The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

MS SQL Altering table to set primary key NON CLUSTERED

Asked by isaackhazi in SQL Server 2008, SQL Server 2005, SQL Query Syntax

Tags: MS SQL Server, SQL SERVER 2008

I have converted around 395 Excel survey forms to MS SQl database with that many tables. Well, I run a script to assign a primary key on all the tables on my database.First I set the column property to NOT NULL and then i assign the primary key to it. I assign the primary key to a column called 'FPC_Code'. This column contains values such as, _C2348787, _C567489 etc etc......Well, my problem is that WHEN I ASSIGN THE PRIMARY KEY TO ALL THE TABLES THEY GET SORTED WRT THE FPC_Code column. I dont want this sorting to take place. I need it to remain unsorted as they are survey forms and would like to preserve the order.

I figured that by default MS SQL Clusters the Primary key and thats why they get sorted. I want to know how to assign a primary key to a column without clustering it. I have attached the script i run on my database.

All I want to know is How to use the ALTER table with the primary key so that the primary key is not clustered.

             DECLARE Alter_tables_cursor CURSOR
   FOR
   select table_name from information_schema.tables where table_name<>'dtProperties' and table_type<>'VIEW'
OPEN Alter_tables_cursor
DECLARE @tablename sysname
FETCH NEXT FROM Alter_tables_cursor INTO @tablename
WHILE ( @@FETCH_STATUS = 0 )
BEGIN
 PRINT 'Altering  Primary Key -->'+@tablename+' '
 EXEC('ALTER TABLE '+@tablename+' ADD PRIMARY KEY (FPC_Code)')
 FETCH NEXT FROM Alter_tables_cursor INTO @tablename
 
END
PRINT 'All user-defined tables have been Altered.'
DEALLOCATE Alter_tables_cursor
