Greater/Less Than Query From Within Subsets Of Results
Sep 27, 2005
I think I'm trying to do a simple query on maximum date.
I've got 100 tools that have been used over the past three years.
Some of the tools are used almost every day. Other tools haven't been used for a month, while other tools haven't been used for a year or more.
Ultimately I'm trying to just find the list of tools whose latest date of use was a year ago.
I have a list of tools and a list of times each tool was used.
I think I'm going to have to do a search that for each tool what was the times it was used. That I can do.
What I'm not sure of is how to then pull only the latest date for each tool.
Once I get that I can then do a query off that result to pull the "oldest latest" date of use.

I really appreciate if someone can give solution for this using a query (SQL server,Access,Foxpro) is fine.
Thanks

I have a table that is created based on a heirarch of set criteria and need to number the subsets within. The best way to illustrate what I want to accomplish is through an example.
Rank | Item_1 | Item_2 | Class
---- | ------ | ------ | ------
1 | 1A | 1B | ExactMatch
2 | 1A | 1C | Sub
3 | 1A | 1D | Sub
1 | 2B | 2F | ExactMatch
2 | 2B | 2G | Sub
Is there a way to accomplish this? Any help or suggestions are appreciated.
I apologize for the formatting, but I think you should be able to get the point.
thanks,

Have not found an active general data mining forum yet so asking here.
I'm new to data mining band have been given the task of setting up a data mining system. The problem is that our setup seems pretty non standard and I'm not sure how to use data mining on it or what my expectations should be. The situation is:
We have a large and growing set of strings which we get requests for (> 100,000). The requests have many, mostly nominal (non-numeric), variables associated with them. We can only handle a subset (probably less than 10,000) or the strings at any one time. We want to use data mining to analyze historic requests so we can figure out which strings we are going to handle under a given set of variables. So given that our variable currently have values X1, ..., Xn, what subset should be use given than a large database of historic string requests.
Anyone know what techniques would work well for this kind of problem? This is a quick and dirty kind of project, no special purpose hardware or expensive software on this one. I've been looking at using rapid miner but not sure that it's a great tool in this case.
thanks in advance,
max

Hello!
I'm looking for some ideas about how
to ensure constraints on multiple rows.
Of course one can use stored procedures and/or triggers while inserting.
Other ideas?
The reason for this question is that it could be hard to ensure,
because if lock level is not high enough, you can get duplicates during concurrency,
if lock level is too high, it can result in deadlocks.
Thanks

hi, like, if i need to do delete some items with the id = 10000 then also need to update on the remaining items on the with the same idthen i will need to go through all the records to fetch the items with the same id right? so, is there something that i can use to hold those records so that i can do the delete and update just on those records and don't need to query twice? or is there a way to do that in one go ?thanks in advance!

Hello. I currently have a website that has a table on one webpage. When a record is clicked, the primary key of that record is transfered in the query string to another page and fed into an sql statement. In this case its selecting a project on the first page, and displaying all the scripts for that project on another page. I also have an additional dropdownlist on the second page that i use to filter the scripts by an attribute called 'testdomain'. At present this works to an extent. When i click a project, i am navigated to the scripts page which is empty except for the dropdownlist. i then select a 'testdomain' from the dropdownlist and the page populates with scripts (formview) for the particular test domain. what i would like is for all the scripts to be displayed using the formview in the first instance when the user arrives at the second page. from there, they can then filter the scripts using the dropdownlist.
My current SQL statement is as follows.
SelectCommand="SELECT * FROM [TestScript] WHERE (([ProjectID] = @ProjectID) AND ([TestDomain] = @TestDomain))"
So what is happening is when testdomain = a null value, it does not select any scripts. Is there a way i can achieve the behaivour of the page as i outlined above? Any help would be appreciated.
Thanks,
James.

I have the following 2 Sql queries. They both are rowcounts of the same column but based on different criteria. What I want to do is return the two results side by side in separate columns:
-- Subscriptions since Sept. 24th
SELECT count(*)
FROM SiteMemberTable103 s(nolock)
JOIN clientmembertable25 c(nolock) ON s.memberid = c.memberid
WHERE site_firstjoindate is not null
and c.clientunsubscribe = 0
and c.validemailaddr = 1
and s.unsubscribe = 0
-- Subscriptions in February
SELECT count(*)
FROM SiteMemberTable103 s(nolock)
JOIN clientmembertable25 c(nolock) ON s.memberid = c.memberid
WHERE site_firstjoindate BETWEEN '2006-02-01 00:00:00.000' AND '2006-03-01 00:00:00.000'
AND c.clientunsubscribe = 0
AND c.validemailaddr = 1
AND s.unsubscribe = 0
It seems like a UNION ALL should work but it just returns the results in one column. I tried changing the count by specifying a different column for each but that doesn't work either. I also tried writing it as one query and using alias to differentiate the two tables but that just gives me syntax errors. I suspect there is a more elegant way to do this but I'm at a loss. Any help would be greatly appreciated!

-- The 3rd query uses an incorrect column name in a sub-query and succeeds but rows are incorrectly qualified. This is very DANGEROUS!!!
-- The issue exists is in 2008 R2, 2012 and 2014 and is "By Design"
set nocount on
go
if object_id('tempdb.dbo.#t1') IS NOT NULL drop table #t1
if object_id('tempdb.dbo
[code]....
This succeeds when the invalid column name is a valid column name in the outer query. So in this situation the sub-query would fail when run by itself but succeed with an incorrectly applied filter when run as a sub-query. The danger here is that if a SQL Server user runs DML in a production database with such a sub-query which then the results are likely not the expected results with potentially unintended actions applied against the data. how many SQL Server users have had incorrectly applied DML or incorrect query results and don't even know it....?

For each customer, I want to add all of their telephone numbers to a different column. That is, multiple columns (depending on the number of telephone numbers) for each customer/row. How can I achieve that?
I want my output to be
CUSTOMER ID, FIRST NAME, LAST NAME, TEL1, TEL2, TEL3, ... etc
Each 'Tel' will relate to a one or more records in the PHONES table that is linked back to the customer.
I want to do it using SELECT. Is it possible?

I have a query that performs a comparison between 2 different databases and returns the results of the comparison. It returns 2 columns. The 1st column is the value of the object being compared, and the 2nd column is a number representing any discrepancies.What I would like to do is use the results from this 1st query in the where clause of another separate query so that this 2nd query will only run for any primary values from the 1st query where a secondary value in the 1st query is not equal to zero.I was thinking of using an "IN" function in the 2nd query to pull data from the 1st column in the 1st query where the 2nd column in the 1st query != 0, but I'm having trouble ironing out the correct syntax, and conceptualizing this optimally.
While I would prefer to only return values from the 1st query where the comparison value != 0 in order to have a concise list to work with, I am having difficulty in that the comparison value is a mathematical calculation of 2 different tables in 2 different databases, and so far I've been forced to include it in the select criteria because the where clause does not accept it.Also, I am not a DBA by trade. I am a system administrator writing SQL code for reporting data from an application I support.

Hi,New to .Net and SQL. I have two tables that I have joined together. RentalControl_Main has the rental informationd and an Adjuster ID that links to the ADjuster table and the adjusters name. I am trying to create a report that gives the "Single" adjuster name and the totals for all of their contracts. I have a details report that gives each contract info. for each specific adjusters rentals. However, I want to just list the adjuster once and give all of their totals. In my SQL statement I have all of it written out and just need to knowwhat to do in place of 'Alex Early' that will give me all of the distinct adjusters.Do I need to code this on the page with a do while loop?Appreciate any help.SELECT SUM(dbo.RentalControl_Main.Rate) / COUNT(dbo.RentalControl_Main.Rate) AS AmtAvg, SUM(dbo.RentalControl_Main.DaysBilled) / COUNT(dbo.RentalControl_Main.DaysBilled) AS DayAvg, SUM(dbo.RentalControl_Main.Rate * dbo.RentalControl_Main.DaysBilled) / COUNT(dbo.RentalControl_Main.Rate) AS TotAvgFROM dbo.RentalControl_Main INNER JOIN dbo.RentalControl_Adjuster ON dbo.RentalControl_Main.AdjusterID = dbo.RentalControl_Adjuster.AdjusterIDWHERE (dbo.RentalControl_Adjuster.AdjusterName = 'Alex Early' AND (dbo.RentalControl_Main.DateClose IS NOT NULL) AND (dbo.RentalControl_Main.AgencyID = '2')

I am a beginner with SQL, so please excuse any ignorance here.
Under SQL 6.5, when executing a SELECT DISTINCT query against a table in a certain database, the results were returned alphabetized. Now, after migrating the database to SQL 7.0, the same query does not return the results alphabetized. If I add an index for the column specified in the query to the table, the results come back alphabetized. Is there any way to correct this other than adding indexes for all columns in all tables that are queried in this manner?
TIA,
Paige

Hello,
I want to select all the customerIDs where an email address exists. Easy: select customerid from customers where emailaddress = @emailaddress
Now I want to use the resulted customerIDs from the above query as a parameter to select all the email addresses with emailstatus equal to 3.
How do I create this type of while statement in a stored procedure? I prefer to not create a temporary table.
My idea was to do it like this:
select emailaddress from emailaddresseswhere emailstatus = 3 and customerid = (select customerid from customers where emailaddress = @emailaddress)
This doesn't seems to work. I get the error:
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
thanks

I have a pretty big SQL query with a one to many sort of relationship...
There are client accounts that we're reporting on. Each account has four different historical categories attached. Each historical category can have maybe fifty entries in each, sorted by date.
I need to figure out how to grab the unique accounts and show only the three most recent results per each historical subcategory with the account... the three most current results from each of the four subcategories, displayed by the parent client account number.
I've created four views to isolate the subcategories as a start, thinking I could bring them into a parent query ...
but my question would be... how do I generate JUST the top three historical transactions by account number? If I select TOP 3, I get only the 3 newest in the MASTER LIST, not per client account, which is what I need to do.
Does this make sense? I could really use a good SQL helping hand with this one.
Thank you!
