Hi,
I am using sqldatasource. I would like to do certain computation and update the record based on the click of the update button. Also, I would like to ensure that the update has been successful with a messagebox stating that the update has been successful.
Any help on this will be highly appreciated.
Thanks

What is the easiest way to obtain number of records in SQLDataSource (using select statement)/GridView. All that I've found in forums seems to be very difficult for such trivial task... Thank you!
View 4 Replies View RelatedIs there a way to limit the records that SqlDataSource returns with sql query, say records 10 to 20 only?

Hi -- I'm starting an ASP.NET 2.0 application which contains a page with a checkbox and gridview control on it. In its default state the gridview displays all the records from a table pulled from a SQL Server database (via a SqlDataSource object). When the user checks the checkbox, I want the gridview to display only the records where one of the columns is not null. But I've been unable to construct the WHERE clause of the SQLDataSource object correctly. I see that I can hard-code the SqlDataSource object so that the column to be filtered is always NULL or always NOT NULL. But I want this filtering to be more dynamic such that the decision to show all or non-null records happens at run-time. Should I be using two SqlDataSource objects -- one for the NOT NULL condition and one for the "all records" condition? Then when the user checks the checkbox, the gridview would be configured to point to the appropriate SqlDataSource object. (???) Seems like a bit of overhead with that approach. I'm hoping there's a more elegant way to get this done. Please let me know if you need more information. Thanks in advance. Bill

I'm using SqlDataSource control.
Is there a way to know how many records a query has returned?
Hi, and thanks in advance.
I have VWD 2005 Express and SQL 2005 Express running.
I have a SqlDastasource wired to the stored procedure. When I only include one Control parameter I get results from my Stored procedure, when I inclube both Control Parameters I get no results. I manually remove the second control parameter from the sqldatasource by deleting...
<asp:ControlParameter ControlID="ddlSClosed" DefaultValue="" Name="SClosed" PropertyName="SelectedValue" Type="String" />
I have one Radio Group and one dropdownlist box that supplies the parameters. The dropdownlist parameter is Null or "" when the page is first loaded.

HI,
I have been trying to solve the locking problem from past couple of days. Please help mee!!
Scenario:
--------------
I have a SSIS package in which 2 data flow tasks. 1st data flow task deletes records from a 5 tables and the 2nd data flow task should insert records into 1 of the five tables after the success of 1st data flow task. This scenario runs in Transacation.
The above scenrio in the 2nd data flow task hangs in runtime. It does not complete. with sp_who2 command i could see that there is an intent share lock(LK_M_IS) on the table and the status is SUSPENDED.
I dont know how to come out of this locking. Please help.

I have a table with about half a million records, each representing a patient in my county.
Each record has a field (RRank) which basically sorts the patients as to how "unwell" they are according to a previously-applied algorithm. The most unwell patient has an RRank of 1, the next-most unwell has RRank=2 etc.
I have just deleted several hundred records (which relate to patients now deceased) from the table, thereby leaving gaps in the RRank sequence. I want to renumber the remaining recs to get rid of the gaps.
I can see what I want to accomplish by using ROW_NUMBER, thus:
SELECT ROW_NUMBER() Over (ORDER BY RRank) as RecNumber, RRank
FROM RPL
ORDER BY RRank
I see the numbers in the RecNumber column falling behind the RRank as I scan down the results
My question is: How to convert this into an UPDATE statement? I had hoped that I could do something like:
UPDATE RISC_PatientList_TEMP
SET RRank = ROW_NUMBER() Over (ORDER BY RRank);
but the system informs that window functions will only work on SELECT (which UPDATE isn't) or ORDER BY (which I can't legally add).
I need a little help here..I want to transfer ONLY new records AND update any modified recordsfrom Oracle into SQL Server using DTS.

Perhaps youcan email me the Demo Package as well.b) so far, what I did was,- I have datemodified field in my Oracle table so that I can comparewith datelastrun of my DTS package to get new records- records in Oracle having datemodified >Max(datelastrun), and transferto SQL Server table.Now, I am stuck as to where should I proceed - how can I transfer theserecords?Hope u can give me some lights.

View 2 Replies View RelatedI 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?
Thanks in advance.

Hi,
I have to search the records after the records populated.
I mean to say, i have displayed records in report, if i enter some strings in the textbox and clicked find, then it will highlight the particular records, instead of highlighting the values, is it possible to display only those particular records.
For example, say i have 50 records in a page,i entered some strings in the textbox and clicked find, then it will highlight the particular 5 records one by one which match the criteria i have entered in the texbox, instead of that i have to display only those 5 records.
Please tell me how to implement in this report,
Thanks and Regards

Ok, I'm really new at this, but I am looking for a way to automatically insert new records into tables. I have one primary table with a primary key id that is automatically generated on insert and 3 other tables that have foreign keys pointing to the primary key. Is there a way to automatically create new records in the foreign tables that will have the new id? Would this be a job for a trigger, stored procedure? I admit I haven't studied up on those yet--I am learning things as I need them. Thanks.

I am trying to write a query that will retrieve all students of a particular class and also any rows in HomeworkLogLine if they exist (but return null if there is no row). I thought this should be a relatively simple LEFT join but I've tried every possible combination of joins but it's not working.
SELECT
Student.StudentSurname + ', ' + Student.StudentForename AS Fullname,
HomeworkLogLine.HomeworkLogLineTimestamp,
HomeworkLog.HomeworkLogDescription,
ROW_NUMBER() OVER (PARTITION BY HomeworkLogLine.HomeworkLogLineStudentID ORDER BY
[Code] ...
It's only returning two rows (the students where they have a row in the HomeworkLogLine table).
I'm looking for a way of taking a query which returns a set of date time fields (probable maximum of 20 rows) and looping through each value to see if it exists in a separate table.
E.g.
Query 1
Select ID, Person, ProposedEvent, DayField, TimeField
from MyOptions
where person = 'me'
Table
Select Person, ExistingEvent, DayField, TimeField
from MyTimetable
where person ='me'
Loop through Query 1 and if it finds ANY matching Dayfield AND Timefield in Query/Table 2, return the ProposedEvent (just as a message, the loop could stop there), if no match a message saying all is fine can proceed to process form blah blah.
I'm essentially wanting somebody to select a bunch of events in a form, query 1 then finds all the days and times those events happen and check that none of them exist in the MyTimetable table.
I'm at a bit of a loss here. My T-SQL skills are not up to the task at hand here :(
I've got company records in one table and SIC codes that correlate to the companies linked by the company ID. So, I can run the query, but the output I get is multiple records for each company, because some companies have multiple SIC codes associated with them.
I understand how to get only one record, but what I want to do is create a result set that has all the SIC codes associated with one company. Possibly in a comma seperated list, that would count as one field.
Anyone have any idea how to bring back all the SIC codes for one company as one variable (or multiple variables, but in one record)?
Thank you very much for any help,

I cannot figure out how to write a sql statement to display the multiple records of multiple records. I know that doesn't make much sense so let me explain:
This problem involves two tables. They both reference (FK) data in a third table (tblDepartment).
Here are the fields and some test data in each of the two important tables:
=============
tblDepartment =============================
departmentIDuserID
-----------------------------
1user1
2user1
1user2
2user3
3user3
3user4
===========
tblRequest ========================================
requestIDdepartmentIDuserID
----------------------------------------
11user1
21user2
32user3
43user3
53user4
62user1
What I am trying to do is display all requests associated with the multiple departments of "user1". In the above example, I would want to see (after a select statement):
requestIDdepartmentIDuserID
----------------------------------------
11user1
21user2
32user3
52user1
We don't see the requests of user3 or user4 when the given request's departmentID is not a department associated with user1.
Hopefully someone out there understands this. I've never had to write a select statement like this before, so I'm having trouble wrapping my mind around it. Thanks for any help!
Hi,
I have one table which holds an ID, a name, and a parentID (which can either the same as the main ID or it's one of the other ID in that tbl)
At the moment I do a select on the records whos main ID is the same as the ParentID. This gives me an initial list of records who are the "Main" parent records (i.e they are not the child of any other record..
so far so good.
However, what I need to do is for each record work out if they themselves have any Child records. (only some have).
so at the mo I end up with a results set as this:
1 Boats
2 Jumpers
3 Trousers
4 Ships
What I want to end up is something like
1 Boats True
2 Jumpers False
3 Trousers True
4 Ships True
Where the true or false is if the record has any child records..
Any ideas?

I have always (in 1.1) used server side connections and adapters to bind my Sql datasets to any control needed. Now that im learning 2.0 im finding it difficult to understand using control on the page to bind my data. Can someone explain the benefits of using this data source? Ideally i would like to keep my data access layer separate from my presentation layer but i'd really like to understand why this method seems so popular.
