Doing the exercises in a book, which starts CREATE DATABASE xyz ON PRIMARY...
It fails, so stepping through it. What is PRIMARY?
Searching Help seems always to give primary KEY, but cannot be that at point of creating the DB.

l would like to run a health check on my newly designed database to ensure that l've covered all the necessary points to ensure that l have a good database. Is there there such a procedure?
If l want to create a primary key on a table with duplicates, how would l achive that? l tried to create a new table then create the pk. then ran the following script to populate
instert into tabB
select * distinct tabA
It did not work. Please advive
I am using SQL express and Visual web developer on windows Vista.
When I try to create a new database the following message appears.

I think there has to be a way to do this but I'm not seeing it.
I would like to set the names of my primary keys in the CREATE TABLE statements. I like this for documentation so it's very clear what the PK name is. When the system generates the key names, it always add the number suffix at the end. I would need to do this both when the PK is a single column and when it is multiple columsn (see examples below).
Thanks very much for your assistance.
CREATE TABLE dbo.SecAppRole1 (
app_id INT IDENTITY(1,1),
app_name_field VARCHAR(128) NOT NULL PRIMARY KEY ,
app_role VARCHAR(128) NOT NULL,
app_role_password VARCHAR(50) NOT NULL)
CREATE TABLE dbo.SecUserAppPermission1 (
app_id INT NOT NULL,
windows_user_name VARCHAR(128) NOT NULL,
user_permission CHAR(01) NOT NULL,
PRIMARY KEY CLUSTERED (app_id ASC, windows_user_name ASC))
With the last table being created below, it has a clustered primary key.One of the fields it is referencing on the previous table, courseId, can NOT be unique.But without it being unique, the cluster primary key won't work.Is there another way to achieve what I am trying to do here?CREATE TABLE dbo.courseScores ( courseId varchar(20) NOT NULL CONSTRAINT FK_courseId_courseStructure2 FOREIGN KEY (courseId) REFERENCES courseStructure (courseId),
studentId varchar(20) NOT NULL CONSTRAINT FK_studentId_students2 FOREIGN KEY (studentId) REFERENCES students (studentId),
CONSTRAINT PK_courseScore PRIMARY KEY CLUSTERED (courseId, studentId)
)
CREATE TABLE dbo.objScores ( objID varchar(20) NOT NULL CONSTRAINT FK_objId_objstructure FOREIGN KEY (objID) REFERENCES objStructure (objID),
studentId varchar(20) NOT NULL CONSTRAINT FK_studentId_students3 FOREIGN KEY (studentId) REFERENCES students (studentId),
courseId varchar(20) NOT NULL CONSTRAINT FK_course FOREIGN KEY (courseId) REFERENCES courseScores (courseId), CONSTRAINT PK_objScores PRIMARY KEY CLUSTERED (objID, studentId, courseId) )
Thanks all,Zath
I have an access table that has a primary key (entitled "ID Number"), no duplicates, the field is an integer.And, importantly, the value is set to "increment".The format is "phd"000 - so it starts out phd001, phd002, and so on...How to do this in an SQL table? Can that format be done? Or is it better not to do it via SQL but in coding instead?

for MS SQL 2000
how can I do this in one time (into the CREATE TABLE)
CREATE TABLE [dbo].[Users] (
[id_Users] [int] NOT NULL ,
[Name] [nvarchar] (100) NULL,
[Serial] [nvarchar] (100) NULL,
) ON [PRIMARY]
ALTER TABLE [dbo].[Users] WITH NOCHECK ADD
CONSTRAINT [PK_Users] PRIMARY KEY CLUSTERED
(
[id_Users]
) ON [PRIMARY]
CREATE UNIQUE INDEX [IX_Users] ON [Users]([Serial]) ON [PRIMARY]
and that one
CREATE TABLE [dbo].[UsersExtra] (
[id_Users] [int] NOT NULL
) ON [PRIMARY]
ALTER TABLE [dbo].[UsersExtra] ADD
CONSTRAINT [FK_UsersExtra_Users] FOREIGN KEY
(
[id_Users]
) REFERENCES [Users] (
[id_Users]
) ON DELETE CASCADE
thank you
Hi, I'm in the midst of an Access 2003 to SQL server 2000 upsizing project and have come across a table on Sql Server that has a field that looks like it's supposed to be the PK but it contains duplicates. What I'd like to do is to have a cursor start at the first value and increment the next value by 1. Could someone explain how I'd go about this?
Many thanks,
Peter
I am trying to create a FK using a composite PK and here are the details that I want to achieve.
Table -A
Column A1 not null,
Column A2 not null
Primary key (A1, A2).
Table -B
Column B1 Primary key.
Column B2 not null
FK (B2) References A(A1).
When I try to do this I am getting some errors. Questions: First of all is this possible? if yes, then how I can create it.
In what situations we can create primary key on a table? I mean what is the minimum no of rows we can prefer to create PK.

Jon Galloway provided a sample in http://weblogs.asp.net/jgalloway/archive/2008/01.aspx but the Primary Key Field and Primary Key Value were inserted into separate columns while I need to combine the Primary Key Field and Primary Key Value into 1 single field, using his example, I want to form the primary key as:
ScoreId = 423
ScoreId = 3064
etc.
Note that his example only show a single primary key in a table whereas I need to handle multiple primary keys in a table.
I have two practice tables I have created and want to export the values of one into the source table. I want to know if I can export into a table and have the destination table automatically give a primary key value to a record? I haven't been able to figure this out even after fiddling with the "Enable identity insert" checkbox under the Column Mappings tab. I have created source tables with and without primary keys and neither works because of the fact that I need to have a value for a primary key in order to INSERT into the destination.
Do I have to copy the source records into a staging table and assign the PK values myself by hand? This can't be the answer.

This is for SQL2k5. The database may be small or big, I don't know (it's going out to multiple customers). I'm wondering if in general it's considered "better" to create a single non-primary default filegroup and put all the objects there, or just leave everything in primary? In one training years back I got the impression that recovering the primary filegroup was important for certain restore operations, so it was always wise to separate them like this.
Thanks for your input,

I'm trying to get a SQL 7 and 6.5 DB to interact, but while there is no problem in SQL7, I cannot create a table called "Public" or a field called "Primary"!!
Does anyone know why this might be and if so where I might get a list of any other "invalid" names??
Thanks in advance,

Hi All
I hope someone smart can help me, it would be highly appriciated.
I am developing an SQL Serverdatabase and in on of the tables I need the primary key to consist of two pieces of data.
TblOrders: OrderNum, Orderdate, ....
TblDispatchers: DispatcerID, Dispatcher, DispatcherAddress
The OrderNum field in TblOrders need to be a composite of an AutoNum-field (incrementet by 1) and the DispatcerID from the tblDispatchers.
Can this be done, and how.
Many thanks
Kind regards

I have a table with plant types and plant names. Certain plants are grouped on a custom field, currently called Field. I am trying to create a query that will give me a result set containing the primary order on Type, but need items with the same 'Field' value grouped by each other.For example, the following shows a standard query result with "order by Type", ie select * from plants order by Type
Code:
ID Type Name Field
1 Type1Name1(group1)
2 Type2Name2(group2) -group2
3 Type3Name3(group3)
4 Type4Name4(group4)
5 Type5Name5(group2) -group2
6 Type6Name6(group6)
But I want it to look like this, with fields of the same value located next to each other in the result set (but still initially ordered by Type)
Code:
1 Type1Name1(group1)
2 Type2Name2(group2) -group2
5 Type5Name5(group2) -group2
3 Type3Name3(group3)
4 Type4Name4(group4)
6 Type6Name6(group6)
For a new project. I need to create random alphanumeric characters as primary key values when inserting a record.

I don't want to use guid or auto increment integer or sequence.

Hi all,
I downloaded and ran AdventureWorks.msi into my SQL Server Management Studio Express (SSMSE) one year ago.But I did not know how to attach it to my SSMSE then. Last week, I deleted it from the "Add or Remove" of Control Panel and I downloaded the new AdventureWork.msi and installed it my SSMSE. Today, I tried to use the Database Explorer of VB 2005 Express for the first Stored Procedure programming. I clicked on AdventureWorks.mdf and I got the following error: One or more files do not match the primary of the database. If you are attempting to attach a database, retry the operation with the correct files. If this is an existing database, the file may be corrupt and should be restored from a backup. Cannot open user default database. Login failed. Login failed for user 'CENADe1enxshc'. Log file 'C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataAdventureWorks_Data_log.ldf' does not match the primary file. It may be from a different database of the log may have been rebuilt previously. Please help and advise me how to correct this problem.

Hi all,
I use the following 3 sets of sql code in SQL Server Management Studio Express (SSMSE) to import the csv data/files to 3 dbo.Tables via CREATE TABLE & BUKL INSERT operations:

)
GO
========================================
The 3 csv files were successfully imported into the ChemDatabase of my SSMSE.
2 questions to ask:
(1) How can I designate the Primary and Foreign Keys to these 3 dbo Tables?
Should I do this "designate" thing after the 3 dbo Tables are done or during the "Importing" period?
(2) How can I set up the relationships among these 3 dbo Tables?
Please help and advise.

the subject pretty much says it all, I want to be able to do the following in in VB.net code):

How would I do this?
Hi, I have a Users table that I use for membership. Now I am using username varchar(30) as the primary key for this table since username will always be unique.I am storing username in UsersInRole table so that I can find what roles each user has.The question I have is regarding how SQL Server actually stores data:I see that when I add users, they are always stored alphabetically sorted on username. I was expecting that all users will appear on the users table in the order they were added.Example: I have 3 users (john, jonah, wilson). Now I added 4 user with username='bob'If I execute select * from users, it returns me (bob, john, jonah, wilson). Look bob is has become the first row of the table.My question: Is Sql server moving 3 older rows to make room for 'bob' and it is also rebuilding part of the index due this new username 'bob'?If this is the case, then it will have big impact if I have 100K users and I add one user that becomes firstrow. In that case huge other rows will have to move.Bottom line, insert, delete will be expensive. I know sql server keeps data physically sorted on PK. But I am concerned here since rows are losing the order in which they were inserted.Thanks

I'm new to using SSIS and have been reading and learning slowly how to use it. I'm trying to create an identical copy of our database for reporting. I've used the Import/Export wizard, but have had some issues with foreign keys and with sql_variant columns.
I've tried searching for anything but haven't had any luck as of yet. I guess I don't even know where to start or what to look for.
Any help would be appreciated. Thanks!
I desire to have a clustered index on a column other than the Primary Key. I have a few junction tables that I may want to alter, create table, or ...
