I have a database that holds student details in one table and their scores in particular subjects in another. The tables are linked through ID. The subjects table looks like this. (example)
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.
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 trying to build a query where I want to extract the sum of the scores for each code MCC and get the percentage over the sum of all the scores over the last 90 days
select MCC, sum(score) as total from scores (select Datediff(day, creationdate, getdate()) as Q from scores where Datediff(day, creationdate, getdate()) <90) group by MCC
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.
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

ok can someone tell me why i get two different answers for the same query. (looking for last day of month for a given date)
SELECT DATEADD(ms, - 3, DATEADD(mm, DATEDIFF(m, 0, CAST('12/20/2006' AS datetime)) + 1, 0)) AS Expr1 FROM testsupplierSCNCR I am getting the result of 01/01/2007
"Error: 8624, Severity: 16, State: 1 Internal Query Processor Error: The query processor could not produce a query plan. For more information, contact Customer Support Services."
I have traced this to an insert statement that executes as part of a stored procedure.
INSERT INTO ledger (journal__id, account__id,account_recv_info__id,amount)
There is also an auto-increment column called id. There are FK contraints on all of the columns ending in "__id". I have found that if I remove the contraint on account__id the procedure will execute without error. None of the other constraints seem to make a difference. Of course I don't want to remove this key because it is important to the database integrity and should not be causing problems, but apparently it confuses the optimizer.
Also, the strange thing is that I can get the procedure to execute without error when I run it directly through management studio, but I receive the error when executing from .NET code or anything using ODBC (Access).
Hey, i've written a query to search a database dependant on variables chosen by user etc etc. Opened up a new sqldatasource, entered the query shown below and went on to the test query page.

However, as you can see, the original select query is run twice and joined together.What I was hoping for is this to be done in the original query without the need to duplicate the original query.
I'm trying to find the command to open up an odbc conection inside sql2005 express. I only have ues of an odbc connector, we're conection to remedy. We will eventually be using stored procedures to extract the data we need from remedy and doing additional data crunching. I'm a foxpro programmer so once I get the correct syntax for making the odbc connector I shold be ok. Also I need a really good advanced book on sql2005. The type of book that would have my odbc answer. I've spent all morning trying to find this information and was unable to.
Thanks in advance

We have a issue with a MDS server that have been over us for a couple of days, the original error msg from SQL Server Engine is the one "The query processor could not produce a query plan" but the ones we get on the Excel-Addin are "Sequece contains no elements" or "The value cannot be null" T
• Using Microsoft SQL Server 2012 (SP1) - 11.0.3393.0 (X64) for 6months on this server without issues
• Two weeks ago we started to have 2 errors: "Sequence Contains No Elements" | "The Value Cannot Be Null"
• We are using the last version of Excel Add-in
• We try to reinstall the MDS feature
• If I backup/restore MDS database to other server it works
• We updated to SQL 2012 SP2 + CU4 but the error persisted ...
Looking at the MDSTraceLog we are routed to the this msg

how do I get the variables in the cursor, set statement, to NOT update the temp table with the value of the variable ? I want it to pull a date, not the column name stored in the variable...
create table #temptable (columname varchar(150), columnheader varchar(150), earliestdate varchar(120), mostrecentdate varchar(120)) insert into #temptable SELECT ColumnName, headername, '', '' FROM eddsdbo.[ArtifactViewField] WHERE ItemListType = 'DateTime' AND ArtifactTypeID = 10 --column name declare @cname varchar(30)
-- 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.
do i need to nest a query in RS if i want a calculated column to be compared against a multi value variable? It looks like coding WHERE calcd name in (@variable) violates SQL syntax. My select looked like
SELECT ... ,CASE enddate WHEN null then 1 else 0 END calcd name FROM... WHERE ... and calcd name in (@variable)
When viewing an estimated query plan for a stored procedure with multiple query statements, two things stand out to me and I wanted to get confirmation if I'm correct.
1. Under <ParameterList><ColumnReference... does the xml attribute "ParameterCompiledValue" represent the value used when the query plan was generated?
2. Does each query statement that makes up the execution plan for the stored procedure have it's own execution plan? And meaning the stored procedure is made up of multiple query plans that could have been generated at a different time to another part of that stored procedure?

I have two tables .. in one (containing user data, lets call it u).The important fields are:u.userName, u.userID (uniqueidentifier) and u.workgroupID (uniqueidentifier)The second table (w) has fieldsw.delegateID (uniqueidentifier), w.workgroupID (uniqueidentifier) The SP takes the delegateID and I want to gather all the people from table u where any of the workgroupID's for that delegate match in w. one delegateID may be tied to multiple workgroupID's. I know I can create a temporary table (@wgs) and do a: INSERT INTO @wgs SELECT workgroupID from w WHERE delegateID = @delegateIDthat creates a result set with all the workgroupID's .. this may be one, none or multipleI then want to get all u.userName, u.userID FROM u WHERE u.workgroupIDThis query works on an individual workgroupID (using another temp table, @users to aggregate the results was my thought, so that's included) INSERT INTO @users SELECT u.userName,u.userID FROM tableU u LEFT JOIN tableW w ON w.workgroupID = u.workgroupID WHERE u.workgroupID = @workGroupIDI'm trying to avoid looping or using a CURSOR for the performance hit (had to kick the development server after one of the cursor attempts yesterday)Essentially what I'm after is: SELECT u.userName,u.userID FROM tableU u LEFT JOIN tableW w ON w.workgroupID = u.workgroupID WHERE u.workgroupID = (SELECT workgroupID from w WHERE delegateID = @delegateID) ... but that syntax does not work and I haven't found another work around yet.TIA!

*Before* I actually call up Microsoft SQL Customer Support Services and ask them, I wanted to ping other people to see if you have ever ran into this exact error
"Internal Query Processor Error: The query processor could not produce a query plan. For more information, contact Customer Support Services."
I would have searched the forums myself, but at this moment in time, search is broken :(
If anyone has run into this error before, what conditions would exist that this could happen? That is, if I can sniff this out with suggestions from the community, I would be happy to do so.
It is an oddity because if I alter a couple subqueries in the where clause [ i.e., where tab.Col = (select val from tab2 where id='122') ]to not have subqueries [hand coded values], then the t-sql result is fine. It's not as if subqueries are oddities... I've used them when appropriate.
fwiw - Not a newbie t-sql guy. ISV working almost daily with t-sql since MS SQL 2000. I have never seen this message before...at least I don't recall ever seeing it.
Thanks in advance for other suggested examination paths.
Hi all I'm using Sql server 2000 and sometimes i need to run my Queries in Query analizer before using them in my application just to test them...BUT most of the time when i run a query in query-analizer for second time ,query analizer populates the result (records) more quicker then the first time. Apparently it caches the query !!! i don't know but for some reasons i dont't want this , so how can i prevent Query-analizer from doing so? Thanks in advance. Regards.
I have a vb.net page that I need to display a list of employees who work in a specific office, based on a MatterID passed in a query string. But, I don't know how to get a value returned from one sql statement into a second. Here's what I'm trying to do... From the QueryString, we know that the MatterID = 4 ( xxx.aspx?MatterID=4) Knowing that the Matterid=4, I query the database to get the OfficeId for that MID (Select OfficeID from tMatter where Mid=4) ~This returns an OfficeID of 6 So, then I need to do another query to get the employees where OfficeID = 6 (Select EmployeeID from tEmployees where OfficeID = 6) How do I do these in one query, or how do I use the Calculated Value for the OfficeID in the 2nd statement?
THis is so annoying. I have 3 ADO executes in my program. THe first one creates a view, the second one performs an outer join on that view and returns a result set, the third execute drops the aforementioned view. THe program that is using this is installed on about 200 computers scattered across Germany and Italy, all querying the same MSsql server 7.0. THe queries run quite quick when few users are actively using the program (after hours for example). however in the heat of the day performance goes up and down dramatically with identical queries taking from 1 to 20 seconds to return their result set. Now I initially thought 'bandwidth issue out of our server'. However I noticed that if I take those three queries and run them from the sql server enterprise manager( running on the same computer as the aforementioned program) then the queries run instantly and the data is in my result pane in less than 2 seconds ALWAYS....even when the program is dogging it with 20 second delays before the result set returns. I know it is hanging on the return of the result set as I put a stop after before each ADO execute in order to check which one was eating up my time. Why is there this dichotomy between running the queries from my enterprise manager versus running them from an ADO object. Both are using TCP/IP (no named pipes involved). I havent monkied with the attributes of the ADO result set so they are all set to default. I have used the sql server profiler to trace these queries and they always run in less than 33 milliseconds. THe duration is also never more than 33 milliseconds. THis stinks of a network resource issue but what always leads me somewhere else is how consistent the performance of the enterprise manager is when it runs the exact same three queries.

Here are the 3 ADO executes: conn.Execute (sqlstr_create_view) Set resultset1 = conn.Execute(sqlstr_get_providers_by_DMISID) conn.Execute (sqlstr_drop_view)
