Inserting Nulls? What's Wrong With This Expression?

Jan 9, 2008

I have a derived column transformation that inspects two columns for spaces and creates a third column, initialised with either '1' or 'X'.


However the transformation is failing with the error"

Cannot insert the value NULL into column 'TNV-INSERT1'


"

Here's the expression I'm using:
SUBSTRING(rt_tran_inv_text,1,255) != " " ? " X" : SUBSTRING(rt_tnv_narr_cr,1,30) != " " ? " X" : "1"

Neither of the source columns contain nulls. Any idea why it's trying to insert nulls into the new column?

Inserting Nulls In EM

Dec 21, 2005

Hi,

I've forgotten how to put a null value in a column of a table where a previous value existed before.

What I mean is if through EM, you look at the data (Open Table -> Return all Rows) and you see a value in a column that is nullable (for example, I want to change a column that has a 'ABC Company' to a NULL value).

How do you that - i've done it in the past ,but cannot remember

Thanks in advance

Inserting Nulls Into The Db

Mar 27, 2002

I'm using ADO.NET and have noticed that it is somewhat more difficult to send/receive nulls to/from the database. What are the benefits (if any exist) with storing a null value in the db as opposed to a default value?

In particular, do you save any space by storing a null opposed to a zero or 01/01/1900? Are the nulls faster for searching/comparing when querying the db?
Basically I'm just wondering if storing nulls is really the best practice and why, so that I know whether it's worth the effort in .NET to transform my variables into a null-happy form.

Any facts/opinions are appreciated,
Inge

Inserting Nulls Into A Temp Table

Mar 3, 2008

I'm trying to insert any null values into a temp table. I'm storing the ixo_rlt_code as OldRole, and 'Other' as NewRole. I need both the ixo_rlt_code as OldRole and 'Other' as NewRole in the temp talbe in order to run an update I'm writing.

I know a case statement isn't necessary here, but this section is only one small part of a larger script, so I just used it to be consistent, and it will be easier to make any future changes this way. Below is my code and the error message I'm getting...


select
ixo_key,
ixo_title as Title,
ixo_rlt_code as OldRole,
CASEWHEN ixo_title is null
or ixo_title = ''
or ixo_title = ' '
or ixo_title = ' ' THEN 'Other'

END as NewRole


from
co_customer (nolock)
join co_individual_x_organization (nolock) on ixo_key = cst_ixo_key --and ixo_delete_flag = 0
where
cst_delete_flag = 0
and cst_type = 'Individual'
and ixo_rlt_code is null


This is the Error Message I get:
Server: Msg 515, Level 16, State 2, Line 1095
Cannot insert the value NULL into column 'NewRole', table 'tempdb.dbo.#temp_______________________________________________________________________________________________________________00000001698C'; column does not allow nulls. INSERT fails.

Inserting Nulls In To Table Conflicting With Rule

Jan 15, 2007

Hi,I basically have two tables with the same structure. One is an archiveof the other (backup). I want to essentially insert the data in to theother.I use:INSERT INTO table ( column, column .... )SELECT * FROM table2Now, table2 has a rule on various columns:@CHARACTER IN ('Y','N')but the column allows nulls, in the design view is says so anyway.When I run this query I get:A column insert or update conflicts with a rule imposed by a previousCREATE RULE statement. The statement was terminated. The conflictoccurred in database 'database', table 'table', column 'column'.The statement has been terminated.Obviously, I've changed the names of everything.The only data in those columns which could possibly conflict with therule is the NULL value. Any ideas why this doesn't work?Thanks.

Problems Inserting Data- Am I Doing Something Wrong?

Mar 23, 2007

I am having problem inserting data obtained from a adhoc sql query. Am I doing something wrong here (the select statement in below mentioned query works fine)
Insert into customer(CustomerID, LastName, FirstName, BillingAddress, City, State, Country, Zipcode, PhoneNumber, EmailAddress)
select CustomerID,(left(ContactName, charindex(' ', ContactName)-1)) as LastName,
(right(ContactName, charindex(' ', reverse(ContactName))-1)) as FirstName,
Address, City,Region,PostalCode,Country,Phone from Northwind.dbo.Customers
 
I am just doing it this way since Customer's name (both last name & first name ) are stored in a single column in Northwind database. I want to break it into two columns...The reason I am trying to get this to work is...it would be less of a work for me in inserting test data for my applicationAny help would be of great

Grouping By Month In Common Table Expression Counts Wrong

Sep 26, 2012

I'm using CTEs to try and get the totals of two different criteria queries that I want to group by Month depending on the associated Inquiry Date. Here is what I have right now;

Code:
;With CTE(total, InitDate) as
(
SELECT count(Inquiry.ID), Inquiry.Date from Inquiry
Inner Join Inquirer on Inquirer.ID = Inquiry.InquirerID_fk
Left Join Transfer on Transfer.TransferInquiryID_fk = Inquiry.ID
WHERE (Inquiry.Date >= '3/1/2012' AND Inquiry.Date <= '9/26/2012' AND Inquiry.Date IS NOT NULL)
AND (Inquirer.Program = 'Res. Referral Coord.')AND TransferInquiryID_fk IS NULL
Group By Inquiry.Date

[code]...

I get 170 for InitCount, but for TransCount I only get 19, not 26. I assume it is with my left outer join statement grouping but I am not sure how I would change this to get the proper counts. All I want to do is group the values together depending on the month they were done in.

Wrong Evaluation Of A Variable With Expression In Case It Is Used Simultaneously By Several Tasks

Aug 22, 2007



Hi guys,

I have experienced problem while trying to use variable with expression based on several other variables in tasks running parallel.

The details are as following:

There is a SSIS package with simple Control flow: one Script Task which actually do nothing and two Execute Process Tasks, they run after Script Task in parallel. Then there are three simple (EvaluateAsExpression = False) string variables ServerName, Folder and JobNumber with values ServerName = €œ\test€?, Folder = €œtest€? and JobNumber = €œ12345€?. And there is one variable FullPath with expression @[User:: ServerName] + "\" + @[User::Folder] + "_" + @[User::JobNumber]. All the variables are of the Package scope. Then in Execute Process Tasks I have similar expressions based on FullPath variable: Execute Process Task 1 has expression @[User::FullPath] + "\date.bat" and Execute Process Task 2 has @[User::FullPath] + "\time.bat" one. As you understand these expressions define what exactly task should execute.

Then I€™m going to execute package from command line so appropriate XML configuration file has been created. The file contains following values for variables described above: ServerName = €œ\LiveServer€?, Folder = €œJob€? and JobNumber = €œ33091€?.

After series of consequent executions I have got following log file:

€¦ Execute Process Task 1€¦ Executing the process €œ\LiveServerJob_33091date.bat€?

€¦ Execute Process Task 2€¦ Executing the process €œ\Test est_12345 ime.bat€?



€¦ Execute Process Task 1€¦ Executing the process €œ\Test est_12345date.bat€?

€¦ Execute Process Task 2€¦ Executing the process €œ\LiveServerJob_33091 ime.bat€?



€¦ Execute Process Task 1€¦ Executing the process €œ\LiveServerJob_33091date.bat€?

€¦ Execute Process Task 2€¦ Executing the process €œ\Test est_12345 ime.bat€?



€¦ Execute Process Task 1€¦ Executing the process €œ\LiveServerJob_33091date.bat€?

€¦ Execute Process Task 2€¦ Executing the process €œ\LiveServerJob_33091 ime.bat€?



€¦



As you can see one of Execute Process Tasks usually receive correct value of the expression (based on values of variables from the configuration file) while another - incorrect one (based on €œdefault€? values of variables set directly in package). Sometimes wrong value appears in Task 1, next time in Task 2. Situations when both expressions in tasks evaluated correctly are very rare.

Then if you add some more Execute Process Tasks with similar expressions in the package (for ex. simply by copying existing tasks) you€™ll get a good chance to catch error like this:



OnError,,,Execute Process Task 1,,,8/17/2007 2:07:12 PM,8/17/2007 2:07:12 PM,-1073450774,0x,Reading the variable "User::FullPath" failed with error code 0xC0047084.



OnError,,,Execute Process Task 1,,,8/17/2007 2:07:12 PM,8/17/2007 2:07:12 PM,-1073647613,0x,The expression "@[User::FullPath] + "\time.bat"" on property "Executable" cannot be evaluated. Modify the expression to be valid.



Seems variable with expression FullPath is locked during evaluation by one of the parallel tasks in such a way that another task can€™t read it value correctly. Can someone help me with the issue? Maybe there are some options I missed which could prevent such behavior of application? Please let me know how I can make the package work correctly.

Common Table Expression (CTE):How To Delete A Wrong CTE That Is In SQL Server Management Studio Express (SSMSE)?

Feb 25, 2008

Hi all,

I ran the following CTE sql code:


Use ChemDatabase

GO

WITH PivotedTestResults AS

(

SELECT TR.AnalyteName, TR.Unit,

Prim = MIN(CASE S.SampleType WHEN 'Primary' THEN TR.Result END),

Dupl = MIN(CASE S.SampleType WHEN 'Duplicate' THEN TR.Result END),

QA = MIN(CASE S.SampleType WHEN 'QA' THEN TR.Result END)

FROM TestResults TR

JOIN Samples S ON TR.SampleID = S.SampleID

GROUP BY TR.AnalyteName, TR.Unit

)

SELECT AnalyteName, UnitForConc,

avg1 = abs(Prim + Dupl) / 2,

avg2 = abs(Prim + QA) / 2,

avg3 = abs(Dupl + QA) / 2,

RPD1 = abs(Prim - Dupl) / abs(Prim + Dupl) * 2,

RPD2 = abs(Prim - QA) / abs(Prim + QA) * 2,

RPD2 = abs(Dupl - QA) / abs(Dupl + QA) * 2

FROM PivotedTestResults

GO

//////////////////////////////////////////////////////////////////////////////////////
I got the following errors:

Msg 207, Level 16, State 1, Line 9

Invalid column name 'Unit'.

Msg 207, Level 16, State 1, Line 3

Invalid column name 'Unit'.

////////////////////////////////////////////////////////////////////////////////////////////////////////////////

I guess that I had "Unit" (instead of "UnitForConc"), when I executed the sql code last time!!!???
How can I delete the old, wrong CTE that is already in the ChemDatabase of my SSMSE?

Please help and advise.

Thanks in advance,
Scott Chang

Do Not Keep NULLS Using SSIS Bulk Insert Task - Insert Empty Strings Instead Of NULLS

May 15, 2008

I have two SSIS packages that import from the same flat file into the same SQL 2005 table. I have one flat file connection (to a comma delimited file) and one OLE DB connection (to a SQL 2005 Database). Both packages use these same two Connection Managers. The SQL table allows NULL values for all fields. The flat file has "empty values" (i.e., ,"", ) for certain columns.

The first package uses the Data Flow Task with the "Keep nulls" property of the OLE DB Destination Editor unchecked. The columns in the source and destination are identically named thus the mapping is automatically assigned and is mapped based on ordinal position (which is equivalent to the mapping using Bulk Insert). When this task is executed no null values are inserted into the SQL table for the "empty values" from the flat file. Empty string values are inserted instead of NULL.

The second package uses the Bulk Insert Task with the "KeepNulls" property for the task (shown in the Properties pane when the task in selected in the Control Flow window) set to "False". When the task is executed NULL values are inserted into the SQL table for the "empty values" from the flat file.

So using the Data Flow Task " " (i.e., blank) is inserted. Using the Bulk Insert Task NULL is inserted (i.e., nothing is inserted, the field is skipped, the value for the record is omitted).

I want to have the exact same behavior on my data in the Bulk Insert Task as I do with the Data Flow Task.

Using the Bulk Insert Task, what must I do to have the Empty String values inserted into the SQL table where there is an "empty value" in the flat file? Why & how does this occur automatically in the Data Flow Task?

From a SQL Profile Trace comparison of the two methods I do not see where the syntax of the insert command nor the statements for the preceeding captured steps has dictated this change in the behavior of the inserted "" value for the recordset. Please help me understand what is going on here and how to accomplish this using the Bulk Insert Task.

Reporting Services :: Running Value Expression Within Lookup Expression In SSRS?

Oct 28, 2015

I have created 1 report with 2 datasets. This report is attached to the 1st dataset.For example,1st one is "Smallappliances", 2nd is "Largeappliances".

I created a tablix and, the 1st column extracts Total sales per Sales person between 2 dates from 1st dataset (Small appliances). I used running values expression and it works fine.

Now, I would like to add another column that extracts Total sales per sales person between 2 dates from 2nd dataset (Large appliances). I am aware that I need to use Lookup expression and it is giving me the single sales value rather than the total sales values. So, I wanted to use RunningValue expression within lookup table to get total sales for large appliances.

This is the lookup expression that I added for the 2nd column.

=Lookup(Fields!salesperson.Value,Fields!sales_person.Value,RunningValue(Fields!sales_amount.Value,
sum, " sales_person"),
"Largeappliances").

I get this error when I preview the report.An error occurred during local report processing.The definition of the report is invalid.An unexpected error occurred in report processing.

(processing): (SortExpression ++ m_context.ExpressionType)

Can someone tell me what to do if several NULLS are showing up within tables. Is there an easy step to locate all NULLS and delete them within the table?

Can someone provide detailed infromation on how to delete NULLS within tables. I'm new o the SQL side so I hope I have explained what it is that I'm looking to do. Our in house programmer said that the NULLS maybe causing a problem with the software communicating with the SQL Server software.

NULLS And ''

Feb 6, 2007

Hi,I don't have any specific details as I do not really understand whythis is happening but we have a customer database that we have beenusing and queries on text fields have begun returning empty stringvalues instead of NULL.So for example:SELECT TAB1.DESCRIPTIONFROM TABLE1 TAB1WHERE TAB1.DESCRIPTION IS NOT NULLORDER BY 1may have returned 50 records in the past (purely an example). It isnow returning an additional record first that appears just to be ''.Now I am not too sure where to begin looking into this. ODBCconnections, collation settings? I just am not sure where to begin.The column will not have had '' inserted into it; therefore it shouldbe NULL.I have posted this mainly so I can see if anybody else has seen thissort of behaviour - I cannot see why this has suddenly happened.The collation setting on our server is different to that of thecustomer DB, but this shouldn't make a difference should it?If anybody has any ideas then I can post some more information.Thanks,Paul

Are Nulls Bad

Jul 20, 2005

HiI am probably going to regret asking this because I'm sure you are going totell me my design is bad 8-) ah well we all have to learn....anywayI often use Nulls as a marker to see if certain tasks have been completed.A typical example would be a column say invoice_valuewhen new work is entered and a new record is appended, I leave theinvoice_value column as NULL, so if I want a View for uninvoiced work Icheck for the invoice_value being equal to NULL, and alternatively if I wantinvoiced work, I check for not null. I did it this way to save putting inanother column that needed to be set to TRUE or FALSE. (I do similar thingselsewhere aswell)so far everything seems to work OK but reading some old stuff on Google Iget the feeling that NULLS should be left alone, have I done wrong?many thanksAndy

NULLS

Nov 26, 2007

Hello all

I have a colunm - Datatype : nvarchar - Contains: Numeric, characters, strings, date and NULLS

I am getting a the value of each row of this colunm in a variable say @var1

Now I am trying to do some functionalities depending on this variable.

The requirement is if this variable is not null I need to do some stuff.

So I write simple query:

IF (@var1 IS NOT NULL)
BEGIN
......
END

when i am doing this I get an Error:


Error converting data type nvarchar to numeric.

realizing this I change the condition to
IF ( LEN (@Var1) > 1)

then
IF (LEN (@Var1) <> 0)

but no use. I get the same error.

I even use cast
I get the error

Conversion failed when converting the nvarchar value 'null' to data type int.


IF(CAST (@OldValue AS INT)IS NOT NULL)
OR

IF(LEN (CAST (@OldValue AS INT)) <> 0)


Can somebody help in guiding the best practice to do this?

Column Does Not Allow Nulls

Nov 4, 2007

 Hi,This should be straight forward, but I've searched high and low on the net.I have a FORM which allows me to INSERT data, SQL Server 2005 backend. I populate the all the mandatory fields. But when I click on the Insert button, it won't let me save and says:Column 'PERSONAL_ID' does not allow nullsI'm
using tableadapters, business logic layers etc. and pausing clearly
shows that the values from the form are being passed to the procedure
that I have created "AddNewRecord". And PERSONAL_ID is definitely not
NULL! It fails on Line 971: Me.Rows.Add(row)PERSONAL_ID
is a primary key which I generate. The pause also shows that for
PERSONAL_ID it says " {"Conversion from type 'DBNull' to type 'String'
is not valid."}Function AddNewRecord looks like this:<System.ComponentModel.DataObjectMethodAttribute(System.ComponentModel.DataObjectMethodType.Insert, True)> _
Public Function AddNewRecord(ByVal PERSONAL_ID As String, ByVal SURNAME
As String, ByVal CHRISTIAN_NAME As String, ByVal SEX As String, _
ByVal FAMILY_POSITION As String, ByVal FAMILY_ID As String, ByVal
ADDRESS_1 As String, ByVal ADDRESS_2 As String, _ ByVal ADDRESS_3

Need To Get NULLs Into The Action..

Mar 11, 2008

I have the following query:
 SELECT tblArticleCategory.ACategoryID, IsNull(ParentCategory, '') + IsNull( ' > ' + ACategoryName, '') AS Category from tblArticlecategory
RIGHT OUTER JOIN (SELECT ACategoryName as ParentCategory, ACategoryID from tblArticleCategory WHERE AParentID is null AND aActive=1) AS Parent
on parent.ACategoryID = tblArticleCategory.AParentID
WHERE tblArticleCategory.AActive=1ORDER BY Category
This produces an ordered list of the parent categories and subcategories from the table as long as there is a subcateogry directly below one of the parent categories. If there isn't one directly below the parent category, the parent category is dropped from the list. None of the parents with the NULLS back to back are in the list.

How do I fix the query so that Automotive, Business, Cancer and Communications are included in the list?

Allow Nulls Cannot Be Changed

Apr 9, 2003

I have a table as part of a replicated database where i need to change the allow nulls value (set it to not allow nulls) but when i try to save the table i get this error.

'CONTACTS' table
- Unable to modify table.
ODBC error: [Microsoft][ODBC SQL Server Driver][SQL Server]Cannot drop the table 'dbo.CONTACTS' because it is being used for replication.

will i have to stop replication to make the change or is it worse and i have to delete the publication and start all over again?

How To Sort NULLs?

Jul 13, 2004

Hi All,

I have a table with 3 columns. Product, Location and Value. The data looks like this:

NULL NULL 100
Atlanta NULL 50
Atlanta Cookie1 30
Atlanta Cookie2 20
Dallas NULL 120
Dallas Cookie1 80
Dallas Cookie2 40

This table gets filled with a Groupby with Rollup option. The NULLS show subtotals/total. Is there a way to build a query that returns the results with NULLs at the bottom of each section like:


Atlanta Cookie1 30
Atlanta Cookie2 20
Atlanta NULL 50
Dallas Cookie1 80
Dallas Cookie2 40
Dallas NULL 120
NULL NULL 100

Thanks,

Shab
