I am getting this error: "Cannot insert the value NULL into column 'OrderID', table 'outman.outman.Contact'; column does not allow nulls. INSERT fails." -- But my value is not null. I did a response.write on it and it show the value. Of course, it would be nice if I could do a breakpoint but that doesn't seem to be working. I'll attach a couple of images below of my code, the error, and the breakpoint error.

Dear folks,
please tell me the query for altering a column from not null to null
Vinod
Hi all,
One of my columns is the table has some Null values, and I Would like to stop having NULL values into that column any more.
I know, If I alter the column to NOT NULL will throw me an error, since it does a batch update.
Is there any way to achieve this...
Thanks...

We have a database where many tables have a field that has to be lengthened. In some cases this is a primary key or part of a primary key. The table in question is:-
/****** Object: Table [dbo].[DTb_HWSQueueMonthEnd] Script Date: 09/25/2014 14:05:09 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO
CREATE TABLE [dbo].[DTb_HWSQueueMonthEnd](
[Code] ....
The script I am using is
DECLARE@Column varchar(100)--The name of the column to change
DECLARE@size varchar(5)--The new size of the column
DECLARE @TSQL varchar(255)--Contains the code to be executed
DECLARE @Object varchar(50)--Holds the name of the table
DECLARE @dropc varchar(255)-- Drop constraint script
[Code] ....
When I the the script I get the error message Could not create constraint. See previous errors.
Looking at the strings I build
ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] DROP CONSTRAINT PK_DTb_HWSQueueMonthEnd
ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] Alter Column [Patient System Number] varchar(10)
ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] ADD CONSTRAINT PK_DTb_HWSQueueMonthEnd PRIMARY KEY NONCLUSTERED ([Patient System Number] ASC,[Episode Number] ASC,[CensusDate] ASC)
WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
They all seem fine except the last one which returns the error
Msg 8111, Level 16, State 1, Line 1
Cannot define PRIMARY KEY constraint on nullable column in table 'DTb_HWSQueueMonthEnd'.
Msg 1750, Level 16, State 0, Line 1
Could not create constraint. See previous errors.
None of the fields I try to create the key on are nullable.
I receive this message when I try to run any report. The reportserver and reportservertempdb databases were upgraded using backup/restore from SQL2000 to SQL2005 on a separate server which is running RS2005 . Please help. Thanks

Â To summarize, I need a query that just shows which PID's have more than one unique GUID. A PID could have multiple GUID's that are the same, I'm looking for the PID's that have multiple GUID's that are different/unique.Â
Table1
GUID PID

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
I have a table with data in two columns, item and system. I am trying to accomplish is we want to compare if an item exists in 1, 2 or all systems. If it exists, show item under that system's column, and display NULL in the other columns.
I have aSQL Fiddle that will allow you to visualize the schema.
The closest I've come to solving this is a SQL pivot, however, this is dependent on me knowing the name of the items, which I won't in a real life scenario.
select [system 1], [system 2], [system 3]
from
(
SELECT distinct system, item FROM test
where item = 'item 1'
) x
pivot
(
max(item)

I have one table with two columns, GUID and PID and another table with three columns, GUID, LastName, and FirstName. For each unique PID, I need to find the PID's that have more than one GUID and then match that with their respective FirstName and LastName from the other table.

GUID PID
GUID1 PID1
GUID1 PID1
GUID1 PID1

I was querying to find the first non null address value using the COALESCE function.And I got the correct result.But then I jumped into another question and i.e what if I need to find the column name without knowing the column nameand just by using the column value.What I mean is this...My query was.....
SELECT COALESCE(AddressLine1,AddressLine2) AS [Addresss] FROM Person.Address
This is what I got.
Address#500-75 O'Connor Street#9900 2700 Production Way00, rue Saint-Lazare02, place de Fontenoy035, boulevard du Montparnasse081, boulevard du Montparnasse081, boulevard du Montparnasse084, boulevard du Montparnasse1 Corporate Center Drive1 Mt. Dell Drive
But then what if I just know the address of that person i.e #500-75 O'Connor Street..How am I suppose to retrieve that without knowing the column name.
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.Â
I have searched around online and tried a few things using the Replace funtion in Derived columns but no dice so far.Â
I want to modify this column:
codkey int NULL
to:
codkey int NOT NULL
How can I do that in SQL Server?
I think it must be very simple
Hi.I've read up on this, and have something that works, but I was wondering ifthere is anything I'm overlooking with this.Situation is:I have a bunch of tables.. I need to modify table2 as part of an upgrade of adatabase schema.I am using T-SQL scripts to do the trick which I'm writing myself.I need to add a new varchar(8) column that is not null to the primary key.I have a default I would like to use for the initial ddl modification.I want to get rid of the default after the modification is complete, but leavethe column not null for future operations...(Some if the code I'm using I took from one of Erlands posts.. hope I'm notabusing it).Here is the code I'm using now.. it basically adds the column 'institution_id'as not null along with a default.Then I jump through a couple of hoops trying to get rid of the default.Finally I setup the primary key again.I can only feel I'm supposed to be maybe using a constraint column with a nameto do this easier/more properly.set @dynamicsql = ' alter table institution_xref add institution_idvarchar(60) not null default ''' + @default_institution_id + ''' 'EXEC (@dynamicsql)set @dynamicsql = ' alter table institution_xref alter columninstitution_id varchar(60) not null 'EXEC (@dynamicsql)select @institution_iddefault = object_name(cdefault) from syscolumnswhere id = object_id('institution_xref') and name = 'institution_id'exec(' alter table institution_xref drop constraint ' +@institution_iddefault)set @dynamicsql = ' alter table institution_xref drop constraintinstitution_xref_pk 'EXEC (@dynamicsql)set @dynamicsql = ' alter table institution_xref with nocheck addconstraint institution_xref_pk primary key clustered (originalcode,institution_id) 'EXEC (@dynamicsql)thanksJeffJeff Kish

Hi,
I have a question whether set the default of column to null or non-null value as it is not easy to make a WHERE clause if the column is nullable.
Any suggestion?
It is issues like this that drive a programmer insane! I am trying to figure out if I am missing something here.
I have a query like this:
SELECT CL.DivisionId FROM CompanyLabels CL, BusinessRules B WHERE CL.CompanyLabelId = B.CompanyLabelId
In my table, DivisionId is nullable and equal to NULL.
In my VS.2005 Mobile 5 application, this line is giving me fits:
if (dr["DivisionId"] != null) { MessageBox.Show(dr["DivisionId"].ToString().Length.ToString()); divisionId = Convert.ToInt32(dr["DivisionId"].ToString()); }
DivisionId passes the null check and is blank. The message box returns "0" and of course, I get a FormatError on the conversion.
I have also tried DBNull in place of null. Is there a special System.Data.SqlServerCe NULL value in the SQL CE framework that I should be using? Am I completely forgetting something here?
Thanks!
Michael
Hello!
I have 80 tables in the database and I need to find in which table particular column exist. How can I do it shortly, without naming every table in my query?
Thank you.
I have more than 70 tables
How can i find the column name ( this column is the one of the column name from above tables)
pls help me
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

Hi
I have a table with the list of employee and 15 column with data type float or money , that represent the number of hours, airfare,gas,parking food, etc....
I have 2 choice:
-Put 0 as a default value for each column, like that I do not have to use coalesce when I do SUM for each column.
-Leave the default value null but I will have to use coalesce.
In term of performance, what is the best solution?
Thanks
Hello FriendsSuppose I'm designing one database table- ABC master and it has fields like field1, field2........field5. From these fields, Field1 is PK and 2 & 3 and mandatory. So while creating this table, is it necessary to specify the field 2 & 3 as NotNull in Null column.If I specify them as Null then does it effect aby thing. As i know that before saving the data to the database the programming logic checks whether the mandatory data entered or not?Reply back..Thanks

I have a table in which out of 20 columns, there will be data only in a few columns. So, I need to find those column names which have data in them. I was able to do it using the information_schema and using a cursor to loop through all the column names and find out which columns have data in them. But i need to know if there is a more efficient way of doing this without using the cursor. Can somebody please let me know how this can be done without using a cursor? Thank you.
I am trying to concatenate three columns and when one column might be NULL, the result set is NULL. I have set "concat null yields null" to false and the result is the same. Here is my code:

How do you alter a table to set a column which is currently int, to int not null?
I have already set all values to either 0 or 1.
Why can't I use:
Alter table myTable alter myCol int not null default(0)
I get a syntax error on the word default. If I remove "default(0)" then the command executes ok, but my Inserts don't work because there's no default value.
If no value is supplied on an insert for an int column that allows nulls, will the value be null or 0 ?
