Hello,
I need to write a script that creates a table variable with a column for every instance of a row in a table. The data in the table it pulls from may change from time to time, so I'm looking for a dynamic approach.
Example table:
ColumnA: ColumnB:
1 Hello
2 World
Then my table variable declaration should look like:
DECLARE @TableVariable TABLE
(
Hello varchar(20),
World varchar(20)
)
Can anyone think of a performance-friendly solution to this?
Thanks,
Kevin

I thing you should dynamically create an sql string that creates the table.
On the other hand, why would you want a to create a column for each row? suppose. Keep in mind that SQL Server has a max column limit of 255(or 256) per table.

Yes.. I think.
I encounted a similar issue this week and solved it by using a pivot table. There is an excellent article on hear that gives a workable example.
Pivot two or more columns in SQL Server 2005[^]
Hope this helps...

A pivot may do the job for you, organsing it will be a challenge.
Dynamic SQL is more straight forward EXCEPT if you use EXEC (@SQL) to create the table var it is created in a different proc domain and therefore not available to you. Creating a global ##Table will fix this but it is not recommended in a frequently called proc.Never underestimate the power of human stupidity

Thanks for the responses. I wish I could take the time to test these, but we have decided to move on - not making this a dynamic proc.

do you have any idea?

Have you tried typing the error message into Google? I did and I got 94,000 results; Maybe one of those could be of help?

order by users FirstName or LastName

If you want it ordered by either FirstName or LastName, then why does your original post also have an order by clause here;
<br />
ROW_NUMBER() OVER (ORDER BY aspnet_Membership.CreateDate ) AS RowNumber<br />
The ORDER BY in this context is in error.Chris Meech

I think you should not try to order intermediate results. You should only end-results.

|
|

can you change my SQL Statement as you think?
|
|
|
|

Actually, my answer was not correct. I think what's wrong with your query is the syntax i.e where the Order By Clause comes in. The syntax should be in form
ROW_NUMBER ( ) OVER ( [ <partition_by_clause> ] <order_by_clause> )

Thanks Silim it works
bt now I have anoter problem

do you hae any idea?

I am inserting different records using this this:
INSERT INTO prices (created_user, price_level_id, item_hour, item_category, item_code, item_description, item_price) SELECT @created_user, @price_level_identity, 0, item_category, item_code, item_description, item_price FROM prices WHERE price_level_id = @price_level_id AND item_hour = 0
INSERT INTO prices (created_user, price_level_id, item_hour, item_category, item_code, item_description, item_price) SELECT @created_user, @price_level_identity, 1, item_category, item_code, item_description, item_price FROM prices WHERE price_level_id = @price_level_id AND item_hour = 1
INSERT INTO prices (created_user, price_level_id, item_hour, item_category, item_code, item_description, item_price) SELECT @created_user, @price_level_identity, 2, item_category, item_code, item_description, item_price FROM prices WHERE price_level_id = @price_level_id AND item_hour = 2
I want after that to update the item_guid so all records having the same item_code should have the same item_guid, something like:
UPDATE prices SET item_guid = ONE_GUID_FOR-ALL where item_code = SAME_ITEM_CODE and price_level_id = WHAT_VER_ID_i_PASS

Try this:
declare @Guid uniqueidentifier
select @Guid = newid()
update prices set item_guid = @Guid ... rest of code.... Tychotics: take us back to the moon

I have a medical software and I want to know what's the best control to use and what's the best SQL field type for blood pressure?
The blood pressure as you know is in this format: 999/999
it also has a flag for either right hand (L) or left hand (R), something like radio control
I don't want the traditional way!! I mean two numeric and two radio?!
I thought of the ButtonEdit from DevExpress with a ###/### mask but I faced a problem with the L and R flags..
What is your advise?

Maybe you could have split the question into two and posted the db related part here?
How about creating a new table for storing the historical data (ReadingDate DATE, Side BIT, UpperReading INT, LowerReading INT). By doing this, you will have a history of readings as well as the current one.

My advice is never store multiple pieces of data in one column unless you absolutely can't avoid it. Systolic pressure and diastolic pressure are distinct pieces of data and should be recorded separately. Do you have a valid reason for avoiding the "traditional" way?
To show you why they should be stored separately here is part of a blood donation form. "Donors must have blood pressure values of 180 or less for the top (systolic) number and 100 or less for the bottom (diastolic) number. Donors with values greater than 140/90 may wish to consult their personal physician." So as you can see, the numbers for eligibility are different than the numbers where you should be concerned. Not only that, but the difference between the concern and max numbers is different for the two pieces of data. So if anyone ever wanted a report where the pressure was above the rate of concern, but below the maximum for donation that query would be much more difficult to write if you combined the data. You also couldn't do proper sorting.

well, i won't have issue saving it separately in the sql server but I don't want many controls on the form? so what's the best way to have some thing like a mask of 999/999 Left or 999/999 Right?

how to roll back whole tran if Violation of UNIQUE KEY constraint hep pend

this may work for you easily
