I have these two identical tables with the columns CODE & Qtr being COMPOSITE PRIMARY KEYS

Can anybody help me with how to compare the two tables to find the records not present in Table 2

That is i need this result







    Code
   Quarter

500002
28

500002

scrip_cd+Qtr not in (select scrip_cd+qtr as 'con' from Table2)

i need to know if there is some other way of doing the same

Composite Primary Keys Versus Composite Unique Indexes

Feb 20, 2007

Hello,

I have a table which has a composite primary key consisting of four columns, one of them being a datetime called Day.

The nice thing afaik with this composite key is that it prevents duplicate entries in the table for any given day. But the problem is probably two-fold

1. multiple columns need to be used for joins and I think this might degrade performance?
2. in client applications such as asp.net these primary keys must be sent in the query string and the query string becomes long and a little bit unmanagable.

A possible solutions I'm thinking of is dropping the existing primary key and creating a new identity column and a composite unique index on the columns from the existing composite key.

I would like to have some tips, recommendations and alternatives for what I should do in this case.

Composite Primary Keys

Jun 25, 2002

Newbie question...

I have two tables (categories & listings) which create a many-to-many relationship.

I have created an interim table with the primary keys from each table as a composite primary key...(cat_id & list_id).

How does the interim table get populated with the id's?

When I do an insert statement to insert data into the categories table, the cat_id field is automatically generated...same with the listings table, but when (and how) does the primary key data get into the interim table.

Thanks in advance for the assistance.

Inserted Records Missing In Sql Table Yet Tables' Primary Key Field Has Been Incremented.

Jun 18, 2007

I have a sql sever 2005 express table with an automatically incremented primary key field. I use a Detailsview to insert new records and on the Detailsview itemInserted event, i send out automated notification emails.
I then received two automated emails(indicating two records have been inserted) but looking at the database, the records are not there. Whats confusing me is that even the tables primary key field had been incremented by two, an indication that indeed the two records should actually be in table.  Recovering these records is not abig deal because i can re-enter them but iam wondering what the possible cause is. How come the id field was even incremented and the records are not there yet iam 100% sure no one deleted them. Its only me who can delete a record.
And then how come i insert new records now and they are all there in the database but now with two id numbers for those missing records skipped. Its not crucial data but for my learning, i feel i deserve understanding why it happened because next time, it might be costly.

Comparing Data In Two Tables To Find Missing Records

Jul 20, 2005

I have two tables of book information. One that has descriptions of thebook in it, and the isbn, and the other that has the book title,inventory data, prices, the isbn.Because of some techncal constraints I won't get into now, I can'tcombine them both into one table. No problem. Things are going fine aslong as there is a description in the one table to corrispond to theisbn and other data in the other table.However, about half of the products are not yet entered into thedescrition table. I'd like to run a sql query that pulls up all theisbns that don't exist in the other. In other words, I'd like to get aquery that tells me exactly which isbns do not yet have descrition datain them. I know there is some sql that says to search from one filewhere the number does not exist in the other, but it slips my mind. Cansomeone help me on this please?Thank you!Bill*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!

Audit Tables With Composite Keys

Aug 31, 2007

I am trying to write triggers on each tables in my database to audit data changes. My AuditLog table consists of the following columns -

LoginName varchar(100) - user name
Action varchar(5) - this will store 'INSERT','UPDATE','DELETE'
TableName varchar(30) - name of the table updated
PrimaryKey int - primary key of the record updated
ColumnName varchar(30) - name of the column updated
OldValue varchar(1000) - old value converted to varchar
NewValue varchar(1000) - new value converted to varchar
RecUpdDate datetime - record update date.

This table design will work for tables with single column primary keys. However, it will not work for tables with composite primary keys. Any suggestions on how to make this work with composite primary keys? I prefer not to change the tables in my database to use single column primary key.

Thanks in advance.

Creating Indexes On Columns That Are Foreign Keys To Primary Keys Of Other Tables

Jul 16, 2014

what the best practice is for creating indexes on columns that are foreign keys to the primary keys of other tables. For example:

[Schools] [Students]
---------------- -----------------
| SchoolId PK|<-. | StudentId PK|
| SchoolName | '--| SchoolId |
---------------- | StudentName |
-----------------

The foreign key above is as:

ALTER TABLE [Students] WITH CHECK ADD CONSTRAINT [FK_Students_Schools]
FOREIGN KEY([SchoolId]) REFERENCES [Schools] ([SchoolId])

What kind of index would ensure best performance for INSERTs/UPDATEs, so that SQL Server can most efficiently check the FK constraints? Would it be simply:

CREATE INDEX IX_Students_SchlId ON Students (SchoolId)
Or
CREATE INDEX IX_Students_SchlId ON Students (SchoolId, StudentId)

In other words, what's best practice for adding an index which best supports a Foreign Key constraint?

Missing Identity Values In Primary Keys

May 29, 2012

We are facing the following issue, several machines/users that are executing very often a command similar to :

INSERT INTO TableName (FieldOne,FieldTwo) VALUES ('ValueOne','ValueTwo');
SELECT SCOPE_IDENTITY() AS Table_ID;

Where TableName has a primary key defined as identity(1,1).and that Table_ID is being used as reference in others tables

These queries are executed using different dababase users and among several diffrent apps..The Problem is that we are detecting lost block of "Table_ID's" as the other tables shows the InsertedID as a reference, but the TableName table lacks of this ID record. In other words, the INSERT seems to work, the SCOPE_Identity returns an InsertedID, and the other tables are populated using this number. However, when we query the TableName table the mentioned record does not exist. We are profiling the server and we're sure that there are no DELETE statement on the TableName table. This seems to be happening when the are either deadlocks or blocked processes. Whenever the deadlocks and locks disappear/solved, everything works as expected.why the Scope_Identity returns the Inserted ID if the INSERT action had failed.

How Do I Create A Composite Primary Key, Using Fields From Multiple Tables?

May 22, 2007

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

Trying To Find Non Identity Primary Keys

Jan 26, 2006

This ain't working

This is giving me bogus results...

SELECT * FROM INFORMATION_SCHEMA.COLUMNS
WHERE OBJECTPROPERTY(OBJECT_ID(COLUMN_NAME),'IsPrimaryKe y') = 1

Trying To Find Tabes Without Primary Keys

May 29, 2008

I wrote a query that when run, will give me a listing of all tables in a database, and whether or not those table have primary keys.

Here's the query:




Code Snippet
select so.name, si.name from sysobjects so
left outer JOIN sysindexes si on so.id = si.id
where si.status = '2066' and so.type = 'u'
order by so.name asc


It works for the most part save for one small (big) problem. It gives me a list of tables that have a corresponding primary key, but doesn't list those without one. For example, in one database I run this query. I know for a fact that there are 26 tables in this database, and my query returns 16 rows (one for each table with a PK). I'd like to see those as well as those without one, with a NULL in the NAME column for the PK.

I've tried every join combo under the sun and still can't get the desired results.

Any insight would be appreciated!

Thanks!

Auto Incremented Integer Primary Keys Vs Varchar Primary Keys

Aug 13, 2007

Hi,

I have recently been looking at a database and wondered if anyone can tell me what the advantages are supporting a unique collumn, which can essentially be seen as the primary key, with an identity seed integer primary key.

For example:

id [unique integer auto incremented primary key - not null],
ClientCode [unique index varchar - not null],
name [varchar null],
surname [varchar null]

isn't it just better to use ClientCode as the primary key straight of because when one references the above table, it can be done easier with the ClientCode since you dont have to do a lookup on the ClientCode everytime.

Regards
Mike

How To List Tables With Primary Keys

Jun 9, 2007

Hello,We imported a bunch of tables from a database and realized that theprimary keys weren't copied to the destination db. In order to re-create the keys, we need to know which tables have them. Is there acommand that I can use (on the source db) to find out which tablescontain primary keys? The db has hundreds of tables and I'd rather notgo through each one to see which has a primary key.Also, for future reference, is there a way to include the primary keyon an import?Thanks,Peps

Primary Keys And Joining Tables

Aug 24, 2015

I've created a table called Employees with a primary key called EmployeeID.  The table contains EmployeeID, FirstName and LastName columns.  I now want to create a table called Team which will contain the columns TeamID, EmployeeID (to reference the column EmployeeID from the Employee table) and a column called TeamName.  Sql won't let me create multiple primary keys in one table (I did think that was the case ) key but yet if I look at the Adventure Works database in the Person.PersonPhone table, I can see three primary keys defined.

Correct Way Of Finding A Tables Primary Keys??

Aug 7, 2007

Hope this is in the right thread, sorry if not!

I have run into a problem, i need to find out that column(s) in a table that makes the primary key.
I thought that this code did the trick.
***
DECLARE @c varchar(4000), @t varchar(128)
SET @c = ''
SET @t='contact_pmc_contact_relations'
Select @c = @c + c.name + ',' FROM syscolumns c INNER JOIN sysobjects o ON o.id = c.id inner join sysindexkeys k on o.id = k.id WHERE o.name = @t and k.colid = c.colid ORDER BY c.colid
SELECT Substring(@c, 1, Datalength(@c) - 1)
***

This works in most of my cases. But i have encounterd tabels where this code doesn't work.
Here is a dump from one of the tabels where it doesn't work.
SELECT *
FROM sysindexkeys
WHERE (id = 933578364) <--id of the table
***
id indid colid keyno
933578364 1 1 1
933578364 1 2 2
933578364 2 1 1
933578364 3 2 1
933578364 4 3 1
933578364 5 4 1
933578364 6 5 1
933578364 7 6 1
933578364 8 7 1

Not sure if that dump made any sense, but i hope it did.
If i look at the table in SQL Enterprise manager there is no relations, no indexes only my primarykey made up with 2 columns (column id 1 and 2).

So, anyone know how i could solve this problem?

Alternative To Composite Keys..

Nov 20, 2007



Apologies if this is in the wrong place..



I have been reading a bit about db design practices for SQL server and have learned how bad composite keys are!

However, I just wanted to know what the accepted alternatives are (and why they should be used);



Previously I was under the impression that adding autonumber style keys to tables are bad (extra col, doesn€™t allow unique checking of tuples). I want a table which is made up of two (single) primary keys from other tables, but the entries in the new table to be unique (and efficient). (note this is going to be part of a db which is going to grow to become very large).



Thanks,

Kenny

Foreign And Composite Keys

Jul 30, 2007

Hi.

Could somebody please explain to me how to create a foreign key from a table that
has two composite keys? I have a table, UserPrecedence, with two composite keys -
up_owner, owner_userID. I have a second table, Users, that has the primary key
"emailAddress" and a userID table to which all other tables point their FK columns.

http://i103.photobucket.com/albums/m156/pbd22/Keys.jpg

I want the userID column in Users to be the FK of the owner_userID column in UserPrecedence
but the Modify Table view complains that "both sides of the relationship must have the
same number of columns" when I try to create the relationship.

I am guessing this is because its a composite primary key. Can somebody explain
to me how this is done correctly (and why)?

I appreciate your help.
Thanks.

Creating Inter-table Relationships Using Primary Keys/Foreign Keys Problem

Apr 11, 2006

Hello again,

I'm going through my tables and rewriting them so that I can create relationship-based constraints and create foreign keys among my tables. I didn't have a problem with a few of the tables but I seem to have come across a slightly confusing hiccup.

Here's the query for my Classes table:

Code:

CREATE TABLE Classes
(
class_id
INT
IDENTITY
PRIMARY KEY
NOT NULL,

teacher_id
INT
NOT NULL,

class_title
VARCHAR(50)
NOT NULL,

class_grade
SMALLINT
NOT NULL
DEFAULT 6,

class_tardies
SMALLINT
NOT NULL
DEFAULT 0,

class_absences
SMALLINT
NOT NULL
DEFAULT 0,

CONSTRAINT Teacher_instructs_ClassFKIndex1 FOREIGN KEY (teacher_id)
REFERENCES Users (user_id)
)

This statement runs without problems and I Create the relationship with my Users table just fine, having renamed it to teacher_id. I have a 1:n relationship between users and tables AND an n:m relationship because a user can be a student or a teacher, the difference is one field, user_type, which denotes what type of user a person is. In any case, the relationship that's 1:n from users to classes is that of the teacher instructing the class. The problem exists when I run my query for the intermediary table between the class and the gradebook:

Code:

CREATE TABLE Classes_have_Grades
(
class_id
INT
PRIMARY KEY
NOT NULL,

teacher_id
INT
NOT NULL,

grade_id
INT
NOT NULL,

CONSTRAINT Grades_for_ClassesFKIndex1 FOREIGN KEY (grade_id)
REFERENCES Grades (grade_id),

CONSTRAINT Classes_have_gradesFKIndex2 FOREIGN KEY (class_id, teacher_id)
REFERENCES Classes (class_id, teacher_id)
)

Query Analyzer spits out: Quote: Originally Posted by Query Analyzer There are no primary or candidate keys in the referenced table 'Classes' that match the referencing column list in the foreign key 'Classes_have_gradesFKIndex2'. Now, I know in SQL Server 2000 you can only have one primary key. Does that mean I can have a multi-columned Primary key (which is in fact what I would like) or does that mean that just one field can be a primary key and that a table can have only the one primary key?

In addition, what is a "candidate" key? Will making the other fields "Candidate" keys solve my problem?

Thank you for your assistance.
