But one thing i'm still not clear on is about altering relationships between
tables after they've been created.
Instead of creating a foreign key when the table is first created - i create
the table and then run a query to set the foreign key and relationship
(one-to-one, one-to-many etc)
Anyways, long story short is i want to create a one-to-one relationship with
a table but am having problems with adding more than one constraint at a
time when altering a table.
Understand yet? Easiest thing to do is show you:
I have 2 tables: Branch_Table and Employee_Table
I want to create a one-to-one relationship between emp_id on the
Branch_Table and manager_id on the Employee_Table.
The SQL i've written which doesn't seem to work is:
I finally found a way to "deploy" my local SqlServerExpress (SSE) database to the remote Sql2K server... In VisualWebDeveloper (VWD) I can create the table definition and then save the creation sql script and use that in SSE Express Manager while connected to my remote DB. I am describing this because I'm so surprised no one has had problems with this as thousands of developers, some very unexperienced (as me maybe!), are trying the same situation now that some are offering 2.0 hosting... Well I thought this was a great idea until the Sql2K server is returning error messages on the script VWD created. So please could you help since I'm not that good at complex sql scripting. It seems the error comes from the ALTER TABLE syntax:BEGIN TRANSACTIONSET QUOTED_IDENTIFIER ONSET ARITHABORT ONSET NUMERIC_ROUNDABORT OFFSET CONCAT_NULL_YIELDS_NULL ONSET ANSI_NULLS ONSET ANSI_PADDING ONSET ANSI_WARNINGS ONCOMMITBEGIN TRANSACTIONCREATE TABLE dbo.Table2 ( prID int NOT NULL IDENTITY (1, 1), DateInserted datetime NOT NULL, Title nvarchar(100) NOT NULL, Description nvarchar(MAX) NULL, CategoryID smallint NOT NULL, DateLastUpdated datetime NULL, Price int NOT NULL, SpecialPrice int NULL, ImgSuffix nvarchar(5) NULL, ImgCustomWidth smallint NULL ) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]GOALTER TABLE dbo.Table2 ADD CONSTRAINT PK_Table2 PRIMARY KEY CLUSTERED ( prID ) WITH( STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] GOCOMMIT

I have about 100 databases which yeterday had the wrong ddl for a column added, we have a simple cursor that loops through all databases on the server and runs the sql statement.
The following was run
ALTER TABLE salesrep ADD newCol bit DEFAULT 1
Problem is that it should have been this (and preferably have had a named constraint):
ALTER TABLE salesrep ADD newCol bit NOT NULL DEFAULT 0
Problem is now i dont know the names of the contraints they have random hex on the end "The object 'DF__SALESREP__newCol__5BCD9859' is dependent on column..."
How do i just drop this column with ANY constraints on it?,
I really dont want to go through the databases 1 by 1 and look up the constraint name then drop the constraint, then drop the column so i can add it in correctly.
I wish the following would just work.
ALTER TABLE salesrep ALTER COLUMN newCol bit NOT NULL Default 0
ALTER TABLE [dbo].[CalCalendar] ALTER COLUMN [OID] uniqueidentifier NOT NULL PRIMARY KEY NONCLUSTERED
is answered with:
Server: Msg 156, Level 15, State 1, Line 2 Incorrect syntax near the keyword 'PRIMARY'.
which I consider to be interesting. Anyone has an idea why? I checked documentation but I do not see an error.
Note that:
ALTER TABLE [dbo].[CalCalendar] ALTER COLUMN [OID] uniqueidentifier NOT NULL
DOES get executed, and
ALTER TABLE [dbo].[CalCalendar] ALTER COLUMN [OID] uniqueidentifier NOT NULL PRIMARY KEY
produces the same error.
Now, in my understanding this has nothing to do with an index may already exist etc. - the eror indicates a SYNTAX error, before any checking. Makes no sense to me, though, reading the documentation.

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: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2093921&SiteID=1
Thanks in advance, Aldo.
I have tried the code below, but getting syntax error...

I have also tried:
ALTER TABLE #CTE MODIFY [RowID Table Level] INT IDENTITY(1,1), [RowID Data Level] INT;
I know this is probably a flick of a switch but I cannot figure out which switch. Setup is SQL Server / Stored Procedures / DAL / BLL(skipped for testing) / PL. The stored procedure queries from only one table and two columns are ignored because they are being phased out. I can run the stored procedure and preview the data in the DAL but when I create a page with an ODS linked to the DAL and a GridView I get this error. I checked every column that does not allow nulls and they all have values. I checked unique columns (ID is the only unique and is Identity=Yes in the table definition). I checked foreign-key columns for values that are not in the foreign table and there are none. Any ideas why do I get this? Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.
Hi, I am getting the above error when trying to load a report into my Web Application, I have tracked the error down to one specific field in my database. Even though this field is a NVarChar field and is of size 30 it would seem that there is an issue returning the value from the field. I can write it into the database no problems but when I try to get it out of the database it returns the above error. e.g MOB 401.908.804 - Fails 0401.907.324 - okay 8239 9082 (pager) - fails Anyone got an idea on how to fix this???? Regards.. Peter.
I ran this query against the pubs database and it runs successfully
ALTER TABLE publishers ALTER COLUMN state CHAR(25)
I change the table & field names for my db as follows: ALTER TABLE customquery ALTER COLUMN toclause CHAR(25)
and run against my database and I get the following error - Incorrect syntax near 'COLUMN'.
My column name is correct - I don't know why it would run fine against pubs, but not my db. I do not have quoted identifiers turned on. I have tried using [] around my column name [toclause], but that didn't change anything. Any help would be appreciated. Thanks.
Can anyone recommend a good article/book on the subject? I am trying to find out more about compound primary keys. How many is “too many”? Does the number of primary key columns affect your performance? If so, how does it affect it? Should some of the constraints be handled from stored procedures?
I am new to MsSql. I want to know is there any command through which we can get all the consraints on a table or in a databases. In the same way how to get the all table names in a database from the coomand prompt or thorugh query analyzer.
we have a table in our ERP database and we copy data from this table into another "stage"Â table on a nightly basis. is there a way to dynamically alter the schema of the stage table when the source table's structure is changed? in other words, if a new column is added to the source table, i would like to add the column to the stage table during the nightly refresh.
This is an SQL Server 2000 question. Without having access to the "Design Table" option in the pop-up menu of a table, is there another way to see what constraints, indexes, primary key, etc. that a table has?
I have contract table which has built in foreign key constrains. How can I alter this table for delete/ update cascade without recreating the table so whenever studentId/ contactId is modified, the change is effected to the contract table.
Thanks
************************************************** ****** Contract table DDL is
create table contract( contractNum int identity(1,1) primary key, contractDate smalldatetime not null, tuition money not null, studentId char(4) not null foreign key references student (studentId), contactId int not null foreign key references contact (contactId) );
For the length of Column ID is not enough, So I want to alter its length.The alter statement is:
ALTER TABLE student ALTER COLUMN ID CHAR(20)
For the table student is referenced by table score, the alter statement can not alter the column of the table student, and the SQL Server DBMS give the errors.
But, I can manually alter the length of the column ID in SQL SERVER Management Studio. How to alter column length of the master table(student) along with the slave table(score)?
I remember once using a command in Query Analyser that gave me all theinformation about a table. It showed details about the columns,constraints, keys, indexes etc.I can't remember how I did this? Can anyone help me?It could of been a stored proc that I called or a query on the systemtables.I do know that it was very simple to do and it was executed in QueryAnalyser.Can anyone help me?

A customer wants to implement table partitioning on a replicated table.
They want to hold 13 months of data in the table and roll off the earliest/oldest month to an identical archive table. The table has a date field and partitioning by month makes sense all around.
So SWITCH PARTITION is the obvious solution to this, except for the fact that the table is replicated (transactional w/no subscriber updates).
What are his architectural or practical solutions to using table partitioning and replication?
I need to script out data in several tables (30+) and then reload those tables on a different database. Â The "target" database table data will get overwritten each time, not appended to. Â Several of these tables have numerous foreign keys and other constraints that must be dealt with. Â None of them have more than 100 records or so. Â Then I need to keep this script in source control and reference it as part of a post-deployment step with a Visual Studio DB project.
I have redgate, dbghost and visual studio. Â Are there any tools will generate the script for me complete with dropping all the constraints, truncating the tables, then re-adding the constraints back? Â Or, am I looking at simply scripting the table data out, then modifying the script myself to add in the steps to drop/readd the constraints? Â Further, since some of these tables might have relationships, not just to other tables, but to those in question, there will likely be an order in which the tables need to get loaded.
The approach I am thinking will be needed, since ive done this sort of thing before except with SSIS, is to run something like dbghost or the "generate scripts" option in SSMS as a starting point. Â From there, change the order around as needed, etc. Â
