Find Primary Key On Table.
Feb 26, 2008I need to find the primary key of a table, in MySQL i used SHOW COLUMNS and looped through them to find which one was primary if any. The MSSQL equivalent is SELECT * FROM INFORMATION_SCHEMA.Columns WHERE TABLE_NAME = 'table_name' apparently. However the result doesnt give me any key information. How can i find out
1. if a primary key exists on a table
2. what column that primary key exists on
How Do You Find A Primary Key Violation
Jan 11, 2005I need to find out which record I am violating by trying to execute this stored procedure
ALTER PROCEDURE InsertCorovan2004
AS
INSERT INTO [GamingCommissiondb].[dbo].[Corovan_Table]
([TM #],
[FirstName],
[LastName],
[SS #],
[TerminationDate],
[Voluntary or Involuntary])
SELECT [TM #], FirstName, LastName, SocialSecurityNumber, TerminationDate, VoluntaryorInvoluntary
FROM dbo.TERMINATION
WHERE (TerminationDate BETWEEN CONVERT(DATETIME, '2004-01-31 00:00:00', 102) AND CONVERT(DATETIME, '2004-12-31 00:00:00', 102))
GO
when I execute it I get this error message
Server: Msg 2627, Level 14, State 1, Procedure InsertCorovan2004, Line 3
Violation of PRIMARY KEY constraint 'PK_Corovan_Table'. Cannot insert duplicate key in object 'Corovan_Table'.
The statement has been terminated.
Stored Procedure: GamingCommissiondb.dbo.InsertCorovan2004
Return Code = -4
I am trying to insert 2004 terms into the corovan table from TERMINATION table. How do you find out what records match from each table (compare the tables reocords for dups). How would I do this in the query analyzer since thats mainly what I use. I get a better understanding of how to create proceudure in the query analyzer so I;d rather stick to it.
In short I need to find the Culprit record that is preventing me from insert the 2004 records
Thank you

Sep 4, 2007I have a query that can tell me the columns in a table. In this case "Contact". What I would like to add to my query is if the column is part of the primary key. Can that be done? how so?
Code Snippet
SELECT
c.name AS column_name,
c.column_id,
SCHEMA_NAME(t.schema_id) AS type_schema,
t.name AS type_name,
t.is_user_defined,

Trying To Find Non Identity Primary Keys
Jan 26, 2006This ain't working
SELECT T.TABLE_NAME,C.COLUMN_NAME
FROM INFORMATION_SCHEMA.TABLES T
JOIN INFORMATION_SCHEMA.COLUMNS C
ON T.TABLE_NAME = C.TABLE_NAME
WHERE OBJECTPROPERTY(OBJECT_ID(T.TABLE_NAME),
'TableHasIdentity') = 0
AND T.TABLE_TYPE = 'BASE TABLE'
AND OBJECTPROPERTY(OBJECT_ID(C.COLUMN_NAME),'IsPrimary Key') = 1
ORDER BY T.TABLE_NAME,C.COLUMN_NAME
This is giving me bogus results...
SELECT * FROM INFORMATION_SCHEMA.COLUMNS
WHERE OBJECTPROPERTY(OBJECT_ID(COLUMN_NAME),'IsPrimaryKe y') = 1
I have PK's all over the place. What gives? Too many cocktails with lunch?
Trying To Find Tabes Without Primary Keys
May 29, 2008I 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!

SQL Server 2012 :: Find Queries That Lock Tables Or Not Using Primary Key While Running Update
Jul 20, 2015I need to search for such SPs in my database in which the queries for update a table contains where clause which uses non primary key while updating rows in table.
If employee table have empId as primary key and an Update query is using empName in where clause to update employee record then such SP should be listed. so there would be hundreds of tables with their primary key and thousands of SPs in a database. How can I find them where the "where" clause is using some other column than its primary key.
If there is any other hint or query to identify such queries that lock tables, I only found the above few queries that are not using primary key in where clause.

Auto Incremented Integer Primary Keys Vs Varchar Primary Keys
Aug 13, 2007Hi,
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
Anything That You Find In SQL Object Scripts, You Can Also Find Them In System Tables?
Jul 26, 2005I tried all the INFORMATION_SCHEMA on SQL 2000 andI see that the system tables hold pretty much everything I aminterested in: Objects names (columns, functions, stored procedures, ...)stored procedure statements in syscomments table.My questions are:If you script your whole database everything you end up havingin the text sql scripts, are those also located in the system tables?That means i could simply read those system tables to get any informationI would normally look in the sql script files?Can i quickly generate a SQL statement of all the indexes on my database?I read many places that Microsoftsays not to modify anything in those tables and not query them since theirstructure might change in future SQL versions.Is it safe to use and rely the system tables?I basically want to do at least fetching of information i want from thesystem tables rather than the SQL script files.I also want to know if it's pretty safe for me to make changes in thesetables.Can i rename an object name for example an Index name, a Stored Procedurename?Can i add a new column in the syscolumns table for a user table?Thank you

View 2 Replies View Related4 Key Primary Key Vs 1 Key 'artificial' Primary Key
Jan 28, 2004Hi all
I have the following table
CREATE TABLE [dbo].[property_instance] (
[property_instance_id] [int] IDENTITY (1, 1) NOT NULL ,
[application_id] [int] NOT NULL ,
[owner_id] [nvarchar] (100) NOT NULL ,
[property_id] [int] NOT NULL ,
[owner_type_id] [int] NOT NULL ,
[property_value] [ntext] NOT NULL ,
[date_created] [datetime] NOT NULL ,
[date_modified] [datetime] NULL
)
I have created an 'artificial' primary key, property_instance_id. The 'true' primary key is application_id, owner_id, property_id and owner_type_id
In this specific instance
- property_instance_id will never be a foreign key into another table
- queries will generally use application_id, owner_id, property_id and owner_type_id in the WHERE clause when searching for a particular row
- Once inserted, none of the application_id, owner_id, property_id or owner_type_id columns will ever be modified
I generally like to create artificial primary keys whenever the primary key would otherwise consist of more than 2 columns.
What do people think the advantages and disadvantages of each technique are? Do you recommend I go with the existing model, or should I remove the artificial primary key column and just go with a 4 column primary key for this table?
Thanks Matt
Primary Key
Aug 31, 2006Hello all,I'm taking over a project from another developer and i've run into a bit of a problem. This developer had a bad habit of not using primary keys when designing various databases used by his programs. So now i've got approx 1000 tables all of which do not have primary keys assigned. Does anyone know of a tsql script that i can run that will loop through each table and add a primary key field?Thanks in advance?Richard M.

Primary Key
Nov 8, 2007Hi..
I'm going to build database of university, but I have problem with primaru key,
This is the situation:
there are many faculities and each one has many departments,
each department has many courses,
each course has many sections..
The problem:
I want to make those fields in the same table and make the primary key generate from other fields,
(i.e)
I want the faculity be integer from 4 digit "Example the first faculity start with 1000 the second 2000 and so on" and the the department of each faculity will generate its value from the faculity number+interger number from 3digit "Example the department of the first faculity start with 1100 and the second on will be 1200 and so on "
the same thing will repeate for courses and sections so the sectionsID will be the primary key.
Do you know hoew this idea can be implement by SQL server 2005?
Please help me as soon as possible.

DTS Is Not Getting The Primary Key
Jul 8, 2004Hi All,
Using DTS i have imported the data from sybase to MS SQL server and all the data and tables were imported correctly.But the primary keys are not marked why is it like this?

Primary Key
Sep 23, 2004I am setting up some tables where I used to have an identity column as the primary key. I changed it so the primary key is not a char field length of 20.
Is there going to be a big performance hit for this? I didn't like the identity field because every time I referenced a table I had to do a join to get the name of object.
EG:
-- Old way
tbProductionLabour
ID (pk)| Descr | fkCostCode
----------------------
1 | REBAR | 1J
tbTemplateLabour
fkTemplateID | fkLabourID | Manpower | Hours
--------------------------------------------
1 | 1 | 1 | 0.15
-- New way
tbProductionLabour
Labour | fkCostCode
---------------------
REBAR | 1J
tbTemplateLabour
fkTemplateID | fkLabour | Manpower | Hours
-------------------------------------------
1 | REBAR | 1 | 0.15
This is a very basic example, but you get the idea of what I am referring to.
Any thoughts?

Datefrom
DateTo
.... what would be the primary key?! I know it would be DateTo and sumfing...... Since Heading2 and Heading3 could be null, they cannot be PK... and heading1 cannot be a PK because the following three DIFFERENT options could have the same heading1
Option 1) heading1 = "X" heading2 = Null heading3 = Null
Option 2) heading1 = "X" heading2 = "Y" heading3 = Null
Option 3) heading1 = "X" heading2 = "Y" heading3 = "Z"
... but I need a PK to make sure a bonus is not entered twice... I considered added an Id, but them how do I assign a id?! what would i make the id equal to???
