Conditional Execution With Null Checking For DateTime Field

Mar 11, 2008

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!

Problem With Isnull. Need To Substitute Null If A Var Is Null And Compare It To Null And Return True

Sep 20, 2006

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)

AND DR.languageid = isnull(@inlanguageid,null)

AND DR.[ID]= @ID

)

go

set ansi_nulls on

Integration Services :: SSIS Insert Non Null Value Into Null Rows

Jul 15, 2015

I have a flat file with the following columns

SampleID   Rep_Number   Product  Protein   Fat   Solids

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.

Subscription Issue With Null Default Parameter - Key Cannot Be Null

May 3, 2007

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




Key cannot be null. Parameter name: key

Returned SQLParam.SqlValue Is {Null} But Can't Test For Null?

Nov 5, 2007

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!!

WITH RETURNS NULL ON NULL INPUT Not Working?

May 3, 2006

Hello.

I've built a sample CLR function with the following declaration....

CREATE FUNCTION GetManager(@DeptCode nvarchar(3))
RETURNS nvarchar(1000)
WITH RETURNS NULL ON NULL INPUT
AS
EXTERNAL NAME Assembly1.[ClassLibrary1.MyVBClass].MyManager

And it works as expected, except when I use NULL:

DECLARE @MyManager nvarchar(1000)
EXEC @MyManager = dbo.GetManager NULL
PRINT @MyManager

It returns the value "Unknown" as it would have for any unknown DeptCode, as-programmed.

I'm of the theory it should have returned NULL without actually firing the function? Or is this only for non-CLR items... or stored procedures, not functions?

Transact SQL :: Database Null Value And String Null

Oct 27, 2015

We have a case where in we should show date based on conditions for e.g if we had a column defined as

col varchar(10) then we would show col as 'NULL' for some condition and actual value when no condition

Normaly date values are stored here e.g under col 20150901 .

Case 
when col>'20150901' then 'NULL'
else col
end as Derivedcol

Note this is an extract process and we are presenting data by pumping the data in a table .

Now there is another similar column -colz varchar(10)  which stores date but doesnt have case condition so whenever date has no value its shows null which is database null.

So whats the difference between database null and string null ?

 How can we show database null for the case condition instead of string "null"?

Checking For PK

Feb 10, 2004

Hi,

I want to assign a list columns to be the PK on a table. I don't know what this list of columns would be.How do I go about figuring that?

Sample Data

Col1...Col2...Col3..Col4
1...........2.......A......X
1...........2........B.....X
1...........2.......A......Y



As you can see Col1 & Col2 ONLY do not make up the PK. I need to include Col3 as well. My concern is I am not sure if I have a row like..
1...........2.......A......X reapeated lower down the order. So how do I figure the PK out?

Thanks

Null Result Returned Even Though IS NOT NULL Specified.

Apr 25, 2007

Hi guys,

I've got a query on a particular table returning an odd result:

SELECT DISTINCT WorkStation
FROM Invoice
WHERE WorkStation Is Not Null
ORDER BY WorkStation

This query returns the rows I'd expect plus a null row. This doesn't happen in databases at other sites, or in other tables at this site. The following query behaves as I'd expect returning only non-null AccountNumbers.

SELECT DISTINCT AccountNumber
FROM Suppliers
WHERE AccountNumber Is Not Null
ORDER BY AccountNumber

I can't reproduce these results on another site on a table of the same structure, or on another table at this site.

Any suggestions as to what might be going on?

Pertinent info:
---

Abridged result:

SELECT * INTO #Inv FROM Invoice

SELECT DISTINCT WorkStation

Does not reproduce this problem (and so is a probable fix) but the questions remains, what causes this?

TIA,

Default Constraints NULL / Not NULL

Value Is Null Remotely - Non Null Locally

Aug 15, 2006

ok here is a WIERD issue.

I've NEVER EVER had this issue, I have always done this and it works great both locally and remotely.

 

I have a table, which is a "customers" table.

I have a stored procedure which takes in parameters (name, address, password etc...) and returns me back, via a parameter declared as output - the customer ID.

I've always done this, and works great.

Now, this works fine locally.

 

IF I try to run this/do the exact same execution of commands (create a customer) remotely (where the database is stored, so copying everything from local to "over there") it does not work.

I get a DBNULL value back from the parameter, declared as an int output.

 

IF I copy and paste this Stored procedure Query/command into Query Analyzer and execute it (on the remote connection) and run it, giving it the exact same values as I do, it works perfect and returns me the correct value.

 

I've even dropped and recreated the stored procedure but makes no difference.

 

Any ideas why?

 

here is the proc....

 



CREATE PROCEDURE [dbo].[DoCreateNewCustomer] (
@theFirstName nvarchar(25),
@theLastName nvarchar(25),
@theAddress nvarchar(50),
@theCity nvarchar(15),
@thePostCode nvarchar(9),
@thePhoneNumber nvarchar(21),
@theMobilePhoneNumber nvarchar(21),
@theIPAddress nvarchar(25),
@thePassword nvarchar(50),
@theEmailAddress nvarchar(30),
@result int output
)
AS
SET @result = (SELECT [ID] FROM Customers WHERE emailAddress = @theEmailAddress)
IF @result IS NOT NULL 
 SET @result = -1
ELSE
BEGIN
 SET @result = @@IDENTITY
 INSERT INTO Customers (
 
 Firstname,
 Lastname,
 Address,
 City,
 Postcode,
 PhoneNumber,
 MobileNumber,
 IPAddress,
 [Password],
 EmailAddress
 
 )
 
 VALUES (
 
 @theFirstName,
 @theLastName,
 @theAddress,
 @theCity,
 @thePostCode,
 @thePhoneNumber,
 @theMobilePhoneNumber,
 @theIPAddress,
 @thePassword,
 @theEmailAddress
 )
 
END
GO


 

 

 

Any ideas why it does not work when calling the stored proc from either a web app, or through QA remotely but works fine when I run that command in QA or locally?

 

Again, if I do:

 

EXEC DoCreateNewCustomer { params } - the output result it gives me is DBNULL (if on remote connection)

If I do this locally, perfect

 

If I copy and paste pretty much the SP into QA and execute it on the remote connection, works great, and also locally.

Checking For Row Existence

Nov 1, 2006

Can someone show me some C# code for detecting if a SQL row exists or not?  This seems like a very typical action and I cannot for the life of me find a tutorial online that explains this step.  In my code I'm either going to INSERT or UPDATE a record.  I tried sending a SELECT command through a ExecuteNonQuery, but only got -1 as a response.  Apparently ExecuteNonQuery does not work with SELECT.  I then saw that T-SQL has an EXISTS keyword, but I cannot see anyway to use that from within C#.So...can anyone share the typical code they use to identify if a row exists or not within a database.  I guess I was execting there to be some method available to do this sort of thing.
