What causes SQL Server 2000 to create tables with default column sizes of 8000 for a varchar datatype??
I would assume this can cause significant performance problems.
(see attached)
Hello, everyone:
I want to add a column, INT NOT NULL DEFAULT 0, to a table. There are about 9 mil. records, 57 columns in the table. SQL 2k on Win 2003. What impact maybe bring?
1) Is there a down time on database and server?
2) Is it possible to insert records during adding new column?
3) How long will be taken roughly?
Thanks a lot.

Hi,
I wrote this sql function which takes a comma seperated string of numbers, splits the numbers seperately and stores it in a table. I have specified the input parameter type as text instead of varchar, the size of the string can get more than 8000.
But the function is not working properly if the input size is more than 8000. For example if the input string is of length 8005 and this is the input string from 7995 to 8005 - '123,124,125'. It works fine till 123 and after that it throws an error, Syntax error converting the varchar value '124,125' to a column of data type int. Can anyone tell me what is wrong with this. I am using string functions like charindex, substring. I can post the full function if you want.
Thanks.
Hello All,
When creating my database I have modeled some of the tables after the Adventureworks sample database.
There are some fields or entire tables in Adventureworks that I do not see an imediate use for, however; I would hate to ommit them to find out later they would have been benificial. (.eg territory table).
In general terms what would the impact be on size and performance of a database which contains tables or fields that do not contain data.
Thanks for your help!
Hi..
I m working on MS SQL Server 2000.
I am trying to pass a list of numbers to a stored procedure to be used with 'IN()' statement.
I was doing something like..
Create Procedure proc
(
@Items varchar(100) --- List of numbers
)
AS Begin
Declare @SQL varchar(8000)
Set @SQL =
'
Select Query......
Where products IN (' + @items + ') '
'
Exec (@SQL)
This stored procedure is working fine, but when i m adding more required stuff to that, the size exceeds 8000, & it gives the error "Invalid operator for data type. Operator equals add, type equals text."
Can any1 please help me out with this ASAP??
when creating a new table. How can I set the default value of the column to equal the value of another column in the same table?
View 5 Replies View RelatedI notice when I create a new database within my SQL Server that the
permissions for the new database automatically adds a user (Who is configured
as sysadmin) with dbo permissions to this database.
Both within the login properties of the select user (User mapping) is listed
as Default Schema, dbo and within the permissions of the database listed as
user with connect permissions.
I have other users configured as sysadmin and they do not get this rights
(They are not expliticly listed within user mapping with dbo or permissions
as user within the database).
I've inherited this system and wonder if the user has somehow changed the
new database procedure so it changes the default permissions of new databases.
Any way to check what he's done, I can see no differences between him and
the other sysadmins but he's definatly specifically listed as a dbo on all
new databases.
Although I don't mind him having access, he's a sysadmin after all, I'd like
to make it uniform thoughout the system, i.e. using the inhertited
permissions rather than specific permissions that seem to be created when the
new database is created.
Any ideas?

Is there any possibility to store more then 8000 chars in a column?
View 1 Replies View RelatedHello all,
I have a table with a column:
ThruDate datetime not null
I have a function call set up as default for the col
([dbo].[fn_DateHigh_Get1]())
I have a stored procedure that inserts into the table - it expects @ThruDate as a parm. I default the parm to NULL -
When the sp executes its insert stmt i get error 515 (null cannot be inserted....).
When i just enter the row manually in enterprise manger (and just tab through the ThruDate col) all is well - ThruDate gets the default as calculated by function [dbo].[fn_DateHigh_Get1]()
Why does the sp fail - i.e. why isn't the default applied?
thanks
I have installed my modell database onto c:mssql7data...
How do I now change the properties of this so that when someone creates a database, the path it will get created to is set to d:
I thought that I could just move model, but it seems that this isn't possible.
Any advice?
thanks

How to set a default value to columns in table ..without dropping it.??

I need to change the size of a column of a table from char(255) to char(500). I used the line:
alter table table_name alter column column_name char(500)
When I run that command, I get a message that it was sucessful. However, when I try to enter data into the changed column, the number of characters I can enter is still 255. I check the information schema for the column and the 'character_maximum_length' field is 500.
What is the problem here? Is the maximum allowable length for char 255? How can I get a column to have 500 characters?
Is there any way to get size of the individual column in a table?
I know we can use sp_spaceused to get the size of the table. But my question is diiferent. I have a table with 50 columns and approx 2 million rows in it. I wanted to know which column is taking most of the space.
Thanks
I want to be able to have an authorized person set or change the default values of a table column in a SQL Database. I have a stored procedure that sets the default which works fine: ALTER PROCEDURE [dbo].[addMyConst]ASBEGINALTER TABLE [dbo].[tbl1]ADD DEFAULT 70 FOR [Auto_ourlim]END(I still need to put parameters in so that I can run the stored procedure from a form, but for now....)
To change it I know that I have to drop the constraint first like this:
ALTER PROCEDURE [dbo].[dropmyValue]ASALTER TABLE [dbo].[tbl1] DROP CONSTRAINT [Auto_ourlim]
The problem is that when I execute the procedure I get the error that "Auto_ourlim" is not a constraint so it does not drop the Default Value. When I go over to SQL Server Management Studio Express I can see why:
If I open up the table and open up the Constraints the constraint is "DF__tbl1__Auto_ourli__5FB337D6". I could change the DROP CONSTRAINT to this, and that works, but it changes every time I add the new DEFAULT VALUE. I don't know how to get around it. Is there a way to put wildcards around "Auto_our" in DROP CONSTRAINT [Auto_ourlim}? Any suggestions would be welcome...even if there's a totally different way to do it.
What I'm trying to ultimately accomplish is this: Column1 (AutoLimits) would be user insert to the database and then in the database it would MINUS Column2 (Auto_ourlim - set with the default value) = Column3 (Difference - a computed field in the database)

Does null column take storage in table ? I created the following table:
drop table [dbo].[TBL_orig]
CREATE TABLE [dbo].[TBL_orig](
[1] [bigint] NOT NULL,
[2] [bigint] NULL,
[3] [bigint] NULL,
[4] [bigint] NULL,
[5] [float] NULL,
[Code] ....
Does null value will take a place even no data insert to this columns and if yes this answer is 4 mb is logical gap ?
Hi All,
I want to know what will be the impact of changing the primarykey on a table which already has a lot of data.
For example, column A is unique, primary key. I want to make column B as unique, primary key.
Can I do that? What will be the impact on database performance?
Thanks

I am able to get reports going with tables sized properly. They look fine on the ReportServer website and I adjust the column widths so that the headings and data look nice. When I set up a subscription to be delivered by "Report Server E-Mail," though, the table formattings get completely distorted.
In particular, I have two tables, with some column headers being two short words (e.g. Max Height). When rendering on the site, I adjust the columns so the full column header is visible on one line. When I receive the email and read it in Outlook, the header row is now about twice as tall and everything is scrunched together. Both the headings and the data in the fields do not format the same as on the website.
The two tables tend to actually have the exact same width in the email version, although occasionally they are a little different (in the web version one is about half as wide as the other). I have tried just making the columns bigger and that has not worked. I've tried making the font sizes smaller, which didn't work. If I do that, leaving the columns the same width, the email version just gets scrunched into a smaller area with the same text-wrapping problems.
If I open the email in a browser (in a web mail interface) the report renders perfectly as on the site.
I have almost all the default settings, and haven't been messing around with page sizes and things like this (except after, to see if that would fix the problem).
Any ideas, similar experiences, or suggestions? If there is a book I should read or any reference you could point me to in order to figure this out would be helpful. I haven't been able to understand this either using web searches or the two SQL reporting services books I have.
Just a quick easy question. If I alter a table (add a column to the table), will it take the table offline during the ALTER process? I am adding the column to the end of the table not in the middle. I know if I add it in the middle it will offline the table.

It just takes a LOT of time in SQL Server Management studio. I have to cancel the query and cancelling takes a whole lot time. I am using SQL Server 2008.
SQL Server 2000:
Question 1
If you drop / rename a table and then recreate the table with the SAME NAME, what impact does it have on stored procedures that use these tables? From a system perspective, do you have to rebuild / recompile ALL the stored procedures that use this table?
I had a discussion with someone that said that this is a good idea, since the IDs of the tables change in sysobjects and from a SQL SERVER query plan perspective, this needs to be done...
Question 2
If you Truncate a Table as part of a BEGIN TRANSACTION, what happens if an error occurs? Will it Rollback? The theory is that it won't because Truncate doesn't utilize the logs where as Delete From uses the SQL Logs?
Thanks!
What is the impact on the users to drop an index on a table while in use? I will recreate the index afterwards. The table is used constantly by a three of processes/users at all times.

View 4 Replies View RelatedDoes anyone know of a way to execute sql code from a dynamically builttext field?Before beginning, let me state that I know this db architecture isbuilt solely for frustration and I hope to make it better soon.Unfortunately, there is never a non-crucial time in which we can do anupgrade, so we are stuck for now.Point 1:There are multiple tables: students, courses, cross-referencestudent/courses, teachers, cross-reference teacher/courses, andothers.Point 2:Yearly archiving is done by appending a 2 digit year suffix to thetable and rebuilding the table structure for the current year. Thatis, each of the tables named above has an archive table for 1999,2000, 2001, etc. This leads to many tables and a big mess whenunioning them.Point 3:A history report is run by building a big query that unions each unionof tables (students, courses, etc) by year. This query has grown toobig for a varchar(8000) field. Actually, it's too big for 2 of them.Point 4:I don't want to write code to maintain any more varchar(8000) fieldsfor this query. It should be much more easily handled with atemporary table holding each bit of yearly archive data. I have builtthis and it works fine. I have also figured out how to pull the rowsfrom that table, concatenate them, and insert the resulting lump intoa text field in another table.Point 5:I haven't figured out how to grab the 5 or so records from that tableand execute them on their own. I figured I could grab them, put theminto a text field that's big enough to hold the whole query and thenselect and execute that text field. I've had no luck with that and Ihaven't had any luck finding any references that might help me withthis problem. I keep thinking of nesting execute() calls, but thatdoesn't work.I'm open to questions, potential solutions, hints about different wayto approach the problem, anything.Many thanks in advance,Rick Caborn

I have been trying to configure the Paper Size to be default "A4" instead of "Letter".
My Report is configured to 21cm x 29,7cm and margins 1,5cm.
The Body is configured to 18cm x 26,7cm.
Everything looks fine in the Preview but the Size is always "Letter". The printers are all configured for A4 printing.
Is there a way to set these default values in the Page Setup Toolbar or is it supposed to figure it out?
Thanks,
