Modify ID Column
May 8, 2007I initially modified the column 'ID' from not allowing NULL to allow, and saved it. But now I will like to change it back to 'not allow'. But it gives me the following error message when I try to save my changes:
'Pages' table
- Unable to modify table.
Cannot insert the value NULL into column 'ID', table <databasename>.Tmp_Pages'; column does not allow nulls. INSERT fails.
The statement has been terminated.
Is there a way I can work around this?

How To Modify A Column Without Changing Data
Feb 26, 2007Hi,
I was wondering how to modify a column's properties, like its datatype or length.
I know I'm supposed to do something like this:
ALTER TABLE MyTable ALTER COLUMN MyColumn int(20)
My main concern is, what will the database do to all the data in the column, if the column used to be, say nvarchar(50)? Will I lose the data in the column if I change the datatype? And what if I had data in this column that was longer than 20 characters? Will the data now be truncated? What can I do to make sure that nothing happens to the data once I change the datatype?
Any help would be greatly appreciated! Thanks! =)

Modify A Column From Nvarchar(50) To A DateTime
Jun 3, 2007Hello,
I have a column that is a currently set as nvarchar(50) and is called DateEmployed.
There are over a hundred rows that contain dates which is in nvarchar format.
This column now needs to be changed to a DateTime datatype. (Don't ask me it was not set
to a dateTime when this was first designed - I wasn't here)
However, I have to change this column to a DateTime without destroying the data.
Is there any easy way to write some script or use studio management to change this.
Currently the data is displayed like this in this column dd/MM/yyyy i.e. 25/8/2007.
The method I am using to try and change this is by going to studio management clicking
modify on the column and changing the datatype from a nvarchar(50) to a DateTime.
I get this following error message:
- Unable to modify table.
Arithmetic overflow error converting expression to data type datetime.
The statement has been terminated.
Any suggestions would be most grateful,
Thanks,
Steve
Bulk Insert Task Failing On Data Type Conversion For A Destination Column Of Type Bit
Jul 6, 2006I am trying to use the Bulk Insert Task to load from a csv file. My final column is a bit that is nullable. My file is an ID column that is int, a date column that is mm/dd/yyy, then 20 columns that are real, and a final column that is bit. I've tried various combinations of codepage and datafiletype on my task component. When I have RAW with Char, I get the error included below. If I change to RAW/Native or codepage 1252, I don't have an issue with the bit; however, errors start generating on the ID and date columns.
I have tried various data type settings on my flat file connection, too. I have tried DT_BOOL and the integer datatypes. Nothing seems to work.
I hope someone can help me work through this.
Thanks in advance,

Error Trying To Modify Column With SQL Server Express 2005
Mar 6, 2008I am tearing my hair out with this!!
I have created a DB and up until yesterday I have been using SQL commands to add/remove tables, columns, constraints etc. However today when I attempt to modify the datatype of a column using
alter table Person modify Gender nchar(2)
I get this error
Msg 102, Level 15, State 1, Line 1
Incorrect syntax near 'modify'.
I can still add colums but get the same error if I try to drop them and I can amend the tables in any way via the Design view so I don't think it's permission related.
Any ideas greatly appreciated.
Transactional Repln,how To Modify The Width Of A Column Of A Table Which Is Replicated
Aug 3, 2006Hi All,
Is there a way by which we can modify the width of a column of a table which is being replicated without touching the ongoing transactional replication? This is for MSSQL2000 Transactional Replication.
I know (and successfully tried) that we can add a column to a table and that gets propaged to the replicate database and indeed the added column gets reflected there. How to add a column? sp_repaddcolumn or Right Click on the Publication-Properties and it shows a button to Add a Column.
This is what I have tried for modifying the width of a column of a table participating in Transactional Replication from varchar(10) to varchar(100)
MH (source) -> MH1 (Replicate)
The column €ścol1€? had width of varchar(10) and this was altered to varchar(100).
insert into MH..test_mh values(4,'abcdeabcdefff')
select * from MH1..test_mh
exec sp_dropsubscription @publication = N'MH', @article = N'test_mh', @subscriber = N'UKPBDRMTST2', @destination_db = N'MH1'
go
exec sp_droparticle @publication = N'MH', @article = N'test_mh'
go
alter table test_mh alter column col2 varchar(100) null OR
MH1..sp_help test_mh
exec sp_addarticle @publication = N'MH', @article = N'test_mh', @source_table = N'test_mh'
go
exec sp_addsubscription @publication = N'MH', @article = N'test_mh', @subscriber = N'UKPBDRMTST2' , @destination_db = N'MH1'
go
Needless to say, help would be apreciated -

How do I modify this so that just the category name is returned and not the parent cetegory. In other words, everything shows up just once. Arts and Entertainment, once, then on the next line Dance, then Music then the next parent category which is automotive.

Float Type Steals My Decimal Points And Money Type Kills My Query
Mar 28, 2008Happy Friday!
A while since I have posted a question, and this one is probably real easy.
I am trying to store numeric values from a php form in MSSQL 2000 database. However, the columns are set to float and if the value is 1.00, when entered into the table it is saved as 1
If I change the column type to money, the query fails, with an error message of conversion of datatype varchar to datatype money statement terminated.
anybody know what I need to do? do I need to do something in my query to specify that this is NOT varchar data?
Attempting To Modify Query For Performance...
Nov 29, 2007I've inherited an application that has a query that typically bombs out due to a deadlock in SQL Server 2005. I know where the resource contention is, and why the deadlock happens, and why SQL picks this query to fail, so that's all cool with me. My problem is that I'm in the process of modifying this query to be a little less resource intensive, and I'm getting two different result sets.
The original query is returning 1234 rows, and my first replacement query attempt is returning 930. My replacement query attempt is using a derived table (subquery) rather than copying into a temp table (as the original query is doing). I understand what the missing rows are and why they are not in the result set, so my question is What is it about my replacement query attempt that is so different from the original query?
I appreciate any advice anyone might have to offer.
Best,
B.

Open Table With Query To Modify Data
Jul 23, 2007In Enterprise Manager, I would right click on the table, choose Open Table and Query where I could select specific records and (most importantly) could alter data in a record by deleting the text, adding or over-typing.
In 2005 Server Management Studio I just cannot figure how to do this. I'm guessing that I need the 'Script Table as' option but then what?
I have managed to open selected data using the New Query and then Design Query in Editor, but the results only appear in a kind of view form and I cannot seem to alter any of the data entries, I get dotted lines around the selected field.
Please help, it seemed so much easier in 2000!
How Can I Set Constant Padding Between The Columns Of The Column Chart(stacked Column Sub-type)?
Aug 2, 2006Hi All,
I am working on a column chart type (stacked column sub-type) report.
Our customer requires us that the space(padding) between the columns should be a constant(including the space between the Y-axis and the first column). I know how to set the width of the columns, but I really don't know how to set the width of the space between them. The columns just varies the space between them automatically according to the number of the columns (the number of the columns is not certain).
Thanks a lot in advance!

View 7 Replies View Related*unsigned* 32-bit Column Type?
Aug 1, 2004I need to stored lots of unsigned 32-bit values. (I'm actually storing IPv4 addresses). These values will frequently exceed 2^31 but never exceed 2^32
My options are:
Use bigint. This is undesirable since this wastes 32-bits of space for every value.
Use int and use the negative value range to get full 32-bits worth of data. In C, it is easy and fast to cast a signed -1 to an unsigned 2^32-1. In SQL, it will be more expensive: Must cast to 64-bit and if val < 0 then val = 2^32 + val.
Is there a better alternative?
Is there a fast (binary) way to cast a value > 2^31 to a negative signed value?
DECLARE @value BIGINT
SET @value = 3000000000
SELECT CONVERT(INT, @value) -- causes error
SELECT CAST(@value AS INT) -- causes error
