Patient Query... Pls Help

Aug 27, 2007



Hi Guys,


I have got a table of patients where each patient has got a unique patient number.There are different services which a patient can undertake such as resthome, dementia etc.

Here is the sample data

Service patientNo startDate EndDate

resthome 12 01/04/2003 03/05/2003

resthome 13 12/9/2004 13/10/2006

Dementia 44 12/08/2002 13/01/2004

dementia 12 05/05/2003 06/12/2006

................................. ............ ................................

Each patient has got a start date when he started undertaking that service and end date when the service finished .

Now I need to count total patients for each catagory but here is the main issue....

A patient can move from one servcice to another but cant be in two services at the same time and I need to count the most recent service which the patient is currently enrolled in..



How do I do that????

Pls help me guys as you have always done:wow:



Thanks

Concatenation Of Patient Name Question

Jul 16, 2007

I have a report built that returns patient information. My code to concatenate the patient name fields (last name, first name, middle name and surname) work fine unless the middle name or surname fields are null, then it returns the concatenated patient name field as null. The code is posted below. Is there an easy method to determine if the field is null and then apply the correct logic to concatenate the name with the elements that are not null?





ltrim(rtrim(srm.patients.patient_lname))

+ ', '

+ ltrim(rtrim(srm.patients.patient_fname))

+ ' '

+ ltrim(rtrim(srm.patients.patient_mname))

+ ' '

+ ltrim(rtrim(srm.patients.patient_sname))

as SRM_PatientName

Store Proc - How To Get Patient Status As Output To Form

I am using below code to get patient status as an out put to my form. not sure whats happening but each time I run this its not executing my last "IF" if set to "N" show me N if not show me "Y" but it is by passing my first "IF" condition and jumps to last?

Error: 8624 Internal Query Processor Error: The Query Processor Could Not Produce A Query Plan.

May 24, 2007

SQL Server 2005 9.0.3161 on Win 2k3 R2



I receive the following error:



"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)

VALUES (@journal_id, @acct_id, @acct_recv_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).

SQL Server 2012 :: Adding Count To Query Without Duplicating Original Select Query

Aug 5, 2014

I have the following code.

SELECT _bvSerialMasterFull.SerialNumber, _bvSerialMasterFull.SNStockLink, _bvSerialMasterFull.SNDateLMove, _bvSerialMasterFull.CurrentLoc,
_bvSerialMasterFull.CurrentAccLink, _bvSerialMasterFull.StockCode, _bvSerialMasterFull.CurrentAccount, _bvSerialMasterFull.CurrentLocationDesc,
_bvSerialNumbersFull.SNTxDate, _bvSerialNumbersFull.SNTxReference, _bvSerialNumbersFull.SNTrCodeID, _bvSerialNumbersFull.SNTransType,
_bvSerialNumbersFull.SNWarehouseID, _bvSerialNumbersFull.TransAccount, _bvSerialNumbersFull.TransTypeDesc,

[code]...

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.

SQL Server 2012 :: How To Pull Value Of Query And Not Value Of Variable When Query Using Select Top 1 Value From Table

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

Query Fails With Invalid Column Name But Succeed As Sub-query With Unexpected Results

Sep 22, 2015

-- 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....?

Why The Query Works In Query Analyser And Doesn't Work In Reporting Service ?

Apr 30, 2007



Hello everybody,



I'm developing a report using the following structure :



declare @sql as nvarchar(4000)

declare @where as nvarchar(2000)



set @sql = 'select ....'



If <conditional1>

begin

set @where = 'some where'

end



If <conditional2>

begin

set @where = 'some where'

end



set @sql = @sql + @where



exec(@sql)



I run it in query analyser and works fine, but when I try to run in Reporting Services, Visual studio stops responding and the cpu reaches 100 %.



I realize that when I cut off the if clauses, then it works at Reporting services.

Does anybody know what is happening?

Why the query works in query analyser and doesn't work in Reporting Service ?



Thanks,



Maurício

Transact SQL :: Adding Results Of Query To Another Query Via Dynamically Added Columns

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?

SQL Server Admin 2014 :: Estimated Query Plan For A Stored Procedure With Multiple Query Statements

Oct 30, 2015

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?

<ParameterList>
<ColumnReference Column="@Measure" ParameterCompiledValue="'all'" />
</ParameterList>
</QueryPlan>
</StmtSimple>

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?

End Sub
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
I executed the code successfully and I got a box which asked for "Enter the query string".
I typed in the following: EXEC dbo.SalesByCategory @Seafood. I got the following box: Query attempt failed. Must declare the scalar variable "@Seafood". I am learning how to enter the string for the "SQL query programed in the subQuery_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnQuery.Click" (see the code statements listed above). Please help and tell me what I missed and what I should put into the query string to get the information of the "Seafood" category out.

Thanks in advance,

SP To Perform Query Based On Multiple Rows From Another Query's Result Set

Nov 7, 2007

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!

Query Designer Encountered A Query Error Via Enterprise Manager

I am trying to run queries against any of the user tables in my MS SQL 7.0 database. I get a message the Query Designer encountered a query error.
We have tried rebooting the SQL Server and I am still getting these messages. Also, the SQL error logs look fine - all database

into production in a few days.

The Merge Process Failed To Execute A Query Because The Query Timed Out

After manual syncronization it goes under control.

Could anybody explain the relationship between converting error and timed out query?

If this is poor connection's problem how can I increase the query timeout for the process?

SQL 2005 V9.0.2047 (SP1) - The Query Processor Could Not Produce A Query Plan

May 15, 2006

Hi Everyone:

*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.

Prevent Query-Analizer From Caching The Query Execution?

Apr 11, 2008

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?

How To Use Value Calcuated In Query In Subsequent Query, All Based On Value In Querystring?

Jun 5, 2008

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?

Query Analyzer Runs The Query Instantly But ADO Can Take Forever???

Aug 29, 2001

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 is my slightly edited connection string
Public Const connection_string = "Provider=SQLOLEDB;Server=000.000.000.000;" & _
"User ID=johndoe;Password=janedoe;Network=dbmssocn;" & _
"database=fidojoe"

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)
