how to modify the length of a column In sql server 6.5
example:
from varchar(10) to varchar(20)
is there any way or a tool to identify if in procedure the Parameter length was declarated less than table Column length ..
I have a table
CREATE TABLE TEST001 (KeyName Varchar(100) ) a procedure
CREATE PROCEDURE SpFindNames ( @KeyName VARCHAR(40) )
AS
BEGIN
SELECT KeyName FROM TEST001
WHERE KeyName = @KeyName
END
KeyName = @KeyName
Here table Column with 100 char length "KeyName" was compared with SP parameter "@KeyName" with length 40 char ..
IS there any way to find out all such usage on the ALL Procedures in the Database ?
Hello Friends,
I am working on a web application and using Sql Server 2005 as a Databasew. I want to define a variable with the datatype as defined in the database. Let me give an example.
In my web say there is a field "First Name" and for that I had created a TextBox "txtFirstName" in code behind to get this value I have defined a variable
String getFirstName;
Now this variable has to be stored into the table "Person" into the column "FirstName" which is of type "nvarchar" and having length "20" So I want to get this length programatically so that I can assign this number (20) to the maxlength property of the textbox "txtFirstName" so that in future if the legth of the database column changes it should no be needed to change in code also.
Caqn it be done? If yes please let me know.
Thanks & RegardsGirish Nehte
I 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.
Below is a SQL statement that shows what columns belong to a certain view. My next question is how can I get a third column that shows the column type ?
VARCHAR(100), or UNIQUEIDENTIFIER or INTEGER or TEXT or NVARCHAR(256) or ........????
select top 100 a.name, b.name, from sys.views a inner join sys.columns b
on a.object_id = b.object_id where a.name like '%Case_Times%'
I have a table called test with 4 fields namley studentname, Mark1, Mark2, total (formula column).
Created table test in the following structure,
create table test (studentname varchar(50), Mark1 numeric, Mark2 numeric, total as ([Mark1]+[Mark2]))
Now I need to drop formula nature of this column total and assign default value '0'. I like to know how to do it using T-Sql script.
Thanks for your help in advance.
Hi guys,
If I have a temporary table called #CTE
With the columns
[Account]
[Name]
[RowID Table Level]
[RowID Data Level]
and I need to change the column type for the columns:
[RowID Table Level]
[RowID Data Level]
to integer, and set the column [RowID Table Level] as Identity (index) starting from 1, incrementing 1 each time.
What will be the right syntax using SQL SERVER 2000?
I am trying to solve the question in the link below:

Thanks in advance,
Aldo.
I have tried the code below, but getting syntax error...
ALTER TABLE #CTE
ALTER COLUMN
[RowID Table Level] INT IDENTITY(1,1),
[RowID Data Level] INT;
I have also tried:
ALTER TABLE #CTE
MODIFY
[RowID Table Level] INT IDENTITY(1,1),
[RowID Data Level] INT;
My CTE is failing and I don't know why...Is there a Common Table Expression column name length restriction???
View 2 Replies View RelatedI 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?

Hi,
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! =)
I have a column (PERIMAGE_PATH) in my table. The data in this column is imported from a fixed width text file and looks like the following:
07J06274
05J03254
04J11245
I need to modify the data in the column to look like this:
..images 7J06274.jpg
..images 5J03254.jpg
..images 4J11245.jpg
How can I do this?
Thanks for all your guys' help. This is the last question for the day. I promise

Hello,
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

Hi,
I am creating a piece of code to create audit tables based on my current tables. I'm using the info in sysobjects to get this done, but I have one problem.
I can't seem to find the actual lenght of a column, I tried with the systypes.length, but that was obviously not what I needed. Does someone know how (or where) I can retrieve the length that I need?
thx in advance.
I have a table this is populated by a flat file. In the desc field from the flat file some of the data is very long up to 150 characters in length. I have to export this data after some transformations to a fixed width file. I need to check the length of the data in the desc field and any thing that is to long needs to be put in a desc2 field, however any values in desc that are shorter than 36 characters in length needs to have spaces padding it up to 36 characters as well as the desc2 field. Any help would be great. I am not the best T-SQL programmer in the world and have limited time to get this done.

Friends,
I was trying to find out the maximum length of a row in a column.I was using SQL65.I will appreciate if any one can give me the query to find this.
Thanks in advance
Can you alter a column and make it longer without dropping the column

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 -

I have some text in an NText column that could be quite long.
for the web page that displays it, i want to show the first 200 characters and then have a "more..." link to bring up the full text.
i'd like to create a stored procedure that takes the left 200 characters and copies them to a ShortText column (NVarChar) for initial display and then id like to set a bit column to indicate if the length of the NText column is greater than 200.
Len and Left cant be used against NText so how can i work with the NText data ??
Hello, I am using the JDCB-ODBC driver for my app, but one of the columns in my WHERE clause is 255 characters long. Because of this no rows are returned even though the statement should return 1 or 2 rows. I've tried other JDBC-ODBC drivers too and they have the same problem. Additionally, I've tried using RTrim(), Substring(), etc and it still will not work....any ideas? Is it a driver bug? Anyone know of a driver that will work?
Sample code....
ResultSet rs = dbRetrieve.getStatement().executeQuery( sql ) ;
if (rs.next()) {
// Never gets here
}
Thanx!

Hello,
I have an ODBC connection manager to a Progress database. In that database there is a column declared as a string of 10 characters long.
However, some data in this column is actually up to 15 characters long.
This makes my DataReader Source fail everytime I try to run my package because it sets the output column like this :
Datatype : Unicode string [DT_WSTR]
Length : 10
Is there any way to solve this without changing the datatype in the Progress database (that is beyond my control) ?
tanks in advance ...
According to the MSDN, in SQL Server 2000

I have a table with 500 columns, most of them are type of varchar. I would have the following data set:
ColumnName DataTypeLength MaxLength
-------------------- -------------------- -------------------
ColA 50 42
ColB 10 7
ColC 50 8
.... ... ...
I can have a query to get the data type length (hom many varchar) for each columns:
SELECT column_name, data_Type, character_maximum_length
FROM information_Schema.columns
WHERE table_name='***'
ORDER BY ordinal_position
but I have problem to get the actual maximum length of the each column. Anybody have the similar query?
thanks,
