Hi,
I'm kind of confused on this.
If I have data on tables, and I'd like to know something which is deducted from that data, but requires several tables and calculations.. should I make that "something" an explicit data (table, attribute, who knows)?
For example:
I have a table of "goals", "matches" and "teams" of some football tournament.
and I want to know the number of win matches of some team, then I would have to calculate them by comparing the number of goals, etc etc.
But if Id put a column of "WonGames" in the table of teams, then this wouldnt be needed
What is the correct approach?
Thanks

Deduced?
With some such things, you might want to do both; have a detailed transaction table and a summary table.

continuuing from PIEBALDconsult, this is why a good deal of time usually goes into data analysis (and sometimes even then it takes multiple evolutions to get it right)
If dynamically recalculating the result(s) each time starts getting onerous or you need them elsewehere and dont wish to use temp tables for example, you may need to maintain a transaction table as he suggests

P.S.

Then I think you could only track one season at a time; you may need a season table -- which might be a good place to store such summary data.

Determining the "cost" of recalculating the results. If it takes a lot of time to reproduce the data, then store it

Hi guys.
i want join the results this table below with matching records of another table. How could i do it. I have tried using the right join on class table but seems like not getting the right results. could you hlep me joining the class table with all all those records are only in class table.
Thanks
select ucv.cf_value+', '+ucv2.cf_value as FullName
from users u
left join CUSTOM_FIELDS_VALUE ucv on ucv.cf_id=3
left join CUSTOM_FIELDS_VALUE ucv2 on ucv2.cf_id = 2
right join class on class.instructorName= ucv.cf_value+', '+ucv2.cf_value
where u.uid=ucv.uid and u.uid=ucv2.uid
order by ucv.cf_value+', '+ucv2.cf_value asc

Oh dear have you got a problem. Looks like you are using the instructors name as a key field for joining tables - WRONG. Each table should have an ID field (usually and int IDENTITY(1,1)) as the primary key and then a foreign key to maintain data integrity.
Your join structure is wrong. A left join to UCV2 and THEN a right join the to class means that you will get records, wait I'm have no idea what you would get but it would be a mess.
Take a look at this Visual Representation of SQL Joins[^] for some clarification

Hello -
I'm in the process of using a script that will help with re-indexes. I keep getting the following errors.
Msg 102, Level 15, State 1, Line 2
Incorrect syntax near '('.
Msg 156, Level 15, State 1, Line 10
Incorrect syntax near the keyword 'ELSE'.
My database name is Backdrop and the table is dbo.PJTRAN and the index is pjtran0. Here is the script if someone can help me understand why I keep getting those errors.
IF EXISTS (SELECT [object_id],[index_id],[avg_fragmentation_in_percent] FROM sys.dm_db_index_physical_stats
(DB_ID(N'Backdrop'), OBJECT_ID(N'PJTRAN.PJTRAN0'), NULL, NULL , 'DETAILED')
WHERE [avg_fragmentation_in_percent] < 30)
BEGIN
ALTER INDEX ALL ON PJTRAN REORGANIZE
END
ELSE
ALTER INDEX ALL ON PJTRAN REBUILD
Thank you..

Have you executed the script in Query Analyzer?
|
|
|
|
|
This is for a SQL 2005 database. I'm using SSMS.

If what exists, the structure does not make sense, you are selecting a row and then ask if something exists. Change the script to:
DECLARE
@Count INT
SELECT @Count = COUNT(*)
FROM sys.dm_db_index_physical_stats
(DB_ID(N'Backdrop'), OBJECT_ID(N'DBO.table'), NULL, NULL , 'DETAILED')
WHERE [avg_fragmentation_in_percent] < 30
IF @Count > 0

Could it be the concatenated name in my FROM clause?
Also note that when it wasn't in dynamic sql it worked fine. We were fighting with the WHERE clause and needed that to be dynamic. I just couldn't find a way to make the Statement (SELECT AND FROM) static and the WHERE dynamic and have it work.
Any suggestions?
Thanks

Without attempting to run it myself if I get these errors with dynamic sql I always do a quick print @sql and see what I've got. Copy it into a new query window and run it. That should give you more of an idea.

This worked and it was the concatenation of the FirstName and LastName's
Thank you again for the time.

Yup, that was on Line 4 [of the dynamic part] - exactly as the error message prompted.

Pls is it possible to generate crystal report from dataset created in code at runtime?
Thanks.
|
|
|
|
|
Short answer is Yes.
Have your application create a dataset, then assign the dataset to the CrystalReportViewer and you're done.
There are lots of examples of using Crystal Reports here in Code Project, just search them out.

pls i have done this already, i get an error: this report does not have a table.
pls help.
thanks

Could I write this as a exists statement we use this quite often and I read it has very poor performance.
WHERE `cl_client_common`.`UniqueNumber-900` IN(5337, 4439, 4725, 4096, 8078, 5912, etc, etc)
We do not know what the values will be until the user selects the clients they want.
All of the examples I see are using a subquery for the EXISTS statement and the only way I can think to write that with a subquery would be to use an IN in the subquery.
Thank you any help is appreciated.

If you are storing the list of numbers in a temp table or similar, you could use
WHERE `cl_client_common`.`UniqueNumber-900` IN (select NUMBER from TEMPTABLE)
or simply by doing an inner join to the temp table...
Otherwise, the way you are doing it will have to do!!
