A Query To Find Primary Key
Sep 4, 2007
I 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,
t.is_assembly_type,
c.max_length,
c.precision,
c.scale
FROM
sys.columns AS c
JOIN sys.types AS t ON
c.user_type_id=t.user_type_id
WHERE c.object_id = OBJECT_ID('Contact') ORDER BY c.column_id;
Thnx
Matt

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

I 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

This 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?

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!

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 am trying to run an insert query off of a sql datasource and I am erroring out. My code and stored procedure as of now are listed below. You will notice the section of the stored procedure that is pulling the value for facility_ID (primary key). I have also tried to pull these and pass the parameter from a label, but that does not work, giving an error that the stored procedure expects the parameter @Facility_ID which was not supplied. One other odd thing is that stepping through the code, I watched the parameter count total 21, but when running the insert command, the insert parameter count shows 20. With the code below (my current project), I get an error that null values can not be entered for facility_ID. Please help.

My table consists of about 1.4 Million Records. The PK is a CHAR field and ranges in size from 3 - 25 characters. I need to pull a recordset using the LEFT function.
Example: SELECT blah WHERE LEFT(myPK, 8) = 'AIRBILLNU'
This query takes about 115927ms to run and the server is 100% CPU bound, it should only bring up 2 records. Seems like the index is not being used. I know the DB design is probably not the greatest, we probably should have had an INT PK and IX on the other field which is now the PK. I cannot do anything about that at this point.
Is there anything I can do to speed up this query.?
Thanks,Adrian

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)

I am writing a query to display the count of products when a month is the primary month (Month where large sales happened)..Please consider the following query..
With Member ProductRank as
Rank([Date Due].[Calendar].currentmember,TopCount([Date Due].[Calendar].[Month],1,[Measures].[Sales Amount]))
Member PrimaryProd as
Count(Filter([Product].[Product].[Product],[Measures].ProductRank=1))
Select PrimaryProd on 0, Order([Date Due].[Calendar].[Month],PrimaryProd,bdesc) on 1 from [Sales]
Output:
It runs for 13 seconds on my laptop. I have modified the query to get the results fast like With
Set MySet as TopCount([Date Due].[Calendar].[Month],1,[Measures].[Sales Amount])
Member ProductRank as
Rank([Date Due].[Calendar].currentmember,MySet)
Member PrimaryProd as
Count(Filter([Product].[Product].[Product],[Measures].ProductRank=1))
Select PrimaryProd on 0, Order([Date Due].[Calendar].[Month],PrimaryProd,Bdesc) on 1 from [Sales]
Output:
This query runs instantly and result is not the same. Am I missing something here?

Hi
I am trying to find when a name has been entered more than once into 1 database table.
I'm currently doing something like this (can't remember exactly, not at work)
SELECT COUNT(*) AS Cnt, Name
FROM tblTable
GROUP BY Name
ORDER BY Cnt Desc
This brings back all the Names in the database and tells me which are duplicates but I want to just have the results of the duplicate values and not the single values.
Hope you can help.
Thanks

We had 10 scheduled jobs, which run more then 1000 Stored Procedures. I want to map the flow of dependency in Stored Procedure. Like SP 100 is dependent on SP 10, and SP10 was dependent on SP1 in our processing. If SP10 fails, we have to rerun SP1, SP10 and SP100 from Query analyzer. I was looking for a query or method to do find out flow of dependency in Stored Procedure.

I've been struggling with this one for quite some time now and would appreciate some help:-
I'm trying to get a list of schools that only has male students. the closest I have so far:-
SELECT Schools.SchoolName, FORUM_MEMBERS.M_SEX , COUNT(Schools.SchoolName) AS no_of_students
FROM Schools
INNER JOIN FORUM_MEMBERS ON (Schools.SchoolID = FORUM_MEMBERS.SchoolID)
WHERE (FORUM_MEMBERS.UserType=4)
GROUP BY Schools.SchoolName, FORUM_MEMBERS.M_SEX
ORDER BY Schools.SchoolName, FORUM_MEMBERS.M_SEX;
The result is a list of schools:-
SchoolName, M_SEX, no_of_students
school 1, Male, 11
school 1, Female, 20
school 2, Male, 8
school 2, Female, 1
school 3, Male, 12
school 4, Male, 14
school 5, Male, 8
school 5, Female, 1
But what I really need is schools with only male students:-
SchoolName, M_SEX, no_of_students
school 3, Male, 12
school 4, Male, 14
Many Thanks
