I 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 can i find the primary field name and primary table name of a given foreign key.
For example
Table A:
IDa
Column1
Column2
Column3
Table B:
IDb
column1
column2
column3 <---- this is foreign key to table A's IDa
What i want to do is i pass input of tableB, column3 and i get name of Primary tableA and field name IDa. How is it possible to do in tsql ?
in my database?

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

This ain't working
SELECT T.TABLE_NAME,C.COLUMN_NAME

JOIN INFORMATION_SCHEMA.COLUMNS C
ON T.TABLE_NAME = C.TABLE_NAME
WHERE OBJECTPROPERTY(OBJECT_ID(T.TABLE_NAME),
'TableHasIdentity') = 0

This is giving me bogus results...
SELECT * FROM INFORMATION_SCHEMA.COLUMNS

I have PK's all over the place. What gives? Too many cocktails with lunch?
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!
...got tired of looking at them by hand.

Can anyone suggest me on Adding primary key to a table which has already a primary key.

I 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.
I have 3 database say
db1
db2
db3

I need to add a child table that will tell us who the participants counselor is, what I did was I did a Make Table query based off the primary key of the Parent table and made that the link (foreign key) for the People_tbl and the Counselor_tbl, so if the counselor changes then the user adds the record to the counselor tbl and then puts in the Effective date. The problem is that when I run a report it doesn't show the present counselor always shows the old counselor?
Code:

Previously same records exists in table having primary key and table having foreign key . we have faced 7 records were lost from primary key table but same record exists in foreign key table.

Hi i have set up two very simple tables, I want a user to be able to create a basic account ( data stored in User_Profile table with Id set as the Primery Key as Identity) I
want the user to be able to be able to return to their account at a later date
and then post multiple reviews of different bands they have seen at a later date.
I kept the tables in my example very simple so I could get my head
around the concept, but generally, I want to connect the Id (PK) value in
User_Profile table to the User_Id filed in the User_Review table,
so every review that user writes, will be connected directly to their Id.
Any help you could give would be fantastic a i have no idea where to start!!!
User_Profile
Id int, ( as primary Identity Key)
Name
City
Country
I have a second table called User Reviews
User_Revews
Revew_Id int , ( as primary Identity Key)
User_Id int, ( I want this to contain the Id value in
the User profile Table)
Review_Details
Thanks

Hi,
I have a Users table that I use for membership. I am using username varchar(30) as the primary key for this table since username will always be unique.
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 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 99,999 rows will have to move.
Bottom line, insert, delete will be very 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 have table 'stores' that has 3 columns (storeid, article, doc), I have a second table 'allstores' that has 3 columns(storeid(always 'ALL'), article, doc). The stores table's storeid column will have a stores id, then will have multiple articles, and docs. The 'allstores' table will have 'all' in the store for every article and doc combination. This table is like the master lookup table for all possible article and doc combinations. The 'stores' table will have the actual article and doc per storeid.
What I am wanting to pull is all article, doc combinations that exist in the 'allstores' table, but do not exist in the 'stores' table, per storeid. So if the article/doc combination exists in the 'allstores' table and in the 'stores' table for storeid of 50 does not use that combination, but store 51 does, I want the output of storeid 50, and what combination does not exist for that storeid. I will try this example:
'allstores' 'Stores'
storeid doc article storeid doc article
ALL 0010 001 101 0010 001
ALL 0010 002 101 0010 002
ALL 0011 001 102 0011 002
ALL 0011 002
So I want the query to pull the one from 'allstores' that does not exist in 'stores' which in this case would the 3rd record "ALL 0011 001".
There is a restriction that we must have only one primary key per table. We can have composite primary key by defining primary key over 2 or more columns. Actually,, a primary key uniquely defines the table and if we have two or more columns which follow unique and not null features why can't we have two primary keys?? I want to know what is the main reason behind having only one primary key in a table??
View 3 Replies View RelatedI ran into a table that is used a lot. Well less than100,000 records. Maybe not a lot of records but i believethis table is used often. The table has 26 fields, 9 indexesbut no Primary Key at all!There are no table relationships defined in this database, noNatural keys, only Surrogate keys in the database.1- Maybe an odd question but is it normal to have 1/3 of thetable's fields as indexes? Is this a valid question or it reallydoesn't matter if you have 9 indexes if they are appropriate to beindexes?2- Below is the DDL of the indexes (Is DDL the appropriate termto describe the indexes?)
