Retrieving Multiple Rows For A Cursor Item
Sep 28, 2000
Hi, can someone plz give me an idea of how to proceed with this...
I've got a server side cursor that retrieves a list of customers from a sql server table which match a specific criteria (those who have had orders in the yr 2000)
For each customer, I need to retrieve a list of 5 top items purchased along with dollars spent on each item by that customer.
I've tried to do this in a loop that uses a counter but probably my syntax was off and I'm not sure that this is better than a correlated join? Can someone show me a temlate of the appropriate syntax to use for this operation
I appreciate suggestions, thanks again.

OK here's my question. I want to retrieve from my database employee table all those employees with the name eg. Smith and display them in a list. Can anyone give me any pointers please. I'm using VB 2005 Express Edition. So far this is what I have but it only seems to return 1 row when I know there are more than one entries with the name I am inputting
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim searchString As String
searchString = Me.SearchStringBox.Text
Try
Dim filter As String
filter = "LastName LIKE '" & searchString & "'"
Dim search() As System.Data.DataRow
search = myCDDataSEt.ClientData.Select(filter)
If search.Length > 0 Then
'no code as yet
Else
MessageBox.Show("The client " & searchString & "is not in the database")
End If
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
End Sub

I don't understand using a dynamic cursor.
Summary
* The fetch next statement returns multiple rows when using a dynamic cursor on the sys.dm_db_partition_stats.
* As far as I know a fetch-next-statement always returns a single row?
* Using a static cursor works as aspected.
* Works on production OLTP as well as on a local SQL server instance.
Now the Skript to reproduce the whole thing.
create database objects
-- create the partition function
create partition function fnTestPartition01( smallint )
as range right for values ( 1, 2, 3, 4, 5, 6, 7, 8 , 9, 10 ) ;
[Code]....
Why does the fetch statement return more than 1 row? It returns the whole result of the select-statement. When using a STATIC cursors instead I get the first row of the cursor as I would expect. Selecting a "normal" user table using a dynamic cursor I get the first row only, again as expected.

I am trying to create a report using Reporting Services.
My problem right now is that the way the table is constructed, I am trying to pull 3 seperate values i.e. One is the number of Hours, One is the type of work, and the 3rd is the Grade, out of one column and place them in 3 seperate columns in the report.
I can currently get one value but how to get the information I need to be able to use in my reports.
So far what I've been working with SQL Reporting Services 2005 I love it and have made several reports, but this one has got me stumped.
Any help would be appreciated.
Thanks.
I might not have made my problem quite clear enough. My table has one column labeled value. The value in that table is linked through an ID field to another table where the ID's are broken down to one ID =Number of Hours, One ID = Grade and One ID= type of work.
What I'm trying to do is when using these ID's and seperate the value related to those ID's into 3 seperate columns in a query for using in Reporting Services to create the report
As you can see, I'm attempting to change the name of the same column 3 times to reflect the correct information and then link them all to the person, where one person might have several entries in the other fields.
As you can see I can change the names individually in queries and pull the information seperately, it's when roll them altogether is where I'm running into my problem
Thanks for the suggestions that were made, I apoligize for not making the problem clearer.
Here is a copy of what I'm attempting to accomplish. I didn't have it with me last night when posting.
--Pulls the Service Opportunity
SELECT cs.value AS "Service Opportunity"
FROM Cstudent cs
INNER JOIN cattribute ca ON ca.attributeid = cs.attributeid
WHERE ca.name = 'Service Opportunity'
--Pulls the Number of Hours
SELECT cs.value AS 'Number of Hours'
FROM Cstudent cs
INNER JOIN cattribute ca ON ca.attributeid =cs.attributeid
WHERE ca.name ='Num of Hours'
--Pulls the Person Grade Level
SELECT cs.value AS 'Grade'
FROM Cstudent cs
INNER JOIN cattribute ca ON ca.attributeid =cs.attributeid
WHERE ca.name ='Grade'
--Pulls the Person Number, First and Last Name and Grade Level
SELECT s.personnumber, s.lastname, s.firstname, cs.value as "Grade"
FROM student s
INNER JOIN cperson cs ON cs.personid = s.personid
INNER JOIN cattribute ca ON ca.attributeid = cs.attributeid
WHERE cs.value =(SELECT cs.value AS 'Grade'
WHERE ca.attributeid = cs.attributeid AND ca.name='Grade')

I have the following sql:
SELECT DISTINCT patient.patientID, patientFirstName, patientLastName, patientDOB, patientGender, completed_date
FROM patient
LEFT JOIN patient_record ON patient_record.patientID = patient.patientID
WHERE (sub_categoryID = 4 OR patient_record.allocated = 4)
AND (patient_status = 1 OR patient_status = 2 OR patient_status = 5)
GROUP BY patient.patientID, patientFirstName, patientLastName, patientDOB, patientGender, completed_date
This brings up duplicate records, my aim is to bring distinct records, now if I take out the other returned fields after patientID
and using the following sql:
SELECT DISTINCT patient.patientID
FROM patient
LEFT JOIN patient_record ON patient_record.patientID = patient.patientID
WHERE (sub_categoryID = 4 OR patient_record.allocated = 4)
AND (patient_status = 1 OR patient_status = 2 OR patient_status = 5)
GROUP BY patient.patientID
This bring up distinct results, but I need to retrieve the other fields from the database i.e. patientFirstName and patientLastName
Please can you help.

My co worker designed a database where retail items can be placed in multiple catagories. This seems odd to me..... In general, Isnt it more normal than not to be only one catarory for each item? For example, lets say I was selling a bowling ball with a picture of Mickey Mouse on it. I can then find this item in the "Mickey Mouse" catagory or in the "bowling ball" catagory but in the database the bowling ball has only one catagoryID. When I worked for a multi-million dollar corporate retail store , an item was listed once in only one catagroy. But i am sure items can be viewed
I know there isnt a single rule, I am just looking for a solution. How should the database sturucture be built with this in mind starting out with what is listed below???? Mabey an attributes table?
Items
ItemID ItemName CatagoryID
Catagories
CatagoryID CatagoryName

Hello,Currently we are in the process of implementing a sql server database where couple tables will have millions of rows ( about 98 millions and will grow) and a web site that will retrieve and sort the data ( read only). How asp.net gridview and sqldatareader act situation like that? Will it be a very slow response? Is there any alternative? Is there any example on the net?
Assuming tables are well tuned and well indexed.
Thank you in advance.

I wonder if you can help...
I have a simple setup: 2 tables and a joining table, and want to retrieve a data set showing every possible combination of table A and table B together with whether that combination actually exists in the joining table or not.
My tables:
channels
======
channel_id
channel_name
items
====
item_id
item_name
channels_items (joining table)
===========
channel_id
item_id
created
An example of the dataset I want (assuming 2 items and 2 channels, with itemA not being in channelB):
item_id item_name channel_id channel_name exists
======= ========= ========== ============ ======
1 ItemA 1 ChannelA True
2 ItemB 1 ChannelA True
1 ItemA 2 ChannelB False
2 ItemB 2 ChannelB True
I'm completely stuck on how to achieve this. Any guidance would be very much appreciated.

Message:
Hi,
Suppose i execute a query,
Select * from emp,
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
so that i can get rows from 10 to 30.
Has any1 done this, plz let me know.
Cheers,
Prashant.

The Above is my database, I need help in retrieving the X_Co and the Y_Co using values of rcv_A, rcv_B and rcv_C to compare with the Mean_A, Mean_B, Mean_C. The values of rcv_A, rcv_B and rcv_C are instances of values that are not exact of the mean columns , and we want is to compare it against our database and retrieve the row that is the closest to the rcv_A, rcv_B and rcv_C.
Here is an example of what i need. Let's say my rcv_A = 71, rcv_B = 73 and rcv_C = 70.8, so the row with mean value closest would be row 1, followed by row 2, then row 3.
So the result i hope to retrieve is in order of the closest value and i only need the X_Co and Y_Co.
This is what i want
X_Co Y_Co

I have multiple SQL 2000 servers that hold data which I retrieve using a single SQL stored procedure. Unfortunately, I don't know how to retrieve this data asychronously (in parallel).
For example, I retrieve data from two linked servers using the following:
select * into #temp from openquery(SomeLinkedServer,'exec BigQueryHere')
select * into #temp2 from openquery(OtherLinkedServer,'exec BigQueryThere')
.
.
lots of manipulation of the temporary tables to get what I want, etc.
.
.
The problem I have with this is that there is no reason why the first query should have to finish before the second query begins (serially) because these are on separate servers. Is there a way to execute these so that they run at the same time?

Hi - I'm new to SSRS/SQL and have a situation I can't figure out. I've tried a number of things, but I'm not sure the best way to return a calculated column based on the structure of my tables.
I have a primary Detail table that tracks product testing results. The Detail records need to be calculated against a "Year" table that contains a set of values by year. This table contains a single record for each year. There isn't a direct key that joins these two tables.
The Detail table looks like:
Record ID: 9999
PO Number: 12345
Date: 12/1/2007
Test Result: 1.52
The Year table looks like:
Record ID: 1
Start Date: 10/6/2007
End Date: 6/14/2008
LowVal1: 1.0
HighVal1: 1.49
Incentive1: .05
LowVal2: 1.50
HighVal2: 1.59
Incentive2: .06
and so on...
The Detail records need to find the correct Year record based on the Detail date, find the correct value within the LowVal - HighVal range based on the Test Result value, and then multiply the Test Result by the correct Incentive value and return that value.
I was able to find the correct LowVal-HighVal range using an Expression in the report column. Now that I need multiple years, I can't figure out the best way to configure the query.
Any suggestions would be appreciated. Thanks in advance!

Hi,
Here's my problem. I have 2 tasks defined in my Control Flow tab:
EXECUTE SQL--------->EXECUTE DTS 2000 PACKAGE
When I attempt to run it, by right-clicking the EXECUTE SQL task, and selecting "Execute Task", it only runs the EXECUTE SQL part (successfully), and does not "kick off" the EXECUTE DTS 2000 PACKAGE, after it is done running (even though it completes successfully, as shown by the green box).
Yes, they are connected by a dark green arrow, as indicated in my diagram above.
Why is this?? Am I missing something here? Need help.

Hello,
I have a survey (30 questions) application in a SQL server db. The application uses several relational tables. The results are arranged so that each answer is on a seperate row:
user1 answer1user1 answer2user1 answer3user2 answer1user2 answer2user2 answer3
For statistical analysis I need to transfer the results to an Excel spreadsheet (for later use in SPSS). In the spreadsheet I need the results to appear so that each user will be on a single row with all of that user's answers on that single row (A column for each answer):
user1 answer1 answer2 answer3user2 answer1 answer2 answer3
How can this be done? How can all answers of a user appear on a single row
