I'm very new in using Cognos report studio and trying to filter some of the values and replace them into others.
I currently have values that are coming out as blanks and want to replace them as string "Property Claims"
what i'm trying to use in my main query is
CASE WHEN [Portfolio] is null
then 'Property Claims'
ELSE [Portfolio]
which is giving me an error. Also have a different filter i want to put in to replace windscreen flags to a string value rather than a number. For example if the flag is 1 i want to place it as 'Windscreen Claims'.
if [Claim Windscreen Flag] = 1
then ('Windscreen')
Else [Claim Windscreen Flag]
None of this works with the same error....can someone give me a hand?
Your first CASE statement is missing the END. The error message should be pretty clear. But there is a simpler way to do that:
coalesce([Portfolio], 'Property Claims')
The second problem is similar: Your IF...THEN...ELSE statement is missing a bunch of parentheses. But after correcting that you may have problems with incompatible data types. You may need to cast the numbers to strings:
case
when [Claim Windscreen Flag] = 1 then ('Windscreen')
else cast([Claim Windscreen Flag], varchar(50))
end
In future, please include the error messages.
it might be syntax
IS NULL (instead of = null)
NULL is not blank. You might also want = ' '
case might need an else and END at the bottom
referring to a data type as something else can cause errors. For example a numeric like [Sales] = 'Jane Doe'
For example (assuming the result is a string and data item 2 is also a string),
case
when([data item 1] IS NULL)Then('X')
when([data item 1] = ' ')Then('X')
else([data item 2])
end
Also, if you want to show a data item as a different type, you can use CAST

I'm getting this message in Redshift: invalid input syntax for type numeric: " " , even after trying to implement the advice found in SO.
I am trying to convert text to number.
In my inner join, I try to make sure that the text being processed is first converted to null when there is an empty string, like so:
nullif(trim(atl.original_pricev::text),'') as original_price
... I noticed from a related post on coalesce that you have to convert the value to text before you can try and nullif it.
Then in the outer join, I test to see that there's a limited set of acceptable characters and if this test is met I try to do the to_number conversion:
,case
when regexp_instr(trim(atl.original_price),'[^0-9.$,]')=0
then to_number(atl.original_price,'FM999999999D00')
else null
end as original_price2
At this point I get the above error and unfortunately I can't see the details in datagrip to get the offending value.
So my questions are:
I notice that there is an empty space in my error message:
invalid input syntax for type numeric: " " . Does this error have the exact same meaning as
invalid input syntax for type numeric:'' which is what I see in similar posts??
Of course: what am I doing wrong?
Thanks!
It's hard to know for sure without some data and the complete code to try and reproduce the example, but as some have mentioned in the comments the most likely cause is the to_number() function you are using.
In the earlier code fragment you are converting original_price to text (string) and then substituting an empty string ('') if the value is NULL. Calling the to_number() function on an empty string will give you the error described.
Without the full SQL statement it's not clear why you're putting the nullif() function around the original_price in the "inner join" or how whether the CASE statement is really in an outer join clause or one of the columns returned by the query. However you could perhaps alter the nullif() to substitute a value that can be converted to a number e.g. '0.00' instead of ''.
Sorry I couldn't share real data. I spent the weekend testing small sets to try and trap the error. I found that the error was caused by the input string having no numbers, which is permitted by my regex filter:
when regexp_instr(trim(atl.original_price),'[^0-9.$,]') .
I wrongly expected that a non numeric string like "$" would evaluate to NULL and then the to_number function would = NULL . But from experimenting it seems that it needs at least one number somewhere in the string. Otherwise it reduces the string argument to an empty string prior to running the to_number formatting and chokes.
For example select to_number(trim('$1'::text),'FM999999999999D00') will evaluate to 1 but select to_number(trim('$A'::text),'FM999999999999D00') will throw the empty string error.
My fix was to add an additional regex to my initial filter:
and regexp_instr(atl.original_price2,'[0-9]')>0 .
This ensures that at least one number will be in the string and after that the empty string error went away.
Hope my learning experience helps someone else.
I'm writing a macro to cycle through a number of different spreadsheets that are in exactly the same format as each other. The source spreadsheets contain data in a table which occasionally contains the #NUM error (thanks to something going wrong in a different model!)
I have managed to account for all other error types, and some interesting formatting rules, using the below with a few other Case statements:
If IsNumeric(resultsarray(q,p) = false then
Select case ResultsArray(q,p)
Case IsError(ResultsArray(q, p))
ResultsArray(q, p) = 0
Case Left(ResultsArray(q, p), 2) = "0 "
ResultsArray(q, p) = 0
Unfortunately #NUM doesn't seem to fall into IsError's purview. Does anyone out there know how I can simply overwrite the error with a zero/0?
Thanks in advance!!
Steph
This #NUM error occurs if the input is not a valid number. On your situation i suggets you to check whether the input is number or not instead of error check. This way you can check #NUM error as well.(Or you can do it both) With IsNumeric(<input data here>) you can do it. So just add one more case (IsNumeric) to your select case.
I'm getting a error I can't quite explain I have a Excel list I want to load into memory, to see if the next row is still a relative row I check if the cell has a value by doing If value = "" Then but the value is 1012738 and it gives me a unhandled exception...
I can't quite understand why the code is giving a error, the cell value is formatted just like all previous cells that were checked. But here a error is thrown.
Maybe i'm just not seeing it, and someone can explain?
You should check the value each time.
Dim o As Object = oSheet.Range(xxx).Value
If (o IsNot Nothing) Then
Select Case o.GetType
Case GetType(Double)
' do work here
Case GetType(Integer)
' do work here
...
End Select
Else
...
End If
Your image isn't showing up for me.
Most exceptions in excel are datatype related. Most likely, you either have a NULL or a string that looks like an integer to the human eye. You can blindly try using trim(), int() or str() etc as needed to make sure you're actually testing an integer or matching a string if thats what you are about or you can test them in a programmatic method.
First, the programmatic method of testing ... isEmpty or isNull are needed to ensure the cell is good ...
if isEmpty(value) Then
<do something>
This will most likely catch the error which is causing the message. If empty is failing, try testing with isNull. One means the cell is empty, the other means that it wasn't initialize (rarely an issue in excel, but if using vba code it can happen).
Also ... your if statement is setup in a less than optimal... used <> in place of if then + else ...
Your code ...
If value = "" Then
General formula when you want to test that something is not something else, use the not equals ...
if value <> "value" Then
"some operation"
I have a query calculation that should throw me either a value (if conditions are met) or a blank/null value.
The code is in the following form:
if([attribute] > 3)
then ('value')
else ('')
At the moment the only way I could find to obtain the result is the use of '' (i.e. an empty character string), but this a value as well, so when I subsequently count the number of distinct values in another query I struggle to get the correct number (the empty string should be removed from the count, if found).
I can get the result with the following code:
if (attribute='') in ([first_query].[attribute]))
then (count(distinct(attribute)-1)
else (count(distinct(attribute))
How to avoid the double calculation in all later queries involving the count of attribute?
I use this Cognos function:
nullif(1, 1)
I found out that this can be managed using the case when function:
case
when ([attribute] > 3)
then ('value')
end
The difference is that case when doesn't need to have all the possible options for Handling data, and if it founds a case that is not in the list it just returns a blank cell.
Perfect for what I needed (and not as well documented on the web as the opposite case, i.e. dealing with null cases that should be zero).
Good Day Everyone,
There is this something i've been trying to exercise in abap and that is the Displaying of column datas in ALV by retrieving the values from excel file into an internal table. I've been trying to debug my program for quite some time now and i can't seem to solve the error it's been stating which is "Field symbol has not yet been assigned" please guide me. I already made some research on how to solve this short dump error but most of the other issues posted on the net is selected from some specific table with column fields. I was just wondering that maybe my case is a little bit different from others.
The function that retrieved the values from excel is properly working and i have no problem at all in displaying them.Below is the code i constructed.

Any tips, tricks and advice in my program would be highly sought. Thanks in Advance
You're using a type which is not defined in the data dictionary. This requires a different approach when creating the ALV fieldcat. Try this:
l_wa_fcat-fieldname = 'COL1'.
l_wa_fcat-inttype = 'C'.
l_wa_fcat-outputlen = '30'.
l_wa_fcat-text_fieldname = 'Column 1'.
l_wa_fcat-seltext_s = 'Column 1'.
Also make sure you enter the fieldname value with capitalized letters.
I'm no ABAP expert but I noticed 2 things in the code you posted:
you said the error is "Field symbol has not yet been assigned" but you have no field symbol in your code. Maybe it's used inside one of the function modules you call. If so, try to post the code where the error pops up;
you use gt_tab[] which, if I remember well, is the way to access the body of an internal table with header line. In your code gt_tab is not an internal table with header line, but you use it to store one with function 'TEXT_CONVERT_XLS_TO_SAP' ;
Try to post the code where the error is being generated.

Sergiu
