Hi,
I need to create a conditional expresssion where if a null value is found, then a letter "N" must be inserted.
I create this expression but didnt work: (COL1 == NULL) ? "N" : COL1
So, if COL1 is null, then N .. but if it is nt null tehn COL1 = COL1
I think i', having a problem expressing the null.
Any idea for this?
Thanks!
I'm using a conditional split to discriminate modified records. My expression looks like this: col1_source != col1_dest || col2_source != col2_des.....and so on. I use OLE DB Command afterward to update modified records.
It all works fine if no columns evaluate to null. If any (source or dest.) evaluates to null, component fails.
Any tips how to solve a problem?
It has to work like this:
If colX_source is null and colX_dest is not null --> Update If colX_source is not null and colX_dest is null --> Update If both colX_source and colX_dest are null --> No update
p.s. i apologize if a similar thread exists, I haven't found something of use to me.
I have a query with a conditional expression that I can do just fine in Access but I am having a bear of a time trying to create a similar SQL View. Baiscally I want to say, if column A is null, use value B else use value C.
In Access the SQL is this:
SELECT IIf([Categorycode] Is Null,[tblconstituents].[CASNumber],[categorycode]) AS Casnumber, Sum(qryweldingrod3a.CFume) AS CFume, Sum(qryweldingrod3a.cslag) AS cSlag FROM qryweldingrod3a INNER JOIN tblconstituents ON qryweldingrod3a.CASNumber = tblconstituents.CASNumber GROUP BY IIf([Categorycode] Is Null,[tblconstituents].[CASNumber],[categorycode]);
But I know you can't use the IIF statement in SQL so I was trying CASE and was still coming up empty handed. Here is what I produced in SQL but it didn't work:
SELECT SUM(dbo.RecycleWR_qryWeldingRod3a_LBS.CFume) AS CFume, SUM(dbo.RecycleWR_qryWeldingRod3a_LBS.CSlag) AS cSlag,
CASNumber = CASE Type WHEN categoryCode IS NULL THEN dbo.tblConstituents.CASNumber ELSE CategoryCode END, FROM dbo.tblConstituents INNER JOIN dbo.RecycleWR_qryWeldingRod3a_LBS ON dbo.tblConstituents.CASNumber = dbo.RecycleWR_qryWeldingRod3a_LBS.CASNumber GROUP BY dbo.RecycleWR_qryWeldingRod3a_LBS.CASNumber
I have as csv-file wich I import into an SQL Server table. Now I want to do some checks on it. I use a conditional split to direct data to the other tables (1 table for the correct data, 1 table for the rejected data).
Is it possible to use a regular expression in a case in a conditional split to check if a columns has the right format?
I want to do conditional processing depending on values in the rows of a CTE. For example, is the following kind of thing possible with a CTE?:
WITH Orders_CTE (TerritoryId, ContactId) AS ( SELECT TerritoryId, ContactId FROM Sales.SalesOrderHeader WHERE (ContactId < 200) ) IF Orders_CTE.TerritoryId > 3 BEGIN /* Do some processing here */ END ELSE BEGIN /* Do something else here */ END
When I try this, I get a syntax error near the keyword 'IF'
Any ideas? I know this kind of thing can be done with a cursor but wanted to keep with the times and avoid using one!
I think I know the answer to this but thought I'd ask anyway.
I have a conditional split to check a column for null values or empty string values. It looks like this:
(!ISNULL(Ballot)) || (LEN(TRIM(Ballot)) > 0) My question is: Are both sides of the expression evaluated? My testing says yes, because a Null value causes an error. Is there a way to short circuit the evaluation like the || operator in C# or the (less than elegant, and seemingly threatening) OrElse operator in VB? Whats the best alternative:
A slightly more complex expression that turns a null value into an empty string
A script component
Two conditional splits
Two paths out of one condtional split
I went with the first option, here is the expression I came up with:
I'm trying to put conditional formatting on a field, that behaves as follows:
The data in the field is varchar, and sample data is either:
NULL 3.0 :0 11.7 :1 (these are ratios of a sort)
I want to evaluate the first 3 characters of the string as numbers.
Example: Mid(fieldvalue,1,3) = "3.0" or "11."
Any data that is greater than 1.99, I want to make the background dark red, anything else including nulls, zebra formatting. I have the following expression built so far and it appears to work, except when the value is null. If the value is null, it leaves the background color white.
This is the warning: [rsRuntimeErrorInExpression] The BackgroundColor expression for the text box "Asthma" contains an error: Input string was not in a correct format.
=iif( isnothing(Fields!Asthma.Value) ,(IIf(RowNumber(Nothing) Mod 2 = 0,"#b8cce4","#dbe5f1")) ,(iif(mid(Fields!Asthma.Value,1,3)>1.99 ,"DarkRed" ,IIf(RowNumber(Nothing) Mod 2 = 0,"#b8cce4","#dbe5f1"))))
My logic is, if the field is null, zebra format, if mid of the value is > 1.99, dark red, everything else zebra formatting. As I said, this seems to work except for nulls.
A little puzzle with this Error - Status and PropertyType fields do not allow nulls while other columns do ( there are about 20 columns in original expression but left out for simplicity - these are created the same way ). Any ideas how to solve it?
[Conditional Split Filter Changes [813]] Error: The expression
on "output "Listing Changed" (885)" evaluated to NULL, but the "component "Conditional Split Filter Changes" (813)" requires a Boolean results. (My wish for next version is to have better expression editor and be able to see the output for those in dataflow transforms with lets say sample 200 rows)
There was a similar question to mine a few time ago about conditional execution, but I'm having some problems with it to which I couldn't find any answer, could anyone help?
My condition is checking if a DateTime from a DB table is null. I use the Execute SQL Task to retrieve the record (SELECT TOP 1 * FROM myTable WHERE conditions = TRUE), then I map 2 fields to their respective global variables.
Then I created the green arrow connector and used a precedence expression based on sucess. I used the expression IsNull(@variable). For some reason, even if the @variable comes as null - I checked the info in the DB - it still comes out as '1999-11-30'
I've looked around and the IsNull method can be used to also change the value in the event of it being null, could it be changing my variables value to this even if I didn't pass that value as a parameter to the function? If so, how else can I test it for null? I've tried "== null", "= null" and even ".equals(null)" - which I know is absurd, but I'm running out of options here...
Could you enlighten me, please??? Thanks in advance!
I would like an example of checking for NULL within an expression. I don't know the correct syntax. Checking for IsNull is incorrect so is IS Null. Can anyone help me?
I would like to know how I can indicate a NULL value in a report expression in SSRS / Report Designer.
I am trying to code :
IIF(Value_A = 0, <NULL>, Value_A)
It may look weird but I am trying to return NULL values when Value_A is 0 (zero), in the sample scenario above.
I have tried using the keyword "NULL", but it is highlighted as a syntax error, and suggested to use System.DBNull. I tried it and then it says that components of the System collection cannot be used in an expression, so I am left drawing blanks.
I have a column say 'ActivationDate' which is a (database timestamp [DT_DBTIMESTAMP]) which I want to replace with an expression in derived columns
The condition is if 'ActivationDate' field is null or '' then 'Null' else 'ActivationDate'
I am struggling to write this condition. Without condition i.e. at present it saves the value in this database '1753-01-01 00:00:00.000'. In the preview the 'ActivationDate'field does not show any thing so I recon it is either null or ''
Is there a way in order to execute a subscribed report based on a certain criteria?
For example, let's say send a report to users when data exist on the report else if no data is returned by the query executed by the report then it will not send the report to users.
My current situation here is that users tend to say that this should not happen, since no pertinent information is contained in the report, why would they receive email with blank data in it.
Hey. I need to substitute a value from a table if the input var is null. This is fine if the value coming from table is not null. But, it the table value is also null, it doesn't work. The problem I'm getting is in the isnull line which is in Dark green color because @inFileVersion is set to null explicitly and when the isnull function evaluates, value returned from DR.FileVersion is also null which is correct. I want the null=null to return true which is why i set ansi_nulls off. But it doesn't return anything. And the select statement should return something but in my case it returns null. If I comment the isnull statements in the where clause, everything works fine. Please tell me what am I doing wrong. Is it possible to do this without setting the ansi_nulls to off??? Thank you
set ansi_nulls off
go
declare
@inFileName VARCHAR (100),
@inFileSize INT,
@Id int,
@inlanguageid INT,
@inFileVersion VARCHAR (100),
@ExeState int
set @inFileName = 'A0006337.EXE'
set @inFileSize = 28796
set @Id= 1
set @inlanguageid =null
set @inFileVersion =NULL
set @ExeState =0
select Dr.StateID from table1 dR
where
DR.[FileName] = @inFileName
AND DR.FileSize =@inFileSize
AND DR.FileVersion = isnull(@inFileVersion,DR.FileVersion)

I have created 1 report with 2 datasets. This report is attached to the 1st dataset.For example,1st one is "Smallappliances", 2nd is "Largeappliances".
I created a tablix and, the 1st column extracts Total sales per Sales person between 2 dates from 1st dataset (Small appliances). I used running values expression and it works fine.
Now, I would like to add another column that extracts Total sales per sales person between 2 dates from 2nd dataset (Large appliances). I am aware that I need to use Lookup expression and it is giving me the single sales value rather than the total sales values. So, I wanted to use RunningValue expression within lookup table to get total sales for large appliances.
This is the lookup expression that I added for the 2nd column.
I get this error when I preview the report.An error occurred during local report processing.The definition of the report is invalid.An unexpected error occurred in report processing.
I have the following code in the color property of a textbox. However, when I run my report all of the values in this column display in green regardless of their value.
In my report i have CNAME parameter , which allows null value. I checked Allow null value check box in report parameter properties.
when i preview the report , it displays checked NULL check box beside CNAME parameter . I want to give some meaningful name(i.e.ALLCustomers) to this checkbox instead of NULL.
In the flat file SampleID and Product are populated in the first row only, rest of the rows only have values for Rep_Number, Protein, Fat, Solids.
SampleID and Product are blank for the rest of the rows. So my task is to fill those blank rows with the first row that has the sampleID and Product and load into the table.
I have a report that is run on a monthly basis with a default date of null. The stored procedure determines the month-end date that it should use should it be sent a null date.
The report works fine when I tell it to create a history entry; however, when I try to add a subscription it doesn't appear to like the null parameter value. Since I have told the report to have a default value of null it doesn't allow me to enter a value on the subscription page.
Now, I suppose I could remove the parameter altogether from the stored proc, but then the users would never be able to run the report for a previous time period. Can someone explain to me why default values aren't allowed to be used on subscriptions when they seem to work fine for ad hoc and scheduled reports? This is really quite frustrating as most of my reports require a date value and default to null so that the user doesn't have to enter them for the latest data.
An internal error occurred on the report server. See the error log for more details. (rsInternalError) Get Online Help
I run a stored procedure for which I have a return variable. The stored procedure returns the ID of a row in a table if it exists:
m_sqlCmd.ExecuteScalar();
The m_sqlCmd has been fed an SQLParameter with direction set to output. When the stored proc returns, I want to test it. Now when there IS a row it returns the ID ok. When the row doesn't exist, in my watch I have:
m_sqlParam.SqlValue with value {Null}
I can't seem to work out how to test this value out. I've tried several things but none seem to work.
This line compiles ok, but the following runs into the IF statement as if the SqlValue is null??
if (m_sqlParam.SqlValue != null).... {
// I'm here!! I thought the watch says this is null??? }
Sorry if this is obvious, but I can't work this one out!!
Looks like there was a fix and then I read this fix is not a fix. Does anyone know how this can be rectified? Does it mean that only Windows authentiation is the only way it works. The Software is over 2 years old, there are no excuses.
I am getting this error: "Cannot insert the value NULL into column 'OrderID', table 'outman.outman.Contact'; column does not allow nulls. INSERT fails." -- But my value is not null. I did a response.write on it and it show the value. Of course, it would be nice if I could do a breakpoint but that doesn't seem to be working. I'll attach a couple of images below of my code, the error, and the breakpoint error.
