Retrieving The First N Records From A SQL Query In VS 2005
Apr 6, 2006
Hi,
first off, I'm a TOTAL novice at this stuff, I'm just currently blundering my way through a complex site to learn stuff.
I'm trying to call the newest addition to a SQL database into a webpage, in this case, it'll be 'newest user', one result only. I've done several other data retrival sections using a datatable, but the guy who was helping me though it is unavailable at the moment and I get the feeling I've jumped into the deepend slightly.
Could anyone give me an example of how retrieving the First N Records from SQL should look in VS? Does it need to be in a data table or can it go in a label?
Sorry if this is somewhat vague, but as I said, I've really only been using VS for a week!
Hi every body, I am making a program which is currently dealing with thousands of records. What I want is to have a button in the front END which make me able to fetch only first 100 record.If the desired record doesn't come with in first 100 record I press this button another time to fetch next 100 records i.e. from 101 to 199. How can it be possible in SQL Server stored procedure.

I'm trying to read from a table and return only the unique records from a table. The table has 3 columns, ID - Autoinc Amount - decimal 6,2 Name - varchar(10)
I am wanting to retreive only records 3 & 6 (values 0.05 0.06) as they are the only ones where amount is unique i.e. only 1 entry in the table.
I put the following sql statement together which achieves this but it it only returns the amount value select Count(amount),amount from bids group by amount having count(amount)<2 order by amount
So I then expanded it to read select Count(amount),amount,name from bids group by amount,name having count(amount)<2 order by amount not sure where i'm going wrong but the results returned were 0.03 0.03 0.05 0.06 0.07 0.07
I want to create sql for retrieving 10 records per time but need to know the total result matches. And I have previous and next button for retrieving previous or next 10 records.
I need help with this. When I run the below script (only select) it retrives around 130K records and gives me the output within 2 mins. Whenever I try to put the same output in a temp or permanent table it takes hours. Any Idea why?

CREATE TABLE [dbo].[tblSubscription]( [SubscriptionID] [int] IDENTITY(1000000,1) NOT NULL, [SubscriberID] [int] NOT NULL, [Status] [int] NOT NULL, [JournalID] [int] NOT NULL,
CREATE TABLE [dbo].[tblTransaction]( [TransactionID] [bigint] IDENTITY(100000000,1) NOT NULL, [TransactionTypeID] [int] NOT NULL, [SubscriptionID] [int] NOT NULL, [Created] [datetime] NOT NULL,
CREATE TABLE [dbo].[tblMailing]( [MialingID] [bigint] IDENTITY(1000000000,1) NOT NULL, [SubscriptionID] [int] NOT NULL, [MailTypeID] [int] NOT NULL, [MailDate] [datetime] NOT NULL
So for each subscription there can be 1 or more transactions and 0 or more mailings, and the mailings are not necassarily related to the transactions. What I am having difficulty doing is this:
I wish to select tblMailing.MailingID, tblMailing.MailDate, tblMailing.SubscriptionID (or tblSubscription.SubscriptionID), tblSubscription.SubscriberID, tblSubscription.Status, tblTransaction.TransactionID, tblTransaction.Created, but I only wish to retrieve rows from the transaction table where tblTransaction.Created is the latest dated transaction for that subscription. I.E. (maybe this makes more sense..:) I wish to select all rows from tblMailing along with each mailing's relevent subscription details, including details of the LATEST TRANSACTION for each of those subscriptions.
I am currently working along the lines of MAX(tblTransaction.Created) and possibly GROUP BY in a subquery, but cannot quite figure out the logic.
if I create an index for a table with some records, do you think I can retrieve records in a giving range? for example, the 5th to 10th records?Possible? How can I do it?When we insert data at the table, would the index in sequential order? How would the index be created for new inserted records?I'm using SQL 2005 Express, not SQL 2000.
Hi all,I have a table with this structure:Customer ID | Transaction date | Transaction type1 | 1/2/2008 | F1 | 1/4/2007 | M1 | 1/2/2008 | R2 | 1//5/2007 | M2 | 1/6/2007 | RFor each customer ID, I need to retrive only the records with the mostrecent transaction date, and I did:Customer ID | Transaction date | Transaction type1 | 1/2/2008 | F1 | 1/2/2008 | R2 | 1/6/2007 | RThe problem is, each customer can make more than one transaction inthe same day (see above). In these cases, I need to retrieve only onerecord per customer, based on the importance of the transaction: F ismore "important" than R which is more "important" than M. So, in theexample above, I would only retrieve transaction F for customer 1 anddisregard transaction R: they were made on the same date, but I ammore interested in F than in R.Do you have any suggestions on how I could achieve this in SQL?I use Microsoft SQL server 2005.Thank you for your help!

Hello. I'm having troubles with a query that (should) return all therecords between two dates. The date field is a datetime type. The db isSQL Server 2000. When I try thisSELECT RESERVES.RES_ID, PAYMENTS_RECEIVED.PYR_ID,PAYMENTS_RECEIVED.PYR_VALUE, PAYMENTS_RECEIVED.PYR_DATE,CUSTOMERS.CUS_NAMEFROM RESERVES LEFT OUTER JOINPAYMENTS_RECEIVED ON RESERVES.RES_ID =PAYMENTS_RECEIVED.RES_ID LEFT OUTER JOINCUSTOMERS ON RESERVES.CUS_ID = CUSTOMERS.CUS_IDWHERE (PAYMENTS_RECEIVED.PYR_DATE >= '2006-03-20 00:00:00') AND(PAYMENTS_RECEIVED.PYR_DATE < '2006-03-27 00:00:00')on a "query builder" in visual studio, I get the results that I want.But when I use exactly the same query on an asp 3 vbscript script, Iget no results (an empty selection).I've done everything imaginable. I wrote the date as iso, ansi, britishformat using convert(,103) (that's how users will enter the dates),i've used cast('20060327' as datetime), etc. But I can't still get itto work. Other querys from the asp pages work ok. Any ideas?thanks a lot in advance

I am trying to retrieve the user names of all users within a database. The problem is, that I have only created a login within SQL 7.0 for the NT group that the users belong to.
As such, when I try to query the syslogins table I only get the NT group.
Is there any way of retrieving the users that belong to this NT group.
Any help or suggestions on this would be greatly appreciated.
The primary key of my database (SQL server 2005) table is a uniqueidentifier.
I am using the following code to insert a row into my table:
myCommand.CommandText = sqlEvent.ToString(); //add the sql query to the command myCommand.Connection = this.dbConnection; //add the database connection to the command myCommand.ExecuteNonQuery(); //execute the insert query
I need to retrieve the GUID that is automatically generated when the insert command is executed.
Can someone help me? How do I get the GUID that is automatically generated? I have tried lots of things like using
string _id = (string)myCommand.ExecuteScalar();
and I am still stuck. I will really appreciate it if someone can refer me to some code sample.
I get 100 rows of result, i want to write a sql query similar to the one available in MySql database where in i can specify the starting row and number of rows of records i want,
something like,
select * from emp LIMIT 10,20
I want all the records from the 10th row to the 20th row.
This would be helpful for me to do paging in the front end , where is i can navigate to the next previous buttons and fetch the corresponding records.
I want to do something like in google, previous next screens.
So I am trying to limit the number of rows fetched from a query.
somethin like,
select * from emp where startRowNum=10 and NoOfRecords = 20
( select min(cast(f.valuestr as float)) from bvfindings f where f.ObjectName = 'Hematocrit' and f.sessionid = s.sessionid and f.ValueTime > s.open_time)
the above returns me the 10.9
i modified the query
select min(cast(f.valuestr as float)), f.valuetime from bvfindings f where f.ObjectName = 'Hb'
I have a query similar to the following. The intent of this query is to retrieve the top 6 records meeting the specified criteria (LOGTYPENAME = 'Process Status Start' OR LOGTYPENAME = 'Process Status End' ) based on most recent dates. Please keep in mind that I expect to return up to 6 records for each unique LogProcessName. This could be thousands of different LogProcessNames with up to 6 records for each.
1) The table I am executing against currently is very large in size and thus takes a long time to execute against. It would seem there must be a more efficient query to get the results I am looking for? 2) CTE doesn't work on SQL 2000. I need a query that does. 3) I cannot modify the database itself in the process.
;WITH cte AS ( SELECT [LogProcessName], [LogBody], [LogDate], [LogGUID], row_number() OVER(PARTITION BY [LogProcessName] ORDER BY [LogDate] DESC) AS RN FROM [LOGTABLE] WHERE [LogTypeGUID] IN ( SELECT LogTypeGUID FROM LOGTYPE WHERE LogTypeName = 'Process Status Start' OR LogTypeName = 'Process Status End' ) ) SELECT * FROM cte WHERE RN = 1 OR RN = 2 OR RN = 3 OR RN = 4 OR RN = 5 OR RN = 6 ORDER BY [LogProcessName] DESC, [LogDate] DESC
Does anybody else have any idea that would yield the results that I am looking for and take into account items 1-3 above?
Hi There, Can I store flash files in the database. I have a table with one of the columns as varbinary datatype. Previously, I was saving images (as filebytes) into this column. But now I need to implement something to store the flash file. So, is it possible to store flash files in the database and retrieve them and display them in an asp.net page? Thanks a lot for your suggestion!!
Hi every one, I have a database table and currently users may retrieve records for a specified date range by providing the start and end dates and then records between those dates provided are retrieved. For example if users wanted to view all records entered in april, they would have to select 04/01/2007 as the start date and then 04/30/2007 as the end date. The records for april would then be displayed in a gridview. How can configure my sql query such that instead the user selectes a month from a dropdownlist of 12 months. I would love a user to just select the desired month from a list instead of selecting start and end dates. Eg if they are intrested in a report for june, then they should just select june from the list instead of specifying the start and stop dates. HOW can i achieve this.
Hi, I got a problem. I installed Microsoft SQL Server Management Studio Express 2005 version. And I created a Compact database. I created an connection in SSMSE to connect the database and opened a query form. then, i run the following sql:
Select * from Table1
It returned 3 records to me. After that, I used program to insert record into this table. Then i ran this sql again, it still show me 3 records. I closed the query form, and re-created a new query form, then run the sql, it returned 4 records to me.
Why? It's very strange and difficult to operate, right? Is there anyone know how to make the SSMSE to return whole records without any close query form and re-create query form operation?
Hey Guys, I have a contacts table that contains ID, First Name, Last Name, and Phone Number, Date Entered, Changed. Every time, the data is modified and saved, it will insert a new record in the table. So, Ill create a new record for a contact named Ryan, and then come back a day later and update the last name and phone number. So theSQL table would look like...1 Ryan Scott 818-550-0000 05/08/2008 Null2 Ryan Peters 000-000-0000 05/09/2008 Null How do I write a sql query that will run an update after the insert of the second record to fill in the Changed field with the data that changed?So I want to have record 2, end up looking like this... 2 Ryan Peters 000-000-0000 05/09/2008 LastName,PhoneNumberAny ideas?

I want to have all the ethnicities from the Ethnicgroup table to be displayed in a particular area which is in where clause as aggcourseid
The problem is that even when I have a left join on the EthnicGroup table it will not return all the ethnicities but will only return those who were existing in that particular aggcourseid.
i.e. If there is no African student in E2, it will not show up in the result whereas I want to display all the ethnicities and if there is no record for aggcourseid, it should show up as 0/NULL for that ethnicity.
I have tried all sorts of joins but the problem is whenever I put in the aggcourseid in where clause, it wont bring all the records

This above query returns all requests that meets atleast one criteria. How do i edit my query such that i get requests that meet both criteria and the result set looks like below

Create a new table named frequent travelers (FreqTrav). It will only store passengers who have taken more than 2 trips with the company. It will record the passenger name, passenger number, address, phone number, total trips and total fare paid. Show your CREATE TABLE query and INSERT query. Please insert the records using subquery (i.e. insert from a SELECT query).
CREATE TABLE FreqTrav ( PASSENGERNUM INT(20) CHECK (PASSENGERNUM IN
[code]...
but It's not working for me since I tried inserting a passengernum who did't travel more than two times and it was inserted.Is there any way I can answer without using check constraint.
