Following SQL Statement is from BOL 7.0 and it doesn't return any data. But when I change the where clause to "WHERE advance IS NULL" it works. I am trying to do something like this in my own stored procedure. It works fine in 6.5 both ways. Is there any parameter to set? or any other problem. Thanks in advance.
SELECT title_id, type, advance
FROM pubs.dbo.titles
WHERE advance = NULL
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?

I am importing an excel spreadsheet into tables in a sql server database using dts. I have one row of information filled out in the excel spreadsheet, but when the dts runs, it imports the information plus 5 extra rows filled with nulls ino the table.
Does anyone know how to fix this?

Hello, i´m inserting values in a table defined as above,
/********
create table SERVICE_TYPE (
PK_TYPE numeric(8) not null IDENTITY,
TYPE nvarchar(32) not null unique,
DESCRIPTION nvarchar(256) null default(''),
USER_VISIBLE numeric(1)not null,
constraint PK_SERVICE_TYPE primary key (PK_TYPE)
)
go
**********/
these values are inserted throug ODBC with VC++,
in the case of the DESCRIPTION Column, i´m sending null strings CString(""). this value will be filled after.
What happens is that, when i query the database to show the records in this table, the database shows, for example:
PK_TYPE TYPE DESCRIPTION USER_VISIBLE
--------- ------ ------------------- -------------
1 1 (null) 1
i dont want to show the "(null)" value in the column DESCRIPTION, but a null string like ""
can anyone help me , thanks

If myDateTimeColumn contains a <NULL> value. How do you handle that when reading into a DateTime object in your code?DateTime myDate = Convert.ToDateTime(dr["myDateTimeColumn"]);Does not work, it throws: System.InvalidCastException: Object cannot be cast from DBNull to other types.
I am curious as to what others are doing to handle this?
I have two tables, a dates table and a values table. They are joined on the date column.The date table has a range, say from today as far as 20 days from now, incrementing by 1 day each row.The values table may have a row for a day, and may not. If the day has a value I want to display that value.If the day does not have a value in the values table I want to display the last known value.
I think this can be done with windowing functions in a set based manner but have not been able to work it out. I have done it procedurally but im not happy with that at all, and really want to see if this is possible in a set based manner.Below is some simplified code to allow testing with sample data.

Hello,I am trying to import a CSV file into my SQL Server database, this file was originally generated by another database table (on another server) with the same structure, the table contains two columns of real datatype with Allow Null Value setto true for those columns, the CSV file contains the value NULL for theses columns, I am facing a problem when importing this file. This may be because DTS tries to represent values as strings then to convert them to real datatype which results in transforming the value "NULL" to real, I receive an error message saying.Error during Transformation 'DirectCopyXform' for Row number 1. Errors encountered so far in this task: 1.
TransformCopy 'DirectCopyXform' conversion error: Conversion invalid for datatypes on column pair 8 (source column 'Col008' (DBTYPE_STR), destination column 'zip_longitude' (DBTYPE_R4)).
TransformCopy 'DirectCopyXform' conversion error: Conversion invalid for datatypes on column pair 7 (source column 'Col007' (DBTYPE_STR), destination column 'zip_latitude' (DBTYPE_R4)).How can I work around this problem? Any help would be appreciable
I am stuck on a query where I need to display all the month year values even if the corresponding count_booking values are NULL. The requirement is to display the 13 month year period from current date.
For e.g. if the date exists in the current month then starting from May 15 go all the way back to Apr 14.
My current query works in terms of displaying all the 13 months if the count_booking values exist for all the months. However, if some months are missing the values then those months don't show up.how to display all the months even if the values are NULL ? Query below:
SELECT COUNT(m.BOOKING_ID) AS count_booking, LEFT(DATENAME(MONTH, m.CREATE_DT), 3) + ' ' + RIGHT('00' + CAST(YEAR(m.CREATE_DT) AS VARCHAR), 2)
AS month_name

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?

I have an Excel spreadsheet (Excel 2003 format) with a column of values. The column is formated to General (although I've tried it formated to text). The values are alphanumeric. However, there are a few values that are completely numeric.
Example:
_ITEMNUMBER_
1-528
K214-5
184PR
45678
As can be seen, the last value is completely numeric. I am importing into a table with one column that is formated as nvarchar(50).
I use dtswizard.exe and do a simple import into the table and the alphanumeric values import just fine but anytime a value is completely numeric it has a NULL value in the table instead of the value that should be there.
I've tried changing the format of the column to nchar, char, etc, etc. Always comes in NULL.
Any ideas?

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.

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

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.Â
I have searched around online and tried a few things using the Replace funtion in Derived columns but no dice so far.Â
Hi, I ve a table, I want to fetch certain rows based on the value of a Column. That column is nullable, and contains NULL values.I used the following query,SELECT Col_A FROM TABLE1 WHERE SOME_ID = 1317 AND Col_B NOT IN (8,9) Here, Col_B contains NULL values too. I need to fetch all rows where Col_B is not 8 or 9.Now, if I use "NOT IN", it does not work. I tried reading on it and got to know why it does not work. Even "NOT EXISTS" does not help. But still I've to fetch my values. How do I do that?Thanks & Regards,Jahanzeb
View 6 Replies View RelatedI 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?
I am trying to retrieve data from two different tables. One of the tables has more than 20 columns some of which are null. I would like to retrieve data from both tables excluding the columns which have null values. How do I do this?
View 3 Replies View RelatedWould 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.
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?
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?
