -- this is often due to spaces at the beginning or end. Or perhaps to hyphens being different, or other look-alike characters.
You just need to find the right pattern. So so with a select. This returns no values:
select *
from "NBA_finals_1950-2018"
where "Result" in ('4-0', '0-4');
You can try:
where "Result" like '%0-4%' or
"Result" like '%4-0%'
But, this should do what you want:
where "Result" like '%4%' and
"Result" like '%0%'
because the numbers are all single digits.
You can incorporate this into the update statement.
Note: double quotes are a bad idea. I would recommend creating tables and columns without escaping the names.
I've created a database with about 15000 records and I want to create a form that filters the records according to entries inputed in textboxes through a Query. For the most of my columns i've used this Expression :
Like "*" & [Forms]![Testform]![Testtxt] & "*"
I use "Like" so that if the user decides not to input anything in a textbox, the query ignores that parameter. However when it comes to Dates (I have two columns that contain Dates) I can't make it ignore the empty textbox when the user decides not to write anything. Can you help me make the expression below show all the records in the query if the DateTesttxt is empty ?
> [Forms]![TestForm]![DateTesttxt]
If you're using query designer, just add another condition
Is Null
so visually in query builder it will be something like:
Criteria: > [Forms]![TestForm]![DateTesttxt]
or: Is Null
UPDATE:
This should work as well as a single expression:
Is Null Or > [Forms]![TestForm]![DateTesttxt]
and it is more correct solution in case if you have conditions on more than one column
I just created 2 cross table using wizard function of Telerik Standalone report designer tool
since ISCED 5 has values for private and public its showing properly
using same query I created second cross tab and
but since ISCED 6 table doesnt have values for "public" section its showing like this
how to show as zero for public section 2nd cross tab (when no values for specific row)
You should modify the value of the field using an expression to evaluate your condition.
Select the textbox containing the data corresponding to the column you like to format when the value is null.
In the property pan on the right select "Value"
Write in there your expression, it should be something like this:
=Iif(Fields.MyField IS Null,"0",Fields.MyField)
You should also consider if the value instead of null is empty and eventually cover this case in the expression if applicable.
= Iif(Fields.MyField IS Null OR Fields.MyField = "", "0", Fields.MyField)
More information on conditional formatting can be found here.
Let us know if this works for you.
I have a report in 2005 SSRS which I want to add a parameter to. The parameter would be comprised of a group of zip codes, but be selected as a single item in the list.
For example, I would like to have 5 zip codes as one selection in the list and 3 for another, etc:
Select 11111,22222,33333,44444,55555,66666 AS Boondock
Select 77777,88888,99999 AS Timbuck
Select Zip Codes NOT IN (11111-99999) AS Everything Else
So my selections in the dropdown would be:
Boondock
Timbuck
Everything Else
Can anyone help me with how I should go about creating this parameter?
Create a simple string parameter to present to the user. Let's call it ZipCodeSet.
Create a dataset that examines the #ZipCodeSet parameter and returns the appropriate list of zip codes. Call it ZipCodeSelection.
Create an internal multivaue parameter that uses ZipCodeSelection as both its Available Values and Default Values. Call it SelectedZipCodes.
Use SelectedZipCodes in your report's datasets.
The easiest solution here would probably to use a Calculated Field on your dataset, called LocationDescription, for example:
=SWITCH(Fields!ZipCode >= 11111 and Fields!ZipCode <= 66666, "Boondock", Fields!ZipCode >= 77777 and Fields!ZipCode <= 99999, "Timbuck",True, "Everywhere Else")
The lone true statement at the end is due to the SWITCH expression reading left-to-right and exiting once it evaluates one of the switches as TRUE. This way for each of the items in your table of ZipCodes you will always end up with a TRUE result.
I assume you're evaluating a range of ZipCodes, and not exact values of 11111,22222, and so on? If so, the switch will have more values. A sample of your data would help if you want an exact answer.
Once you have built your Calculated Field, you can then set up a Parameter (called #LocationParameter) with available values based on a query of your LocationDescription field, then just filter your dataset using:
Expression:
= Fields!LocationDescription
Operator: =
Value:
#LocationParameter
(if you want multiple selections on your parameter, change the operator to IN)
Hope that helps.
Well basically I would like to be able to use a parameter on iReport with an aggregate function.
If you type "yes" it will show you the values greater than 0, if you type "no" it will show the values that are less than 0. However, the aggregate function first adds up all the values related to an id and then it subtracts the result from another value, the result of that is the one I want to show.
How would I be able to do this? I'm clueless as I don't know how to use it with HAVING.
I don't understand what 'it' refers to in "I don't know how to use it with HAVING." The question will be much clearer with some SQL. But I guess you're looking for this:
SELECT id, sum(values) as the_agg
FROM table1
GROUP BY id
HAVING sum(values) $P!{BiggerOrSmaller} 0
The default value for the parameter BiggerOrSmaller should be like this:
$P{MyParam}.equals("yes") ? ">" : "<"
This assumes you have a parmeter called MyParam which can take the value "yes". Based on that value it sets the parameter BiggerOrSmaller appropriately.
