When exporting the results of a query to a file any values that are null are displayed as NULL in the file. Is there anyway to have them be blank instead? I looked around in the Studio but couldn't find anything that would do this globaly.
View 3 RepliesI 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?
View 12 Replies View RelatedI 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?

Hi,
my configuration file provides parameters that are used for an SQL query in my package. However, for these parameters it must be possible to pass NULL to the query.
This seems to be impossible in SSIS..? If the config file provides no value, the package uses a default value - and this default value can not be null.
Any suggestions?
Thanks a lot,

Hi,
I have the following problem: I'm connected to flat file source and trying to read data that is later inserted in an MS Access database. Everything wokrs fine instead of one thing - when I have null values in the flat file, I want those NULL values to be inserted in the MS Access db, instead of that what happens is that I actually get the default values for a column type from the flat file and later insert that defalut value. For example if I have a null value in an four-bite-signed-integer column of the flat file, I get 0 as value.
I thouth of solution using a "Derived Column" transformation which can transform the zeros into nulls, but decided to check with you guys if there is a smarter thing to do (for example to edit the flat file source to read the NULLs correctly).
Any advice is appreciated! Many thanks

Hello,
I'm trying to import some data from a spreadsheet to a database table from a package in integration services. The problem is that I see the data when I open the excel file but when I try to run my package , it doesn't insert any rows in the table and it finishes with a success status.
My excel file has some formulas to get the data from other worksheets. I added a Data Viewer and all I see is null values in every cell.
I need help...does anyone know what's wrong?
I am using a Excel Source to get the data from an excel file to sql server 2005 table. A couple columns are coming in a double precision float, but some values have characters in them, but those values are coming out as null, even though I changed the datatype from float to unicode string. Any inputs on resolving this will be much appreciated.
Thanks,

I have SQL Server 2012 SSIS. I have Excel source and OLE DB Destination.I have problem with importing CustomerSales column.CustomerSales values like 1000.00,2000.10,3000.30,NotAvailable.So I have decimal values and nvarchar mixed in on Excel column. This is requirement for solution.However SSIS reads only numeric values correctly and nvarchar values are set as Null. Why?

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

If I have a query such as
SELECT * FROM TABLE WHERE PARENT = NULL

Hi,
I have this problem with MS SQL Server.
I have this table 'Request' in which there's 2 fields 'RequestName' and 'DateSubmitted'.
The datatype for 'DateSubmitted' is datetimn.
I have to write a query to extract all the 'RequestName' that falls under each month based on the 'DateSubmitted'.
For example, the table 'Request' has 12 rows, each row ('DateSubmitted') with the month of the year. Like row1 = January, row2 = February etc.
For each month, I have to extract all the 'RequestName' for that month based on 'DateSubmitted' field.
My query is like this:
select RequestName, datename(month, DateSubmitted)as month
from Request where datename(month, DateSubmitted) = 'March'.
By right it should return just one row right?
Instead, it returned me all 12 rows, only one row with value 'March' and the other 11 rows with value 'NULL'. Even if the other 11 rows have value of other months, when i run the above query, it will return me null.
Any help is appreciated.
thanks a million.
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.
If I query sql server I get 10 results. But when I use if (myReader.Read()) I get only 7 results. I found that there was a Null field in the DB. I changed it and it worked.
The problem is I don't want to touch the database and set all null fields. There must be a way to get all results including the Null using sqlDataReader so that if (myReader.Read()) is used it does the right comparison.
// This code is called 10 times with a select * from where item="xxx"
P21Conn.Open();
SqlDataReader myReader = cmd.ExecuteReader();
if (myReader.Read()) {

easy question:
If I use "results to text" option when executing a query in Ms SQL Server Management Studio null value is inserted as 'NULL' string in the result. Is it possible to have blank ('') string instead of 'NULL' in the result in 2005 version.
It must be possible, but I could not find it in tools/options

Perhaps I was seeing things earlier, and it's really a minor thing, but when I display query results in Management Studio, isn't there a setting that turns the background of cells containing NULL to a pale yellow color? I could've sworn it used to do this, and I've searched high and low for a preference setting, but no joy.
Does this setting exist?

Hi All,
I receive the input file with some 100 columns and some 20k+ rows and I want to check the incoming input row is existed in the database or not based on 2 key columns. If the row is existed then I need to check all the columns (nearly 100 columns) values in input and the database are equal or not. If both are equal I need to treat them seperately if not there is a seperate logic. How Can I do that check for each row and for each column?
Basically the algorithm is like this, if the input file row is not existed in the database then treat that as new row else if the input row is existed in the database then check all the columns are equal or not. If all the columns are equal then treat that as existing row and do nothing else if some columns are not equal then treat this row seperately.
I found some thing to achieve the above thing.
1. Take the input row and check in the database.
2. If the row is not found in the database then treat it as new row.
3. If row is found in the database then
a) Take the source row and prepare a concatenated string for all the columns
b) Take the database row and prepare a concatenated string for all the columns
c) Find out the hash code for the 2 strings and then compare hash codes for equal.
The disadvantage of this is running a loop 2*m*n times where m is the number of rows and n is the number of columns. It should be done 2 times for input file row and database row.
Can anybody suggest a good method to do this?
What does the function "GetHashCode" for InputBuffer in method "Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)" will do?
Will it generates hash code based on all the columns values?
Pls clarify.
Regards
Venkat.
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?
