Check For Null Values In Transact Sql
Aug 20, 2006I am using Visual Web Developer Express 2005 and SQL Server Express 2005.
I have set up a trigger that fires when an update has been performed on a specific table. The trigger checks to see if specific columns have been updated. If they have, then the trigger code is executed. This part works fine.
I am now trying to find a way to check if null values exist in either one of two field from the same table. If either field contains a null value, then I don't want the trigger code to be executed.
How can I check for null values and skip a block of code within my Transact Sql trigger.
Thanks.....
Transact SQL :: Null Values After Converting To Right Outer Joins

Cannot Update Records That Contain NULL Values!!!
Oct 19, 2006Hi, I am trying to use a formView with an update button to update individual records in an sql database. (when i click update it doesnt perform the update and just refreshes the page. ) One of the fields in my records is a NULL - this is also one of the fields that i need to update. When i manually go into the database and enter some data, and then go back to my form, it updates fine, but as soon as i delete the data from the field, it returns to NULL and im back to square one. Any Ideas on how to get around this problem?THanks

Nov 18, 2013I have a grid with checkbox, where users can select multiple rows and edit at the same time and save it to the DB. Now I have used a Footer Template with textbox in the gridview. So if I want to put similar data's for some particular rows at the same time in the grid, I select the multiple rows and try to put values in the footer template textbox and when I click on save, it saves successfully.
UPDATE QUERY:
"UPDATE [Test] SET [Name]='" + Name + "',[Designation]= '" + Designation + "', [City]= '" + City + "' WHERE EmpID='" + EmpID + "'";
Now here is the challenge, but even when I enter null values in the footer template textbox it has to save with the old values of the rows and not null values. I tried it and couldn't make it happen. So anything like putting the case for each column and mentioning like if null accept the old value and not null accept new value.

Update NULL Values Doesn't Work
Oct 2, 2007Hello everybody,
I can't perform an operation apparently very easy: set a field to a NULL value.
This is the db:
Microsoft SQL Server 2000 - 8.00.760 (Intel X86)
Dec 17 2002 14:22:05
Copyright (c) 1988-2003 Microsoft Corporation
Standard Edition on Windows NT 4.0 (Build 1381: Service Pack 6)
This is the table:
CREATE TABLE [ProgettoTracce] (
[ID_Progetto] [int] NOT NULL ,
[MisDifDef] [real] NULL ,
[MisDifMeas] [real] NULL ,
[MisDifAna] [real] NULL ,
[MisDifID] [real] NULL ,
[MisDifCV] [real] NULL
) ON [PRIMARY]
GO
This is qry:
UPDATE ProgettoTracce
SET MisDifDef = NULL
WHERE ID_Progetto = 3444
The qry has been performed with no error. Then I execute SELECT * FROM ProgettoTracce WHERE ID_Progetto = 3444 and I find the value I tried to overwrite with NULL. If I update with 0 (for example) it works.
Obviously this happens on the production db, because on the development db the update with NULL works fine.
No transaction is called, db options are the same on dbs...
What's happen? Have I to call an exorcist???
Thanks in advance for any help!

Transact SQL :: How To Update Subsequent Columns If Proceeding Column Is Not Null
Jul 7, 2015I've got a table with 6 fields :
EmployeeAccess
(MasterID, LoginID, AccessID, Storage1, Storage2, Storage3)
that needs to be updated using the data in the following spreadsheet
NewEmployeeAccessData
(ID, MasterID, AccessID1, LoginID1)
There is a 1:1 relationship between the two tables..I'm trying to code a pair of update statements on the EmployeeAccess table (1 for LoginID, 1 for AccessID) with the following logic:
If LoginID is NULL, then Update LoginID with new LoginID1 value,
If LoginID is not null, and Storage1 is NULL then Update Storage1 with New LoginID1 values
If LoginID is not null, and Storage1 is not NULL and Storage2 is NULL then Update Storage2 with New LoginID1 values
etc etc...
The same applies when trying to populate the AccessID column
If AccessID is NULL, then Update AccessID with new AccessID1 value,
If AccessID is not null, and Storage1 is NULL then Update Storage1 with New AccessID1 values
If AccessID is not null, and Storage1 is not NULL and Storage2 is NULL then Update Storage2 with New AccessID1 values
etc etc.
I have no control over the schema of this table so I'm trying to work the logic on how to update the columns in my table only if the corresponding column data is NULL, else update the next non NULL Storage column.
SQL Parameter Update Not Updating Changed Null/blank Values
Oct 24, 2006I am attempting to update a sql db using the update and parameter code in VB.net 2003 through MSDE for a web application. It updates changed data OK, but if the textbox value is deleted, the code does not update the sql db. I am new to this, and I'm sure it is something simple. Here is some sample code.

Compressing Multiple Rows With Null Values To One Row With Out Null Values After A Pivot Transform
Jan 25, 2008I 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?

Transact SQL :: Database Null Value And String Null
Oct 27, 2015We have a case where in we should show date based on conditions for e.g if we had a column defined as
col varchar(10) then we would show col as 'NULL' for some condition and actual value when no condition
Normaly date values are stored here e.g under col 20150901 .
Case
when col>'20150901' then 'NULL'
else col
end as Derivedcol
Note this is an extract process and we are presenting data by pumping the data in a table .
Now there is another similar column -colz varchar(10) which stores date but doesnt have case condition so whenever date has no value its shows null which is database null.
So whats the difference between database null and string null ?
How can we show database null for the case condition instead of string "null"?
NULL Values Returned When Reading Values From A Text File Using Data Reader.
Feb 23, 2007I 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'

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

Use Order By But Want NULL Values As High Values
Nov 9, 2000Hi,
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

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?

SQL Server 2008 :: Update Null Enabled Field Without Interfering With Rest Of INSERT / UPDATE
Apr 16, 2015If I have a table with 1 or more Nullable fields and I want to make sure that when an INSERT or UPDATE occurs and one or more of these fields are left to NULL either explicitly or implicitly is there I can set these to non-null values without interfering with the INSERT or UPDATE in as far as the other fields in the table?
EXAMPLE:
CREATE TABLE dbo.MYTABLE(
ID NUMERIC(18,0) IDENTITY(1,1) NOT NULL,
FirstName VARCHAR(50) NULL,
LastName VARCHAR(50) NULL,
[Code] ....
If an INSERT looks like any of the following what can I do to change the NULL being assigned to DateAdded to a real date, preferable the value of GetDate() at the time of the insert? I've heard of INSTEAD of Triggers but I'm not trying tto over rise the entire INSERT or update just the on (maybe 2) fields that are being left as null or explicitly set to null. The same would apply for any UPDATE where DateModified is not specified or explicitly set to NULL. I would want to change it so that DateModified is not null on any UPDATE.
INSERT INTO dbo.MYTABLE( FirstName, LastName, DateAdded)
VALUES('John','Smith',NULL)
INSERT INTO dbo.MYTABLE( FirstName, LastName)
VALUES('John','Smith')
INSERT INTO dbo.MYTABLE( FirstName, LastName, DateAdded)
SELECT FirstName, LastName, NULL

Basically it's converting certain row values to new column. Every PloicyNum will have 1001 to 1006 Fixed InsCode values as a group.
Rule-1: InsCode value 1001 should always mapped to 1005
InsCode value 1002 should always mapped to 1006
InsCode value 1003 should always mapped to 1004
Rule-2: For a policyNum, If any Inscode value is missed from the group values 1001 to 1006, still need to mapped with corresponding values as shown in Rule-1
In the above sample data..
for PolicyNum - 1ABC20 , group values 1003,1006 are missing
for PolicyNum - 1ABC25 , group values 1002,1003,1004,1005,1006 are missing

I have searched around online and tried a few things using the Replace funtion in Derived columns but no dice so far.
How To Correctly Update A Table Which Values Can Be Either Inserted/updated/deleted On Update?
Feb 16, 2006Hi SQL fans,I realized that I often encounter the same situation in a relationdatabase context, where I really don't know what to do. Here is anexample, where I have 2 tables as follow:__________________________________________ | PortfolioTitle|| Portfolio |+----------------------------------------++-----------------------------+ | tfolio_id (int)|| folio_id (int) |<<-PK----FK--| tfolio_idfolio (int)|| folio_name (varchar) | | tfolio_idtitle (int)|--FK----PK->>[ Titles]+-----------------------------+ | tfolio_weight(decimal(6,5)) |+-----------------------------------------+Note that I also have a "Titles" tables (hence the tfolio_idtitlelink).My problem is : When I update a portfolio, I must update all theassociated titles in it. That means that titles can be either removedfrom the portfolio (a folio does not support the title anymore), addedto it (a new title is supported by the folio) or simply updated (atitle stays in the portfolio, but has its weight changed)For example, if the portfolio #2 would contain :[ PortfolioTitle ]id | idFolio | idTitre | poids1 2 1 102 2 2 203 2 3 30and I must update the PortfolioTitle based on these values :idFolio | idTitre | poids2 2 202 3 352 4 40then I should1 ) remove the title #1 from the folio by deleting its entry in thePortfolioTitle table2 ) update the title #2 (weight from 30 to 35)3 ) add the title #4 to the folioFor now, the only way I've found to do this is delete all the entriesof the related folio (e.g.: DELETE TitrePortefeuille WHERE idFolio =2), and then insert new values for each entry based on the new givenvalues.Is there a way to better manage this by detecting which value has to beinserted/updated/deleted?And this applies to many situation :(If you need other examples, I can give you.thanks a lot!ibiza

Jul 8, 2015I have a table where table row gets updated multiple times(each column will be filled) based on telephone call in data.
Initially, I have implemented after insert trigger on ROW level thinking that the whole row is inserted into table will all column values at a time. But the issue is all columns are values are not filled at once, but observed that while telephone call in data, there are multiple updates to the row (i.e multiple updates in the sense - column data in row is updated step by step),
I thought to implement after update trigger , but when it comes to the performance will be decreased for each and every hit while row update.
I need to implement after update trigger that should be fired on column level instead of Row level to improve the performance?

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+'%'

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?
