what i got is there is 3 tables
1> category - Master table
2> profile - here employee with category(Transaction table)
3> project - here project in different category(Transaction table)
where category is common in profile and project.
select distinct profile.employeeid,project.projectname,project.categoryname
from project
inner join category on
category.catid = project.project_catid
inner join profile on
profile.prof_catid = project.catid
where profile.employeeid='a'
if above is correct Now tell me where r u not getting?

Both of you thanks for suggestions but its not working.
Let me make a final attempt to clear my issue
if I create a stored procedure as:
create procedure selectworks
(
@maincategory nvarchar(50)
)
as
select profile.category,
project.title,
project.subcategory,
project.expirydate from profile,project
where profile.category=@maincategory
and project.category=@maincategory
this is going to give me result for one category which i am going to provide( @maincategory)
but the issue is that the user has profiles in more than one category
if he has profiles in 3 categories this procedure should run for 3 times for 3 different categories but the result should come combined similarly if a user has profiles in 5 categories this procedure should run for 5 times for 5 different categories but should give combined result.
Thanks in advance..

1>First of all why you wants to pass category rather then employee id ???
2>if there is any necessity of passing category then you can use of
char index Or IN where you have to pass all the category separated by comma.
ex:- @maincategory='1,2,3'
1> CHARINDEX(',',@maincategory ) > 0
2> project.category IN (@maincategory)

I wonder why you don't want to use TOP, but here's another version:
SELECT Name, Salary
FROM TableName alias1,
WHERE 4 < (SELECT COUNT(*)
FROM TableName alias2
WHERE alias2.Salary > alias1.Salary)

I think that the Top will be the best choice, unless your using something other than SQL Server.
If your using MySQl, use Limit 3 at the end of the statement.
Select Salary
From tablename
Order By Salary Desc
Limit 3
I think any other method will cause overhang.

A view is a virtual table that consists of columns from one or more tables. Though it is similar to a table, it is stored in the database. It is a query stored as an object.
So what is the use of Views because i think one can do anything and everything with the tables without having Views...........
Plz explain ?????????

Views are faster and they hide the query complicity.

Hi,
Please go though the following articles for better explaination:

Hope this helps  .

Putting it simply, a View is a boon to security and simplifies your access to information. It's quicker in many respects than a full blooded table scan.
With a View we can grant access to the View without granting access to the underlying table thus limiting someone to only the data we wish them so access. Case in point, we could give a User access to a View from an employee table that omits SS# or salary information.
Does that answer your question?

View was designed for two purposes, security and query simplification as many people has already pointed out. Articles provided clarify these aspects well. However, a common misbelief is that a view is faster than a query without a view. This is not always true. There are several situations where views are slower than plain select statements.
When a view is created, it's stored as an object which gives the optimizer a possibility to create a better plan for the query. When executing view, some (but not all) of the parsing and optimization can be skipped and this can result in (small) performance benefit.
However creating a view does not significantly modify execution plan. For example if SELECT * FROM Customers results in a full table scan, the situation isn't typically any different if the statement is wrapped inside a view. Execution of the view can be boosted in several ways but they always require structural changes in the database (materializing, different kinds of indexing, partitioning, federations etc) so they require administration.
Since optimizer must be very careful when calculating permutations that it doesn't risk correct results, many default SQL optimizations are easily skipped if a query is executed against a view. Typical example is so called predicate pushing when optimizer tries to apply a condition as soon as possible. However if a view is defined, predicate pushing may not be used since it would modify view results hence modifying the overall results. This is just one of the many examples when query against a view can be (significantly) slower that plain query.

You cannot.
Ashish Kumar Vyas wrote: is there any other way to do this task.
You could look for a scripting tool. Modify the script to remove any SQL Server 2005 enhancements then run the script on SQL Server 2000 - It is still risky though.

i think you can not directly restore bak from SQL 2005 to 2000
but if you dont want data n want only structure n procedures of database
den u can use Generate script
|
|
|
|
|
thanx for replying...
but I need data too..
|
|
|
|

here is no "Restore" functionality, but there is a workaround to copy 2005 databases to 2000:
Right-click on DB -> tasks -> generate scripts
select DB and click "script all objects...", hit next
select any options you want, specifically changing "script for server version" to SQL Server 2000
next through and run the script
Now just export data from the 2005 database to the newly-created 2000 database.
Right-click on DB -> tasks -> export...
set source and hit next
set destination and hit next
select "copy data from one or more tables", hit next
select all, check "optimize for many tables" and "run in a transaction"
you may have to edit each table mapping and check "enable identity insert"
next through to finish
plz check it out
i hope dis will work 4 u
