T-SQL (SS2K8) :: Select One Of Three Values That Are Not NULL?

May 6, 2014

I am working on some data that is JOINing to another table. Not a big thing. In the child table, there are different values for a single ID. I want to be able to select the Max ColorID that is Not Null, for each distinct CarID. The CarID is what I am joining the other table with. I need selecting the distinct row with the Max ColorID that is not Null. All this data is made up, so nothing looks logical in the design.

DECLARE @ColorList TABLE
(
CarID float
, ColorID int
)
INSERT INTO @ColorList
SELECT 1.55948815793043E+15, 9 UNION ALL
SELECT 1.55948815793043E+15, 27 UNION ALL

[code]....

So this would be the resultset:

1.55948815793043E+15, 27
1.62851796905743E+15, 27
1.51964586107807E+15, 9
1.55948815793043E+15, 27
1.47514023011517E+15, 5
1.64967408641916E+15, 27
1.51964586107807E+15, 9
1.56103326128036E+15, 27
1.49856249351719E+15, 9
1.5736407022847E+15, 6
1.64664602022073E+15, 27
1.51964244007807E+15, 27

How To Select NULL Values For My Report

But end user can not see these NULL value when he click drop down menu. I can not use Allow Null value option in report paramter , because I have used multi value option.
Is there any other way to select these NULL values?

SELECT With NULL Values In One Or More Of Selected Columns

Apr 10, 2008

Hello everyone,

I have a little problem here. I need to select data from multiple columns and multiple tables, some of those columns can have NULL value. I have tried few things, and havent find the right way so far. Problem that i am incountering is that when i run SELECT statment as it is right now, i dont get back results which match search parameters but have NULL value in one or more column in select statment. How can i fix this problem?


SELECT Person2role.person2roleID,Person.firstname, Person.lastname, Person.sex

FROM Person LEFT OUTER JOIN

Person2Role ON Person.personID = Person2Role.personID

WHERE (Person.firstname LIKE '%' + ISNULL(@firstname + '%', ''))

AND (Person.lastname LIKE '%' + ISNULL(@lastname + '%', ''))

AND (Person.sex = ISNULL(@sex, Person.sex))

This is a part of SELECT statment..just so you can get the idea of what i am doing..i have few more parameters


I am working with SQL Server 2005 Express Version

Thank you,

Alex

Won't Select Rows With Null Field Values

Aug 29, 2006

I cannot in the life of me understand what goes wrong here... In a webapplication (C#.NET) I traced an inability to retrieve existing records to SQL Server, where I cannot do the same either. The problem is that in the parameterized query, some fields can be null, and thus when the corresponding fields in the database record are null also, they should be selected. But this won't happen for some reason.

I wrote a test SQL statement that gives me the same bogus:

DECLARE @institution int, @collection int, @serialnr int, @subnr nvarchar(50)SET @institution = 1 SET @collection = 1SET @serialnr = 240 SET @subnr = NULLSELECT ID, Institution, Collection, SerialNumber, SubNumber, AccessionYear, Sagsnummer, DanekraeNr, TaxonIdentified, Stratigraphy, TypeStatus, PlacementRoom, PlacementCabinet, PlacementDrawer, UnitNotesFROM SpecimensWHERE (Institution = @institution) AND (Collection = @collection) AND (SerialNumber = @serialnr) AND (SubNumber = @subnr)
Now there is at least one row with corresponding fields values (1, 1, 240, null), but it won't be selected! What is wrong!?

NULL Values In A SELECT In Another SELECT

Jan 23, 2008

Hi,I have a query like this :SELECTx1,x2,( SELECT ... FROM ... WHERE ...UNIONSELECT ... FROM ... WHERE ...) as x3FROM ...WHERE ...The problem is that I don't want to return the results where x3 isNULL.Writing :SELECTx1,x2,( SELECT ... FROM ... WHERE ...UNIONSELECT ... FROM ... WHERE ...) as x3FROM ...WHERE ... AND x3 IS NOT NULLdoesn't work.The only solution I found is to write :SELECT * FROM((SELECTx1,x2,( SELECT ... FROM ... WHERE ...UNIONSELECT ... FROM ... WHERE ...) as x3FROM ...WHERE ...) AS R1)WHERE R1.x3 IS NOT NULLIs there a better solution? Can I use an EXISTS clause somewhere totest if x3 is null without having to have a 3rd SELECT statement?There's probably a very simple solution to do this, but I didn't findit.Thanks

Return NULL Values In SELECT Statement With INNER JOIN ?

Exclude NULL-Values Directly From ADSI-SELECT

Jun 28, 2007

Hi all,



is it possible to exclude empty records from an ADSI QuerySelect?



I got a query like




Code SnippetSELECT objectGUID FROM OpenQuery(ADSI, 'SELECT objectGUID FROM ''LDAP://DC=whatever,DC=domain,DC=org'' where objectClass = ''User'' AND objectCategory = ''Person''')



and would like to have it like




Code Snippet

SELECT objectGUID FROM OpenQuery(ADSI, 'SELECT objectGUID FROM ''LDAP://DC=whatever,DC=domain,DC=org'' where objectClass = ''User'' AND objectCategory = ''Person'' AND homeDirectory IS NOT NULL')

or


Code SnippetSELECT objectGUID FROM OpenQuery(ADSI, 'SELECT objectGUID FROM ''LDAP://DC=whatever,DC=domain,DC=org'' where objectClass = ''User'' AND objectCategory = ''Person'' AND NOT(homeDirectory = NULL) ')



The problem is that I can only perform a query like




Code SnippetSELECT objectGUID FROM OpenQuery(ADSI, 'SELECT objectGUID FROM ''LDAP://DC=whatever,DC=domain,DC=org'' where objectClass = ''User'' AND objectCategory = ''Person'' AND NOT(homeDirectory = '''')')



which results in the error

"Could not fetch a row from OLE DB provider 'ADSDSOObject'."



There are many objects which do have a homedirectory, though, and therefore should be fetched.



Any comments or hints on where my error hides?



I know I could go on fetching all objects and exclude the unwanted ones later on but I'd simply run into the limitation of data records LDAP would provide me with.

Thanks in advance!



Regards,

caracol

Compressing Multiple Rows With Null Values To One Row With Out Null Values After A Pivot Transform

Jan 25, 2008

I have a pivot transform that pivots a batch type. After the pivot, each batch type has its own row with null values for the other batch types that were pivoted. I want to group two fields and max() the remaining batch types so that the multiple rows are displayed on one row. I tried using the aggregate transform, but since the batch type field is a string, the max() function fails in the package. Is there another transform or can I use the aggragate transform another way so that the max() will work on a string?

NULL Values Returned When Reading Values From A Text File Using Data Reader.

Feb 23, 2007

I have a DTSX package which reads values from a fixed-length text file using a data reader and writes some of the column values from the file to an Oracle table. We have used this DTSX several times without incident but recently the process started inserting NULL values for some of the columns when there was a valid value in the source file. If we extract some of the rows from the source file into a smaller file (i.e 10 rows which incorrectly returned NULLs) and run them through the same package they write the correct values to the table, but running the complete file again results in the NULL values error. As well, if we rerun the same file multiple times the incidence of NULL values varies slightly and does not always seem to impact the same rows. I tried outputting data to a log file to see if I can determine what happens and no error messages are returned but it seems to be the case that the NULL values occur after pulling in the data via a Data Reader. Has anyone seen anything like this before or does anyone have a suggestion on how to try and get some additional debugging information around this error?

Null Values For Datetime Values Converted To '0001-01-01'

Mar 29, 2006

Hi

can somebody explain me how I can assign a NULL value to a datetime type field in the script transformation editor in a data flow task.
In the script hereunder, Row.Datum1_IsNull is true, but still Row.OutputDatum1 will be assigned a value '0001-01-01' which generates an error (not a valid datetime). All alternatives known to me (CDate("") or Convert.ToDateTime("") or Convert.ToDateTime(System.DBNull.Value)) were not successful.
Leaving out the ELSE clause generates following error: Error: Year, Month, and Day parameters describe an un-representable DateTime.




If Not Row.Datum1_IsNull Then

Row.OutputDatum1 = Row.Datum1

Else

Row.OutputDatum1 = CDate(System.Convert.DBNull)

End If



Any help welcome.

Use Order By But Want NULL Values As High Values

Nov 9, 2000

Hi,

My query "select blah, blah, rank from tablewithscores" will return results that can legitimately hold nulls in the rank column. I want to order on the rank column, but those nulls should appear at the bottom of the list

e.g.

Rank Blah Blah
1 - -
2 - -
3 - -
NULL - -
NULL - -

At present the NULLs are at the top of the list, but I do not want my ranking in descending order. Any suggestions?

Thanks

Integration Services :: SSIS Package - Replacing Null Values In One Column With Values From Another Column

Sep 3, 2015

I have an SSIS package that imports data from an Excel file, replaces any value in Excel that reads "NULL" to "", then writes the data to a couple of databases.

What I have discovered today, is I have two columns of dates, an admit date and discharge date column, and what I need to do is anywhere I have a null value in the discharge date column, I have to replace it with the value in the admit date column. 

I have searched around online and tried a few things using the Replace funtion in Derived columns but no dice so far.

But still I've to fetch my values. How do I do that?Thanks & Regards,Jahanzeb

SQL Null Values In VB

Apr 10, 2006

I have tried doing a search, as I figured this would be a common problem, but I wasn't able to find anything.  I know that my SP is functional because when I use VWD execute the query outside of the webpage, I get the correct results -however I have to ensure that a field is either entered, or set to <NULL>.  In my SET's I want it to use the wildcards.
What I want is to do a search (plenty of existing topics on that, however none were of help to me).  If a field is entered, then it is included in the search.  Otherwise it should be ignored.  In my VB I have the standard stored procedure call, passing in values to all of the parameters in the stored proc below:
CREATE PROCEDURE dbo.SearchDog@tagnum int,@ownername varchar(50), @mailaddress varchar(50),@address2 varchar(50),@city varchar(50),@telephone varchar(50),@doggender varchar(50),@dogbreed varchar(50),@dogage varchar(50),@dogcolour varchar(50),@dogname varchar(50),@applicationdate varchar(50)AS IF @tagnum=-1  SET @tagnum=NULL  SET @ownername = '%'+@ownername+'%'  SET @mailaddress = '%'+@mailaddress+'%'  SET @address2='%'+@address2+'%'  SET @city = '%'+@city+'%'  SET @telephone='%'+@telephone+'%'  SET @dogcolour='%'+@dogcolour+'%'  SET @dogbreed='%'+@dogbreed+'%'  SET @dogage='%'+@dogage+'%'  SET @doggender='%'+@doggender+'%'  SET @dogname='%'+@dogname+'%'  SET @applicationdate='%'+@applicationdate+'%'
 SELECT DISTINCT  * FROM DogRegistry WHERE (  TagNum = @tagnum OR  OwnerName LIKE @ownername OR  MailAddress LIKE @mailaddress OR  Address2 LIKE @address2 OR  City LIKE @city OR  Telephone LIKE @telephone OR  DogGender LIKE @doggender OR  DogBreed LIKE @dogbreed OR  DogAge LIKE @dogage OR  DogColour LIKE @dogcolour OR  DogName LIKE @dogname OR  ApplicationDate LIKE @applicationdate  ) AND TagNum > 0GO
I don't know why it is creating links inside my SP -ignore them.  TagNum is the primary key, if that makes a difference.
On the webpage, it ONLY works when every field has been filled (and then it will only return 1 row, as it should, given the data entered).  Debugging has shown that when nothing is entered it passes "".
Any ideas?

SUM When There Are Null Values.

Nov 2, 2007

Would this take care of null values in either a.asset or b.asset?

SELECT convert(decimal(15,1),(sum(isnull(a.asset,0))/1000.0)+(sum(isnull(b.asset,0))/1000.0)) as total_assets

What's throwing me off is that there are multiple a.asset or b.asset for each unique ID. It seems to work, but I'm not following the logic too well. If I were doing this in another language, I would loop through, summing a.asset and b.asset wherever it's not null for each unique ID.

Null Values

Jan 16, 2006

Hi,

How can I use "Derived Column" to check if a Datetime value is null or not and if null to insert  00/00/00 instead. ?

The background being that while using a "Derived Column" to change a Column from a (DT_DATE) to a (DT_DBTIMESTAMP) everytime I get a null value it see's it as a error.

And the column in particular has ~ 37 K blank / null fields so Im getting a lot of errors

So far I have tried to use something like

ISNULL([Column 34])

Or

SELECT ISNULL(ID, '00/00/0000') FROM [Column 34]

Or


SELECT ISNULL(au_id, '00/00/0000 00:00') AS ssn
FROM [Column 34

but none seems to work [Column 34] being the offending column.

What a normally use is just a simple "(DT_DBTIMESTAMP)[Column 34]"
in the expression column, which seems to work well, but here I get alot of errors

Any ideas?

Null Values

Apr 20, 2007

I set up a new SQL database file, in that file I allowed nulls, When I went through code to save the record, the exception is saying it doesnt allow nulls.



Before I get to involved with SQL, is it a bad practice to use nulls?



If it is what do you enter in place of the null value,

which will lead to more code, right?

Querying When Some Values Are Null

Mar 5, 2007

I wonder if someone out there can help me. I am writing an ASP application to query a MSSQL database. The users will be able to use one or all of 4 columns. There may be time when the columns are empty (null). How can I write a select query to ignore null values? A rough example of what I am talking about it below.
select * from table where value1='something' value2=<null> value3='something' value4=<null>
 I would like to ignore the null values so that in effect the statement would just do the following.
select * from table where value1='something' and value3='something'
 I realize my syntax is wrong but I think you get the idea. Any thoughts?

Selecting Null Values

Mar 12, 2007

I have a stored procedure that allows users to select addresses based on partially supplied information from the user.  My procedure seems to work fine in all but a few cases. If a user decides to select all the rows for a particular country the procedure below does not return any rows even if the rows exist.  I tracked this down to the fact that for Non US countries I set both the StateCode and Country Code to nulls. .

Finding NULL Values

Apr 10, 2007

I want to write a query to bring out any records in a table
where any of its fields contain a null value.  I could do it in this way:
 
select    *

from    
customers
where   name is
null
or         role
 is null
or         email
is null
u003c/p>u003cp styleu003d"margin:0cm 0cm 0pt">u003cfont faceu003d"Times New Roman" sizeu003d"3">u003cfont coloru003d"#000000">However I want to perform a similar function for a number of tables and the method above would mean more sql and maintenance.u003cspan>Â u003c/span>I was hoping there was a simple way to do the same thingu003cspan> ie find any rows with a blank fieldu003c/span>?u003cspan>u003cfont faceu003d"Arial" sizeu003d"2">Â u003c/font>u003c/span>u003c/font>u003c/font>u003c/p>u003c/span>u003c/font>u003c/div>",0]
);
D(["ce"]);

//--> 
However I want to perform a similar function for a
number of tables and the method above would mean more sql and maintenance.  I was hoping there was a simple way to
do the same thing ie find any rows with a blank
field?

Returning Null Values

Jun 4, 2007

I have a simple table on my webpage which shows data from my database.
It all worked fine apart from one part. I wanted the select statement to select only NULL values from a column, as these are classed as open queries. Once I have closed the query a 0 or 1 will automatically be posted and will no longer have a NULL value.
I have a simple select statement (which I will post on here when I log in with my work computer) and at the end I have a WHERE Column = NULL. I have also tried WHERE column <> 0.0 AND column <>1.0 and that did not work.
If I only did WHERE column <> 1.0, i only get the 0.0 results and none of the NULL results, but if I have no WHERE statement I get all the results including the NULL values.
