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.

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?

How Do You Handle Null DateTime Values From SQL Server?

Aug 17, 2005

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?

Null Values In Datetime Fields, Howto?

Jul 12, 1999

Hi,
When I try to insert a new record into a table that has a datetime field that allows nulls, a default 01/01/1900 date is inserted instead of null. I recreated the table and set the datatype to smalldatetime and I still get the error. What have I missed?

Mssql Won't Find NULL Values In Datetime Field??

Feb 13, 2007

Hi

I have a really simple query which i can't figure out why its not working. I have a table called 'ADMIN' which has a datetime field called 'date_edited'. Because the majority of records have never been edited, i have allowed null values and they are filled with 'NULL' in each record. How ever, when i try:

SELECT * FROM ADMIN WHERE date_edited = NULL

I get no records, but i can see and know i have hundreds! I know i'm doing somthing really stupid, but for life of me can't figure it out! :eek:

thanks

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?

Integration Services :: SSIS Reads Nvarchar Values As Null When Excel Column Includes Decimal And String Values

Dec 9, 2013

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?

CREATE TABLE [dbo].[Import_CustomerSales](
[CustomerId] [nvarchar](50) NULL,

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
Dan

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.

Multi-Select String Parameter Values Are Converted To N'Value1', N'Value2' In Clause When Report Is Run

Apr 14, 2008

I understand that Multi-Select Parameters are converted behind the scenes to an In Clause when a report is executed. The problem that I have is that my multi-select string parameter is turned into an in claused filled with nvarchar/unicode expressions like:

Where columnName in (N'Value1', N'Value2', N'Value3'...)

This nvarchar / unicode expression takes what is already a fairly slow-performing construct and just drives it into the ground. When I capture my query with Profiler (so I can see the In Clause that is being built), I can run it in Management Studio and see the execution plan. Using N'Values' instead of just 'Value1', 'Value2','Value3' causes the query performance to drop from 40 seconds to two minutes and 40 seconds. It's horrible. How can I make it stop!!!?

Is there any way to force the query-rewriting process in Reporting Services to just use plain-old, varchar text values instead of forcing each value in the list to be converted on the fly to an Nvarchar value like this? The column from which I am pulling values for the parameter and the column that I am filtering are both just plain varchar.

Thanks,

TC

SQL 2005 Bug? Cannot Create Full Text Index For VARBINARY Column That's Populated With Converted NVARCHAR Values

SQL 2005 Bug? Cannot Create Full Text Index For Varbinary Column That's Populated From Converted Nvarchar Values

Jul 11, 2007

Hi, I was wondering if any SQL Server gurus out there could help me...

I have a table I'm trying to apply a full text catalog to, however no results are ever returned due to the text column being cataloged being of varbinary(max) that's being populated from a converted nvarchar(max) value.

To re-create the problem quickly...

If I populate the column via
CONVERT(varbinary(max), 'test text')
then there is no problem, I get results as expected.

However if I populate the column via
CONVERT(varbinary(max), CAST('test text' as nvarchar(max)))
no results are ever returned.

Is this a bug with SQL Server 2005 Full Text Indexing? I'm happily creating full text catalogs when an nvarchar is not getting converted into a varbinary.

I'm setting the Document Type column to '.html' (I've tried changing this to '.txt' in case it was a fault with the html ifilter but the problem persists so I believe I can rule this out).

The reason I need to convert an nvarchar to varbinary is that the table holds multi-lingual text and I'm adding a html meta tag <META NAME="MS.LOCALE" CONTENT="ES"> to the beginning in order for the full text indexing word breaker to select the correct language to catalog the text with. The aim being to provide more relevant searches in users native languages (I've read a few articles that describe this technique, but it's the first time I've tried to apply it).

Any pointers / suggestions would be greatly appreciated. Cheers,
Gavin.

UPDATE: Below is a T-SQL script you can run to demonstrate the effect I'm experiencing...

Code Snippet

-- Create test database
CREATE DATABASE FullTextTest
GO
USE FullTextTest
GO

-- Create test data table
CREATE TABLE TestTable
(
pk UNIQUEIDENTIFIER NOT NULL CONSTRAINT tablePK PRIMARY KEY,
varbinarycol VARBINARY(MAX),
documentExtension VARCHAR(5),
)
GO

-- The below single entry WILL BE FOUND (the text source is being entered directly)
INSERT INTO TestTable (pk, varbinarycol, documentExtension) VALUES (NEWID(), CONVERT(VARBINARY(MAX),'<META NAME="MS.LOCALE" CONTENT="EN">test entry 1'), '.html')

-- The bellow two entries below WILL NOT BE FOUND (the text source is taken from an NVARCHAR(MAX) value)
INSERT INTO TestTable (pk, varbinarycol, documentExtension) VALUES (NEWID(), CONVERT(VARBINARY(MAX), CAST('<META NAME="MS.LOCALE" CONTENT="EN">test entry 2' AS NVARCHAR(MAX))), '.html')
INSERT INTO TestTable (pk, varbinarycol, documentExtension) VALUES (NEWID(), CONVERT(VARBINARY(MAX), CAST('<META NAME="MS.LOCALE" CONTENT="EN">test entry 3' AS NVARCHAR(MAX))), '.html')
GO

-- Create the full text catalog
sp_fulltext_database 'enable'
GO
CREATE FULLTEXT CATALOG TEST AS DEFAULT
GO
CREATE FULLTEXT INDEX ON TestTable (varbinarycol TYPE COLUMN documentExtension LANGUAGE 1033)
KEY INDEX tablePK
GO

-- NOTE: You might need to give the catalog a chance to build before running the script below.

-- Now do a search that SHOULD RETURN 3 ROWS of data, but ONLY 1 ROW IS RETURNED
SELECT CAST(varbinarycol AS NVARCHAR(MAX)) FROM TestTable WHERE CONTAINS(varbinarycol, 'test')

Millisecond Values Missing When Inserting Datetime Into Datetime Column Of Sql Server

Jul 9, 2007

Hi,
I'm inserting a datetime values into sql server 2000 from c#

SQL server table details
Table nameate_test
columnname datatype
No int
date_t DateTime

C# coding
SqlConnection connectionToDatabase = new SqlConnection("Data Source=.\SQLEXPRESS;Initial Catalog=testdb;Integrated Security=SSPI");
connectionToDatabase.Open();
DataTable dt1 = new DataTable();
dt1.Columns.Add("no",typeof(System.Int16));
dt1.Columns.Add("date_t", typeof(System.DateTime));
DataRow dr = dt1.NewRow();
dr["no"] = 1;
dr["date_t"] = DateTime.Now;
dt1.Rows.Add(dr);
for(int i=0;i<dt1.Rows.Count;i++)
{
string str=dt1.Rows["no"].ToString();
DateTime dt=(DateTime)dt1.Rows["date_t"];
string insertQuery = "insert into date_test values(" + str + ",'" + dt + "')";
SqlCommand cmd = new SqlCommand(insertQuery, connectionToDatabase);
cmd.ExecuteNonQuery();
MessageBox.Show("saved");
}
When I run the above code, data is inserted into the table
The value in the date_t column is 2007-07-09 22:10:11 000.The milliseconds value is always 000 only.I need the millisecond values also in date_t column.
Is there any conversion needed for millisecond values?

thanks,

Using NOT IN With Null Values

May 19, 2008

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

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?

Compare DateTime Values

Feb 2, 2006

guys this is kind of a biggie for me.
i've only used sql server to compare the Date Portion of date(s), not the whole string (mm/dd/yyyy hh:mi).
i have a table called Time_Check which has two fields with timestamps,
"TimeLastRun & TimeNextRun". i was trying to compare the Current TimeStamp that i pass from a vb.net form to a stored procedure and compare that DateTime to the TimeNextRun. I'd like to then Update the two Time Columns if rows are found. Should i maybe be using the DateDif Func if i know ahead of time how much time should be elapsed(say five minutes)?
Any Code help is appreciated

Create Procedure dbo.My_Time_Check
@myDate smalldatetime
as
select alertnumber,alertname,TimeLastRun,TimeNextRun
from time_check
where timeNextRun >= @myDate
--would like to update these two columns if rows are found

thanks again
this forum is the best

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?

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.

How To Deal With Null Values

Mar 1, 2008

Hi I have a table in my database and one of the columns is called 'Month'. Here only one month is inserted according to what the user selects from a dro down list.
WHat i want to be able to do is find the average of the column 'ScoreOut' on a month by month basis. My code works fine if th database contains at least one row with every month of the year represented. I run into problems when one of the months is not represented. here is my code:string month = "February";
SqlConnection myConn = new SqlConnection("Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\Database.mdf;Integrated Security=True;User Instance=True");String selectCommand = "Select AVG(CAST(ScoreOut as float)) from tblRound where Name = '" + lblName.Text + "' AND Month = '" + month + "'";
SqlCommand myCmd = new SqlCommand(selectCommand, myConn);SqlDataAdapter da = new SqlDataAdapter(myCmd);DataTable dt = new DataTable();

da.Fill(dt);
myConn.Open();
myCmd.ExecuteNonQuery();string info = String.Format("{0:0.00}", Convert.ToDecimal(myCmd.ExecuteScalar()));
myConn.Close();
lblHole2.Text = info;

Does anyone know how to get around this problem. If a month is not represented, i would like the label lblHole2.text to be equal to 0.

Null Values In Smalldatetime

Hi,

I am having a column subdate as smalldatetime.

The field can have null values. But I am not able to insert null values into the database.
i tried using subdate="". But it inserts some min value of my calendar popup.

Is there a way that i could insert null values into smalldatetime field of the SQl database.

Thanks,

Storing Null Values

Oct 4, 2004

I am retrieving a <NULL> value out of a SQL database, displaying it in a text box, then updating the database with the results of the text box.

I am using the following code to make the insert.

.Parameters("@BodilyInjuryPerson").Value = txtBodilyInjuryPerson.Text

When I have values for the text string, everything runs smoothly. However, when the database originally had a <NULL> or when I want to delete the currently existing value and replace it with a <NULL>, I get an error message stating... "Input string was not in a correct format".

Back in the old days, when I was using Random Access databases, you just inserted a Char(0). But that doesn't work any more.

Could somebody help me. I know there is a magic bullet, I just don't know what it is.

Hi all

Iam having some problems with null values

try
{
cmd.Parameters["@fmv"].Value = Convert.ToDecimal(TextBox13.Text);
}
catch
{
cmd.Parameters["@fmv"].Value =System.Data.SqlTypes.SqlDecimal.Null;
}

for Empty Textbox values
i am getting the following error,

System.Data.SqlTypes.SqlNullValueException: Data is Null. This method or property cannot be called on Null values.

My Database is allowed to accept null values.
