My question it's quite simple.
Suppose I have a "StoredProcedure" that gives me a result of a table with 2 columns, say: "Name" and "Surname".
I want to show the table only if the result set is not empty.
If I drag&drop the "Name" and "Surname" fields to the "Details" section, it automatically generates in the Header section the name of those columns, but if the result set is empty, I still see the column names. What I want is to make the column names dissapear if there isn't any data to show.
Any idea of how to do this?, it sounds very reasonable so I guess the solution is simple, but I don't know it
I now realized this question is answered in other question I made.
Conditional printing depending of empty or null value in Crystal Reports
I guess that setting a conditional value on the column labels with the "Count()" function (I guess should be one), would make the job done.
If Count(someFieldOfTheResult) == 0 THEN
notShowLabel
ELSE
showLabel

Good afternoon,
I am very new to Crystal Reports, so am not sure where to look for this information and would appreciate if someone can point me in the right direction or tell me if what I am asking for is impossible.
One of our departments uses a field called RecordChanges to note changes made to a record. The field is text and the department stores information there about the date a change is made and the type of change, separated by commas (i know this is terribly inefficient, but it's what I have to work with). I have a Crystal Report that parses this text field and picks up the latest date and latest change made to the record. I would like to modify this report to include ALL the changes made to the record, so if the field RecordChanges of the data source has 3 dates, I would like this record to appear in my Crystal Report 3 times, once for each change that was made. How to parse the field I can figure out but where I'm stuck is how do I make the number of times a record appears equal to the number of dates found which is my {#DateFound} field?
There is a lack of details, but as far as I understood the problem and assuming that you did state in the comment that "there wouldn't ever be more than 5 changes to an order", here is a first try to tackle the situation.
I will assume that you already have a formula that "parses this text field and picks up the latest date and latest change made to the record". And that you know how to adjust this formula to pick up each of the record changes. I will name this formula as {#Parser1}.
Based on {#Parser1}, create other 4 formulas: {#Parser2}, {#Parser3}, {#Parser4}, {#Parser5}. As you probably presume, each formula must be changed to parser the Nth occurrence of the record change.
Create 5 details sections.
Put each formula in each detail section.
Suppress the detail section wich formula is null or empty.
That's it.
The limitation is that you can have at most 5 record changes.
This is an awkward solution, but it is necessary (as far as I know) since Crystal Reports works based on your data rows. It iterates over the rows, but cannot "generate" more rows by itself. If you can manipulate the data source, you can create other solutions.
You still need to do the magic trick to pickup the Nth change from the text.
Image showing problem
I want to know if there is a way of repeating the result of a column downwards until the change of result.
Attached image shows the problem.
I need 9.1stWC column to fill the number(which is actually a string) all the way down until that number changes.
The column is not null where the blank fields are (9.is null, shows this) so I'm going to have to write additional formulas to show I'm guessing.
I've used previous function but that only shows for the next line down then is blank after.
The replicate string function will go across the column not downwards.
I've looked at a stringVar but cant find a way of making this work on this report.
I'm reserved about grouping as I have a lot of other filters and by grouping I could possibly loose the sequence depending on what I group by.
My aim is to show WC which are equal to the current op line by doing a simple formula after I have managed to populate that column
I will assume your column is a field named {Result.WC}.
Try this:
Create a formula. Let's call it #LastWC.
Use this code in the formula:
shared stringvar sharedLastWC;
if not isnull({Result.WC}) and {Result.WC} <> "" then sharedLastWC := {Result.WC};
sharedLastWC; //returns
Replace the field by the formula.
The idea behind this is to set the shared variable when the field is not blank and not null. So, the variable will hold the last "filled" value.
I can't make a test with the purposed solution right now, but give it a try and make adjusts if you need. Tell me if it does not work.
If the first row can be empty, you may need to create an aditional formula do start the value of the shared variable in the header of the report.
I am developing an SSRS 2008 report. I created a tablix, however, when I view this report one of the rows has zero entries. This row is not showing in the output. How can I make it show regardless of values so that it will just show "0" otherwise?
This was the expression I used for it:
=iif(CountDistinct(Fields!Client.Value)=0 or
isnothing(countdistinct(Fields!Client.Value)),0,
CountDistinct(Fields!Client.Value))
And I have tried grouping on different fields and also filtering on another field, but none of these make it appear when there is no data.
I think that the best you can do is ensuring that the dataset you are using has the record you want, even if it is null. For example, if you are grouping months, and you want all 12 months to appear in your tablix, then you need to make those months to exist in your dataset even if they have null values for all the other columns.
I'm stuck on a problem with a formula field in Crystal Reports and I keep going around in circles. I'll try my best to explain it.
The report I'm creating will be exported as a data file. It uses 3 tables, with work_table as the main table. work_table is joined to a view called order_item_with_aux using two fields, orderhdr_id and order_item_seq; it's an inner join. I don't think this has much bearing on my problem but, work_table is also joined to the customer_address table on customer_id and customer_address_seq.
In my output, I've included several fields from all three tables. Where I'm stuck is creating a formula field to populate a #Split field. Here's what I'm writing in my formula:
if {order_item_with_aux.zzaux_no_renewal_notices} = "Y" then "B"
else {work_table.split_value}
This results in the #Split field being populated with "B" for records on the work_table whose corresponding record on the order_item_with_aux view has zzaux_no_renewal_notices equal to "Y". The value of #Split for all other records displayed is blank. I've tried several variations of the above formula all to no avail. I've also tried setting a variable and handling it that way, but again, no go.
Anyone have any ideas? Please let me know if there's more info I can provide.
You need to test for null values first:
if isnull({order_item_with_aux.zzaux_no_renewal_notices}) then
"missing value"
else if {order_item_with_aux.zzaux_no_renewal_notices} = "Y" then
"B"
else
{work_table.split_value}
I have the following issue: I have a report that uses a Dataset as its datasource. The dataset has two tables, one would be the main table, say Employee, and the second table is EmployeePaycheck, so an employee can have several paychecks. I can compute the sum of a column in the second table, say paycheckValue, but what I can't seem to do is also add to this computed field the value of some additional fields in the Employee table, such as ChristmasBonus or YearlyBonus, to see how much the employee was paid at the end of the year.
Without knowing more information on this it will be difficult to answer, but I'll give you a couple things to look for.
First, I would make sure that the fields are of a similar type that will allow for a summary. For example, if one is a string then a summary wouldn't be able to be done without casting or convertingthe value to a number. I'm assuming that the fields are probably number or decimal columns so that is probably not the case.
I'd also check to make sure that none of the values that you are trying to sum are null. I haven't tested this, but I believe that it will not sum correctly if one of the rows has a null value. In this scenario you should just be able to use a formula field to check for the null and if the field is null return 0 instead. Then you can use the formula field in your calculations instead of the field itself.
If neither of these are the case please provide a little more info how you are computing the fields and what is happening when you do it.
Hope this helps.
