Select Last 20 Records By Date Then Sum Lowest 10 Scores???
Jan 21, 2004
I have a table and am usuing ASP to query the database, the connection is to a MS Access table at the moment but am working to convert to SQL Server.
Question:
I need to select the last 20 records, by a date field, then from those 20 records select the 10 lowest scores.
Example is a member logs on an that member has say 80 total records in the table. Then I need to select the last 20 records entered by the date field then select the lowest 10 scores out of those 20.
I am new to more compex SQL Statements any help would be mostly appreciated!
table = HC_ID
date field = date
member_id = member
score = ScoreHC

I am trying to interpret some of the results I observe when trying to match similar records using a fuzzy lookup transform, but it's not entirely clear how the overall row similarity score is calculated. In particular, sometimes rows with lower individual column similarity scores will achieve a higher similarity and confidence score than a matching row with higher individual column scores.
The transform is configured with 6 text fields set to fuzzy mapping and a minimum similarity of 0, and 3 additional numeric fields with an exact mapping. It is set to return a maximum of 2 matches per lookup and to do an exhaustive search of the reference table.
For example, from the following matching pair of records Match 1 is picked over Match 2 even though it's individual scores are lower.
Match 1 Match 2
----------------- -----------------
_similarity_author 1.0 1.0
_similarity_title 0.85344648 1.0
_similarity_headline 0.0125 0.0125
_similarity_summary 0.0125 0.0125
_similarity_picture 1.0 1.0
_similarity_caption 1.0 1.0
_similarity 7.8429267E-2 7.3196657E-2
_confidence 0.55728668 0.44271332
In another case both matching records have *identical* scores for every mapped column and yet their similarity and confidence scores are different.
Clearly there are other factors involved in calculating the overall row score. Anybody know what these are?

I'm using sql express 2005. I need help with buliding a view.
I'm trying to join two tables and then, if duplicate ID's exist, retrieve the row with the lowest value in a specific column.
For instance:
TableHousehold:
ID Name Status
001 The Smiths A
002 The Jones A
003 The Adams A
004 The Grants A
TableResidents
Pk HouseholdID ResidentID Name Gender
1 001 1 Mary Smith F
2 001 2 Jason Smith M
3 001 3 Rachel Smith F
4 002 1 Mike Jones M
5 002 2 Sara Jones F
6 003 2 Erik Adams M
The resident ID is auto increment and assigned by the server. It is possible for resident 1 for each household to have been deleted. It is also possible that a household does not contain any residents. Therefore, I wish to join these tables and return this:
ID HouseHoldName Status ResidentName Gender
001 The Smiths A Mary Smith F
002 The Jones A Mike Jones M
003 The Adams A Erik Adams M
004 The Grants A null null
There are other columns in both tables that I will want to join, but for simplicity, the above example illustrates my need.
I was able to accomplish this by creating two views. But Id like to try and do this in one.

I have a select query that looks like this
Select table1.id, table1.original_date,
(select ..from ..) as Date1,
(select ..from..) as Date2
from table1
Date 1 and Date 2 are both complex subqueries that retrieve a date from other tables. I would like another column displaying the oldest date between date1 and date2. Can anyone help?

I have hierarchical data such as:
Id Level ParentId
1 0 1
2 1 1
3 2 2
4 0 4
5 1 4
6 0 6
7 1 6
8 2 7
9 3 8
10 4 9
11 0 11
As you can see even the parent element has parentId(in this case id = parentid)
How can I select the lowest level data in the hierarchy and get this result:
Id Level ParentId
3 2 2
5 1 4
10 4 9
11 0 11

I have a table with a column of type date. I want to select all records where the date column = today. I tried
Select * from myTable where DateSent = GetDate()
but it returns no records.
Do I really have to use this slow method?
select datesent from Messages where convert(varchar,DateSent,103) = CONVERT(varchar, GetDate(), 103)

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.

etc
What I need to do is return a students details followed by their top 10 subjects in ascending order.
Student 1's results would look like this...

I have surveys that I need to add weights to and was wondering if there was a way to convert the contents of a column.
select empid, ans_for_ql,
(if ans_for_ql = A then 0, B then 3, C then 5) as weightscore,
ans_for_q2,
(if ans_for_q2 = A then 8, B then 4, C then 2, D then 1, E then 0) as weightscore
Here is what the table looks like:
empid | Ans_for_Q1 | Ans_for_Q2
1001 A C
1002 B E
And these are the possible answers and what they need to be converted to:
Weights for answers to Question1
Q1_A = 0
Q1_B = 3
Q1_C = 5
Weights for answers to Question2
Q2_A = 8
Q2_B = 4
Q2_C = 2
Q2_D = 1
Q2_E = 0

I am stumped on a set-based approach for this one.
A cursor approach is straightforward enough, but i want to avoid that.
Here's my table:
create table StudentScores
(
id int primary key identity(1,1),
student_id int not null,
score int not null
)
with some sample data:
insert into StudentScores (student_id, score)
select 1, 10 union all
select 1, 29 union all
select 1, 50 union all
select 1, 53 union all
select 1, 45 union all
select 1, 10 union all
select 1, 29 union all
select 1, 50 union all
select 1, 53 union all
select 1, 45 union all
select 1, 88 union all
select 2, 23 union all
select 2, 54 union all
select 2, 55 union all
select 2, 34 union all
select 2, 56 union all
select 2, 78 union all
select 2, 23 union all
select 2, 54 union all
select 2, 55 union all
select 2, 34 union all
select 2, 56 union all
select 2, 78 union all
select 2, 23 union all
select 2, 54 union all
select 2, 55 union all
select 2, 34 union all
select 2, 56 union all
select 2, 78 union all
select 2, 98
What I want is, for each student, what is their 90th percentile score?
For a given single student, one possibility would be:
declare @studentid int
set @studentid = 2
select top 1 @studentid as student_id, a.score as [90th percentile score]
from
(
select top 90 percent score from StudentScores
where student_id = @studentid order by score asc
) as a
order by a.score desc
But I want this for all students, and not use a cursor.
Any ideas?
Thanks!

I need to compare the contents of a column.
I have a table with 1 column. Below are the sample contents..
DateInterval
2012-06-01 00:30:00.000
2012-06-01 01:00:00.000
2012-06-01 01:30:00.000
2012-06-01 02:00:00.000
2012-06-01 02:30:00.000
[code]....
as you can see, the records have a 30minutes time interval. i need to create a query to know if there are missing records in the table. so basically the result should be this:
DateInterval
2012-06-01 18:00:00.000
2012-06-01 20:30:00.000
if it is not doable, we can get the nearest record of all missing records like this:
DateInterval
2012-06-01 17:30:00.000
2012-06-01 20:00:00.000
or this:
DateInterval
2012-06-01 18:30:00.000
2012-06-01 21:00:00.000
or this:
DateInterval
2012-06-01 17:30:00.000
2012-06-01 18:30:00.000
2012-06-01 20:00:00.000
2012-06-01 21:00:00.000

My goal is to select values from the same date range for a month on month view to compare values month over month. I've tried using the date trunc function but I'm not sure what the best way to attack this is. My thoughts are I need to somehow select first day of every month + interval 'x days' (but I don't know the syntax).In other words, I want to see

So my data column [EODPosting].[MatchDate] is defined as a DATE column. I am trying to SELECT from my table where [EODPosting].[MatchDate] is today's date.
SELECT*
FROM[dbo].[EODPosting]
WHERE[EODPosting].[MatchDate]=GETDATE()
Is this not working because GETDATE() is like a timestamp format? How can I get this to work to return those rows where [EODPosting].[MatchDate] is equal to today's date?

I have an unusual problem. I am using VB.Net 2003 and sqlexpress using .NET dataset to insert records into an timecards table. After inserting several records I tried a 'Select * from timecards' and the inserted records where not selected. if I 'select * from timecards order by employee' ( or any other field) the inserted records are selected! The table was created by an Access Upsize command.
Any suggestions?

OK, this should be an easy one but my brain isn't quite working right now.
I have a table, we'll call Table1 like so:
ProductID Supplier Cost
12345 A 14.50
12345 B 13.49
12345 C 12.00
43222 A 15.00
43222 B 15.21
43222 C 13.99
12312 B 14.00
15421 A 21.99
15421 C 20.00
And I want to Get the name of the Supplier with the Lowest cost,
I know I can go like:
SELECT ProductID, MIN(Cost) FROM Table1 GROUP BY ProductID
and get the lowest cost, but what would be the most effiecent way to get all three fields returned by the query? I need the ProductID, Supplier and Cost.
Thanks,

Hi, this seems to be an easy question but I can't find a quick answer to it.
I have an asp page that communicates with a database and I want the following example to work...
Insert 5 records into the DB with primary keys 1-5.
Remove record with key number 2.
Now, if I insert a new record I want it to take the smallest available key number (in this case number 2). This will save space in the database and keep the key numbers from increasing forever.
Does auto increment work like this?
If not, how do I do it?
Thanks for any replies!

I have a little problem that I just haven't been able to solve. I don't think it is very difficult but I can't seem to make it work. Here's the scenario:
I have a database with the following values:
Model Make Price
DA1100 GTN$88.00
DA1100 GTN $100.00
DA1000 GBN$110.00
DA668 GTN$100.00
DA880 GTN$200.00
In this case DA1100 is listed twice with 2 different prices. I only want to display the one with the lowest price. So the result I want is:
Model Make Price
DA1100 GTN$88.00
DA1000 GBN$110.00
DA668 GTN$100.00
DA880 GTN$200.00
