I am trying to update a table that has a null value and keep getting a return of zero. I know that there are null values but cannot get the script to rcognize it. Example below
Use SimplexWFM
update per_Personnel_Info
set LAC5 = 'Default'
where LAC5 = '<NULL>'
Can anyone help?
If 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
FROM MYOTHERTABLE
Hi. I'm not such an expert in sql and I wanted to update a table's fields only if the value that im going to update it with is not null. How do I do that?
What I mean is something like:
---------------------------------------------------
Update database.dbo.table set
if(@newvalue !=null)
afield = @newvalue;
-------------------------------------------------
Really need your help on this. Thanks.
Here's my table:
----------------------------
Members
----------------------------
Subscriber | Name
----------------------------
Subscriber is a True/False value. However, some members have a NULL value in the Subscriber field. I'd like to go through all the members and update the Subscriber field to be 'False' if the value in there is NULL.

Hi, 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

I 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.
i want to display the max Date in place of NULL when Indicator is "1"
INPUT
Emp Num
Date
Indicator
1
Null

Hello - I have a column in a table (SQL 2005 EE) with a Data Type of smalldatetime and a Default Value of getdate(). When I insert a record from my webpage the new record contains the correct date via getdate(). However if I update the record from my webpage the date of the record then becomes NULL. Is this normal? Is there anything I can do about this from sql server? I am inserting/updating via an formview and ODS, using standard insert/update methods.
Cheers

Hello 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!

Hi guys, I have made several Access-based CMSs but now I am using SQL Server. I can read the records but my first attempts at writing are resulting in new records (with new ID) but all the fields are null.
I am posting the data from a form to the same page and an if /then statement catches the flag in the URL and runs the update script below. All the field names are correct.
if request.QueryString("add")<> "" then
Dim rsUpdateEntry
Set rsUpdateEntry = Server.CreateObject("ADODB.Recordset")
rsUpdateEntry.Open "SELECT * from generic_country_info" , oConn, 2, 3
rsUpdateEntry.AddNew
rsUpdateEntry.Fields("title1") = Request.Form("title1")
rsUpdateEntry.Fields("body1") = Request.Form("body1")
rsUpdateEntry.Fields("title2") = Request.Form("title2")
rsUpdateEntry.Fields("body2") = Request.Form("body2")
rsUpdateEntry.Fields("title3") = Request.Form("title3")
rsUpdateEntry.Fields("body3") = Request.Form("body3")
rsUpdateEntry.Fields("title4") = Request.Form("title4")
rsUpdateEntry.Fields("body4") = Request.Form("body4")
rsUpdateEntry.Fields("title5") = Request.Form("title5")
rsUpdateEntry.Fields("body5") = Request.Form("body5")
rsUpdateEntry.Fields("image1") = Request.Form("attach1")
rsUpdateEntry.Fields("image2") = Request.Form("attach2")
rsUpdateEntry.Fields("image3") = Request.Form("attach3")
rsUpdateEntry.Fields("image4") = Request.Form("attach4")
rsUpdateEntry.Fields("image5") = Request.Form("attach5")
rsUpdateEntry.Fields("country") = Request.Form("country")
rsUpdateEntry.Fields("dest_url") = Request.Form("dest_url")
rsUpdateEntry.Update
rsUpdateEntry.Close
Set rsUpdateEntry = Nothing
end if
Thanks

I am attempting to update a table that drives a report. The report is at the order level. An order can have several types of demand (revenue $): Ship and/or Backordered. When I update one of these demand fields on the report table, I would expect those orders that have that type of demand to update, and those orders that don't have that type of demand to remain at their current value ($0 in this example which is the table default). But what is happening is that orders that don't have that type of demand are changing to NULL. What am i doing wrong with my update statement that is causing this?
Code:
CREATE TABLE #sales(
OrdNo int,
StatusGrp varchar(10),
Demand decimal(10,2)
)
INSERT INTO #sales
VALUES (1,'Ship',100.00)
[Code] .....
Do I have to use condition split?, then union all?
if in script, I can use update from <tablename> Set column = isnull(column, 'NA'). It's so simple.
I'm also wondering can we run SQL Script against input dataset in a SSIS component?

Hi,I have an updatable DataGrid linked to a SQLDataSource in a web site developed using VS2005. Update works fine unless a value in the existing row is Null. Only one column in the database allows nulls.Putting a debug stop in the SqlDataSource1_Updating event, I checked the parameter value in the Immediate window and got the following result:?e.Command.Parameters(16){System.Data.SqlClient.SqlParameter}System.Data.SqlClient.SqlParameter: {System.Data.SqlClient.SqlParameter}DbType: Int32 {11}Direction: Input {1}IsNullable: FalseParameterName: "@original_FiresolveJobNo"Size: 0SourceColumn: ""SourceColumnNullMapping: FalseSourceVersion: Current {512}Value: NothingIs there a property I can set to generate a suitable Null check clause for the Update statement?Many Thanks,Keith.

Hey. I need to substitute a value from a table if the input var is null. This is fine if the value coming from table is not null. But, it the table value is also null, it doesn't work. The problem I'm getting is in the isnull line which is in Dark green color because @inFileVersion is set to null explicitly and when the isnull function evaluates, value returned from DR.FileVersion is also null which is correct. I want the null=null to return true which is why i set ansi_nulls off. But it doesn't return anything. And the select statement should return something but in my case it returns null. If I comment the isnull statements in the where clause, everything works fine. Please tell me what am I doing wrong. Is it possible to do this without setting the ansi_nulls to off??? Thank you
set ansi_nulls off
go
declare
@inFileName VARCHAR (100),
@inFileSize INT,
@Id int,
@inlanguageid INT,
@inFileVersion VARCHAR (100),
@ExeState int
set @inFileName = 'A0006337.EXE'
set @inFileSize = 28796
set @Id= 1
set @inlanguageid =null
set @inFileVersion =NULL
set @ExeState =0
select Dr.StateID from table1 dR
where
DR.[FileName] = @inFileName
AND DR.FileSize =@inFileSize
AND DR.FileVersion = isnull(@inFileVersion,DR.FileVersion)
AND DR.languageid = isnull(@inlanguageid,null)
AND DR.[ID]= @ID
)
go
set ansi_nulls on
I 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.
SqlConnection1.Open()
strSQLu = "UPDATE table1 " _
& "SET Field1Tag = @Field1Tag, Field2Tag = @Field2Tag " _
& "WHERE (Field1Tag = @Field1Tag) "
cmdCategoriesUpdate.CommandText = strSQLu
With cmdCategoriesUpdate
.Parameters("@Field1Tag").Value = txtFld1.Text
.Parameters("@Field2Tag").Value = txtFld2.Text
End With
cmdCategoriesUpdate.ExecuteNonQuery()
SqlConnection1.Close()
I'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.
update table1 set field1=null where id=1; commit;
where I can look for the user,who execute this statment?
It was 6.02.2007 or 7.02.2007.
All users connect using SQL Serwer Authentication.
It is test database and from 1 to 3 users connect to it, and submit not more then 10 SQl statmant per day.
Here is the sample data for table.
create table #sample (emp varchar(max),data1 varchar(max),data2 varchar(max), Rdate date)
insert into #sample (emp,data1,data2,rdate)
values('john','','',getdate())
insert into #sample (emp,data1,data2,rdate)
values('tony','','',getdate())
[Code] ...
I need to update the data1, data2 from yesterday or before but they should be non blank and non null and update to todays data.
It means, I can't update to 2015-03-12 values to 2015-03-13, as they are blanks or nulls.
So I need to go 2015-03-11 and check the values, if they are not blank , i need to update with todays values.
Before the update :
empdata1data2Rdate
john3/13/2015
tony3/13/2015
john3/12/2015
tony3/12/2015
johncd3/11/2015
tonyab3/11/2015
After the update:
empdata1data2Rdate
johncd3/13/2015
tonyab3/13/2015
john3/12/2015
tony3/12/2015
johncd3/11/2015
tonyab3/11/2015

Update Col B with Col A value if Col B is NULL in the Data File?
In my report i have CNAME parameter , which allows null value. I checked Allow null value check box in report parameter properties.
when i preview the report , it displays checked NULL check box beside CNAME parameter . I want to give some meaningful name(i.e.ALLCustomers) to this checkbox instead of NULL.
Is it possible through SSRS designer?
I have a flat file with the following columns
SampleID Rep_Number Product Protein Fat Solids
In the flat file SampleID and Product are populated in the first row only, rest of the rows only have values for Rep_Number, Protein, Fat, Solids.
SampleID and Product are blank for the rest of the rows. So my task is to fill those blank rows with the first row that has the sampleID and Product and load into the table.
I have a report that is run on a monthly basis with a default date of null. The stored procedure determines the month-end date that it should use should it be sent a null date.
The report works fine when I tell it to create a history entry; however, when I try to add a subscription it doesn't appear to like the null parameter value. Since I have told the report to have a default value of null it doesn't allow me to enter a value on the subscription page.
Now, I suppose I could remove the parameter altogether from the stored proc, but then the users would never be able to run the report for a previous time period. Can someone explain to me why default values aren't allowed to be used on subscriptions when they seem to work fine for ad hoc and scheduled reports? This is really quite frustrating as most of my reports require a date value and default to null so that the user doesn't have to enter them for the latest data.
An internal error occurred on the report server. See the error log for more details. (rsInternalError) Get Online Help
Key cannot be null. Parameter name: key
I run a stored procedure for which I have a return variable. The stored procedure returns the ID of a row in a table if it exists:
m_sqlCmd.ExecuteScalar();
The m_sqlCmd has been fed an SQLParameter with direction set to output.
When the stored proc returns, I want to test it. Now when there IS a row it returns the ID ok.
When the row doesn't exist, in my watch I have:
m_sqlParam.SqlValue with value {Null}
I can't seem to work out how to test this value out.
I've tried several things but none seem to work.
This line compiles ok, but the following runs into the IF statement as if the SqlValue is null??
if (m_sqlParam.SqlValue != null)....
{
// I'm here!! I thought the watch says this is null???
}
Sorry if this is obvious, but I can't work this one out!!
Looks like there was a fix and then I read this fix is not a fix. Does anyone know how this can be rectified? Does it mean that only Windows authentiation is the only way it works. The Software is over 2 years old, there are no excuses.
