Hi,
I have some questions about making muliple T-SQL queries againt an SQL-server. I retrieve all rows from an SQL-server table called ActivityGroup and add the result to a Radio Button List. Suppose, I also wish to add the total sum of every "ActivityGroup" value to the Radio Button List. I guess this ought to be done using a SELECT COUNT statement and then retrieved using the Executescalar method?
The question is do I need to copy the code for the SELECT ('*) statement and make the neccessary changes for the SELECT COUNT statement and Executescalar method or is there a more simple way? Is it possible to use two command statements in the same code block?
The total sum is going to be calculated using the values from both an SQL-server and an Access database. The OleDb sample below is what I refer to as a code block. I appreciate any help!
string connectionString = ConfigurationManager.ConnectionStrings["ServetteConnectionString"].ConnectionString;
string sQuery = "SELECT * FROM Aktivitetsgrupper where aktivitetsid = " + Request["AktivitetsId"];
OleDbConnection oOleDbConnection = new OleDbConnection(connectionString);
oOleDbConnection.Open();
OleDbCommand command = new OleDbCommand(sQuery, oOleDbConnection);
OleDbDataReader reader = command.ExecuteReader();
int test = 12;
while (reader.Read())
{
rblAktivitetsgrupper.Items.Add(new ListItem(String.Format("{0}, platser", reader["aktivitetsGruppNamn"]), reader["aktivitetsGruppID"].ToString()));
}

I have a few questions related to using CONTAINSTABLE in a query that I hope someone can help with.
I am working on a project to add document search capabilities to my companies product using fulltext indexing. Part of this requirement is an ability to breakdown the component parts of of the search query and provide information on *why* documentX ranked higher than documentY.
This is a bit convoluted, but taking this (very simple) example - the user wishes to search for 2 skills - "HTML" and/or "XML".
The generated query looks a little like :-
Select DOC.DOC_ID, RANK1.RANK, RANK2.RANK, RANK3.RANK
from DOCS DOC
inner join CONTAINSTABLE(docs, doc, 'HTML AND XML') as RANK1 on RANK1.DOC_ID=DOC.DOC_ID
inner join CONTAINSTABLE(docs, doc, 'HTML') as RANK2 on RANK2.DOC_ID=DOC.DOC_ID
inner join CONTAINSTABLE(docs, doc, 'XML') as RANK3 on RANK3.DOC_ID=DOC.DOC_ID
This returns the "overall" rank, and a rank for the 2 component parts, so I can say this doc ranked XXX overall because it scored "rank1" for HTML and scored "rank2" for XML etc....
My question on this part is about the values for the "overall rank". If the query contained an OR it always seems to return the highest of the "rankX" values, and if it doesnt, it returns the lowest.
e.g. for the example
for java and word and excel and access - the overall ranking is 2 , java=36, word=2, excel=16 and access=36
for java and word or excel and access - the overall ranking is 16 , java=36, word=2, excel=16 and access=36
for (java and word) or (excel and access) - the overall ranking is 16 , java=36, word=2, excel=16 and access=36
So in the first example, regardless of what the other values are, the rank returned is always 2 (the score for "word"). My resultset has 100ish rows, all with a rank of < 5 for word, but all with ranks of 18-100 for the other 3 values - yet the "overall" rank always matched the "word" rank.....??
This doesnt feel right to me somehow, I would expect a different value as if the document ranked really highly for one value but low for the other, it doesnt feel right the value is clamped to the lowest? Or am I just understanding it wrong?
If I use "freetexttable" the overall rank is a little more meaningful - but unfortunately I also need to use weighting, which brings me to my next question . . .
This question is about rankings returned from the ISABOUT function.
In the following example,
select * from documents as DOC
inner join containstable(docs,doc,'project') as doc0 on DOC.DOC_ID=doc0."key"
inner join containstable(docs,doc,'ISABOUT (project weight (1.0))') as doc1 on DOC.DOC_ID=doc1."key"
inner join containstable(docs,doc,'ISABOUT (project weight (0.5))') as doc2 on DOC.DOC_ID=doc2."key"
inner join containstable(docs,doc,'ISABOUT (project weight (0.1))') as doc3 on DOC.DOC_ID=doc3."key"
inner join containstable(docs,doc,'ISABOUT (project weight (0.0))') as doc4 on DOC.DOC_ID=doc4."key"
order by doc0.rank desc
The values I get from the doc1/2/3/4.RANK columns dont seem right.
In this example,
doc0.rank = 133
doc1.rank = 150
doc2.rank = 330
doc3.rank = 924
doc4.rank = 0
These values dont make any sense to me, as the rank seems to go UP when the documentation on ISABOUT says it goes down (I think it says somewhere the calculated rank is multiplied by the weight?).
Once again, is there something I missed or am I understanding it wrong?
Thanks in advance for any help into understanding the whys of this...

Hello,I am trying to create a view that shows the followingField1: Sum of Amounts from Table AField2: Count of Amounts from Table AField3: Sum of of Amounts from Table BField4: Count of Amounts from Table B......Field3: Sum of of Amounts from Table HField4: Count of Amounts from Table H......Things are a bit more complex but this is the gist.I am using SQL 2000.I know how to do this pretty easily using a stored procedure. But howcan I do it in a view? A SQL server won't meet my needs in thissituation.I tried OpenQuery ('myserver', 'exec myprocedure') but get the messagethat my server is not configured for data access. I tried the systemstored procedure to set data access to true but nothing seemed tohappen.I also tried Select * from (Select Statement1, select statement2)but got syntax error at the comma between statement1 and statement2.Trying to use select Statement1 as ABC to does not seem to work either.Is there a way to do what I want without making 15 views and then afinal view that shows them all together? I know I could probably dosomething by creating a ton of functions, but it really seems thisshould not be that hard...I am definitely open to any easy suggestions!Thanks,Ryan

Greetings everybody,
lately we are experiencing some very strange behaviour on the part of our
SQL-Server.
We are using SQL-Server as a combined Database for one COM+ application and one J2EE-Application. All of this is installed on the same machine (dual-CPU, 2 GB RAM).
This setup has been up and running for almost a year now.
In the last two weeks there have been incidences where the performance of SQL-Server is decreasing steadily until it finally hangs completely (just SQL-Server, not the machine itself).
This happens 2-3 times a week, curiously always between 9 and 10 a.m.!
After stopping and restarting the actual SQL-Server "Service", everything is back to normal (until the next morning or the morning after that).
There are a few automated batches that access the database via the COM+ Server. These run at night and are completed before work begins at ca. 7 a.m.
Profiler-Logs show a few "Escalate Locks", but those alone cannot account for this strange behaviour.
Any help or info would be greatly appreciated.

Hi,
A Composite entity can be made out of two Primary Keys (PK) of two different entities. Therefore it can be called as a link table. Therefore the composite entity depends upon the other two entites. Therefore the composite entity is a exsitence dependent on the other two entities.
Therefore do every composite is a weak entity?

I hope I can explain this somewhat coherantly. Here goes..
I have a products database. I want to select product details for items having distinct style codes. IE if there are 20 products that different from one another in some way, and 3 different style numbers throughout them, I want to end up with 3 products selected. I don't care which ones, as long as i have a sample product for each style.
I've attemped to use GROUP BY to do this, but it's not giving me what I want. I managed to get right number of products, but the query seems to have mixed and matched the fields together in an undesireable way. I guess this kinda makes sense, since providing aggregate functions for each of the extra fields is necessary.
SO THE QUESTION IS: How do I select (number of distinct styles) products, and still keep the records in tact as they should be?
Here is a sample...
Code:
SELECT DISTINCT Min(team) as team, min(pict) as pict, min(colors) as colors, min(league) as league, min(product_description) as product_description, min(category) as category, min(subcategory) as subcategory, min(style) as style
FROM prods
WHERE (style='style1' or style='style2' or style='style3')
AND league='leaguex'
AND soldout=''
GROUP by style
ORDER by style
Thanks very much for any help!! I'm sure I'm going about this all wrong.

Hello Everyone,
I have a dimension that has the following members:
Directors
Senior Managers
Managers
Senior Associates
Associates
But they way they need to be displayed includes subtotals. Senior Managers and Managers are placed into Management and Staff is a total of everyone except Directors. They should appear on the report in something like this:
Directors 10
Senior Managers 15
Managers 9
Management 24
Senior Associates 17
Associates 40
Staff 81
Total 91
What is the best way to do this? Right now I am using a matrix because I am also showing headcounts by Period. Is a table a better way to go? Is it something that should be done in my dimension?
I can do the Total part. I am just not sure how to make the subtotals inbetween the other lines.
Thank you for the help.

I have been reading up on how replicating schema changes work, but I must be missing something. When I configured a database for replication, it added a rowguid column to each table. This I understand.
I want to test making a schema change and replicating that change. For example, I tried to add a column to an existing table. When I tried to save the table i get the following error:
"Error validating the default for column rowguid".
"- Unable to modify table.
It is invalid to drop the default constraint on the rowguid column that is used by merge replication.
The DDL operation failed inside merge DDL replication manipulation.
The transaction ended in the trigger. The batch has been aborted."
So, what am I missing? Do i need to drop the rowguid column, add the new column, and then re-add the rowguid column?
Many thanks...

Hi,
I have the following flow in which i am looping through a folder containing textfiles
Foreach loop
[
ScriptTask -> DataFlowTask -> Execute SQL
]
In my ScriptTask, i am checking the file validity. Now if the file is found incorrect, I do not want the DataFlowTask and other to execute. Instead i want the file to be moved to Error and the loop to proceed with the next file. If the file validity is correct, DFT and ExecuteSQL execute. How do i do this?
Some explanation supported by examples would help.

I have a datagrid in my file along with an Update Query.
My Update Query basically adds the numerical values in two columns
together when the page is loaded. This means whenever the page is
Refreshed the Update query is fired.
This is my Update Query (which is in an Stored Procedure):
UPDATE Rental
SET TotalFee = ExtraFee + TotalFee
WHERE DaysOverdue >= 0
I have declared my query in the 'Page_Load' part of the coding, because
I want the query to run automatically. Not manually by a button.
My main question is that how can I get the query to run only once a day, no matter how many times the page is loaded.

Playing with DTS for converting text data to SQL Server table and sending email messages. Package is to be scheduled hourly.
1. Is there any easy way to force DTS to choose Success or Failure based on a SQL Task? Wish to check contents of a table for new values and branch accordingly in DTS.
2. When new records are brought in I wish to build a custom email message rather than attaching a text file. Any Idea how to build a custom message?
I am attempting to auto scan an error log on a Unix based system and email myself when errors occur. This is an exercise to test scheduling of jobs, bridging between technologies and sending out meaningful messages based on the process via email.
Thanks,

Is there any possible way to make a row delete itself at a certain date and time? I am tring to make an "On_Sale" table and perticular items(rows) must expire at a certain Date and time. I have an idea to delete a row when it expires but it will cause an extra burden on my application. So is it possible to have SQL responsible for deleting a row at a certain time and date?
Also, I have another question:
when I asign a PK Identity to a certain column is there a way I can enforce consecutive order of PK values? For example if I delete a row and the PK value was 5 it will reoder the whole table so all PK values are in consecutive order:
PK-----------Item----------price
1------------XYZ1----------$$$$
2------------XYZ2----------$$$$
3------------XYZ3----------$$$$
when I delete PK 2 this is what happens
PK-----------Item----------price
1------------XYZ1----------$$$$
3------------XYZ3----------$$$$
the PKs are not in consecutive order
What I want is this to happen: when PK 2 is deleted I need it to show as follows
PK-----------Item----------price
1------------XYZ1----------$$$$
2------------XYZ3----------$$$$
The PKs stay in consecutive order.
See how the PK are still in consecutive order?

hi. i'm trying to make a report in asp that sums up a whole bunch of statistics. the report is quite lengthy and takes about 2 minutes to load. i thought i would solve that problem by making a table to dump the statistics into instead of calculating the statistics every time the report is viewed. this way, the page would just read the table with the statistics already put in it. these statistics would be updated every day or two so i don't need anything up to the minute.however, i have run into a small problem which is actually updating the information in the table. my new table is called OfficeReport and it looks like this:UserID Stat1 Stat2 Stat3 ...... Stat3223 0 0 0 056 0 0 0 072 0 0 0 0this is a query for one of the statistics i am currently using:SELECT DefendantCase.UserID, COUNT(DefendantCase.UserID) AS CountOfUserID FROM DefendantCase LEFT JOIN UserDescription ON DefendantCase.UserID=UserDescription.UserID WHERE UserDescription.Status=1 AND UserDescription.UserType=1GROUP BY DefendantCase.UserIDif i run this query, this is what i get:UserID CountOfUserID54 2160 1052 294 427 22how can i modify this query so its output updates the same UserID column in the OfficeReport table? Thanks!

SELECTDATEDIFF(dd,'2007-04-01 00:00:00.000',GetDate()) AS 'Days Left'
This works fine, however: After the 1st April 2007 I want to start counting down the days till 1st April 2008 - and so on and so forth.
How can I do this? Hopefully you understand my question - if not, ask me any questions needed!
